@LarryMan For now it works flawlessly with the ax11000. Too bad that these firmwares give so much trouble

@Leonlay I just bought a new router (Asus AX11000) Now I don't have any problems anymore and my internet is how it's supposed to be 1gbps down and 1gbps up No tp-link for me

@Paul_Tan Is there already a fix for this issue? as it is very annoying. I also contacted my ISP before, but they could not see any issue. And then i found this thread. I installed the BETA firmware...
