B-U-M-P....really...75 views and nor responses. C'mon ppl, this is driving me crazy.

I have been syncing my Shine with my laptop via bluetooth recently, then using the Shine (and my data plan) as a modem for my computer. Everything has worked fine, except for one minor problem. While I am surfing the web, a notice on my phone will pop up saying that I lost the connection. My computer, on the other hand, still thinks I am connected...except for the obvious inability to use the web. This is becoming quite a problem, as I may have to reconnect my phone 5-6 times during 1 hour of internet usage. Anyone have any tips, or suggestions, as to what my be going on...and how to prevent it?
Thank You!
