I have a lenovo T61 laptop that keeps dropping the wireless connection. I have searched the web and tried different things like using a different wireless card than the internal one and I still have the problem. My Dlink DI-624 wireless router is in the same room as my laptop about 8 feet from it. When it works the signal is excellent. I have tried changing the power management scheme to max performance from balanced or max battery. This did not help. What else can I try? I called lenovo and they did not help. Sometimes it drops 3 or 4 times a day sometimes it goes a few days before dropping.
