I am tethering 4g on my Gs3. i am using the wifi tether app rooted. i can connect to my pc and speedtest gives me 25mbps down and about 13 up. but when i connect to my xbox my connection is extremely slow and i only have 3 bars. ITS THE SAME CONNECTION!!! i dont understand whats wrong. and also when i download files it can never go above 1mb. and its not the files because i have downloaded many and its the same story. my brother has the same connection with a nexus and gets 3mb on his files. can someone please explain why my tether is so slow and anything i can do to fix it. thanks so much in advance
