I've had a Netduma for about a month now and everything was fine, then as of a couple nights ago my wifi won't go over 20 mbs. I have 300mbs fiber. My hardlined desktop gets the full 300 mbs but anything on wifi struggled to get above 15 mbs, website don't load on most devices, and I can't even watch tv. When i run connection benchmark in dumaos it shows my full 300 mbs. I've tried disabled QoS, changing channels on 2.4 and 5ghz, and even did a factory reset. My kids are struggling to play games and downloads are maxing out a 15-20 mbs for them. I can't refund the router because i've had it for months now, but my house was destroyed by Hurricane Ida, and we just got back into our house with services again so I took it out the box last month. Any help would be greatly appreciated.
