D-link DIR-620 always rejects association
it was working somehow for almost 1 year and now again broken on my Arch linux Prestigio 133S laptop, a few weeks ago, after update, I've found 2 wlan interfaces instead of one and "no networks found" since then:
`~λ ip addr
....
10: wlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether 54:c9:ef:d7:cf:b7 brd ff:ff:ff:ff:ff:ff
11: wlp0s21f0u7i2: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000

full details will be later
oops ... it was my fault, rfkill soft blocked was yes, also local AP D-link DIR-620 always rejects association
any other WiFi-router works well but D-link DIR-620 always rejects association - how is it possible?
