I'm running the latest Ubuntu 14.04.3, and my issue today is that my Wifi connection sometimes becomes really slow, and eventually disconnects. I tried googling around to see if I can get any good answers, but nothing fixed my issue. I found a thread that used a diagnostic tool (wireless-info on github), which might help you guys figure out if there's anything wrong with my current system/drivers. This is what the diagnostic tool found. http://paste.ubuntu.com/12041942/ Is there anything I can do about this? I'd love to get this issue fixed. Thanks!

There are no less than eleven SSIDs in range with the same name. In your message log, we see your wireless device roaming from among them.

I suggest you ask your wireless to bind to your access point. Right-click the Network Manager icon, select Edit Connections. Fill in the MAC address for your access point; find it with:

sudo iwlist wlan0 scan

For example:

Cell 05 - Address: 00:13:19:F2:2E:D0
                Channel:6
                Frequency:2.437 GHz (Channel 6)
                Quality=66/70  Signal level=-88 dBm  
                Encryption key:on
                ESSID:"UCInet Mobile Access"

Use the address (MAC address) you found for the strongest access point to place in BSSID in Network Manager:

Save and close.

You could maybe try this from the terminal:

   rfkill list up
   lspci wlan0
   rfkill list up

and then this:

   sudo -i
   gedit /etc/networkmanager/ifupdown/ifupdown.conf

and then write in this line at the bottom:

wirde properties=true

and it might work fine this way.

    Do you just type random commands? They will do no harm except creating a useless file in /etc. And will do no good. – Pilot6 Aug 11 '15 at 17:13
