Galaxy 5GHz HiBand (>5.7GHz) not working
I found out this is also a problem with my Note 10.1.
If I set the 5GHz band to be in the 5.4GHz channels, the Note 10.1 can see the 5GHz WiFi, but if I set it to channels above 5.7GHz or Auto, it will not see the 5GHz WiFi.
Anyone have some experience with this?[/QUOTE]
The issue is with a configuration file... here is the fix for the Tab 10.1... it should be similar for the Note.
Galaxy Tab 10.1 5GHz HiBand Wifi Fix
There is an issue with the Galaxy Tab 10.1 (and apparently many other Galaxies) only working on the lower 5GHz channels because it is configured for the UK
You need to update the Country Code (ccode) in nvram_net.txt
You need root to do this.
In /system/etc/wifi there are two files:
nvram_net.txt and nvram_net.txt.us
The installed one is for Great Britain, and the other one (.us) is for the United States.
Rename nvram_net.txt to nvram_net.txt.gb and rename nvram_net.txt.us to nvram_net.txt
Or make the following changes to the current configuration file:
Change "ccode=GB" to "ccode=US" and add immediately after "regrev=5".
The files might be slightly different, but look for the ccode=GB line and change it to =US or =ALL
I haven't fixed my new Note yest, but if I run into any difficulties I will repost
