My BT router is giving me trouble. It would work for 3 - 4 day's and then like to-night i had to switch it off and on 4 time's to get it to work.

It say's the dns sever is not responding.

I did a BT diagnostic test for configeration and it said my " usb connection was down " if this is so how can it work sometime's.

The problem has been going on for about 2 month's.Your ISP is likely changing equipment or configurations causing change in their DNS servers.
Don't know why your testing says:  "usb connection was down".
Reboot modem/router will usually fix it.
You can see if your Public IP has changed by looking at my signature.
capture is the window's check

capture 1, i click ADD because it doe's not show my router

what do you think about capture 3 , the router doe's not seem to be listed.Is modem & router integrated (1 box)?  I can tell that's it's DSL, because it says PPPoE.
Can you ping router and/or modem?  You have to know their IP addresses.
At COMMAND prompt, type:  ipconfig /all
Copy & paste results here.
IP address is the computer.
Default Gateway, DHCP Server is the router
DNS Server is the ISP's.Thank's Computer_Commando, it's one box DSL.

sadly how do i ping 

i tried ipconfig /all and a black box flash's on the screen for a second and it's gone.

i think i have found the problem, see below

i think capture  no. 7 is the problem.

[recovering disk space - old attachment deleted by admin]Capture 4 has some of the ipconfig /all info
Looked it up:  http://www.melissadata.com/lookups/iplocation.asp?ipaddress=217.47.207.250
Computer in online.
Your Public IP is shown in my signature.

I think you're right about Capture7.  It could be the modem/router that wants a username & password.  Is Voyager 210 the modem/router?
I'm no expert on DSL (I'm on cable) & I'm using WinXP.
Who owns the modem/router, you or BT?
I worked on someone's DSL modem & it did have built-in SECURITY requiring authorization by the user of ADDITIONAL routers that were connected to it.

Capture 5 & 6 look identical.

ping & ipconfig are entered into the Command Prompt window
Command prompt window is this:


[recovering disk space - old attachment deleted by admin]is this the IP address i should fill in if i need to in any of the form's above, 217.47.207.250

I have found my name and password for BT so i will have to fill it into capture 7.

Voyager 210  ADSL router is the one i have.

BT own's the modem, i'm going to ask for a new one if i can't get this working.

In reply no.2, capture one, will have to add the router detail's as well. Quote from: harry 48 on July 18, 2011, 02:11:37 PM
