I have a Dell 3520 with Win 8. It comes with a Dell 1704 802.11b/g/n wireless card. And it's a pain. I keep on losing the wireless connection (sometimes within a few minutes). It doesn't actually lose the connection (status shows connected but ping to the local GW fails). Disconnecting from the (wifi) network and re-connecting fixes the issue though sometimes only for a few minutes. I know problem is not with the Wifi network as other devices work just fine. Suggested solutions like disabling the BT or disabling power management option for this device has not fixed the issue.

Also could you please tell me what's wrong with your touchpad? It seems to have a mind of it's own. Sometimes it's too sensitive, and sometimes it's totally on the other end!!

Please help.
