Running Ubuntu 14.04 on a custom build. I have Encore wireless N300 PCI-E Adapter ( seen here ) The driver is available for download at this link as well. I am reading that a common fix for connection issues is to uninstall/reinstall the wireless driver. But before I jump the gun, I wonder if there is some other things I should look at first? Also, once downloaded, how do I install?

It only drops connection for a second, and then re connects. The problem is, I lose my VPN connection and it then reconnects clean. (WiFi drops regardless of vpn or open)

Note: I also have this posted for a few days in Ubuntuforums, but I've gotten no response yet.

Also went into Network Manager and locked in BSSID number in previously blank field. Still, I see the WiFi icon fluctuating. BSSID found through running:

cat /var/log/syslog | grep -e etwork -e wlan | tail -n20

Which gave me a message:

WLAN:0 WPA: GROUP
Rekeying completed with ( BSSID NUMBER)
[GTK=CCMP]

I've had this problem since I bought my wifi card with the same chipset. I'm pretty sure it's the chipset itself. I've googled for about 2 years and never found anything that works 100%. –  Chris Jul 21 at 17:04
