[Bug 1401741] Re: rtl8188ee wireless driver high packet loss

 

The FreedomBen driver doesn't appear to help.
Realtek's drivers on their site don't work on kernels >3.9... so I didn't test them.

New testing right next to the router, packet loss ~8%, latency average
>8ms,  tops in the 100+ range

Changing to legacy b/g only - still packet loss.
 -> channel 1 - no effect, still packet loss.
 -> channel 5 - tests show no packet loss!
 -> channel 6 - tests show no packet loss!
 -> channel 11 - no, effect, still packet loss

b/g/n retesting:
 -> channel 1 - still packet loss
 -> channel 6 - no packet loss (sometimes groups of 100 0-3 packets lost).. much better than other channels. 
 -> channel 11 - still packet loss

If you have the same issue, try using Channel 6.

Title:
   rtl8188ee wireless driver high packet loss

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I've seen this issue since trusty, very bad packet loss,varrying in
  ping from 10%-45% to the gatewway.     This is a toshiba c55d laptop.

  Already tried mainline (3.18.0) with no noticable improvement.

  Previously reported here:
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1258870

  AP is a MI424WR-GEN3I from Verizon with WPA2 running in  Compatibility Mode(802.11b/g/n)
  No other devices on network have ever had this issue, in fact any loss of ICMP packets almost never occurs on other devices from same location.

  I will be trying the Realtek (from their website) and
  https://github.com/FreedomBen/rtl8188ce-linux-driver next.   Any other
  ideas/suggestions welcome.
