Hi all,
I just bought four 3800 AP. But they support only 2,4GHz. The speed of clients only 144Mbps.I checked AP and antena, all support both 2,4GHz and 5GHz
How to enable 5GHz ?
3800 model: AIR-AP3802E-S-K9
Four antennas: AIR-ANT2524DW-R

From your link :
"The Cisco Aironet AP‐3802E, AP‐3802P, and AP‐2802E contain a SMART antenna connector, which is connected directly to the flexible radio. Without a Smart antenna, the flexible radio must stay in 2.4GHz only mode" ==> I dont have smart antenna (dart). Does it mean I have to disable the flexible radio to use 5Ghz ? Please help how to disable, I try to figure out but no luck.

@Scott FellaNo 5GHz clients for AP 3800, it is very weird. In contrast, 3700s are serving both 2,4 & 5GHz well.

Hi @Scott Fella,
I tried to change as attached file but it seems for dual band 5GHz.
