I have had a problem using Mobile Hotspot since I first got the Droid X three months ago. The 3G will go away at random while it's connected. The phone will be sitting in the same spot without anything being moved, and all of a sudden the 3G icon goes away on the phone and I have no internet service (i.e. I get the 'page cannot be found, check your connection' error). When I move it, it will come back but sometimes only for a minute. The icon will keep disappearing and reappearing at random. While this is going on, I have full signal strength (as far as what the phone shows in terms of bars). I only use my hotspot at work, so I thought it might have something to do with the building interferring with the 3G signal, but I tried setting the phone outside on a patio and the 3G still randomly disappears. I know it's not just the phone because I got water in it and got an insurance replacement and it does the same thing. I also have a coworker who has a Driod X and she has the same issue. I have another coworker who uses Verizon hotspot on her Thunderbolt (we do not live in an area with 4G yet), and she claims to have no issues with connectivity. The only other thing I can think of is if there is some application that both my coworker with the Droid X and I have that is interferring with the 3G signal. After reading other posts, I have made sure that the phone's WiFi is off. I also changed the channel in the security options, but I can't see how that or the security type could be the issue since the problem is receiving the 3G signal and not passing the signal onto the connected devices. Thanks for any suggestions or help anyone can offer.
