Best way to check if router is causing connection problems?

[Colrenea]

I have a D-Link DI-704 router hooked up to 2 WinXP machines with a cable modem. I am having pretty bad connection problems when surfing, packet loss and such. I know this question has been asked and answered 100's of times, but I was wondering what the best way to test if the router is causing the problem without bypassing it. Downloading is always fine, the problems only occur when surfing.
Thanks

The best way IS to take the router out of the loop and see if you still have problems.

Why is it you can't or don't wanna "bypass" the router?

What is your functional experience of bad connection?

Packet lose is technical issue that does not mean that your Internet connection is not functional.

Frankly, I'd be looking for issues with the ISP connection, this is unlikely to be the router. As mentioned, it's easy to connect direct and eliminate the router...

I have a cable connectiom also and when I first set everything up, I assigned ip address. It worked good at first but after a week or so webpages were not loading all way, sometimes stoppping when the webpage was only half loaded. I called out the cable company and they had to replace the cable modem because I assigned ip's not having them on auto, wacked out the cable modem. When I setup the new cable modem I put everything on auto, ip dns, everything has worked since then.

First though just plug each pc directly into the modem, if one works fine and the other does not then you know it is that pc. If neither work good you know it is the modem, if both work good then you know it si the router.

Do what everyone else says first before you continue -- hook up directly to the internet w/one of the computers.

Make sure you restart the computer when you hook it up to the cable modem. Good luck.

It's hard to tell if it's any better without the router. Some pages still load slowly, but it has always been erratic. I tried lowering the MTU on my router and that seemed to help last night, but tonight it's slow again. Of course, now I can't access the web interface on my router, so I'm probably going to need to reset it. My other pc is so slow, I can't get any indications one way or the other on that one. Hopefully, it's not the modem. It's not under warranty anymore, and I really don't want to buy another one right now. It's a Toshiba PCX2000.

I'd think the modem would either work, or fail. I still suspect the ISP's connection or your wiring coming to the cable modem...

The phenomenon is typical to a Modem that starts to fail. You should try another Modem.

I've had issues with the connection several times on my cable broadband, and it's never been the modem, still using the same old Toshiba. If I were betting on an ISP issue vs. a broken modem, I'd have to lean toward the ISP being the problem...
