WiFi Connection problems with a "Qualcomm Atheros AR9485 Wireless Network Adapter"

[jeremy31]

This should work for the TP Link

sudo apt-get install linux-headers-$(uname -r) git build-essential
git clone https://github.com/lwfinger/rtl8188eu.git
cd rtl8188eu
make
sudo make install
sudo modprobe 8188eu

Thanks for that potential solution. Been trying it out for an hour or so, the loss of connection appears to be less frequent, but it's still happening from time to time unfortunately - I still have to re-enable WiFi for the connection to come back.

When the loss of internet occurs, are there any diagnostic commands I can run to check to see exactly where the problem is?

[jeremy31]

You could check

dmesg | tail

or

cat /var/log/syslog | tail

It might be worth checking the regulatory setting

iw reg get

If it matches your country you should be ok, if it doesn't check http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2 to find your two letter country code and set it with

sudo if reg set US

Replace US with your own if you aren't in the US

Thanks for the tips, I'll run these soon. Earlier today I bought another new wireless adapter just because I thought it would be a quicker and simpler solution to all of this, as I'm trying to get this fixed asap - this is my work laptop. Unfortunately the issues persist even with another adapter, so in total, that is now 3 network adapters that are constantly disconnecting over the wireless.

I think there has to be something very wrong going on here that's not adapter specific. Any chance there could be some kind of conflicts between the drivers or something like that? It's really weird.

You could run the wireless script from the sticky post "Before posting in Networking and Wireless" and post the results

Hey, Im still having issues with networking capabilities. Ive completely reinstalled Ubuntu, removed Ubuntu 14 and installed 15 on a brand new format.

The 2 network adapters that Im using cant even connect to any wireless router now. Heres the result of the network diagnostic script, would massively appreciate any advice.

Can you change the channel to 4, 7 or 8 and set the encryption to WPA2 only?

Hey again, I'm done with trying other wireless adapters, the connection is so intermittent with both the TP-Link and the Netgear when connected to any router. The best connection I have is with the Atheros, it's always a stable connection and fast, but it still randomly powers off, and there's no way of getting a connection again until the computer is rebooted. Here's the output from Dmesg just now after it happened:

Will massively appreciate any help!

I wonder if there's a firmware update available for your router?
This was suggested here:
https://bbs.archlinux.org/viewtopic.php?id=137643

Our router updates automatically so yours may be the same.
However if it is not, it might be worth doing.

Thanks for your help, but this really isn't router specific. I've been using a lot of different routers lately, and the problem exists with all of them. I've tried disabling power saving for the adapter, the nocrypt solution, and I even tried out a fresh installation on Ubuntu 15 the other week. Nothing works.

Anything else you suggest that I could try? I'm out of ideas, and have been researching this problem on the internet for weeks.

Also, do you have any suggestions for a reliable usb network adapter that's guaranteed to work with Linux/Ubuntu?

Cheers.
