    When looking at wifi speed the best case rule of thumb for work out though put is "device speed"/(number of clients + 1).
    The +1 is for the AP itself.

    I agree this can cause the issue. I have seen (via the AirPCap card) that the RSSI will be low when the AP is seen off channel (eg: lets say the AP is on 6, but the AirPCap is looking at 5 or 7). ...

    In this case, Insider is reporting the RSSI that your WiFi Card is seeing for the AP. ...

    Good call CJ_Man.
    300Mbps in the 2.4Ghz will use about half the channel space from memory, that is only 2 300Mbps N channels can fit in the 2.4Ghz.

    If there are three APs on channel 1, is there a channel with less APs on it ?
    RSSI is negative, thus -90 is a lower signal strength the -50, so -50 is the better of the two values.

    130/270N is...

    The noise looks like a device hunting (channel scanning). It reminds me of a cordless phone. It would be good to see the actual recording.

    I would put it on the one with the least traffic. This will be hard to know without looking at it with a sniffer or a wispy. As such, I would tend to go with channel 1 (with only one other SSID).
