Ubuntu 11.10 - Internet Connection
 

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?

More information is need for assistance. This could be a driver issue and without specifics of the Wireless LAN card and the drivers in use, it might be difficult to assist. This is especially the case with proprietary cards such as Broadcom 4313. To get this information, post a dump of the commands,

to get the wireless interface card details

And
to get the loaded kernel modules.

Hello!
I have a very similar problem. I have an Acer Aspire 4739-6483 (notebook).
I have just installed ubuntu 11.10 on it. At first, the wireless connection was very good everywhere in my place. But after only 10 minutes, the signal became very weak everywhere except near the router. Even after reboot, it's the same thing: the signal is strong at first but after a few minutes it becomes really weak and I have to be in the same room as the router to stay connected. I don't understand.

(I have another computer, a desktop, with ubuntu 11.10 insalled and I don't have that problem with the connection which is also wireless...)

This is what I get with '' lspci | grep -i 'wireless' :

02:00.0 Network controller: Atheros Communications Inc. AR9485 Wireless Network Adapter (rev 01)


And this is what I get with '' lsmod '':

Please help me if you can!
Thanks in advance!

Hi BernBern, my bet would be to find out which Linux drivers are best for your wireless card. I suspect, this is not guaranteed the case, the mac80211 might have something to do with it. I had an issue with the same at some point which I resolved by blacklisting the driver and installing proprietary drivers for my Broadcom card at that point. I don't like proprietary drivers, or whatever else people will call them but, if that's all that works, go for it.

Thanks for the advice ochienged!
But I'm a complete noob and I don't know how to do that!
