expertec Posted January 12, 2005 Report Share Posted January 12, 2005 Try going to an IP address like 212.58.240.110 (bbc.co.uk) and see if that works. Quote Link to comment Share on other sites More sharing options...
homecomputeraid Posted January 12, 2005 Report Share Posted January 12, 2005 I usually start by pinging the Gateway then out. If you can reach your Gateway, then ping the outside IP of the Router, then your ISP's Router. If you can ping to the inside IP of the Router, and the outside IP of the Router, but can't browse the Internet, it's an ISP problem.You can also make sure name resolution is working on the network by pinging a web address like www.cisco.com and making sure it resolves to the IP, and the pings go out. Name resolution problems could be ISP related, but are more likely something on your network. Quote Link to comment Share on other sites More sharing options...
Andy-2004 Posted January 13, 2005 Author Report Share Posted January 13, 2005 ok....its looking good i think...he can ping the bbc site an acess it by ip adress but cannot access it or any other site by url...thanksAndy Quote Link to comment Share on other sites More sharing options...
homecomputeraid Posted January 13, 2005 Report Share Posted January 13, 2005 Sounds like a DNS issue then. You could see whether there was a change to your ISP's DNS Servers. Do you know how Domain Name resolution is handled on that network? Do they have their own DNS Server that should be checked out? Quote Link to comment Share on other sites More sharing options...
Andy-2004 Posted January 13, 2005 Author Report Share Posted January 13, 2005 by work computer i mean that its one computer with a router connected to it then a wireless broadcast to a lap top that goes out on site...he comes into the office with the laptop and updated the computers files using briefcase...how could i check out the DNS server stuff?he is on BT brodband Business...http://www.bt.com/index.jspthanks Quote Link to comment Share on other sites More sharing options...
homecomputeraid Posted January 14, 2005 Report Share Posted January 14, 2005 Sorry Andy, I was picturing a larger corporate network. :)If he has a Wireless Firewall/Router, that should receive the DNS information from your ISP, and distribute that to the computers that connect to it. You might try unplugging your cable modem, unplugging the router, plugging the cable modem in, waiting until it is fully up, then plugging the router in to refresh the DNS information. Do you know how to get into the Router's management page to check it out? Quote Link to comment Share on other sites More sharing options...
Andy-2004 Posted January 15, 2005 Author Report Share Posted January 15, 2005 Its a router/modem/wirless/bulit in everything thingie....you know what i mean....and yes we can get to the config page by the 192.168.2.1 type adress Quote Link to comment Share on other sites More sharing options...
scuzzman Posted January 15, 2005 Report Share Posted January 15, 2005 You can try flushing his DNS resolver cacheipconfig /flushdnsIf that doesn't work, try manually specifying his DNS servers...Post if you need help in doing so. Quote Link to comment Share on other sites More sharing options...
Andy-2004 Posted January 18, 2005 Author Report Share Posted January 18, 2005 hi...flush DNS didnt work...could you post the method for manually doing it? Quote Link to comment Share on other sites More sharing options...
homecomputeraid Posted January 18, 2005 Report Share Posted January 18, 2005 Andy,I suspect your Internet Service Provider changed something with DNS. Contact the ISP and find out the Primary and Secondary DNS Servers. Make sure those are in your router. Please post the manufacturer and model of the Router so we can help you find the information if you need help.Sincerely, Quote Link to comment Share on other sites More sharing options...
Andy-2004 Posted January 18, 2005 Author Report Share Posted January 18, 2005 The ISP is bt broadband Business and its a BT Voyager 2100 DSL router modem thingThanks for the help Quote Link to comment Share on other sites More sharing options...
homecomputeraid Posted January 19, 2005 Report Share Posted January 19, 2005 You can download the manual for the Router thing here:http://www.voyager.bt.com/2100/downloads.htmTo get to the router configuration, you open a browser like Internet Explorer or Firefox, and browse to the router's inside IP (most likely 192.168.10.1). Login to the window that pops up (probably admin for username, and admin for password unless you changed it).Look on the Status, Overview page and write down the Primary and Secondary DNS Server information. That's the information you will ask your ISP about. Ask them if the DNS server addresses are right.It seems like DNS server information would be passed to the internal computers using DHCP by default, but if it's not already set up, here's what the manual says to check:DNS Server The DNS server address will be passed to the DHCP clients along with the IP address. The DHCP clients use the DNS to map a domain name to its corresponding IP address.To enable the DNS Server: Tick the Enable automatic assigned DNS Click ApplyRestart your BT Voyager Router. How to restart...Another way to test to see whether the router is a problem is to connect the PC directly to the Cable or ISDN Modem. Reboot the PC and the Cable Modem and see whether the PC can get to the Internet. Has this ever worked, or is it a new setup? Quote Link to comment Share on other sites More sharing options...

homecomputeraid Posted January 19, 2005 Report Share Posted January 19, 2005 Sorry this is taking several days for us to help you resolve Andy!Does your Voyager BT Router plug into another device (cable or DSL modem) to get to the Internet, or is the Voyager BT Router the only device you can plug into to get to the Internet?Is it PC ---> Voyager BT Router ---> Cable Modem ---> Internet?

Andy-2004 Posted January 19, 2005 Author Report Share Posted January 19, 2005 problem solved!!!the primary and secondary DNS servers were mixed around!!Dont know how it happened but its fixed now! Quote Link to comment Share on other sites More sharing options...
homecomputeraid Posted January 20, 2005 Report Share Posted January 20, 2005 Normally, that shouldn't cause a complete inability to resolve names on the Internet (that's why there's a primary and a secondary, if either one's working you should resolve names), but whatever works! Hope we helped. :) Quote Link to comment Share on other sites More sharing options...
