Hacking the Linksys WGA11B ??
« on: March 07, 2006, 06:49:55 PM »

I was just digging through my networking stuff the other day, and found the Linksys WGA11B, so, as with everything I own, had to rip it apart and see what was inside, and I found an undocumented 10 pin serial port, complete with a pre soldered pin header!!
Does anyone know what interfacing can be done with it? and is it possible to make a custom firmware for this device, the current one is a bit buggy.
I will post pics if needed,
thanks

Not hardware hacking related, but I've found that linksys routers have some fun stuff to poke around with. Try port scanning your router from the lan side (aka- scanning 192.168.1.1) you'll find it has some interesting ports open. I've found a hidden menu before, 3 different ways to get to the settings screen, and some other stuff I had no idea wtf was going on with.

Good luck though, and I think I might crack mine open to see if it has anything like that (BEFSR11)

Its actually not a router, its a ethernet to 802.11b wifi device


As far as your router goes, some more info on what you found would be nice, and I know alot of linksys routers have serial ports, but it takes a 50 dollar IC to make it control anything,

http://yasha.okshtein.net/wrt54g/   for example


but I really am looking for info on the port on the WGA11B

thanks

the port is likly used for the Red box when someone forgets there admins password they can get better access to the device and re-set with that.

also reviving dead devices from a bad Flash of new firmware.

So cutome firmware is possible .. is just might not be worth the time to do it as nothing will be gained from it.

WRT54G(s) / NSLU2 you can gain contraol of the signal and other things so it had an advantage.

Do you have any more info on making a custom firmware? I would like to get this thing to do wpa encryption, and/or lock on only one channel so it doesnt keep trying to connect to my neighbors wifi

sounds like your Neighbors Wifi Access point is better than yours, at least the signal is.

Might want to see if there are updated to it from Linksys .. if they have not added the WPA then you might not be able to.
Lot of settings can be hard set on most routers and cards. Have you tried that?

also check out sourceforge and see if there is someone already working on firmware for that card. If not see if they are working on one for something close. Looking through there change logs will give you an idea about what it takes.

actually, they dont have the wga11b, just a router, which is unencrypted, and very weak signal, and mine is encrypted(had to downgrade from wpa to wep for this POS), but the wga11b's default action is to connect to an unencrypted ap, or another wga11b, and it doesnt want to keep a connection to my router, a wrt54g
but thanks, I will try sourceforge

Reason I am pointing you that why is, if someone has upgraded the device they would have most likly placed it there.

1 knowing how to program is going to be a big thing.
2 cross plait form compiling know how is needed
3 unpacking and re-packing BIN files for laoding into the device.

I done this and its not easy but I also dont do it day to day.

I do have experience programming, and if someone could help me decompile the firmware on it/point me in the right direction, such as sites/progs, that would help greatly.

decompile...you arent serious are you?  first, you have to know the ISA that the processor is built off of...do you know that?  second, you would be lucky, at best, to disassemble the firmware.  from that point on you will have to step through the assembly code one line at a time taking note as to what is happening...because you will not get any type of "readable" labels or aliases from the disassembled firmware...but you probably knew that.

dude.
