Hi to all ! i've a problem with my network controller, sometimes wireless drop connection or with public wifi is difficult to authenticate with the AP .
My Network controller is :
02:00.0 Network controller: Ralink corp. RT5390 Wireless 802.11n 1T/1R PCIe
my latest dmesg :
[ 1218.867712] rt2800pci 0000:02:00.0 wlp2s0: disabling HT as WMM/QoS is not supported by the AP
[ 1218.867718] rt2800pci 0000:02:00.0 wlp2s0: disabling VHT as WMM/QoS is not supported by the AP
[ 1218.870770] wlp2s0: associate with xx:xx:xx:xx:xx:xx (try 1/3)
[ 1218.873111] wlp2s0: RX AssocResp from xx:xx:xx:xx:xx:xx (capab=0x411 status=0 aid=1)
[ 1218.873607] wlp2s0: associated
[ 1218.873653] IPv6: ADDRCONF(NETDEV_CHANGE): wlp2s0: link becomes ready
i use dhcpcd and wicd ( with driver wext )
I have the same issue with network manager on public wifi, on sites like libraries it is impossible to connect. I was using wicd, i changed to network manager but the issue is still there and i don't know what's the problem.
My network controler is:
03:00.0 Network controller: Atheros Communications Inc. AR9287 Wireless Network Adapter (PCI-Express) (rev 01)
Sorry for my english
