I insisted that their DNS servers are down. I couldn't ping them, and they would not resolve any URLs. I could browse by IP, but not by URL.

Amazing, I do have some problems with DNS me too since a week or so. I have to refresh sometime 10 time before the page get finally located and loaded. I will try to investigate if my router (SMC WI-FI) use the good DNS.

Joe,

Normally the router doesn't care about the DNS servers.

What might happen is that the PPP or DHCP (depending on what they use) from the ISP tells the router the DNS addresses. The router then can relay that to computers on the LAN (probably with DHCP). Something must be going wrong in that chain of events.

Restarting the router isn't enough? It may be difficult to tell, because your PC may cache the DNS addresses from the last session if the router can't tell it what they are.

Joe, drjohn - thanks

It's odd - some sites I can get to if I use the ip address, and others it doesn't matter whether I use the address or the domain name. Hope this worm is done soon...

thanks again,
neye

jhalada, got that router issue fixed? Assuming you don't have a fixed IP address (most people don't), you should have your router configured to get its IP address and DNS addresses automatically from the ISP. It will be given a 'lease', which means that the information will be periodically updated (according to the ISP's server settings). If the ISP is well run, they won't pull an old DNS address until all clients have been updated to a new one.

Now, your PCs should be behind the NAT feature (network address translation) of your router, so that you have internal IP addresses. Generally this is done as a one-to-many NAT so that your whole network looks like a single IP address to the outside world. It is your choice whether you want to use fixed IP addresses on your PCs or DHCP (assigned IP addresses from your router), but since the DNS servers can change, you should configure the PCs to get their DNS addresses from the router (who will get them from the ISP).

The simplest thing is to configure the router as a DHCP server and leave your PCs as DHCP clients. Then, every time you boot up you will get a fresh IP address and the current DNS addresses. (If you have a particular device, such as a print server, which is more easily administered with a fixed IP address then that can be a special case. Assign a fixed IP address from a range that is excluded from the router's DHCP server range.)

Let us know how this works out for you.

I've changed the DNS in the router to point to my ISP official DNS primary and second alternate DNS. The router was taking the last ALTERNATE as primary and the primary as alternate. If all DNS was same speed I doubt that my change was necessary. Anyway... it work good for now but the problem was intermittent. If it re-appear I will notify.

Joe, I allso use a LinkSys router.
Most of them use a default internal IP# 192.168.1.1 if you type it in after http;// in your URL the LinkSys setup screen should appear. I use verizon and set it up as a gateway in the advanced tab and enable DHCP. I neede more ports so I thew an old 3com hub on top, it all works.
