Fresh 14.04 install on a Packard Bell Notebook.
WiFi device:
02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8192SE Wireless LAN Controller (rev 10)
rtl8192se kernel module
If connecting to my home WiFi, it shows as connected, but there is no connectivity. I can't ping anything, not even the access point itself, althought DHCP settings are retrieved correctly.
iwconfig reports a rate stuck at 1Mb/s, although link quality is 70/70 and Signal level -28dBm.
If I set the rate to auto with "iwconfig wlan0 rate auto", it switches to 54 Mb/s (max the AP supports) and everything seems to work fine (I used it for few hours now, downloaded few 100 MB, mostly Ubuntu packages).
When connecting to an Android Hotspot, the problem doesn't occur, thus it seems to be AP dependent.
Difference in dmesg between connecting to the "bad" and the "good" AP:
When connecting to the bad one, it additionally shows this 2 lines:
[10961.059621] rtl8192se 0000:02:00.0 wlan0: disabling HT as WMM/QoS is not supported by the AP
[10961.059626] rtl8192se 0000:02:00.0 wlan0: disabling VHT as WMM/QoS is not supported by the AP
Don't know if that's related.
I've been connected to this AP with a lot of devices (mainly mobile) without any issues.
The AP is a Linksys WRT54GL with Tomato 1.28 firmware.
