The usual solutions to this are: 1) Try 5GHz if your clients support it (even if only some do, it can be worth doing to reduce congestion in 2.4GHz). 2) Add more APs closer to the users - I have one CBD site where we ended up with 3 APs covering an office space of ~350-400sqm just to get over the noise -----Original Message----- From: Public [mailto:public-bounces@talk.mikrotik.com.au] On Behalf Of Karl Auer Sent: Monday, 22 December 2014 10:34 PM To: MikroTik Public Subject: [MT-AU Public] wifi interference - solutions? Dunno if this list accepts attachments, but if it does, a scan and a spectral-scan are attached. The scan shows senders on 2412, 2417, 2427, 2437, 2457 and 2462. The spectral-scan shows - well actually I'm not sure what it shows :-) What's the best way for me to get decent wifi for people associating with this router? At the moment, it's pretty patchy. I was thinking maybe change to a 10MHz channel width and aim for one of the channels not seen, like 2452, but I don't really know what I'm talking about so was hoping for a clue from someone more, er, clueful.
