DNS Problems

    Could be wrong with the title but I think its the cause of my problem. Gonna give as much detail as possible.

    IBB connected to wireless router. 1st Pc connected to router with wire - no connection problems. 2nd PC connected to router wirelessly - no connection problems (using this PC to write this). 3rd PC (Dell Inspiron 510m) connected to router wirelessly - connection problems.

    All machines are assigned ip address automatically and the laptop is given a correct ip address. Router is 192.168.1.1 and laptop is 192.168.1.102. I can ping router and other PCs. I can also ping domain names and ip addresses. For example I can ping www.goggle.com and it resolves to 66.249.93.104 and i get 4 replies.

    However I can't connect to any sites using IE, or use GMail Notifier, DOS ftp, telnet etc. In IE i can see its has resolved google.ie to its ip address and is trying to connect to it. And eventually fails (Page cannot be displayed) . Same thing happens if i type in an ip address into the address bar. In other words any network connectivity does not work.

    Last night it was working fine. I had uninstalled the Norton Internet Security 2005 trial that came with laptop and replaced it with AVG. Network connectivity was working fine after this, including after restarting.

    Today I used SymNRT to make sure all traces of Norton were removed. I also uninstalled AVG. I also disabled windows firewall. (no other firewall installed) I ran the Winsock Fix and still no joy. DNS client service is running fine and nothing in the Event viewer indicates a problem. Finally I ran a Windows repair from the Windows installation CD. Still the same problem.

    Has anyone any ideas about why it won't connect? Let me know if any more details are required.

    Thanks

    ok bit of an update here.

    Was working on this prob a bit more last night. In the process of which i turned off all 3 PCs, the router and the IBB IDU. Then rebooted router, IBB and all 3 PCs. And they all had the same prob as PC 3 outlined above. Now in the process of figuring out wtf was going on PCs 2 and 3 came back online (again I'm using PC 2 to write this). But PC 1 remains offline.

    2 and 3 are wireless. PC 1 is wired to router.

    Router is a Linksys WRT54G with firmware v3.03.9. When all 3 PCs had no network connectivity i was able to view the online control panel of linksys at 192.168.1.1 and ping and traceroute to several different sites. But still nothing on PCs. Then without really doing anything 2 and 3 worked again. And still do on reboot this morning.

    I have no f**king idea whats going on? Anyone got ideas???

    Thanks

    ok i connect PC 1 directly to IBB IDU and no problems. So guessed problem had to do with router. I had previously powered off the router, waited 20 secs the npowered it on again. Still same prob.

    This time round I pressed the reset button and it restored itself to the factory settings. I configured it back to the way it was before and now all 3 PCs seem to be connecting ok.

    Fingers crossed thats the problem solved!!!
