Wirless Connections Problem

On multiple computers, with Windows 7 Ultimate, I now have difficulties switching between wireless networks or connecting to airport/hotel networks. This was never a problem with Vista – could switch between networks easily and did not have problems when Windows 7 was first installed. My Windows 7 network consists of ATT wireless router/DSM modem and a Belkin wireless router/cable modem, IPAQ PC with Belkin USB wireless adapter, Acer Laptop with Aethros wireless adapter, Acer Netbook. Also have XP PC with Ethernet connection to the Belkin Router/Cable Modem. All drivers are up to date and the Belkin router is new. I also tried a new D-link router with no success at all. The Network and Sharing Center shows the available wireless networks. Whenever, I try to change networks, the non-preferred network comes up unknown and will not show internet connection. Running troubleshooter switches back to the preferred network. I can switch to the second network, by making it the preferred network and running home group and network trouble shooters. When I switch back to the original network, Windows 7 does not remember that it was a Home network. When traveling, it is a major production connecting to airport/hotel networks. With Vista, switching could be done in a few seconds. Any ideas?

CharlieRJ, welcome to the forum! A couple of questions here. Who did the configuration of all of these networks? Somehow or the other, you have a mess here, no offense at all, but there's a lot of configurations here. The wireless (cell) modems, can you uninstall, then reinstall them, and see what happens? It may help, I had two separate ones (Verizon & Cricket), and had no problems. This should be a straight forward connection with little (if any) configuration involved. Your home internet, have you called your ISP about this? It sounds like everything simply needs to be uninstalled (software and all) and reinstalled. You should have a manual on your router (your home one), it needs to be reset. That's my suggestion, is to start over. When my service was started (Time Warner), I wanted wireless, since my desktop has a wireless connection. Well, the original installer did something wrong, and within a week, I was having problems myself. Another technician came and reset everything the right way, and I've had no problems since. Redoing everything from scratch would be the best way to solve your problems. I hope this helps, CharlieRJ, and if you need further assistance, feel free to post back anytime. Best of luck to you, and I hope you get things back right again soon.
