Wireless LAN WAP selection
« on: July 17, 2018, 05:28:59 AM »

If your device can hear a number of access points all broadcasting one or more SSIDs that you are able to log in to, how does your device pick which one to go for? I realise the answer might be system dependent but common examples would be helpful.

I am wondering if it is all based solely on signal strength, or on data rate, including the capacity doubling where you have bonded wide channels? In my case I am wondering about a choice between a 20MHz normal-width channel on 2.4GHz vs a 40MHz twin channel on 5 GHz.

I currently have a situation where there is a 40MHz 2.4GHz channel and a 40MHz 5GHz channel but am wondering it thing will be messed up if I were to reduce the 2.4GHz channel down to be 20MHz single width so I can fit more 2.4GHz ono-overlapping channels in. Would a strong narrow 2.4GHz channel attract all the stations even when they could have used a viable double-width 5GHz offering that is x dB weaker?

That applies to where the same SSID is in use. Where there are multiple SSIDs nothing more interesting than whichever they detect first or a list of them and whatever's at the top.
