Dacrunk, Have You Temporarily Disabled The Wireless?
by Grif Thomas Forum moderator / March 25, 2006 3:14 AM PST

The computer can only connect with ONE connection at a time, either wireless or wired. Access the wireless connection settings on your computer and remove the adapter's connection to the router. It should then be able to connect to the wired connection automatically when you open your browser. The wireless adapter will continue to ask you about the connection, but simply deny the access.

Hope this helps.

still not working
by dacrunkpinoy / March 25, 2006 3:36 AM PST

i disabled the wireless and unplugged the connection to the router. i reconnected the cable and after a while it said that i have limited or no connectivity. i tried clicking repair and it said that it couldn't "renew the ip address."

are there any other possible solutions?

More Questions...
by Grif Thomas Forum moderator / March 25, 2006 3:59 AM PST
In reply to: still not working

Have you used the ethernet port on your laptop before and has worked correctly in other locations?

Have you tried temporarily disabling all software firewalls on the laptop?

On the back side of the DI-624 are four jacks, side by side, that will accept LAN ethernet cables. (There are actually five jacks but one is for the ethernet cable directly from your modem's WAN cable.) Have you tried plugging the ethernet cable into a different jack on the back side?

Have you tried updating the ethernet card's driver?

Hope this helps and let us know more.

yes i have used the ethernet port before. i used it when i went on a trip to orlando and then another time at my friend's house. it worked fine. i even plugged it in directly from my cable modem and it says the same thing. i disabled the firewall and still nothing also.

if it is indeed the ethernet card's driver, which is unlikely since it worked at other locations, where can i update it?

any other suggestions would be appreciated

Update It At The Manufacturer's Website..
by Grif Thomas Forum moderator / March 25, 2006 6:57 AM PST
In reply to: nope

First, visit the computer manufacturer's website, type in the model number and check for ethernet card drivers.

If there are none there, then you'll need to find the ethernet card's manufacturer and visit their site to find a driver. To find the ethernet card's manufacturer, you'll need to check in Device Manager. On Windows XP, RIGHT click on "My Computer", choose "Properties", then select the "Hardware" tab, then the "Device Manger" button. When that opens, click on the + sign next to "Network Adapters" and look for the ethernet device listed. You should have two listings. One for a wireless adapter and one for the "Fast Ethernet". RIGHT click on the ethernet device listing, choose "Properties", then click on the "Driver" tab. When that opens, write down the exact DEvice Name, the "Manufacturer/Provider" name, the driver version, and the driver date.

With that information in hand, you should be able to visit the manufacturer's website and download updated drivers, then install them.

Hope this helps.

still nothing

i updated the driver and still got nothing. does it maybe have something to do with the ethernet cable itself? it is a category 6 500MHz patch cord.

Easy To Check..
by Grif Thomas Forum moderator / March 26, 2006 8:57 AM PST
In reply to: still nothing

Borrow someone else's cable and give it a try..

CAT 5/6 cable should work though UNLESS you've mistakenly purchased a "Cross-Over" cable which reverses the connectors at each end. A "Cross-Over" cable is used for connecting computer to computer and NOT computer to modem/router.

I generally use CAT5 cables which are 350 MBHZ cables simply because they are cheaper and work fine but your cable should work fine assuming it's actually a patch cable.

Hope this helps.

Please Explain 'Other Computer Works Fine'
by Grif Thomas Forum moderator / March 29, 2006 2:11 AM PST
In reply to: nope

You've got another computer that's hooked up to this same network and it works fine? Only the laptop won't work? If another computer is plugged directly into the router and it works fine, then there's no problem with the router..

Please explain how all of this is connected. A correct network setup should have a cable from the wall to the modem, then from the modem to the router, then a cable from the router to each computer. Is that how your's is set up?

Hope this helps and let us know more.

that is correct in how my network is set is confusing since the other computer has no problems with connecting...

to clarify...wall plugs into modem, modem plugs into router, and router connects to computer 1, computer 2 connects through wireless (but i barely use it so it stays off most of the time), and my laptop connects through wireless (but cannot connect directly from the router)

Then The Laptop Is Where The Problem Lies
by Grif Thomas Forum moderator / March 30, 2006 8:39 AM PST
In reply to: correct

...The router works for one wired computer and two wireless computers. The router is working exactly as designed. If the laptop is the only one that won't connect "wired" and since you've already checked the cable by swapping with the "good" computer, then there's only one remaining culprit. It's an issue with the laptop and it's probably the ethernet card.

Just some more thoughts:

1. At this point, make sure to leave all Firewalls turned off on the computer until you get things connected.

2. On most laptops, there is a button that turns the wireless adapter on and off. (It's a samll button that has a picture of an antenna with radio waves radiating from it.) Does the wired connection work if you turn the wireless adapter OFF?

3. Because it could be a Winsocks issue, please download and run the WinsockXPFix utility from the link below:

Hope this helps and let us know how it goes.
