[FIX] Broken 5ghz Wi-Fi on OLYFR_U4_1.5.2

[Da_G]

So, in a nutshell, Moto decided to update the Wi-Fi firmware on the feb 22 leaked .sbf and broke it.

Attached are the 2 firmware files from stock ROM to fix it (there are 3 in total, but only 2 changed)

Turn off Wi-Fi, replace the same files in /system/etc/firmware/wifi using adb or Root Explorer, turn Wi-Fi back on, et voila, working 5GHz.

Working hard at more hacks

so this is for better wifi? and if i have the adeo rom will this work?

The Atrix features a dual-band Wi-Fi radio capable of operating at both 2.4GHz and 5GHz. 5GHz is typically used in high-interference areas like my city which provides free Wi-Fi access city-wide. I can't get any range at all on 2.4GHz.

The leaked February 22 .sbf introduced a new Wi-Fi firmware which (probably not purposefully) disables 5GHz support. I've supplied the stock Atrix Wi-Fi firmware in which 5GHz support works correctly.

This won't help you at all if you don't have a router that supports 5GHz But you never know when you might get an opportunity to hop on a network that does, and your Atrix won't see it running the Feb 22 firmware.

No leaked SBF kills 5ghz wifi. So you need to push the old files back on to get 5ghz back.

It's the stock wifi firmware. The leaked SBF had a problem with 5Ghz wifi.

Another great hack... thanks much!

.sbf: Summation Briefcase File

File that allows you to restore phone to out of box condition if something goes wrong i.e. bricked phone.

Hey what permissions should be on the files in the /system/etc/firmware/wifi directory?
cuz i only have this:
-rw-r--r-- root root 264070 2011-02-22 18:38 sdio-ag-cdc-full1
1n-minioctl-roml-pno-wme-aoe-pktfilter-keepalive.bin
if it might be connected to my problem once i put in the workign sim, which would be rather unlogical but still ...?

@crnkoj:

I don't think it's the problem, but here are the proper permissions as follows:

cd /system/etc/firmware/wifi
# ls -l -a
ls -l -a
-rw-r--r-- root     root                 1747 2011-02-22 09:38 nvram.txt

[crnkoj]

aha, thanks, it seems to be the same on mine. hope you got the pds dump on the mail

 

[michael0619]

thk you for share~

 

[txtsd]

I made a thread in the General subforum a few days ago about my phone not being able to detect my 5GHz network. Hopefully this will fix it.

EDIT: I copied the files over, but my phone still doesn't detect my 5GHz n-network.

 

[fRenZy-_-]

So how do we know if we updated it to this? and is this the cause on why my phone's connectivity to wifi sometimes disappear even though my router is right next to me? im running adeo v0.1

 

[Sogarth]

... I'm confused. I'm on 1.5.2 (after a soft brick, woo!) and I can connect to my 5 GHz network just fine...?

5 GHz, 40MHz band, WPA2/AES/802.1x

Is your network n-ONLY, or mixed?

EDIT: nvm stupid question.

 

[bbtheory]

Thanks to the OP... copied the two files over with root explorer and now have 5ghz wireless...

 

[resin99]

Is this also broken on 1.2.6?

 

[cataclysmicvoid]

5Ghz isn't working on my Atrix with 1.2.6 SBF flash. I haven't tried this fix, but I am surprised that it isn't working on the stock SBF...



Edit: Reflashed SBF and when it said manually power up phone I restarted (twice!) the phone until it said complete (even though the phone booted automatically). Now it is working.
