Randomly DSL Disconnection
Hello
My device is TD-W8151N and it's working for 7 years or more.
Before getting to the point, a while back my modem adaptor got broken. After about two weeks I replaced it with a 9v 0.8A TP-Link adaptor which the original one was 9v 0.6A. some weeks passed and I noticed modem disconnection (The DSL light goes off and consequently the Internet light. A few seconds later light gets back and modem tries to connect the Internet which is successful). Sometimes when it doesn't disconnect, the ADSL speed plunges.
I tried different settings and no luck, although I think I get a more stable connection with changing ADSL Mode from "auto-sync up" to "ADSL2+" in advanced setup.
So I want to make sure If there is any possibility that my modem is not functional anymore or my cabling has no more capacity before trying to contact ISP.
Thank you.
