Right I am completely stumped on this one, so hopefully some fresh eyes on the problem may resolve it.

About 6 months ago i setup a wireless router for one of my customers on 8mb Freeserve Broadband, all has worked fine till a week or so ago.

He has 1x PC connected by LAN Cable, 1x Laptop connected by LAN Cable and 1x Laptop connected by wireless.

He also works from home occasionally and has access to his work by a VPN connection.

Currently he can get on the Internet but cannot see webpages properly, for example his homepage is orange.co.uk, half of the page will load then stop, if you go to google.co.uk, you see the page can search for stuff but as soon as you click a search result you get nothing etc.

This happens on all the machines. I have completely cleaned his machine and am happy there is no spyware or viruses, I have checked his machine at my shop on our network/router and it works fine.

If you connect at his house with his old Copperjet USB ADSL modem the internet works fine, whcih to me rules a line/isp fault out.

If you connect to the VPN that works fine, and you can browse the internet via their connection, pages open fine etc but it is obviously slower due to the VPN speed.

I have tried with his IE7 and with Firefox and have the same problem.

I said to him that it can only be his router (logically) causing the problem as it was the only common factor, I had tried resetting back to factory defaults and starting again with the settings checked against the ISP but all to no avail the problem persists.

He went back to PC World where he originally bought the router from and swapped it for a brand new although same model router and has set it up and called me today and says he still has the same problem.

I suggested we could try a different router but do not have one open to try. He is reluctant to spend more money on another router due to money already spent on original parts and my labour and PC World will only swap his router for the same model.

Could both the new and old routers he has tried be at fault? Have Freeserve changed something (other than being bought out by Orange etc)

Now i am stumped, please help, any ideas.

Thanks
 
Might not be exactly same problem, but I set up a network for sis-in-law, and she could access some websites but not others... turns out it was the router firewall blocking sites (or conflicting with Norton - I will get rid of this Norton stuff sometime!)

Disabling the router firewall sorted it.
 
Yeah sounds like something is blocking something along the line - does the router have a hardware firewall?
 
Don't think it would be router firewall as it hasn't been touched and was working fine, but will check, also there is no firmware update for router i did check that.
 
Meant to say he has been on the phone to Belkin and they say it is not router at fault?
 
Spoke to him today and he managed to get PC World to swap it for a Netgear Router (yay) and all is now working - bloomin crappy Belkin

Thanks Guys
 
Which phone line filters are you using?
I was having an intermitent problem and eventually found that it was one of the line filters that was b*****ed
 
Well it's all sorted now but it sounds like it might've been a problem with the MTF value, a common symptom is pages part loading missing bits, etc. Could be the ISP had changed something at their end that broke it...
 
Glad to hear that problem is sorted. I wonder if anyone can shed light on what we're experiencing at the moment then.

We have a "Livebox" wireless connection via orange. Desktop runs wirelessly via a USB plug-in doobry and is running just fine. The laptop is meant to run via it's own wireless card "thing" (sorry - crap at the terminology! internal Inventel wireless wotsit anyway) but for some reason it's refusing to remember our WEP key for more than about five minutes at the moment - you have to manually input the WEP key when you start up to get it to connect at all and then once it has connected it drops out after a few minutes and next thing you know it's lost the WEP key again, thus you have to repeat the process. :bang:

The only thing that's changed is that someone in our block has just got wireless broadband via NTL - the wireless gizmo in the lappy finds that signal immediately after finding ours - could that be causing a conflict do you think?

:help:
 
could be, check in the advanced settings and delete any preferred networks you find setup in there. Then re-search for any available networks and connect to yours and re-enter the wep key and see if that sorts it out.

The advanced settings are an option in the "view available wireless networks" window.
 
check the channel of yours and the neighbours wireless and make sure they are more than 3 apart. So if one is set to channel 3 then the other must be 6 or higher
