Hello, It looks the problem on 2.4Ghz is different - I get packet loss sometimes but there are no disconnects, no wpa_supplicant entries in syslog at all. Now it runs great and is connected at 300mbps. I can not reproduce the packet loss on 2.4Ghz anymore. Does this help? How to update the regulatory database?
