You are absolutely correct. I will need to collect and provide more info.
BTW, the nexus is not yet rooted.
The phone is a rooted LG Optimus Q running android 2.3.4
The custom rom I am using is the arq 2.1
The tether is included in the rom and I believe it is from https://code.google
and is called "android-wifi-tether"
It works great on the phone. Asks for su permission and when I click it says it is tethering. I then went to my Windows 7 laptop and found it listed as AndroidTether with no encryption. The laptop connected with no difficulty
. Signal strength "excellent".
On the Nexus AndroidTether did not appear on the wifi list and so I added it. Still would not connect to AndroidTether and nexus says "not in range" which I think means it cannot detect it. Not sure why.
Here is another wifi problem that might provide a clue
This is a new Nexus 7 (2 days old). My home wlan is wpa2-psk protected with a long complicated password impossible to type out. So I connected using my router's wps. Immediately connected the nexus.
Then I left home with the nexus, and when I came home discovered the Nexus would not re-connect to my home wlan. I again had to resort to the wps which I really do not like. I assumed that for some reason nexus did not "remember" the password and perhaps that was because it was entered via wps.
Not likely, but just to check, I moved a text file containing the network password to the nexus, disconnected from the wlan and tried to manually reconnect using copy/paste to enter the password. Would not connect (yes it is the correct password and I've done this several times on other Windows devices).
So I think that for some reason there is a setting that is set wrong on the nexus. I am an old hand with computers but networks drive me crazy and I hate them.
Hope this sheds some light and thank you very much for taking the time to help.
