Could someone explain causes of possible wide CCQ variation? I’ve the following figures:
Mode: station
Freq: 2472 (only-G)
TX/RX strength: -64/-63
Noise floor: -97dB
Signal to noise: 35dB
Tx/Rx CCQ: 11/84%
So the AP is receiving the station with far less clarity than the station is receiving the AP?
I do have another client on the same frequency almost directly in line between the AP and this one but at half the distance. However both clients and the AP are Mikrotik boards and polling is turned on - it’s ticked on at the AP and ticked but greyed out on the clients. Nstream is turned off. CSMA is not disabled.
Probably one radio sees a bunch of noise, the other radio doesn’t. Did you run spectrum scans from each end and plan your frequency use based on the results?
I didn’t mean with a spectrum analyzer. I meant with Winbox and Frequency Usage test on the Wireless Interface menu. And BTW, there are some very cost effective spectrum analyzers out there from Wi-Spy and Ubiquiti. Even small ISPs can now afford them.
If the 80/84% CCQ stands, then you are free and clear. Either the offender moved to a different frequency because you were creating too much noise for them, or your test sample was just too small and once you sent some traffic over the link, the average went up.
If I run a frequency usage scan on the wireless interface on which I’m connected to the Routerboard will I cut myself off? I’ve done that before with a site scan, and had to ring the subscriber to ask them to reboot the router!
One of the advantages of being a remote, rural network in a mountainous region is that there isn’t a lot of competition for frequencies.
