I read a while ago that in some linksys (v2.2) routers you can hack the memory to 32MB of ram. has anyone done this any information on this here are my list of chips
Does anyone have the methods for identifying and unlocking this extra ram? I have a WRT54G v2.0.
The method is to open your router, identify the RAM chips, google for a data sheet and figure out its total capacity.
Unlocking is done by setting a nvram value AFAIK. If it fails you can only revert via serial or jtag cable.
But I am sure that it was reported for some v2.2 models to be high RAM (I own one but never did the 'unlock'), I never heard about v2.
OK, for the brave hardware modders out there here is the finished product.
just to keep confusion out of this thread - the original post was about a double sized RAM which was installed in some WRT54G models from factory. Another option is to change the chips yourself.

If you choose to follow these directions you accept any and all responsibility for the state of your router when you're done.
Make sure you have the right chips. if you just go an set the NVRAM settings and you do not have the right chipset, you just created a brick. So pop it open and check

@sonarman,
yes, hence my posting of the chip number, which I cheked on 6 or 8 units till I found the right one.
I replied completely and accurately to the original post from arewhyainn

Thank you !
Yes, the exact right chips are the only ones that work this way.
Linksys must have done a production run using the under-used bigger chips because of supply chain problems.
From my usage patterns, the extra memory doesn't seem to do a lot, but I bet for people running more complex setups it might help.
Out of the 43 units we got used there were about 12 with these chips, so it looks like there were a good sized number of routers that got this bonus ram.
I didn't try to correllate any serial numbers or mac address sequence to see if there was a pattern - the one I have left I posted above, maybe that can help others spot a pattern without a lot of shell-opening. _________________ linksys GSv2, Gv4, Gv2, GLv1, G-TM, Buffalo wbr2, whr, whr-hp, whr-g125, wli-tx4-g54hp, Moto wr850gp, Alix.3C2
