Up until this week, WI-FI tether has been working perferct. Im rooted on stock rom. I tried using it last night and after about 1 minute of using the tether app, i drop the signal on my laptop and Ipad. It works perfect until it drops signal. Im getting up to 13mbps on the speed test. Then after 1 minute passes it drops signal. I dont get it. Ive tried everything I can think of to get it working again. I havent changed anything on the phone, unless something was updated that i didnt know about. Any suggestions?
