Sorry if my last post sounded misleading. I was only suggesting that the radio firmware may be one reason for some people's low wifi strength.
I don't think there is really a problem with any GB radio per se. There could be a whole number of reasons why the wifi might not work well. Note this list is not exhaustive:
1. The router is not talking the wifi radio hardware properly
2. The wifi radio is not talking to ROM software properly
3. The ROM software is not reporting the correct information to the user
4. The ROM software has been tweaked to drop weak signals earlier than other ROMs (I remember the Virtuous Unity ROM initially had this issue, later fixed)
The reasons for these may be numerous too (list also not exhaustive):
1. The radio firmware version may not be best matched to the environment. (Bear in mind other radio functions are affected by the firmware version like 2G and 3G signal strength, 3G/4G data speeds, bluetooth, gps etc).
2. There is an incompatibility between the radio firmware installed and RILs in the ROM.
3. There are some other settings in the ROM that need tweaking.
Since there are so many variables, the more relevant details and reports of what has been tried there is, the easier it might be for someone to try and figure out what the issue is.
I'd suggest anyone with a weak wifi problem reporting a few details to see if any patterns emerge like: did you do a full wipe before installing the ROM, what radio firmware version are you using, did you match rils or use the stock ROM ones, did you try any other radio versions and what happened if you did? Also did you flash any mods or adjust any settings (particularly in relation to the wifi)?
And just to repeat: as far as I know, there isn't a problem with any GB radio. You need to make sure that it's the right radio for your environment and the ROM you're running.
