I want to be able to switch to 40 MHz width 2.4GHz ONLY. The only option I get that even comes close is 20/40 Ce, eC, and XX. I just want 40 Ce, eC, and XX. Why can't I have just 40 MHz width? It wouldn't matter for WiFi certification because no Mikrotik device is technically WiFi certified, and RouterOS is supposed to give me all the options despite the troubles a misconfiguration might cause. What gives?
