I have recently installed Ubuntu 15.04 after having been forced to use windows for about a year. Unfortunately my laptop is having some pretty severe wifi issues since the switch. I suspect it is a driver issue of some sort, but I am certainly not an expert when it comes to anything of this nature.

I connect fine to the network, however my speeds are about 1/3 to 1/2 what they were on windows and the connection has a huge amount of jitter and packet loss type problems. An example would be that I cannot use any video streaming type of applications since it will go from playing HD video without problems to suddenly buffering every 5 seconds on SD.

I have included the output from the "wireless_script" that seems to be popular on here. Any help would be greatly appreciated! This is driving me crazy

Edit: the script output was too large for this post, so here is the file

First, check the settings in the router. WPA2-AES is preferred; not any WPA and WPA2 mixed mode and certainly not TKIP. I have better luck with a fixed channel, either 1, 6 or 11, rather than automatic channel selection. Also, be certain the router is not set to use N speeds only; auto B, G and N is preferred. After making these changes, reboot the router.

Next, I'd set IPv6 to Ignore in Network Manager: http://docs.fedoraproject.org/en-US/Fedora/18/html/Installation_Guide/images/netconfig/network-connections-ipv6-ignore.png This example is for ethernet, but you want wireless.

If these changes are ineffective, I will edit my answer to add additional steps.

  • That seems to have done the trick so far! I'll let you know if there are any other problems, but it is already working MUCH better thanks! Apr 29, 2015 at 23:36
