Hi guys

Got this rather irritating problem, which has just started occuring, in that the internet would drop for a couple of minutes every half hour or so. We have Virgin media cable. The router we use is a D-Link DI-624, bought only a couple of months ago, the wireless does drop occasionly but thats normal, its as if like someone turns off the DNS servers (we use OpenDNS). As firefox suddenly start "Looking up" all sites, and then MSN signs me out. I have replaced all cables but no avail..

Help appreciated. Thanks

That error means that either your router didn't supply the system with an IP address. Or the system couldn't connect to the router to get the address.

If you go to start select run then type services.msc can you find the DHCP service and is it set to started and automatic?
Also can you log into the router and check its status is ok.
Regards,

Alan.

DHCP service is enabled on all machines. Also i keep getting a popup saying windows has connected to my network but says its unsecured when its not which is weird. But that doesnt cause loss of internet.

Are these systems XP Vista etc? Have you made any changes to these systems prior to the problem?

I would first check the router setup and if possible reboot the router.
Can you check the settings on the other systems and compare them to the problem system.

Also, what security products are being used?
Regards,

Alan.

I would consider ringing Virgin and asking them if they have had been having problems with the service in your area.

Hmm =/

I have a hunch that this is not a virgin problem.

I did a tracert to the cable modem and router when the connection died.

Tracing route to 192.168.100.1 over a maximum of 30 hops (Cable Modem)

1 * * * Request timed out.
2 * * * Request timed out.
3 * * * Request timed out.

That should be 2 hops. (I had to cancel the rest as it was pointless.

Tracing route to 192.168.0.1 over a maximum of 30 hops (To router)

1 * * * Request timed out.
2 * * * Request timed out.

Should only be one hop, but again i had to cancel.

:thumbsup:

It sounds like the router is blocking the system can you log into the router to check settings?
