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!
