wifi not working correctly in kernel 4.2+

Hi everyone,

My wifi works well in kernel 4.1.x but it does not do like that in kernel 4.2.x. The computer can get a valid IP, but it can not browse any website, can not ping to anything ( include the default gateway ip, nothing shows when exec ping command ).

I use kernel 4.1.x now, but I want to know if there is a fix for this ? Thanks in advance.

Some details:

04:00.0 Network controller: Qualcomm Atheros AR928X Wireless Network Adapter (PCI-Express) (rev 01)
        Subsystem: Quanta Microsystems, Inc EM306 802.11bgn Wireless Half-size Mini PCIe Card [AR9283]
        Flags: bus master, fast devsel, latency 0, IRQ 17
        Memory at 94600000 (64-bit, non-prefetchable) [size=64K]
        Capabilities: <access denied>
        Kernel driver in use: ath9k
        Kernel modules: ath9k

Re: wifi not working correctly in kernel 4.2+

hello, i also experienced similar problems with 4.2.5-1, i can connect but i am only getting ~3MBps download when on ethernet i get ~60Mbps. looking into downgrading kernel but havent done so yet, other distros give me much better speed with older kernel. i have same hardware as you.  will report back when i test out old kernel, have to figure out how to do so first!

Re: wifi not working correctly in kernel 4.2+

Which network manager are you using ? Have you tried another one ?
Can you ping 127.0.0.1 ?

Have a look to journalctl see what's logged during connecting.
