I was logged on using the internet and all of a sudden it stopped. I have a TP LINK TD-W9970 Version 2 modem. Looking from left to right, I have the Power "ON" light, the "DSL" light, NO "internet" light, the "WIFI" light is on, followed by four more which are all NOT "ON" (and never are) and to the very right, the "LAN" light IS on. (I do not recall seeing this final one "ON" before?).  I have tried turning the modem off for 30 seconds and turning it on but that has achieved nothing.  Does anyone have any suggestions? I'm not particularly technical with computers but willing to give things a try! I googled the user manual but cannot figure out what my issue is. Thankyou. ... View more
