[FIX]WiFi Fix

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).

I could be wrong but i don't think its a software issue, i have had two sony phones and they both had poor wi-fi signal and range compared to other's like htc etc.

i just think sony uses poor wi-fi modules in xperia devices, because the same conversation was going on with my last xperia play and that never really got fixed.

Try using both in conjunction?

Final WiFi fix

alivanov79 said:
If you have a WiFi permanently disabled or very weak, try to do it:

Open the file /system/etc/firmware/wlan/prima/WCNSS_qcom_cfg.ini in text editor.

Change the line gEnableBmps = 1 to gEnableBmps = 0

Save and reboot

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

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)

Doesn't work for me.
Have you used it together with alivanov79 his fix?

Hi!, no, I don't use it with alivanov79 fix (I'm not confortable with battery drain).
If you use another fix, my suggestion is to use them or only use this changes or made tests... (I was reading a lot, getting helpfull info&solutions, tuning them and making T&T)...

Is strange if it does not make sense on you... Can you explain a bit more your scenario?

Some tips to take into account:
- Don't believe on status bar wifi bars
- I supose you checked your router:
- Channel not too much overlaped (use wifi analizer or similar). Change to an unused/more free one (not permit other channel overlap you with more power...)
- If your router is using HT-40 (20/40MHz channels), try to fix to 20MHz...

- Make test with some tool (file copying over local network instead: from desktop to mobile with ES explorer for example)
- Check that your mobile as no issues with resources (no free RAM/paging, local storage ko, CPU too busy,...)

- If you have other tweaks, coming from ICS, please forget them:
- build.prop... (tcp.xxxxx, etc.)
- init.d tweaks... (/sys/xxxxx, etc.)
- sysctl...(ip.xxxx, etc.)

-...

Just an over the fly numbers:
Before,
I got 1.5-1.7MBps file copy from my file server. Close to router.
Got some drops/cuts from the next side room to router 1 wall-5meters: 1.1-1.3MBps filecopy
Got a lot of disconnections/drops next in the terrace close to the above room: 500KBps-800KBps

After,
Got 2.35-2.52MBps close to router
Got 2.2-2.4MBps close to the next room. No drops
Got 1.9-2.1MBps in the terrace. No drops.

I also changed to 20MHz channels on the router.

I tried it with only your fix. I have tried the fix from alivanov79 before but it didn't work.

The first step is to change gAPMacAddr=GET_FROM_YOUR_CONFIGFILE.
I don't have GET_FROM_YOUR_CONFIGFILE. I have got some numbers in place, I geuss my MAC adress.

I have added the last two lines in build.prop

The router setting are set correctly and I don't have any apps running on SP.

Yes, 'GET...' must be changed with your MAC address.
In build prop, ensure you are using. Unix format and probably let an empty trailing line (I suggest usin notepad++).

If you pm me your original files I can do it for you.

What about router & channel?

Pietertje_ · Jul 29, 2013

The build.prop is done.
The mac adress that's in WCNSS_qcom_cfg.ini is different from the one i find in the settings/about phone/status.

Router is set to channel 11. 20Mhz. The router is still on wifi b/g/n because some devices in our house don't support wifi n network.

Sorry, I underexplained it to you... Is the MAC address for your mobile when acting as AP (WiFi port on settings for sharing your connection).
Is not really important, just put a valid one (to ensure copy the same value from your original file).

About your channel, check interferences with WiFi analizer (https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer&hl=es) and choose one that as less interferences/overlaps.

If you fixed to 20MHz (recommended if you have old devices), you can also disable it on WCNSS_qcom_cfg.ini:

gChannelBondingMode5GHz=0

If you still continue experiencing problems, comment out this lines like:

#gVhtRxMCS=2
#gVhtTxMCS=2

Pietertje_ · Jul 29, 2013

I will try tomorrow

bolzass · Jul 29, 2013

Ok!. I will be out and not sure to see your replies. So pm me if you want I help you and will see later.

I have another wifi problem:

I tried connect my SP to Wi-Fi, it's connected and has IP, but transfer data (internet) is not working. So I can't browsing anymore via wifi.
But when I connect my laptop to wifi, everything's okay. Internet is working.

So I think my SP has any Wifi problem. What do u think??
Could u give me some solutions?? Thx

Battery super-drain

Did this trick and somehow it worked. But last night i forgot to turn Wifi connection off, after 8 hours I wake up and realize that my phone has only 47% battery left, compared to ~80% right before I fell asleep. This is terrible to me...

Pietertje_ · Jul 30, 2013

back to normal again.
fix was not working and huge battery drain.
4% per hour in standy.

Edit:
with default settings i have more wifi drops.
so the fix decreased the amount of drops but did not remove them completely.

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.
