Hi, I have a problem when I upgrade my MikroTik about 1 year ago I do not know what version (5.xx sure) but when I upgraded I lost a WLAN interface, said something similar when I upgraded, kernel error or something else .. . I tried the latest version 5.24, but there’s no way to recover the wlan interface … I am sure that the software problem, because everything worked well before the upgrade. I changed the WLAN miniPCI card and still no WLAN interface.

My MikroTik is a legal and Licenced LEVEL4 - MikroTik RouterBOARD 411-5NH.

Please help me? :frowning: :frowning: :frowning:
