Solved Only some webpages working. (netgear router)

[Evolocity]

My computer is getting a weird problem, I'm unable to open some webpages only google, facebook, amazon are working. It happens only whenever I connect to my router(Netgear WNR612). If I directly connect my modem, everything works fine. My relatives are coming in 2 hours and they will need wifi, i really need to fix this asap. Please help!

I would go and buy a new router..

Okay I fixed it.
I changed the MTU to 1300 and the dns to 8.8.8.8.

Thank you.

Sorry I was no help, but glad you sorted it out.. I use a router and have never had to change any settings.. for me , it works or it does not work.
