Connection to router stopped working.

I've recently changed my ailing Netgear DG834GT to a Speedtouch 585v6. It seemed fine for a couple of days, but has now started giving problems.

Basically, any connection wired or wireless may or may not successfully connect through the router. The (WinXP SP2) tray icons report connected, the properties dialogs report the correct numbers, and trying ipconfig /all at a command line show the same correct IP addresses. Trying to use the connection simply refuses to talk. It wont even ping or tracert to the router or anything else on the LAN. Traffic monitoring, such as a firewall or built into the wireless driver, seems to indicate no traffic is even being sent over the link.

I've set the PC IP address to static, with the correct netmask. The gateway and DNS are set to the IP address of the router. This is exactly the same as what happens if the connection is set to use DHCP. The IP addresses are valid and consistent for what the router expects.

Telling Windows to repair the network connection (sometimes needs to be done more than once) or disconnecting and reconnecting will eventually bring the connection to life. Everything then works perfectly.

I've disabled and even uninstalled the firewall (I was using ZoneAlarm). I've now installed Comodo, and have the same issue. I've upgraded to the latest firmware and drivers for the network cards, wireless cards, router, etc.

Non-Windows-based computers connect without fail every time. Wired or wireless.

What's happening? Haylp!!

I have always found that DHCP works better. Why are you using Staitc IP addressing? What do you mean that your 834 was ailing?. I have found that they tend to work or not AND they have two years warranty from Netgear.

I was using DHCP, but tried using static to see if the problem would go away. Normally the first thing anyone suggests is "turn off DHCP to see if that helps"...

The routing functions were fine, the modem was becoming unreliable. It's older than 2 years.


The problem I have is that the connection through the Speedtouch works - sometimes. There is therefore little wrong with the basic config. Sometimes it will just work, other times I have to "repair connection" 2 or 3 times to make it work. Once it starts working it stays working until the PC is powered down. I have not yet been able to determine what changes between working and not working, as the properties, IP addresses, status, etc, all show the same in either case.
