Strange Belkin Wireless Problem

Do you have the router's DHCP client turned on? Otherwise, try turning it on. And, seeing that you are on a cable modem, you may have to re-establish your lease (register a MAC address) on your ISP's set-up page - if they have such one.

Here in Holland, the first point of contact needs to have a specific name. If it's the computer it needs a name beginning with cc and then a bunch of numbers. Maybe something to look at.

On the other hand, if you use NTL, you're on your own (bad experiences in the past).

I'm not familiar with Belkin, but if I saw that type of behavior the first place I would look at (DLink) is for the "Ethernet to WLAN interconnectivity" option to be enabled. Next, I'd start looking at DHCP, IP's, and filters...

However, those LEDs "going orange" is suspicious. These are the LEDs for the LAN port? Orange usually means that the wired connection is only at 10Mbs, while green means it is 100Mbs. That router could very well have a bad switch in it.

Brand new? Return it.

Are you trying to run two pc on the cable modem? One via the wireless and one wired. If you are, then you may need to place a wired router between the cable modem and the wireless router. The cable modem's dhcp may only allow one connection. By placing the wired router in between, the cable modem will connect with the wired router, which will also have DHCP also to link to all the additional wired pc's and devices. D-link, Lynksys, and other make these and they are usually under $50 for a four port model.

The F5D7230uk is a NAT router. I read what the OP wrote, that he plugged the PC into one of the router's ports.

Many thanks to all of you for your suggestions and thoughts. For various reasons I have not yet been able to try all of them out, but will do at the first opportunity and will re-post with whatever I discover.
