Radio 1 is on a/n mode on the 5 GHz band and Radio 2 is on g/n mode on 2.4 GHz.<BR /> I read somewhere that g is backwards compatible with b, so does that mean the performance drops to 11Mbps if a b device connects to g?<BR /> <BR /> Wed, 11 Feb 2015 04:43:00 GMT https://community.extremenetworks.com/t5/extremewireless-wing/how-can-i-unconfigure-the-802-11b-protocol-at-all-my-4610-aps/m-p/60477#M5374 Laura4 2015-02-11T04:43:00Z https://community.extremenetworks.com/t5/extremewireless-wing/how-can-i-unconfigure-the-802-11b-protocol-at-all-my-4610-aps/m-p/60478#M5375 its only backwards compatible if you have b turned on.
