Random websites won't load ??

DiscoKandy · 18 May 2008 at 12:33

Hi,

Having problems loading certain websites, currently on AOL ( I know

). Most websites work fine, however the following refuse to load at all.

www.thomascook.com
www.tesco.com
www.hotmail.com

Tried resetting the router, used a different computer, just about everything. Any ideas ???

devel666 · 18 May 2008 at 12:42

Tried a ping test to the site, tracert test and a nslookup ?

DiscoKandy · 18 May 2008 at 12:53

Ping tested them all and recieved replies, not familiar with how to perform a tracert/nslooopup test

devel666 · 18 May 2008 at 13:00

Start Run cmd

tracert bbc.co.uk

or

nslookup bbc.co.uk

What browser you running ?

Anti virus software ?

Anti spyware ?

Router firewall on ?

Windows firewall ? other firewall ?

any pattern ie works at a certain time then not at others ?

Does this happen often or just today? It could be a problem with aol's dns, it should sort itself out after a little while,

try this: http://212.140.181.233 tesco website without dns, if it works you know it's a problem with aol's dns

I can access all three.(using aol)Can't access the be site though

Have you messed around with the MTU setting on your machine at all?

I had this problem and I ended up buying a new router which solved it.
There was probably a better work around but I was in the market for a new one anyway.

sounds like aols dns is playing up, tried using opendns?

http://www.opendns.com

try changing DNS on local machine to:

208.67.222.222 (resolver1.opendns.com)
208.67.220.220 (resolver2.opendns.com)

Remember to make note of old dns servers, probably 192.168.1.1 or similiar, for when you have finished testing and want to revert back.

sorry for the slow reply guys, been pretty busy with work.

Ok, yesterday evening everything was working fine once again, all good I thought, up until about an hour ago. I'm once again unable to access a number of websites inluding the three that I posted in my original post.

Haven't messed around with MTU settings etc, 3 machines that access the internet through the wireless router and all suffering the same problem.

Performed ping, tracert and nslookup test on websites I'm unable to access and I get replys from them all ????

Tried alternative DNS server too, no joy.

Cheers Guys

Take the router out of the equation and see how it works.

DiscoKandy · 20 May 2008 at 20:18

that would be a good idea, but I don't have an alternative to test.

Take it away, no alternative.
Just put 1 computer into the modem and see what happens.

DiscoKandy · 20 May 2008 at 21:16

its a router modem matey, and I have no standalone modem.

Desipte the router being unbranded I think ive narrowed it down to the following. Whats the issue with AOL and secure sites ?? It it suggesting I have to manually adjust the MTU on every machine on our network ?

Did you try clicking on the link without the dns?

DiscoKandy · 23 May 2008 at 20:45

yeah, no go mate. Think im slowly getting to the bottom of it. Appears to be a MTU issue, manually changing the MTU to 1400 in Vista makes everything work again.
