2.4Ghz speed?

I deployed 3 x AP11 and 3 x AP15 in a network. Using a scanner, I can see my SSIDs with speeds of 1.733Gbps and 866Mbps on the 5 Ghz band expected. On the 2.4GHz band, I only see 144Mbps. Shouldn't I see 300Mbps?

@axthemax The 2.4GHz band is using 20Mhz so not to interfere with the limited channels. That is the reason you are seeing speeds of 144Mbps.

Re: 2.4Ghz speed?

Does this mean, either 20Mhz or 40Mhz are assigned dynamically or is it always 20Mhz? The data sheet says: "2.4 GHz 802.11n 2x2 MIMO for up to 300 Mbps wireless data rate (Wi-Fi 4)". Up to 300 Mbps would require 40Mhz, no?

Hi @Charmacas and @axthemax ,

Yes, AP can select 20/40MHz and hence work upto 300Mbps. If it is currently on 40MHz and detects activity/noise in the background, and then it changes to 20Mhz channels

Well, I have 7 APs now and some are positioned in a basement with no noise at all and I never seen 40Mhz channels on the 2.4GHz band....

@axthemax There will be a software release that will give you this capability.
