Creating A Super-Router (For Free)
Aaron writes "Kind of an interesting discussion and story over at Broadband Reports about the flurry of vendors releasing modified Linux based firmware updates for the Linksys WRT54G router. The updates bring a whole new level of functionality Linksys couldn't be bothered to incorporate. Among a long list of free improvements is the incorporation of bandwidth management, allowing users to end the days of choppy VoIP conversations without swapping out hardware."
Here's a detailed guide on how to do just that.
For those of you that don't know, and are interested, Wondershaper can be found HERE.
It is AMAZING.
Sample config:
DOWNLINK=6000
UPLINK=200
DEV=eth0
# low priority source ports
NOPRIOPORTSRC="6881 6882 6883 6884 6885 6886 6887 6888 6889 80"
Sets those ports to only use up 200k of my 256k upstream leaving me the rest for SSH etc. I never have any problems w/my remote connection speeds this way. It's fantastic.
I have only had a single problem, recently, with Debian unstable... It removed my libatm for some reason. I reinstalled that and all was well.
Highly recommended for everyone, not just users of this "hackable" router.
Linksys isn't bad at updating their firmware. I was able to update my cheap wireless router so that it supports WPA for free.

Is that linux based system available for the WAP as well? (Dunno if it's got enough RAM & flash memory to run&store it...)
Cisco products are expensive but pretty damn stable.
Your "open source" comment is stupid, Cisco uses ASICs and other hardware level goop for much of their routing. Unless you're going to open a chip fab plant and start open sourcing your chips... need I say more? (There are some exeptions, ala the Cisco PIX 525 firewall, basically a PC motherboard with some custom stuff for failover etc.)
"Open Source cures cancer!" blah blah blah Use the right tool for the job, you won't paint yourself into a corner and you leave your options open, lad.
Trolling is a art,
I like my ClarkConnect box better. All it cost me was a pile of old parts that were headed for the dumpster and a ~300 MB download.

Netgear's support web site contains the source for some of their routers (eg the DG834 series). Cool idea for people to be able to add their own features.
I replaced my WET11 with a second WRT54G with modified firmware which allows me to set it to client mode like a WET device. I use this to connect to my TiVo and Xbox.
The newer revs of firmware will have WDS which allows the routers to bridge to each other and client devices to connect to them. However, I think it does half the throughput.
I just got Vonage, and I plan using Wondershaper once these firmwares mature a little bit more.

I use a Netgear DG834G which appears to run linux 2.4.17 on its MIPS malta processor.
You can download a bundle of the packages it uses from netgear but they are not configured so its
hard to patch or hack with it cos you'd have to
redo their work.
This seems at odds with the GPL , on the grounds
that if you use GPL'ed code you must publish not
just the original source but your modifications as well . or am i wrong ?
The firmware upgrade patch is easily dissasembled and i've managed to hack the file system (cramfs) out of the firmware . So there is a possiblilty
that modifying the filesystem might open up safer
modification by making telnet accessable. but i'm
too much of a chicken to try it and i expect the
checksum would fail.

6to4 is your friend. For linux please refer to the Linux IPv6 HOWTO
For windows, go to your network configuration. Find your lan, and enable their IPv6 driver. XP only.(SP1 only?) I believe it self configures to use anycast, so that should be it.
Mac....do not know. I assume something along the lines of what linux does will work.
Good luck.

The difference between the Cisco routers and the low-end DLink/NetGear are that the former are much more stable, and a lot of the routing logic is hardware based so they are able to scale & perform much better than the latter.
I don't know why they would want to hold back Linksys development though, especially for things such as IPv6. They are a smart company, so I cannot figure out why they think holding back development of Linksys is going to advance their cause of spreading the use of IPv6.
There are lots of people who use Linksys, but are not willing to spend a lot of extra cash just to get a Cisco box so they can do IPv6. And the more people that demand IPv6, the more ISPs are going to have to buy new Cisco hardware to upgrade their higher-end routers.
If that number is X, it's now X+1 - I just ordered one to replace my Belkin wireless router, which replaced the Netgear router that started giving off "the Brown Smell" before dying completely.
Why? The Belkin is a nice piece of kit, but it doesn't have the features I need. The Netgear had most of the features, and was actually pretty okay. The Linksys doesn't have the features I need, but looking at the hacked firmware versions available it'll be soup and nuts to give it those features, and the price is right.
Someone said that they may be hurting sales of their more expensive products which have the advanced features these hacks are adding. I don't believe that's true. People who need those features badly (from a business sense) will still buy the expensive kit; they need the support. Cheap-ass hobbyists like myself will buy the cheaper kit and hack it. So all they're doing is persuading me to buy their cheap kit over someone else's cheap kit, and sales are sales...
Sveasoft is working on a mesh firmware for the Linksys WRT54G. We hope to have a preliminary release sometime in late March.
Life is a tale told by an idiot, full of sound and fury, signifying nothing.

I have a friend who used to work at Cisco. After the Linksys acquisition, they put management barriers in place so that people from the Cisco side of the house would be blocked from "infiltrating" and/or influencing Linksys with anything Cisco-related.
Cisco (at the time anyway) wanted to keep them "as is"... dunno if that's still the case or not.
Mesh routing is on the list of things to do with some progress being made in that direction already.

It's possible, too with that router, I own myself a Ravotek 54G Router but I use the Belkin software atm. because of failures in the firmware from Ravotek.
(Should be even more cheaper than the Belkin-Router, but seems to have the same ingredients.)
But therefore you have to recreate a firmware, or just a kernel-module, I didn't got the Linksys FW run until now, but that could be done by rewriting the header.
Take a look on the seattlewireless.com homepage, they have some posts about the belkin router.

"a lot of the routing logic is hardware based"
No it isnt. Not in a $2000 cisco.
You need a (starting at)$15k cisco for that.
The $2k ciscos are all bottom-end ciscos which do everything in CPU and software.
Linksys equipment won't be running Cisco's IOS, but that doesn't mean it's no good. Pretty common practice for Cisco, there are quite a few companies they've eaten just to cover a particular niche. The 675/678 DSL router sold around 1999-2002 was the same way. They took over the NetSpeed product line, and only changed the sticker on top of it.
Identical in every way, but it let them sell a budget box without dropping the price on anything that runs IOS, since this one ran a dumbed-down version called CBOS. Oh, and it let them eliminate a competitor before they could expand into a bigger threat.
That feature is already being worked on, and will show up in a future version of the sveasoft firmware.

There are no stupid questions...just stupid people.
I had these same issues after upgrading from version the 2.03 that came with it, to 2.1... I went back to 2.03 as a result, which is available here.
