It stats happen after 3 weeks of perfect work.
Asus RT-AC66U / 1.28.0000 MIPSR2-112 K26 USB AIO-64K
Total / Free Memory 249.63 MB / 237.50 MB (95.14%)
Total / Free NVRAM 64.00 KB / 32.80 KB (51.26%)
br0 = SSID 2Ghz + SSID 5Ghz + VLAN1
br1 = SSID 2Ghz + SSID 5Ghz + VLAN5
br2 = SSID 2Ghz + SSID 5Ghz + VLAN15
So I have 6 SSID and bridge them into 3 different VLAN
Suddenly 2,4 GHz stops authenticate users.
1. This is not an issue with Ethernet ports, cause Vlan bridging still working at 5Ghz.
2. I can see SSID - so this is not an issue with wireless module.
3. After power restart everything starts working again, for few hour…
4. logs shows nothing - the last what i see in the logs are ..
Sep 5 11:00:01 WiFi-AP08 syslog.info root: — MARK —
Sep 5 11:23:23 WiFi-AP08 auth.info login: root login on 'pts/0'
So , If I have SSID "Guest 2Ghz" & "Guest 5Ghz" (For some reason I need to have different name for 2 and 5 Ghz) and bridge it to Vlan 15, then suddenly, even if I see SSID on 2Ghz I cant use it (cant authenticate). Same time 5Ghz for same Vlan working perfectly.
Are there any helpful commands to detect problem?
The strangest fact is that i have two identical AP Asus RT-AC66U, that I use to enlarge/redundant coverage. But this issue starts happen only with one of them :(.
