Title:
  rtl8188ee wireless driver unusable: 25-30% packet loss. 13.10 Saucy

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I'm seeing a consistent packet loss problem with the rtl8188ee Realtek
  wireless driver.  Long sequences of pings to the access point IP show
  25-30% packet loss.  Downloads get 'stuck', pages don't load, it's
  generally unusable.

  I've tried the following kernels:

  /boot/initrd.img-3.11.0-12-generic  /boot/initrd.img-3.12.3-031203-generic
  /boot/initrd.img-3.11.0-14-generic  /boot/initrd.img-3.13.0-031300rc3-generic

  all with the same result.  Packet capture shows lots of dup ACKs, some
  retransmits.

  I suspected 802.11n might be the culprit, but I've disabled it at the
  AP, and the driver seems to respect that judging by these log lines:

  Dec  7 21:50:52 congo kernel: [13812.218008] rtl8188ee 0000:01:00.0 wlan0: disabling HT as WMM/QoS is not supported by the 
  AP
  Dec  7 21:50:52 congo kernel: [13812.218011] rtl8188ee 0000:01:00.0 wlan0: disabling VHT as WMM/QoS is not supported by the
   AP

  Other than those lines there isn't anything noteworthy in syslog.

  Very interested in getting this fixed, please let me know how I can
  help debug.
