Channel issue on 5g at 160ghz

[mstar]

hello all, anybody tell me how i can find interference on channels on asus routers? i tried looking gin wireless log but i am not sure how to spot this? for testing i set my 5g network on 160mhz.

The reason i ask is that my 5g network seems to have gone offline? i manually set it to channel 128 last week and only today its gone offline. Is this a natural thing thats happening it goes offline if interference detected?

I am trying to see where in logs it will say this only thing i saw is this:

Channel 100 A Band, RADAR Sensitive
Channel 104 A Band, RADAR Sensitive
Channel 108 A Band, RADAR Sensitive
Channel 112 A Band, RADAR Sensitive
Channel 116 A Band, RADAR Sensitive, Passive
Channel 120 A Band, RADAR Sensitive, Passive
Channel 124 A Band, RADAR Sensitive, Passive
Channel 128 A Band, RADAR Sensitive, Passive
Channel 132 A Band, RADAR Sensitive, Passive
Channel 136 A Band, RADAR Sensitive, Passive
Channel 140 A Band, RADAR Sensitive, Passive


Is the passive on channel 128 a reason?

If i set it to 20/40/80/160ghz and auto everything works and it sets to channel 100.

i am thinking the router to scanned for radar activity, and activity is detected, the AP is STAYYING off that channel for a period of time? and thats why my network went offline?

Never a good choice assign a DFS channel. Router detects RADAR and 5 GHz goes off line. Also better to do 20, 40, 80, 160 MHz and maybe auto channel. Forcing 160 MHz will frustrate you.

i put to Channel bandwidth 160 MHz and selected Enable 160 MHz AND put control channel to AUTO. however when i look on WIFI MAN it says this network is bandwidth is still 80mhz, is this becuase i have run out of space OR the app is wrong?

Assuming RADAR/DFS interference is an issue at your location, try these 5.0 max bandwidth and control channel settings (US) to not use DFS bands/channels:

80MHz bw, disable 160MHz; control ch 36-48,149-161

OR, let the router vary max bandwidth and control channel to coexist:

20/40/80MHz bw, disable 160MHz; ch Auto, exclude DFS bands/channels (36-48,52-64,100-144,149-165)

Using 5.0 DFS channels (required for 160MHz bandwidth) is a marginal proposition that your router DFS may prohibit at your location. The router Wireless Log lists current WLAN signals/bw/ch, 'noise', DFS status/action, and client/node connection details... cryptic, but there.
