[SOLVED] Unable to connect to WiFi from Asus K501UW

Hi all,
    I have installed Arch on my new Asus K501UW. Except for the wifi, everything works fine. The WiFi card is Intel 7265. The NetworkManager correctly shows the list of APs but when I try to connect to any AP, it quickly errors out. The dmesg output is:

iwlwifi 0000:03:00.0: L1 Enabled - LTR Enabled
iwlwifi 0000:03:00.0: L1 Enabled - LTR Enabled
iwlwifi 0000:03:00.0: L1 Enabled - LTR Enabled
iwlwifi 0000:03:00.0: L1 Enabled - LTR Enabled
IPv6: ADDRCONF(NETDEV_UP): wlp3s0: link is not ready

The strange thing is that the same error happens even when I connect a USB wifi adapter (the same adapter works fine with my old laptop running Arch). The dmesg is the same there also.

I saw a similar post in the forums where the solution was to give an option to the asus_nb_wmi module. I tried

options asus_nb_wmi wapf=n

for n = 0, 1, 2, 4, to no avail.

Also, NetworkManager is the only network manager running. netctl or dhcpcd are not installed.

You don't have dhcpcd installed?

What are the output of ip link and of iw list
?

ip link:

I uninstalled dhcpcd to make sure that it was not due to it that NetworkManager is misbehaving.

Re: [SOLVED] Unable to connect to WiFi from Asus K501UW

Finally got it! From this answer. I edited the WiFi connections to ignore IPv6 and voila it connected!
Again experimenting, it seems it is also necessary to have

options asus_nb_wmi wapf=1

in a modprobe conf.
