Hello, I'm new to Linux (although I have some experience in running it in VMs) and decided to dualboot my laptop (HP Elitebook 8570w, Win8-x64) with Linux Mint 17 x64. Everything seems to be working fine except the wifi. I can see my network and connect to it just fine, but after some time (could be 5 minutes or 1 hour) the wifi will suddenly stop working (as in I can't ping anything, not even my router). The odd thing is that network-manager will say I'm still connected to the network. Manually disconnecting and reconnecting will make the wifi work fine again (for some time until the same thing happens again). The issue is only present when I use Mint (Windows never drops the connection) which makes me believe it's either a driver or configuration problem, but I have no idea how to fix or diagnose either of them.
Here is my mintWifi output:

I'd greatly appreciate any help. As much as I like using Mint having to constantly deal with these wifi issues is beyond frustrating. Perhaps I'll try a different distro, but I'd prefer to get Mint working instead.
Thank you for reading.

Thank you for reading.
Do you have mintwifi results from when it doesn't work?
Better yet, we can install pastebin and run a script created by some very smart people on ubuntuforums
Code: Select all
wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script
The script will ask if you want to upload, if you press y and then enter, you will see a URL in terminal that you can copy with the mouse and paste into your next post. And if you happen to lose your access to internet however long after you can run a new script with
and choose n when asked about uploading. Wait until you have a connection again and
and paste the url into a new post and tell us script from non-working wifi

Here is the wireless_script output for the working wifi
http://pastebin.com/kxk6f7C6
When I lost connection and tried to run mintWifi something odd happened. I had no connection at all (couldn't load pages/ping anything). The script hang on the line '* V. querying DHCP...' for about a minute before suddenly finishing. At the same moment it finished my connection was suddenly working again. The output is identical to when it is working (probably as the connection came back for whatever reason while running the script). Perhaps this was just a fluke and I'll continue to stress my network to try and get it to drop again so I can try to run the scrips when it isn't working (ironically when I want the network to stop working so I can run the scripts it seems more stable than ever).

After having pretty much an entire day of working wifi (probably downloaded around 15gb of data without it breaking) the internet finally broke again.
Here is the bottom section of the syslog (I'm not sure when exactly the connection dropped but it was somewhere during this time).

Can you change security/encryption to WPA2-AES only?

I've set the security to WPA-2 AES (had to reconnect after, which isn't that surprising) which seems to be working. I'll report back when I start having issues again (or if this fixes it).
Thanks for the help so far.
Edit: Connection just stopped working again.
Here is a syslog (probably dropped between 13:38 and 13:40)

Log of the wireless_script output when the connection died.
My router (actually from my neighbors, but they let me use the connection) transmits at both 2.4Gz and 5Gz under the same SSID. I've now set the BSSID (which I hadn't done before). Could that cause some kind of conflict or shouldn't it matter at all? I've also set the 2.4Gz connection to 20/40Mhz as opposed to 20 only.
Would there be any recommended settings for Linux clients?
Also could the problem simply be the case that the signals sometimes takes a dip which causes the connection to stop working, but network-manager simply fails to detect this? Perhaps Windows somehow manages to receive better to a point where it does not fail with a weaker signal as opposed to Mint.
I have no idea what the issue is here and I'd appreciate any help I can get.

The 20/40 should be fine, but we could try enabling agg TX, if nothing else you might see a speed increase
Code: Select all
echo "11n_disable=8" | sudo tee -a /etc/modprobe.d/iwlwifi.conf
reboot
If that doesn't make any improvement on the disconnects, I would disable TLP and see what happens
