In general, my wireless connection seems to be working fine but it keeps disconnecting and reconnecting when I start downloading files from deluge and Firefox.

I have tried most of the tweaks and workarounds I could find online in similar questions, but without any success so far. I am a very new Linux user so I would appreciate if somebody told me what I should post (perhaps from my log or something) in order to see if this problem can be solved.

I am running Ubuntu 15.04, and the command "type lshw -C network" gives me the following 

*-network

I thank you in advance for your help.

There are a lot of people on the low channels, especially channel 1. You are currently on channel 2.

Try changing your wifi router to use channel 11 for now.

Other problems may include your wireless router overheating or filling up with logs and having to reset. So, also check your wireless router logs immediately after the problem occurs so you can see if there is any helpful information like a recent reset or reboot.

Also, according to this post here, you might want to run the following command after suspending to reset wpa_supplicant:

systemctl restart wpa_supplicant

  • I will give it a go and let you know. Many thanks! – Chrilos Sep 12 '15 at 05:55
  • I changed the channel and it seems to be working fine now. Thank you for your help! – Chrilos Sep 12 '15 at 09:49
  • Nope, that did not work. As soon as I open youtube I lag and I although I am connected to the wifi the internet connection is not working momentarily. I get all this in the syslog, maybe this helps to understand paste.ubuntu.com/12366736/ – Chrilos Sep 12 '15 at 13:55
  • set your bssid to a static number and set your crda to the correct country in /etc/default/crda then restart network-manager or reboot – mchid Sep 12 '15 at 21:17
