My friend has an older Dell desktop, a new Dell laptop with the TrueMobil wireless network card and a Dell wireless router. The desktop is hardwired so no problems there. The laptop seems to always indictate that its signal strength from the router is excellent. However, actually connecting to the internet is 50-50. Can't figure out how to be able to consistently stay online. I'm not that familiar with this hardware so maybe someone can shed some light on this issue. Thanks.
