Linksys WET11: Bridge 30 Devices To Any Wi-Fi Network
eggboard writes "The Linksys WET11 lets you bridge a wired network with up to 30 devices to any wireless access point that uses Wi-Fi. The utility is enormous: you could build a pseudo-mesh network by pairing cheap Wi-Fi APs with this cheap ($129) Wi-Fi bridge. Before this, the only generic Wi-Fi bridge was proprietary: you'd buy a bridge from Alvarion that paired with one of their hubs, and spend several hundred each. Even the dual-WAP11 bridge approach of last year was wonky and required extra gear (although it can handle more devices than 30 since it's a protocol bridge, not a MAC bridge). I review the WET at O'Reilly's wireless developer's site."
[from Australian slang] Yet another approximate synonym for broken. Specifically connotes a malfunction that produces behavior seen as crazy, humorous, or amusingly perverse. "That was the day the printer's font logic went wonky and everybody's listings came out in Tengwar." Also in `wonked out'. See funky, demented, bozotic.
I was one of the early customers for the Linksys WET11. My hope at the time I bought it was to be able to hook it up to my Xbox game console and use it to play Xbox games online while running Gamespy or or XBConnect on my primary PC, and therefore not have to run any unsightly ethernet from my entertainment center into my computer room (I rent an apartment, and the landlord would appreciate me returning it eventually without too many extra holes).
1 3 - this is the forum for XBC. Look for anything in there labelled WET11.
Obviously, nothing is ever that simple. I discovered that the WET11 performs some wonky MAC addressing translations when forwarding packets. Seeing as Xbox System Link games depend entirely on ethernet addressing schemes, the WET11 proved to be useless for this - despite Linksys advertising it as a solution for Xbox gaming.
Correct me if I'm wrong - something labelled as a "Network Bridge" should pass packets from one side of the bridge to the other unaltered, and simply keep a table of what addresses are on what side so as to pass packets when necessary between two broadcast segments. WET11 converts all MAC addresses on its "wired" network into it's own address. The reverse is different - it'll reassemble incoming wireless packets based on what I guess was their original IP source, and place the MAC address it replaced with its own back in the packet. Go figure why they go through all the trouble. Of course this behavior is undocumented, so this took several hours of packet sniffing (so blame me, I don't deal with Layer 2 issues every day).
Now, Xbox Live is expected to work at the IP level, but that is'nt out until December. Existing System Link game like Halo only work on a local broadcast segment, using ethernet for addressing while sending out some horribly mangled non-RFC compliant ethernet packets that look like UDP but aren't.
The ethernet mangling caused problems with Gamespy and XBConnect, but I was able to get in touch with the developer for XBConnect and over a nice weekend hacking session we were able to cobble together support for the WET11 in his program - essentially it now has the option to look for the MAC address of the WET11, and retranslate that to that of an Xbox. The funny bit is on the return path from a remote Xbox, it needs to again translate the address of the local Xbox back to a WET11 so your average Access Point knows who to retransmit your Xbox packets to. Every Xbox game needs to go through four translations: two on the WET11 and two on XBC.

It would be a much more interesting read if someone setup a linux (or any other OS) box with a wifi card in it and a wired nic that feeds a hub/switch and NAT'd a bridge.
Go for it. Or wait for someone else to do it. In the mean time, I'll be thankful for the review because it's putting ideas, just like yours, into peoples heads as to what they can do with this new toy.
do not read this line twice.
Ok, the price is pretty cheap. No argument from me there. But, I still can't see the "technical greatness" of this device. Symbol, Cisco and probably Lucent have always had bridges capable of both bridging and AP mode at the same time.
Also, they can all be configured to talk with each other so, I don't understand the proprietary reference. Sure, Symbol et al don't speak Cisco's enhanced WEP but, the Cisco can be configured to use standard WEP so it will speak with the others.
So, besides cost, whats so special about this device? Something else that I am missing is the power output of the Linksys bridge. What is it? Historically, the cheaper Linksys Wi-Fi products have had a lower power output that the others. Is this also true here or does this latest Linksys bridge put out the full 100 milliwatts, as the others do?
