Recently it started acting a little flaky. any streaming videos would stop after the first few seconds, emerge sync would either take forever to get started or stop halfway, and downloading any larger files would fail. I recently renewed my contract and got a new phone (blackjack ii), thinking it was the old phone as it would get very hot. The issue persists and has gotten worse to the point that it is unusable. Now, browsing/email still works fine. Streaming videos and it seems any sustained download fails. If I attempt to start an emerge sync it will seem to halt ALL internet traffic, same thing with other high traffic things - ALL internet traffic halts. and I either have to wait a few minutes or reboot the phone and connect all over again to get it working again. I have noticed that when this all stops working, I can still ping the phones ip address just fine, I just can't get anywhere past it. So it seems the bluetooth connection between the phone and computer still works just fine. I then started thinking that it may be some blocking technique at&t has implemented to stop people from torrenting/downloading lots of stuff on their 3g network and am about to cancel the internet plan as it is unusable. Then a coworker of mine told me he has no problems with tethering at all. Youtube works, downloading works, and he can even torrent. So I decided to do something I hardly ever do - boot into windows XP and connect through my phone the same exact way. And guess what.....IT WORKS FINE! Can anyone offer any explaination? I'll have to try my wifes ubuntu box and see if it has the same issues as mine. It just seems very odd that it works fine in windows but not in linux, and that in linux when internet stops working I can still ping my phone. Is it possible that at&t has some way to see if I am using a non-windows OS and then screw up the connection? Or could it be a bluetooth PAN issue in linux? ------=_Part_32398_10034688.1218410633889 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Content-Disposition: inline
