Hello, I am looking for help regarding my wireless Wi-Fi extender, the home I live in is old and has bad wiring and for the most part bad signal so I am forced to use this. I have a TP-link AC750 Wi-Fi Range Extender. When on the 2.4hz channel of the extender the Wi-Fi is consistent but very poor getting speeds around 10-15 mpbs. When on the 5hz channel the speeds are much better hovering around 80 mpbs, the only issue is that it frequently cuts out 1-2 times every couple of hours making it very frustrating to work around. Is there way to make stop this from occurring? I have it fully updated to the latest firmware so I am unsure of the exact cause, the distance from the original source of Wi-Fi is only a few rooms down so I don’t think that is the issue. Any and all help would be appreciated, thanks.
