Hello, Ultima ROM 8.1 is based on v4.1.2 of Android and with that version I get loads of WiFi issues. It will intermittently connect to wireless networks but other times it doesn't connect and sticks on authenticating. Now these WiFi issues would also happen on stock 4.1.2 so I don't think it's because of the ROM. 4.1.1 worked flawless on WiFi. I've tried to use a static ip but that doesn't work either. Also that really isn't a solution as im in and out of different offices all day.
