I have a Gateway NV53A Notebook, dual boot with Windows 7 & Ubuntu 11.10.

I have installed the latest Ubuntu updates.

My primary Internet connection method is:
802.11n Wireless Network with cable ISP

The wireless network runs fine under Windows 7, but it runs erratically under Ubuntu 11.10 with frequent drop outs that require a reboot.

My backup Internet connection is:
Verizon 3G Personal Hotspot

The Verizon connection runs fine under both Windows 7 & Ubuntu 11.10.

Question: How can I get a reliable Internet connection via the 802.11n Wireless Network under Ubuntu 11.10?
