wi-fi issues

[Guest apometru]

so... when i first bought the acer s500 everything worked flawless until i turned on wi-fi. the problem with it was that it connected and worked with some wifi networks or it connected and didn't work with others. since then i bought a tp-link router to have a working wifi and it did. until i messed up the phone (the phone as rooted corectly and i installed a dpi changer from the market that made my acer go in a bootloop state). i flashed back the stock firmware (orange) and the phone works very well now except... again wifi. only this time... not only it does not connect to wifi but when i turn on the wifi that particular setting remains stuck everything else working just fine.

maybe someone can help

here's the logcat and the kernel log (don't know how to copy the complete kernel log :))

Something you could try (with root access) :

adb shell

$ su

# cp -f /persist/WCNSS_qcom_wlan_nv.bin /system/etc/firmware/wlan/prima/WCNSS_qcom_wlan_nv.bin

Looking at the update script when flashing firmware :

symlink("/persist/WCNSS_qcom_wlan_nv.bin", "/system/etc/firmware/wlan/prima/WCNSS_qcom_wlan_nv.bin");[/code]

but the /persist partition is never mounted so the file is not copied while flashing.

adb shell

$ su

# cp -f /persist/WCNSS_qcom_wlan_nv.bin /system/etc/firmware/wlan/prima/WCNSS_qcom_wlan_nv.bin

after i do this it says "sh: cp: not found"

(p.s. the phone is rooted)

i also think it has something to do with the stock rom itself... but i don't know.

Install busybox after booting with this boot.img ->

You can use this app to easily install busybox -> https://play.google.com/store/apps/details?id=stericson.busybox

now it says "cp: can't stat '/persist/WCNSS_qcom_wlan_nv.bin': No such file or directory"

Here is the file : WCNSS_qcom_wlan_nv.zip

Unzip it and push it to system/etc/firmware/wlan/prima (still use the boot.img from devidevinavil)

adb remount

adb push %folder where you unzip the file%\WCNSS_qcom_wlan_nv.bin /system/etc/firmware/wlan/prima

oooooh my god. problem solved. the wifi works now.

the problem with the inconsistency of the wifi persists (some networks work some not).

but my home wifi network works flawlessly.

vache you are great thank you very much.

question: does your wifi connect and work on any network? encrypted, with static/dynamic ip and all others?

p.s. i know why i had the problem with no wifi at all: the WCNSS_qcom_wlan_nv.bin file is missing from the update zip of the stock orgrod firmware file (i just checked and it's missing from system/etc/firmare/wlan/prima).

Hey. I am having the same problem, but I'm not able to solve it by pushing that bin fine.

The thing is, I've formatted all the partitions with cwm, including /persist :(

That was really stupid. Now, when trying to install the ROM from zip, it will fail to copy all the files. I'm looking for a firmware that's flashable through ADT or through a different method, because I need my partitions back.

Please guys help me. I can't use my phone like this.

Hello.

I have the same issue as bilbao1. Is there anything we can do about the /persist partition? (we are dumb, we know...)

[solved] Reflashed the correct stock and I'm back in business.
