Honestly, based on the first post, my best guess is that the cable modem is plugged into one of the router's LAN ports, rather than the WAN port. tooki

Appreciate the suggestion tooki (and I'm the first to suggest simple obvious things when trying to assist other people), but that's not the problem. The cable modem's been in the …

I think you're right, Thorin - it sounds like your router's malfunctioning. If your hostname is getting changed to an ISP address, that certainly indicates that the computer is get…

To replace a WRT54G that you've been happy with, I'd say go for a WRT54GS. It has more RAM and ROM so it can handle more traffic throughput, and bigger third party firmwares (whic…

OK, well if it's all plugged in right, I have one other suggestion: In the "Advanced Routing" tab of Setup in the router, what is the Operating Mode set to? It should be set to "ga…

Again, thanks for all the help peeps. It is set to Gateway, and the DMZ setting is disabled . Can I just confirm that nobody thinks this is likely to be being caused by changes t…

Woah! I didn't see anything about ISP software... Please give details! It's quite possible that their software DID do something to your laptop that keeps it from getting an IP f…

Unplug the router, modem etc... Plug the computer directly back into the modem, and then turn them both on again. Get the IP, and now go through the procedure of connecting the r…

I set my system up! I couldn't register my new cable account without running their software. ghporter, I've described the ISP software in the original post. In the last paragrap…

Thorin, I missed that in my original read. Sorry, because I think what's going on has a lot to do with what the software did. From the log it looks like it did a number of things…

Before I moved house I didn't have any of those settings in (though I will try as you've suggested). I knew it set up an email account in mail, which I've left because it's actual…

Just to clarify, things like my 'broadband PIN' were just used to match my account/billing details to this installation, it's not stored anywhere on my computer in any settings. I…

Never let the cable guy touch your mac. They only lay cable.. most don't know anything about setting up a mac.

Fixed it. I'd tried it with another powerbook, and encountered the same problem. Whichever book connected first got the external IP address from the router, the next to connect g…

Stuff breaks, wears out and dies. This is life. Getting the stuff replaced and having it work right away is cool. Congrats!

The WRT54G had been on 24/7 for over two years, then had been unplugged, stuffed in a box and stuck in a garage for a month. The last piece of networking kit to break on me was an…

I think you have to use the MAC address cloning feature of the LinkSys to clone the MAC address of your PB. When you first connect your PB to the modem and ran the setup software…

Yeah I'd already tried MAC address cloning. I also went away for a week and left both the router and the modem switched off, which should have cured that problem were that the cas…

Have you tried updating the router firmware? If the old firmware is corrupted, that might solve the problem.

I'm going to be switching from DSL to Cable, and in doing so I'm gonna lose my static IP. Since I run a server, I'm going to need a dynamic dns service, and I'm wondering which th…

Try ZoneEdit (www.zoneedit.com). They'll cover you on both counts.

http://www.dyndns.org I've used them for about 4 years, they're great. I think it's $20 a year to use your own domain, so that doesn't qualify under your free requirement, but $2…
