You have been subscribed to a public bug:

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.
