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

 

The machine has been running on an external wifi card for a while, and
it's working fine.   I've swapped out the RTL8188ee card for an Atheros
(mini pci) and this should let us see if it's really RTL8188ee to blame
or not (or a antenna, location issue).

I did complete a series of wireshark tests and determined packets are only lost on the receive side.   
I did ping -i 0.05 -c 1000 -s 512 to and from the machine in question, (to a machine <1 foot away).  Over 4 runs (2 from, 2 to), 2-9 packets were lost, ALL when going -> RTL8188ee.  No packets were ever lost sending from RTL8188ee to other machine.

Title:
   rtl8188ee wireless driver high packet loss

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  This is a toshiba c55d laptop. I've seen this issue since trusty, very
  bad packet loss,varrying in ping from 10%-45% to  Verizon MI424WR-
  GEN3I AP 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.

  Already tried mainline (3.18.0) with no noticeable improvement.

  I will be trying the Realtek (from their website) - didn't work, not for this kernel.
  https://github.com/FreedomBen/rtl8188ce-linux-driver - didn't help.
