Hi villain36, see the post i referred to above.
I also do not have the uninstall option for Wifi access points in Titanium Backup. I have gone into wifi settings and told it to forget the network. I will then when i return home try and connect to it again.
Have already tried this but is worth another go before trying something more drastic.
Last night i tried rebooting the router, incase it was something on there preventing it, but this did not help.
Turned the router off this morning and will turn it back on when i get home, as this may help.
Next step if those don't work are to perform a factory reset and clear cache and then see if i can reconnect to wifi once rebooted and when nothing else has been restored/added.
Finally if not i may return to the stock RUU for the remainder of the week until i can play further with it at the weekend. I also want to S-OFF and its advised to have stock rom on anway so this should make that process easier.
If you fix it let me know. Cheers, good luck.
