Hello, Appreciate any help on this subject. recently got a new HP touch smart Desktop running windows 7. At random times, I lose connection while maintaining a full bar on my wireless signal. When I try to use windows network troubleshooter, it goes through the various steps and then says that it could not find the problem. I have changed routers with no help. reinstalled the wireless network adapters, again with no help. The ONLY way to get back on line is to restart the PC. HP helpdesk can't help. There suggestion is always to "recover" the system. Here are some specs; HD 1.5TB, 8 GB, Win7 64bit, Nividia GeForce 230Gt display adapter, Ralink wireless adapter, i7 CPU,. i am thinking of HW with an ethernet cable but am not sure if this will solve the problem. Thank you and hope someone can help me.
