When you connect via MAC telnet to the device -I meant without any other configuration - firewall or something else.I have an ip in the same subnet but the problem remains!!!!!!
Without a configuration you woun't be able to connect through IP telnet.. only MAC telnet.kristsd i will try to hard reset and just re-create user admin with my own password and no configuration at all and see what will happen.
It is very strange behaviour!!!!
You could try reducing tx-power and setting tx-power-mode=all-rates-fixedi will try what you suggest
but i expect stable connection with high speed 80 90 mbps
as i'm 2m far away from Wireless router
