Problems sharing an RCS DCM305R

Jun 17, 2005 12:06AM PDT

I have a Belkin 11g wireless router that I'm trying to connect a laptop with (wirelessy) and a wired connection (Ethernet only - no USB usage) to my desktop. The ISP is Brighthouse.

I cannot get an IP connection on the laptop!
Are there any special things I need to do to clear old DNS, assigned addresses, etc. to share the connection? It seems the modem or ISP's server only recognizes the mac addr. of the desktop, not the laptop! Here's the symptoms:

I've left the RCA DCM305R unplugged for up to several hours thinking that was all that was need to clear the DNS settings, old IP addr., etc. But every time I cable-up the Belkin (modem output to Belkin's WAN port, Lan output of Belkin to desktop), this happens:

1)Desktop connection - runs fine
2)Laptop connection - no internet access @ all - wirelessly or wired into the Belkin router

Alternatively, I've unplugged the modem for several minutes / hours & tried cabling the laptop directly to the output of the modem...still no luck getting out to the net.

Looks like you found it.

The laptop has issues. But your post wrote so little about said laptop that all I can do is agree with you.

Actually, no I've not found the problem

When you say "the laptop has issues", What do you mean? I'vw used this laptop w/the Belkin (wirelessly) on a Verizon DSL connection...no problem. I never load a static ip addr. either. Someone on another forum suggested that the ISP could no assign an IP address to it....It could to the desktop (wired) but not the laptop. However, I'd unplugged the modem for several minutes & up to an hour...then plugged-in just the laptop..still no go.

Could it be possible that this ISP (Brighthouse) logs only 1 IP at a time which may take several hours to clear or reset?

You only need 1 IP, but I never duplicate web content so I'll stop writing how routers work.

Yes, you found the issue, but didn't supply any clues to work with.
