Superhub One PC cannot access some sites

navman · 02-08-2011, 11:39

Hi Folks..

I have just got the super hub and it appears to be working fine as far as speed is concerned.....

It may be a coincidence but since then my desktop cannot access some sites www.t3.com being one. I have tried hard wired and wireless without any joy. As soon as I enter a proxy in, webcache.virginmedia.com it works fine albeit slow...very slow.

I get the same issue with Firefox. IE and Chrome

All the other PC's IPhones etc work fine and can access sites such as t3.com.

I have checked for Trojans and virus problems etc but all appears to be clean.

I have pinged t3.com and there are no lost packets etc.

As I say the superhub may be a red herring. I have contacted Virgin and on teh second attempt got through to someone who knew more than me :-). He was very helpful and went through several checks without any joy. He spoke to his supervisor who said it is the PC at fault.

Any ideas at all folks I have reached the end of my knowledge....

Cheers

Bob

when you ping it from your pc are you pingng the name or the ip address?

kwikbreaks · 02-08-2011, 20:46

Have you ever manually assigned the DNS on that PC?

It sounds to me like the VM supervisor was correct in blaming the PC if others on the same network are working OK but of course that doesn't help with fixing it.

Thanks folks, I pinger the name and no I re the DNS on that PC.

Not sure what you mean there .. the term "pinger" suggests your not 100% sure what you're doing ..

Sorry typo I pinged the address not the ip address

General Maximus · 03-08-2011, 07:51

just out of curiosity can you try using a different dns server. If you go into control panel, click on network connections, right click your network connection, right click and properties, click tcp/ip v4, click properties click on use the following dns server addresses and type in 8.8.8.8 and 8.8.4.4, these are the addresses for the google dns servers. CLick ok to come out of all of that.

Click start, run and type in cmd to bring up a a command prompt and type in

ipconfig /release

and then

ipconfig /renew

and this will clear all your old settings and bits that the pc was using and get new ones with the new dns addresses.

If this works you can over write the dns servers the hub uses (hopefully) so your whole network will go to google for name resolution and not VM.

(and before anyone starts whining, I know it doesnt look like he is having a problem with DNS, I am just curious)

Thanks for the reply and I am at a stage where I will try most things...

Tried that and no joy I am afraid

One thing you can try but I doubt it will help tbh is to right click on the connection icon in the system tray and select "repair". Note any error messages that may appear.

Is it only some sites that fail? How exactly do they fail? What messages?

That's one of the (many) features the Superhub doesn't support.

Maybe I should have said I am running windows 7 on the PC that is having the problem. I have tried the troubleshooting option and I get this message

Website www.t3.com is online but isn't responding to connection attempts

It is only some sites that fail. TY3.com is one of them.The error message I get when trying to connect to these websites is

The connection to the server was reset while the page was loading.

Thanks again for helping... I appreciate it

So, ping is ok, so let's try the next stage.

From a CMD window run "tracert t3.com" (without quotes)

Let's see if the route to t3 is short and sweet. Look for any hops along the way that show particularly high ping times and see if the complete route shows successfully. If any hop is odd, try again a couple of times to see if it improves.

If that completes OK then the problem is almost certainly in your pc, but that's for later.

navman · 03-08-2011, 11:15

Thanks again for the help...

These are the results of the tracert

Dai · 03-08-2011, 12:50

OK. That all looks as it should. What you have established with the ping and traceroute is that a valid connection exists between your pc and the target webserver.
So, what remains is to establish why your browser cannot connect. I see you have already tried a variety of browsers without success so it's unlikely to be settings within a specific browser. That narrows it down a bit.

I'd like to try overriding the DNS settings in your hub to try the google dns servers. From the Network and Sharing center click on your connections: Local area connection and click on 'properties' button.
Highlight Internet Connection Version 4 and click 'properties' again. At the bottom of the page put a dot in 'use the following dns addresses' and fill in 8.8.8.8 and 8.8.4.4
OK out of that.

Now from a cmd window do 'ipconfig /flushdns' without quotes.

Now try browsing to t3.com without any proxy set.

navman · 03-08-2011, 13:15

Done all that and no change. Still the same message :-(

kwikbreaks · 03-08-2011, 14:15

It sounds to me like your network type may not be set to "Home network" and your firewall is blocking you from connecting.

Right click the connection icon and open the network & sharing centre. Your active network needs to say "Home network"

When you first connected to the hub Windows would have asked what network type it was and I'm guessing you didn't select "home network".

If it isn't Home then click on the link saying what it is (Home, Work, Public) then click on Home in the window that opens.
