Re: Illegal channels. (Networking)
Depends on the local situation, the 2.4G band is a mess shared with video senders (usually marked in channels A-D), Microwave ovens, Bluetooth, and probably a few things I can't remember.

If your Wifi adapter software has a channel scan feature, or there are some other programs to do it, then check for other Wifi - with any moderately strong signals, best to be 4 or more channels clear (maybe 3 at a pinch), or on the same channel so it will sense and try to avoid collision.

The standard 1-11 plan is 1, 6, 11
The optimal 1-13 plan is 1, 5, 9, 13
The compromise 4 channel 1-11 plan is 1, 4, 7, 11 - 3 spacing not being completely clear.

If a channel just will not work, there's probably something else on it - the Wifi channel scan only picks up Wifi with broadcast SSID, so will not find any other sources of conflict.
