If you have a WiFi permanently disabled or very weak, try to do it:

  1. Open the file /system/etc/firmware/wlan/prima/WCNSS_qcom_cfg.ini in text editor.
  2. Change the line gEnableBmps = 1 to gEnableBmps = 0
  3. Save and reboot

This increases the stability of the WiFi and fixes WiFi from regular stops.

I posted this to a hungarian forum and one guy said it worked for him.
So thanks for the fix. :)

Any issues with battery life after doing this? After googling came across a posting regarding this code and the Nexus 4 where it increased the idle battery usage from 0.5% to 5% per hour.

Don't know about battery drain but this seems to definitely speed up connection to my wlan. Before I would get one or more authentication errors before it would connect but it seems pretty instant now. Will keep an eye on battery and report back.

EDIT: I don't think its helped actually. That said my issues sound slightly different, in that once I'm logged on things are good, but it can take five or six time s to log on if I don't have a good signal.

after a 5th reboot it looks like it is working.
4 hours without wifi disconnecting.

*Edit
Wifi is not fixed...
Again random wifi disconnects.

Yes I'm going to have to retract my statement too. Still get authentication issue.

Seems this is not the magic fix i thought it was, battery drained a huge amount overnight in idle mode when i was asleep. Corresponds to roughly what other people said in other forums about battery draining at about 5% per hour in idle mode as opposed to 0.5% per hour at default setting.

Seems its more an issue of Sony having to optimise WIFI settings to work correctly as it's probably mostly at default Android settings currently (with some changes by Sony, but clearly not enough changes).

    Hi @ll!!. This is my own solution for fixing WiFi range, drops & performance. With these tweaks I have reduced at all drops, and increased the range and performance significantly (absolutely no battery drains...).

    2 files:
    • /system/etc/firmware/wlan/prima/WCNSS_qcom_cfg.ini
      You must change:
      gAPMacAddr=GET_FROM_YOUR_CONFIGFILE
      Click to expand...
      Click to collapse
      at line 76 by your proper value (see your original file)

    • /system/build.prop
      You must add this content to the end of your own build.prop
      net.tcp.buffersize.default=4096,87380,256960,4096,16384,256960
      net.tcp.buffersize.wifi=4096,87380,256960,4096,16384,256960
      Click to expand...
      Click to collapse

    And then reboot & enjoy ;)

    (Tested on .257, but should work in any 4.1.2)

    I found in Xperia z forum that changing the last parameter (before end) to

    ConnectivityThresholdDBM=-100

    Works without battery drain.
    I tried it on SP and haven't had any drop or drain since then. :)

    Mount /sytem as rw in RootExplorer or in some others file managers that support root.
