Teach Your Router New Tricks With DD-WRT
snydeq writes "InfoWorld's Serdar Yegulalp offers an in-depth look at DD-WRT, open source router firmware that can 'breath new life — and advanced features — into your old wired or wireless router.' Quality-of-service controls, iptables-based firewall, IPv6 support, DNS controls, Kai Daemon for allowing game console network tunneling, and a host of features for using your router as a public-access hotspot are among the many possibilities for hacking your router with DD-WRT."
welcome to 5 years ago dipshits
I know nothing about the project, but I wonder whether your hardware is fast enough to do whatever pppoe needs done to push data faster. Isn't your DSL link limiting the speed to what you see? How did you verify that it's DD-WRT's problem? Just asking.
A successful API design takes a mixture of software design and pedagogy.
I just installed it for the first time on my router yesterday (linksys e2000.) Easy to install and it's working well. Good QOS is nearly mandatory in my house.
Since when has dd-wrt been "Open Source?" It's very much closed-source. OpenWRT is actually open source, as in, you can download the code, modify, and compile it yourself. dd-wrt is closed, and often includes proprietary drivers.
You can also enable rflow (which appears to match NetFlow v5) on DD-WRT routers, so you can find out who's hogging the bandwidth.
This is old news, also DDWRT is a closed source solution that for some routers you have to pay for features. Openwrt has much more for the price and if something is wrong you can fix the bug yourself.
I used DD-WRT for some time, but if you want QOS bandwith managment for games (which was what I was really after), you have to buy your way into the forum where a premium version can be downloaded.
Anyway, after some more looking I found 'Tomato' which fitted what I was looking for a lot better. Feel free to try it for yourself.

Even better than stock Tomato (who's GUI and features are awesome) is TomatoVPN that includes a build of OpenVPN!
Assuming you are serious about "simple", no problem.
Even stock routers come with web servers(the config webpage being the interface of choice) and OpenWRT or DDWRT offer webservers that are a touch more customizable.
The only downsides are that running a webserver can be an excellent way of discovering how little RAM most routers have, and you either have to get one with USB host support, or scrounge enough GPIO lines to bodge in an SD card interface, if you actually want to serve any nontrivially sized stuff.
It is also, of course, Not Recommended to let the box that handles minor functions like all your internet traffic, DNS, etc. get 0wn3d. So don't do that.
One thing that the various WRTs did give me was proper control of iptables so I could do things like redirect to squid and the like. Yes, you won't get goodies like openvpn on slim hardware, but still, even having a bit more direct control of the networking that is there can be a boon.

When there are all these good firmwares around, why do so many companies stick with their shitty proprietary ones?
(Also applies to cheap NAS boxes; I just bought one where half the text was translated terribly from chinese, and the other half not at all -- with the aid of google translate I eventually figured out that to edit a user's password I had to click "Clam Party"... would just sticking freenas on it be so hard? :( )
I mod down anyone who says "I will be modded down for this", regardless of the rest of their comment
The dude that runs this project is a douche. Don't support it. I attempted to build his stuff from scratch to see if it's even possible . Build scripts were poorly documented, and I knew after I had downloaded like 8GB of source that something was fishy.
It may work for you - but this guy does very little to help openwrt.
Please use openwrt - or x-wrt.

I looked into a Buffalo router that comes with DD-WRT preinstalled and Buffalo tech support. But the latest firmware is almost 2 years old. Surely there's been bugs and vulnerabilities in it found since then, but no patches.

How do I replace the DD-WRT firmware that came with a Buffalo router with openwrt or x-wrt?

Which FOSS router OS/SW can I use to replace what's installed on an Astaro router? I stopped paying for the annual license so it stopped working, but the HW is just fine. Twin WAN, firewall, antivirus, internal VLANs, VPN... but closed and locked down. I'd still pay to subscribe to patches, but not on something that just disconnects from the networks when I'm late.

Leave it to InfoWeek to be both completely confused and 5 years behind the times.
To wit, this article with the same premise from Lifehacker in 2006. And that was before DD-WRT sucked.
First, the author's router is not "an old router". In fact, it ships with DD-WRT. Take an old WRT-54G 1.0 and stick DD-WRT and that would be breathing life into an old router. All you're doing here is using a Buffalo-preconfigured (and encrypted, closed-source) version of DD-WRT.
But more to the point...DD-WRT? Ick. If you want QoS (as the author seems to), you need pay for the commercial version. The QoS in the free version is known broken and has been for quite a while, and there is little motivation to fix it. Also, old routers cannot use the QoS, because you need 4MB or bigger flash. Maybe it works in newer routers but who cares - there are plenty of better alternatives to DD-WRT.
Finally, for Slashdotters, let me say two words that will have you running screaming from DD-WRT: software activation.
Tomato is a fine, free (in all senses) alternative, and I personally love the Tomato-USB version.

I always look at DD-WRT vs OpenWRT like this: DD-WRT is like an improved stock firmware. Sure, it has lots of features that probably aren't available in the preload, but it still just feels like a manufacturer firmware. OpenWRT, on the other hand, lets you go 100% CLI (it didn't even come with a web interface until a few releases ago). In general, if you could do it with a plain old linux box, you can do it just as easily on OpenWRT. For example: I look in /etc/config. In OpenWRT I see human readable, easy to edit config files. In DD-WRT, I see obfuscated things.
I used DD-WRT for years on an old Linksys WRT54GS (I think that's the model) router and it worked great for me. But after upgrading my internet to 100 Mbps I found out it pukes out at around 20.5 Mbps or something like that, haha. Almost wanted to swear at my ISP, and then decided to try plugging straight into the new Cisco modem/router they gave me, and found all the bandwidth I was paying for was there after all. Haha. But plug back into the Linksys and it chokes me back to just over 20 Mbps again. Couldn't believe it.
We need a little more information than just "Buffalo router". If the router doesn't have firmware upgrade page, there's typically some recovery method involving TFTP that allows you to flash a new firmware image.
Tomato totally rocks as long as you need basic router features (and by basic I mean, compared to DD-WRT, it still offers far more features than those that come with stock firmware). I bought an Asus RT-N16 and got tired of its stock firmware - crappy connection, never saw uptime of more than 4 days. Replaced it with Tomato about three months ago and haven't rebooted the router since then. It has all the features I need - mac filtering, vpn tunneling, UPnP, NAS, QoS.
I have a cheap router with an Atheros radio. DD-WRT did not deal with it well at all, with the WiFi connection dropping & very unstable. The router works beautifully using OpenWRT - WiFi included. DD-WRT probably works great with a Broadcom radio 'cause that's where it was born but my Atheros radio router likes OpenWRT much better.
I have nothing to do with any authors or developers but have had a pretty good experience with DD-WRT.
I bought an ASUS RT-N16 on sale some time ago:
http://www.newegg.com/Product/Product.aspx?Item=N82E16833320038
I liked the speed specs and also the USB ports -- I wanted to set up a network printer. The firmware that came with this router was GARBAGE. I mean totally, utterly, completely USELESS. My internet connection would constantly drop, forget about printing or NAS. I downloaded a particular build of DD-WRT and installed it and the router suddenly did everything it was supposed to. It stays up and running for months at a time. I'm really glad I found it.
It's also nice to hear about Tomato and Open WRT. I'll look into those when I need to get my next router -- which I shouldn't need for a good long time.
Yep, Tomato VPN is fantastic. I've been running on an ASUS router for quite a while now.

My experience with DD-WRT for the WRT54GL has been less than optimal. After much tinkering it's stable with the features I want, but it took quite some effort.
If you're considering installing DD-WRT, know that there's a good chance that the "stable" version listed on the main site is probably not your best bet, nor is whatever the router database suggests. Instead, hit up the forums, find the relevant forum for your hardware, read all the way through the sticky posts marked "READ ME" (in the case of WRT54GL the "peacock thread") and if you still feel like going for it, then by all means do.
not that it's an optimal fix - but you can on DD-WRT set a timed reboot cycle.. only problems i've seen with DD-WRT that i would consider a bug is it doesn't do DST changes to the clock except on boot (which screws up time profiles twice a year and hence why i have it set to reboot when they happen).. the other problem is (at least on the version i'm using) iptable entries are backwards when you enter them.
'...if only "Jumping to a Conclusion" was an event in the Olympics.'
Hmm, I have used DD-WRT for that many times, using Linksys WRT54GL routers. I have three of them at home... the main one has the Internet connection (cable) and does the DHCP assignments and NAT'ing etc. A cable runs upstairs to another one that acts as an ethernet switch and wireless access point. I have a third DD-WRT router running as a repeater bridge, to cover the rest of the house with WIFI. Nary a glitch... these routers have been running for years and literally go hundreds of days without a reboot (Well, the repeater bridge isn't on a UPS, so it gets hard booted when the power blinks out, or before we start the generator but that's not often)
I also do this for motels and lodges that are too cheap to buy proper equipment. WRT54GL routers, with DD-WRT. One of my favourite cases is a motel property that needed their network extended across the parking lot to their other building. It's a mickey mouse solution, but it works for them and only cost a few hundred dollars in parts and labour. A wireless repeater bridge across the parking lot (I upped the TX power a little on both routers) that has both ethernet switch ports (with another switch plugged into one of the ports that feeds the rooms) and wireless. The same SSID as the main network too and clients can roam. Nothing goes wrong with this setup unless someone messes with it. (Last time I was called there one of the routers had reverted back to defaults... someone used the reset button)
I'd investigate the laptop as the "hunk of junk". You could reboot the router to force a client to re-establish a wireless link, or deal with the client. It could also be a flaky router in the mix.
are you saying that steve jobs is a douche?
I use dd-wrt on my cisco router, and it is far superior to the previous cisco firmware. Though I am humbled to learn that I went for dd-wrt when open-wrt was sitting right beside it. A look at the wikipedia article indicates that dd-wrt is still under GPL, but tonight I know what I'll be doing; I'll be changing to tomato or open-wrt. A word on the /. article: I am quite surprised at the "hostile" reactions; the concept of tweaking a router with open-source firmware is a fantastic one, and I can easily pardon a small error. Minus the venom, I am grateful to /. and the /. community for (harshly) furthering my education. Now, onto that 30/30/30 process once again. Thanks /., and angry geniuses!

Not exactly "news", both dd-wrt and truly open source open-wrt has been out outperforming stock firmwares for 5+++ years
After reading some of these posts, I'm going to try Tomato when I get bored, but I've got a WRT54GL / DD-WRT setup as well- it's been running for a couple of years without so much as a hiccup. I set it up primarily to bump the TX output for better coverage, and literally forgot about it until now.
I just installed it tonight on and old Netgear WG602 v3 I wanted to make a client instead of using my USB WiFi stick. The GUI is nice with tons of features.

Firmware is already a collective plural -- like software, hardware, and clothing. You don't have "two softwares" or "two clothings" -- you have two pieces of software, or two items of clothing. Likewise, you should write: "When there are all these good firmware packages around..." Also, swearing is impolite. Good points, though.
Fuck dd-wrt. Hasn't everyone switched over to openwrt or tomato these days?
I'm a Toamto-holic. dd-wrt just would not work properly on my Cisco/LinksysWRT160N V3 despite careful configuration changes etc. In frustration I installed Tomato and it worked first try right out of the gate. I had also used it on an older Linksys router and it never gave me any grief. Its features cover off my needs and it's been completely hassle free. Just my own experience.
...wishing I had mod points...
The "CPU" that is used in that device won't actually go much beyond 20mbit. It just simply can't handle faster streams, especially if you're using NAT on your internal network. NAT adds a bunch of overhead. Supposedly the GL can go up to 30mbit as it has a newer processor.
ppoe's not that bad.
I had similar experiences myself, but with a simple TCP/IP router role (eg, not acting as a modem). It was slower than you'd expect, and it had *plenty of free RAM and CPU.
* plenty being relative, of course.
The trouble with OpenWRT is, however, you have to go back to the 8.x White Russian release. 9.x and Kamikaze won't fit into flash smaller than 4mb. This is quite limiting. For example, most Linksys 802.11b/g gear (excepting the WRT54GL) seem to use a 2mb flash.

I found that its speed of dd-wrt (not pppoe, just regular routing) was comparable to the stock firmware on my WRT54g. The problem is, the hardware is just crap. With dd-wrt I looked at the cpu usage, and it was pegging when I was trying to download something. I put some version of Fedora onto an old Deskpro with a couple of NICs in it to make a homebrew router, and it increased my speed about 150%. Just offloading the routing to this box and still using the wrt54g for wireless was a big improvement. And my (hackish) QoS (just service priorities) works 1000% better than whatever crap was on dd-wrt.
Now, that little PIII 733 sits at 0.0 0.0 0.0 no matter what I throw at it. I also put the OS onto a little 2gb CF card, and the little thing boots up fast as heck and its dead silent, and barely gets warm.
I am still using the latest stock firmware. It works fine for me, but I don't want to have to keep upgrading and reconfiguring. So which ones are the stable, simple, etc.? I don't want to have to fiddle with frequent upgrades, reconfigurations, etc.
Ant(Dude) @ Quality Foraged Links (AQFL.net) & The Ant Farm (antfarm.ma.cx / antfarm.home.dhs.org).
Very few consumer routers can handle 100 Mbps throughput across the NAT (well, technically PAT) layer. They simply don't have the CPU power, bus speed, and memory required. I would be interested to know what routers are capable of such speeds and are compatible with the likes of OpenWRT.
I have a WRT54G v5, dd-wrt micro is the only thing that will fit in the damn flash.
Hasn't the Kai support been broken for a while now?
"If it ain't broke, it doesn't have enough features yet"
DD-WRt has QOS settings, but they're function so horribly they may as well not even be there. That, and the hardware in most DD-WRt routers isn't capable of keeping up with more than basic functionality.
...PPTP/VPN (server) is disabled in DD-WRT. That pretty much chokes it.

It would be nice if it had an easy workflow. I.e., instead of editing a whitelist file, you'd have something like:
-user tries to visit an un-whitelisted site.
-the site is automatically added to a "request" list, optionally with a comment from the user
-admin is presented with the request list in a web interface and approves the ones he wants to

The Buffalo WZR-HP-G300NH works for me, with openwrt firmware that is. The default firmware is some kind of modified dd-wrt which has an awful "buffalo" interface and kept dropping packets. I tried dd-wrt as well but that gave the same problem with the choked bandwidth (in contrast with the buffalo firmware), the openwrt firmware is pretty easy to set up on this router and works perfectly for me, allowing the full use of my 120 mbit connection.

My biggest issue is trying to find a router can that run DD-WRT/Tomato/etc, is trying to find a router that can handle 400mpbs+ of WAN LAN Performance.
Are there any high performance routers that support open source?
I've been using Tomato on my WRTGL v1.1 For at least two years now, and It was very much install, configure, forget. QoS works great, and it manages my 40mbps connection with some trouble. (notably, It piles up if you saturate the link at 40mbps for a few days requiring a 30-30-30 reset) Even so, it's infinitely better than the stock firmware.
But does it allow say a wifi router to go from being a wifi g and b to to a wifi n as well?
If it does, then I would pay for that for sure, instead of buying new stuff, just reuse the old one with the firmware update and voila no more junk in the garbage dumps that could be recycled, so to speak.
I'm not sure what you mean, but I've been tunneling IPv6 with OpenWRT for quite a few years now.
Dewey, what part of this looks like authorities should be involved?
Too big, it's gotta be a hair below 2mb to fit on these things :(

Ah. Did you ever had that problem with the stock firmware?
Ant(Dude) @ Quality Foraged Links (AQFL.net) & The Ant Farm (antfarm.ma.cx / antfarm.home.dhs.org).
Yup, I have FIOS and ended up switching to the Verizon-provided router for this reason. The biggest issue with it is the NAT table is limited, but I think I've mostly worked through that.
You can potentially put the router into more of a bridging mode and use your own router (which obviously has to be decent), but that is pretty tricky due to how the whole setup (internet+cable) works.
Cisco has the 800 series routers which are not to be confused with their Cisco/Linksys line. They come with full IOS capability and have enterprise grade features and functionality. Meant for test labs or small enterprise use.
Also, the Apple Airport Extreme is a very capable router, both in terms of dual channel N wireless and high end processor speed, etc.
Neither are compatible with open source firmware, but they are both sub $300 routers which will handle enterprise level bandwidth.

That same question was asked recently:
http://ask.slashdot.org/story/11/09/19/0315258/ask-slashdot-good-gigabit-80211n-home-router
I have used DD-WRT, but from what I can tell, the firmware is built from Open-WRT. The problem I had with DD-WRT is that it is mostly proprietary. Also, the build trees they use from OpenWRT were usually bad so you had crappy wireless drivers most of the time for lots of different chipsets. Perhaps with the exception of the truly ancient BCM chipsets in their WRT54GL implementations of DD-WRT. Those ran pretty well.
But, if you truly want a decent piece of software for doing wireless, I would suggest you check out OpenWRT. Secondly, get a AR7161/AR9283 based wireless hardware model. I would suggest the Buffalo wireless units. They work pretty well. These devices made by Atheros are all very open source friendly so you get a piece of hardware the developers don't have to fight with the manufacturer about intellectual property crapola.
(Which, in my view is what intellectual property is nothing but people who want to own everything and have other sociaopathic and psychopathic tendencies.)
The OpenWRT build system is pretty good too. You can concentrate on the software instead of fighting the build system.
But I stopped using DD-WRT a long time ago. It just isn't a good solution for wireless N and the authors do not appear to be very Linuxl aware. (Although, they are very good at writing javascript to create a nice interface in the browser and just copying whatever build tree from OpenWRT that is the flavor of the day.)

I don't know about 100mbps but I have a Linksys WRT160N running dd-wrt and it happily saturates my 50/50mbps FIOS line. Cost something like $30 as a refurb.

Every sentence I wrote was a complete sentence. Maybe the second was a "comma splice", but I wouldn't call it not a sentence. Go fuck yourself.
How in the hell did my original post get moderated Troll?!?! I am really curious and really want to do it. As far as cracking WEP, that's a no brainer. Done it already. Once you can crack the WEP and get a hold of the router config internals, uploading your own firmware also becomes trivial.
I like both those links immensely. Thanks!
I hold very few opinions. I hold information based on observation and fact. If you wish to disagree, please use facts.
I was only dealing with wired connections, but no.
Wasn't dealing with wireless. The wired connections were being choked down to ~20 Mbps. The annoying thing is, the firmware the ISP provides on the Cisco DPC 3825 (or the device itself?) makes it so wireless connections cannot see any of the wired connections. So things like controlling an iTunes box via my iPhone and the wireless connection were impossible, because the devices couldn't see each other. This was the only reason I tried to keep my Linksys box connected as before. But now I've worked around that by connecting the Linksys to the Cisco via one of the regular connections, and ignoring the WAN connector on the Linksys, and now Linksys wireless clients can see the wired clients just fine, heh. Stupid ISP. "But can your wireless clients connect to the internet? They can? OK, that's all we care about. Any other issues I can help you with?" heh.
Yeah, this doesn't surprise me. It is pretty old consumer gear now.
Thanks for that link!
Considering that it barely gets warm with no fans on the processor, I'm betting it is pretty low. The TDP of that p3 chip is 19.1w, and that's if it is running at full blast. The wrt54g is actually warmer to the touch, just sitting there.
the same problem, yes, which leads me to believe it's a hardware fault, which is Why I still applaud the tomato firmware, as it provides me with more features.

Just an FYI: Newer routers typically need the NEWD2 wireless drivers which old DD-WRT doesn't have. The DD-WRT homepage hasn't been really updated in I don't even know how long and doesn't make any mention of such things. I wrote most of the WRT160Nv3 section of Linksys WRT150N & WRT160N - DD-WRT Wiki after I got mine working and I've never had a problem with it like I had with old WRT54G's. I've never used Tomato and didn't know it was even compatible with the later Linksys models, but if you ever want to give DD-WRT another shot that guide will get you through it.
I've never had a problem using the latest release from ftp://dd-wrt.com/others/eko/V24-K26/. The current latest isn't actually a global release. Go to 17084 and download the one labelled WRT160Nv3.
