So bascially, my internet connection comes through my modem, into an Ethernet port, to the wireless router, through another ethernet to my computer. Everything worked fine for years until yesterday. I could not connect to the internet through the modem to the router, but I could connect to it from connecting my computer to the modem (directly).
The error that I get is "DNS server isn't responding" (Your computer is trying to use a DNS server that is incorrect or doesn’t exist.). This error does not show when connecting my modem to computer (through ethernet cord).

Things I have tried to resolve this problem:
- unplugging and replugging the power cable to the modem
- resetting the wireless router
- netsh int ip reset (in command prompt)
- netsh winsock reset (in command prompt)
- system restore (came up with error, then restore point somehow got deleted)
- Changed wireless router (to see if it was a router problem, it was not)
- Booted in safe-mode (with networking), still no internet through wireless router
- Changed DNS server addresses to "22.214.171.124" (preferred) "126.96.36.199" (alternate)
NOTES: Could not find Microsoft Virtual Wifi Miniport Adaptor
OS: Windows 7 Ultimate x64 SP1 (english)
Modem: Motorola SB5100 Cable Modem
Wireless Routers: TP-Link TL-WR1043ND and ZIO WLB5254AIP
Can anyone help me? I've been searching through forums for HOURS and found little/no help.
EDIT: Thanks everyone, but it seems that I need to make a MAC Clone address.
Thanks for the reply.
The connection IS connected to the WAN input port (from modem).
Note that this suddenly occurred, meaning that it is (most probably) a software issue, and it is the connection from the modem to the router (or maybe it's just the routers fault) that is causing disconnection.
