Has anyone tested or know if there is any through put gains on an n ap if you still have legacy a or b clients. With the move from b to g there were no improvements as everything default to b, all clients needed to be upgrade to see any gains. I have not see anything either way in this regard. It would be nice if we could add in n clients with out having them all run at g rates.
I think you should still see gains. 802.11n is still OFDM, so it should be easier to switch between G/A and N, though it will certainly still have a performance hit compared to an N only AP.
Thanks, but was hoping someone might know a bit about how the compatibility works or has tested it. My thinking is along the lines of what you said but looking for some hard evidence to back up my thoughts on the matter.
RouterOS always supported different clients on AP with full speed advantage, so if you have b/g AP and you have both 802.11b and 802.11gclients, then those with 802.11b will get 11MBps max and those with 802.11g 54MBps air-raite.
Similar is with b/g/n mode where each client will get its advantages with newer protocol chosen.
Of course, take into account that using slower rates AP will take some time, so that time will not be available to faster clients and could result in slower speeds, but not brought back to 802.11b if you are connected with 802.11g client or 802.11n client.
while at it - you do not need to reboot the AP when change your settings
