Solved Can’t Open Certain Websites With PPPoE But With Bridge Is Ok

  • 4

Hello,

I have two Wifi router with me and a BSNL, India Broadband connection with me. The two modems are:
WA3002g
and ZyXEL P-660HN-T1A.

I could easily access all the websites through my WA3002g which was configured for Auto Dial through PPPoE Encapsulation method till suddenly one day it stopped working completely. So I put it into the bridge mode and my internet started working again. I thought that maybe there is some problem with the WA3002g so I purchased a ZyXEL P-660HN-T1A Wifi Router and configured it for Auto Dial with PPPoE.

The internet worked fine except now I am not able to open certain websites like mail.yahoo.com, http://wirex.in, and then linkedin.com didn’t load properly.

But when I configure it for Bridge Encapsulation and use a Windows dialer all the websites load very fine.

I have checked it on 3 laptops with Windows XP Professional, Windows 7 Home OS.
The websites load fine on my mobile phone (Nokia E71) through opera mini but not through the inbuilt browser.

I tried to do many things by looking up on help forums through Google Search like changing the MTU size for router and Windows, Resetting the Netsh>winsock, flushing the DNS servers, Using the Open DNS servers (Google and Open DNS), Disabling the router Firewall, but it didn’t help at all.

This is an unusual problem for me. Please help me loading all the websites with PPPoE as well.

If you need any other information I would provide it here.

      After so much of trouble and putting up my mind to this issue I have come here to tell anybody who is facing this problem that the issue is solved, for me at lest. 🙂

      Here is how it happened:

      After getting troubled for past 10 days I today got another router (Teracom T2-A) from my cousin’s home and to my amazement there was no problem with the router configured for Auto Dial up with PPPoE mode. So I could know now that there is a problem with this new router and my old WA3002G. So I tried to change many settings like Disabling the firewall, disabling NAT, adding more connections in the WAN settings other than VPI/VCI 0/35 like 0/32, 8/35, 8/81, 0/100, 14/34, 1/41 (these are for BSNL Broadband, India) but none solved it. In fact disablign the NAT worsened it and I could not open any site.

      Then I tried changing the MTU values and I tried to put it to 1510 to which I got a warning that it should be between 100-1500 and 0 is for default.

      I put it 0 and BINGO!! the problem is solved. Now I can open all the sites easily. 🙂

      I know its a little confusing because I tried many things like disabling the firewall, adding more VPI/VCI etc but I think the problem was with MTU only.

      I would like to reset the modem to factory settings and see if putting the MTU value 0 alone solves the problem but right now I don’t have the courage for that as I am happy browsing all the sites after such a long time!!!

      I would try putting the MTU 0 for my WA3002G as well and would post the results soon.

      So now this problem is SOLVED.
