What is a fat channel?

[Rubycon]

There's a selection (disabled) of FAT CHANNEL INTOLERANT. What exactly is this?

What's the context? If it's pre-draft non-standard 802.11N it refers to the channel width I believe. Need more info. a/b/g all have a fixed channel width, pre-draft non-standard N can be user configurable.

here it is

If I were to guess that means your client will not connect to wide channel access points. I'd leave it at default.

I turned it off and the connection seems more stable than before.

Unless there is something specific in a specific settings that the instructions are to change any of the Wireless hardware options it is better to leave them alone.

Unlike Mobos, Video cards, etc. where users got used to change parameters and Squeeze more from the hardware, changing the parameters on Network hardware without specific reason related to a specific Network is leading to trouble.

From http://www.intel.com/support/w.../wlan/sb/cs-025787.htm :

Fat Channel Intolerant

Communicates to surrounding networks that this WiFi adapter is not tolerant of 40MHz channels in the 2.4GHz band.
