I also have the dropping connections with my 2915abg. You can try switching the antenna from MAIN to AUX because tThat helped a bit for me. But i still experience the dropping connections, especially when i am in my room. There is just something weird with my room i think because i receive no cellular signal either. I have to walk out of my room to the livingroom to get connection.Also, when i go to my friend's house the speed tends to fluctuate a bit, but it has improved a lot as compared to before when i had the antenna on MAIN. I have also tried exchanging the card and it still experiences the same thing. But the only technical support i got from my manufacturer was to switch the antenna to AUX. I believe there is nothing else they could do. We really have to turn our hopes to intel. ANother solution for you is to buy a new card that works for your laptop. I ordered an Athero 5005 and hopefully it will arrive this week. I will let you know how it goes with my new card this week. You can leave me a message and i'll let you know how it goes.
