I bought the TPLINK Wifi 6 Archer AX3000 to go with my existing range extender re650 and the uploads for the re650 are getting stuck at around 20 mbps with two different devices in my house (maybe more). My connection is 150/150 and I was getting much higher upload speeds before with the Archer 2300 router. It was working before and now it's not. My download speeds are 140 with the re650 now though which is good. Can someone please tell me why the slower upload speeds with the newer device? I have the latest firmware update on both devices.
Upload speeds not good with new Archer AX3000 and RE650
