I've setup two APs dap-2553 to run one on 2.4 (b/g/n mode) band and another on 5 (a/n mode).
The idea is to connect BG clients to 2.4 and N to 5.
The problem is that 2.4 clients now started experiencing disconnects, basically it looks like 2.4 SSID disappears for a second.
My understanding is that if there are two APs with different bands then cannot possibly interfere with one another.
Any suggestions are welcome.
