How long does your connection last when tethered

[Ka_Dargo]

Hi all,
first post if you dont count my introduction.
I have been trying to tether my Mogul and it does connect but usually doesnt last long. I have had it connected for up to 45 minutes but will suddenly disconnect, if I have something like streaming video it will disconnect after just a couple minutes. I have scots rom (i think) and have searched most of these forums and checked all of the usual settings. Like I said it connects but doesnt stay connected. If you need more info let me know.
Thanks in advance.
