Hello, so I have this problem. Yesterday, I was browsing web while my sister was checking facebook on her laptop (wirelessly)
Suddenly, both of us lost connection with the internet. Today, we still don't have connection. We cannot connect to our router with phone or laptop and my Pc cannot connect by Ethernet cable
All of the lights are on (DSL on, WiFi flashing as always, Internet on and power is obviously on). Troubleshooting came up with "Invalid IP configuration" but changing this configuration did not help. Restarting router also did not help.
My router is D-Link DSL-2780 (got it from TalkTalk). I am running Winows 7, it also is installed on all laptops. I'm posting screenshots of ipconfig and ipconfig /all
I ask for your help because my sister thinks that this is my fault and she is ready to kill me !
Sorry for my English.

Assuming your still with Talk Talk, have you tried their helpline (god forbid!). I know they can be a bit tedious but it is what you pay them for.
Your ISP will talk you through all the usual checks and identify the source of the fault, and if its identified as a faulty router they should change it for you.
