Suddenly some webpages stopped loading for me, in Firefox, Internet Explorer, Opera and Safari, but not, interestingly, in Lynx. I used a BT Home Hub, and no changes had been made to my system for weeks.
NOTE Before you try anything below: Have you recently run a windows update? Yes? Okay, unplug/reboot your modem/router for 5 mins, then re-start and re-try. In many cases this solves the issue. A bug with windows update perhaps?
Most of the pages that stopped loading seemed to be behind an admin barrier of our company website, so I assumed the problem was there, but could log on as a colleague and had the same problem. Also, when he logged on as me, he could access all pages.
Next I tried using a laptop instead of my PC, and had the same issue.
So, the problem was with my internet connection.
Of course, I tried reboots of by PC and the BT Home Hub.
Interest: I tried copying a page that wouldn't load, line by line, into a blank page. It worked until I reached 1200 bytes, then failed. Remove a byte to 1199 B and it worked... I thought this was it, but then found that I could load other pages larger, and some smaller pages still refused to load. Another thing, adding an ASP Response.Flush to the top of the page made the page load!! - but this wasn't a proper solution)
I did a lot of reading, but nothing was really the same that I could find, not exactly. But I did find a lot of people talking about similar issues but with particular websites. For me, I could access some pages in a folder on one website, but not others, which confused me.
Anyway, a lot of people talked about MTU settings, and how changing these fixed their own problems. Worth a shot, I think.
Anyway, you can't change MTU settings on a BT Home Hub easily, so it seems. So I downloaded Dr TCP which allows you to set MTU for each network adaptor etc on your system.
Only when I altered my MTU as above and rebooted the hub again did everything work. I hear that this happens with BT fairly frequently.
CommentSome pages load, some pages don't, in any browser comment by RalpharamaHits | Last Modified 2009-03-11 And again. This time MTU changes did nothing. NOr did anything else. Very, very frustrating. I noticed this was happening on my laptop as well as PC, so must be a router problem? I actually turned off my Home Hub for 5 minutes (everyone says they do, but who waits 5 minutes?) actually 5 minutes. When it came back on it worked. I had already tried a reboot/restart option from HomeHub admin pages and that did nothing...
