    I have ADSL modem/router ( Pronet PN-ADSL 101 E/U )(in bridge configuration)to which I connect my new Wireless N router(TPLink TL-WR941ND) (in PPPoE configuration). I connect PCs to my new router.

    I am able to access the Internet when I connect through new router (both
    wired and wirelessly), but some sites are getting blocked. Most notably
    yahoo.com (though ymail.com is working), Microsoft.com. msn.com.

    These sites work perfectly fine when I connect my pc directly to my old
    router and enter username and password manually.

    (However others like google.com. facebook.com works fine when connect through
    new router)

    So here these some sites need some parameter set but I am unable to find them
    out. Can anyone help me.

    My friend said he also faced same problem. Surprisingly he advised me to see
    if the same websites will work through Opera turbo mode and boom they worked. So
    what could be the problem?

    I  solved this problem. I checked the MTU size for my old router using following command:

    netsh interface ipv4 show subinterfaces

    Then I set the same MTU size for my new router. By default it was 1480. But my old router's MTU was 1460. MTU size is very dependent on your ISP and network backbone. So it has to match up.
