I am always struggling to get a good throughput on my wireless. Is there a trade off choosing a multi mode 2"GHz b7g7n" vs “2 GHz only n” i.e. is the n connection slower when in multimode b7g7n?
PS. I found this
“Only 1 device ever transmits at any given moment on a WLAN. The more time your G client spends transmitting at its slow rate, the less time their will be for your N client to transmit at its faster rate. The N client still connects at whatever rate it would have, but its potential throughput will depend on how much air time the G client is using.”
I read this as - if a G device is connected, but idle, then i will not reduce speed on the n connection.
If you have all N clients then definitely switch of B & G support. I have sometimes used an old AP to provide legacy service so that N can run happily on the main AP.
The main advantage of 5 GHz is that fewer people are in the band and there is more space. It doesn’t always penetrate as well as 2.4 GHz though so you may need more APs - one the other hand frequency reuse is easier.
Thanks, that all makes sense. But I came across another points that I struglle with regarding the WDS and the n-standard.
on wiki i founs the following
“You MUST use WPA2 authentication with AES encryption only, or use no security at all if you wish to achieve N rates. Anything else is against the N spec and typically results in the client falling back to G rates.”
and at the same time i have in more places read that WDS does not work with WPA2. Does this all mean that it is not possible to have a properly working n-connection in WDS?
“You MUST use WPA2 authentication with AES encryption only, or use no security at all if you wish to achieve N rates. Anything else is against the N spec and typically results in the client falling back to G rates.”
This statement is ment for those users who wanted to use TKIP encryption. If you want to use N rate and good speed you should use AES.

If you want to interconnect two APs with WDS and use security, then you need to use dynami/static-mesh WDS modes.
