Archer D9 xDSL internal Error
i have an error with my tp link Archer D9, i turned it off normally but when i wanted to turn it back On the next day it doesn't recognize my adsl cable anymore and the xDSL LED stays off whatever i do, i checked all cables my phone works i checked with another modem it works so the problem is with the D9 and whenever i try to reboot o reset it always in the UI it always shows interal erros "1" and "9003" and the interface is very slow. I don't have any devices near or connected to the router, I've had this problem once before like 6 months ago it lasted one or two hours then the D9 worked back normally, now the problem is persistent its been more than 48h and i don't know what to do. The router is still like new any help plz !!?
