Hi
I had a very miserable week thanks to my broadband connection. Maybe you can cheer me up…
Here the details:
I have a PC:
XP, SP2, Mozilla Firefox as default, IE6
I have a laptop:
XP, SP2, Mozilla Firefox as default, IE7
I have a wireless router:
Belkin, WEP 64 secured
And I have a NTL-Box (Virgin Media) broadband.
From one day to the next the internet stopped working. Well actually it didn’t stop completely. The NTL-Box still shows the connection light. The router (192.168.2.1) still says internet is connected. The network connection still says excellent.
When directly connected to PC (without router) I get the correct IP address (86….). This has been confirmed by Virgin Media
However, when I try to open a web-page it always tells me “Error, cannot open page”.
I have tried the following things:
- Re-booting the NTL-box many, many times
- Removing the router and directly connecting PC (and later laptop instead) via Ethernet.
- Re-provisioning to NTL-Box and assigning computer/laptop/router.
- Turning the Windows Firewall off
- Turning the router firewall off
- Removing all networks and setting up new wired LAN connection
- Installing new wireless network after wired LAN didn’t work
- Changing the security setting of Mozilla and IE to minimum
- Ping to NTL-box on 86… when router not connected. Ping gets returned perfectly.
- Ping to NTL-box on 192.168.2.5…when router is connected. Ping returned fine also.
- Tried to turn off (and certainly also “on”) Auto Remote Settings in Admin Tools/Services
- Tried different webpages but get the same problem with all of them
- System restored to 2 weeks ago when my world was still in order. Problem still there.
- TCP filter activated
- IP address given by DCHP
- I tried everything stated above on PC/Laptop, with and without router, in safe mode and in normal mode.
As mentioned above, all my analyses tell me that everything should work fine. However, it obviously doesn’t work fine.
The is only one thing that looked odd to me. In my network properties (support) the DNS address was still set to 194.168.4.100 and 194.168.8.100 although the router wasn’t connected anymore, the NTL-box was already re-booted & the support window already showed the correct IP (86… instead of 192…). However, I even tried to manually assign the IP address and I un-ticked DNS and removed the 194.168.4.100/194.168.8.100 but still, no webpage can be displayed.
Here the questions:
- Is it possible that there is a firewall that I don’t know of (additional to Windows, Belkin, Virgin, on both computers, PC and laptop)?
- Some might suggest that “windows auto update” has changed something. But why did restoring the system not change it back to working conditions again?
- Why can this happen over night without changing anything (not even new software installed).
- Is there a chance that the NTL-box is broken although it still shows up as connected and perfectly in order and still returns my pings?
- I am willing to re-install Windows XP and flatten my hd if this will help. Does anyone think it could help (considering that restoring the system didn’t help at all).
- Is it necessary to have the same connection setting in Firefox and IE, even though one of them is default connection?
- Any general ideas about how to solve the problem?
I am clueless…

Hi afeichtner,
Some ideas for configuration:-
-Don't wipe the HDD. Sounds like the problem is not there anyway.
-Set your wireless router / base-station as 255.255.255.0 , 192.168.1.254. Enable WEP/WPA security (passphrase etc)
-the ntl router should be set as 192.168.1.1.
-the ntl router should be set as DHCP server. Subnet 255.255.255.0. Start address (DHCP range) 192.168.1.2.
-Your two XP boxes should be set to acquire IP from DHCP. Remove any hard entered DNS settings as DHCP will assign these automatically.
Some ideas for fault finding:-
With the above configuration:-
-On an XP box, check you are getting the right config from DHCP as follows:- From command console (Run| cmd.exe), ipconfig /all. It should read as follows:-
Subnet: 255.255.255.0
IP: 192.168.1.x (where x is greater than one)
DNS: 192.168.1.1
DHCP enabled
-Router and wireless test: ping 192.168.1.1.
-Internet connectivity test: ping 158.152.1.65.
-DNS test: ping broadband-help.com. If there is a response, DNS is now working correctly.

Hope this helps.

I might try and suggest something.
Dont know if i am right but try and check if any latest updates by Microsoft and then uninstall them.
Rather than restoring the PC.
Also try and check if you can get access by uninstalling the firewall and then install it again.
Regards,
Brad
