I have a little problem with using my internet connection through my wireless router.

The router itself is a D-Link, and for the past two weeks has been working fine.

Last night, the internet connection stopped working on this computer. (This computer is the one directly connected to the internet)
The connection continued fine on the wireless computer until the computer was turned off for the night.

I have re-wired my connection through the normal, non-wireless router I had been using before. But this is very inconvinient, as I need the internet in that other room.

The problem is, when I plug everything into the router the way it is supposed to be, I get the 'limited or no connectivity error', the IP sets itself to the default 169.244.XXX.XXX and the computer loses the connection all together.

I've tried reseting the router and plugging it in properly, then re-configuring it... but I can't get into the configuration for it even when I should be able to.

Little confusing how you wrote the problem, but I'm thinking, long story short, you're no longer getting an IP address when using your wireless router.

There are actually two steps to troubleshooting a wireless problem...first you have to determine if you are even connecting to the wireless router.

I.e. you mentioned that you're getting 169.blah.blah.blah but assuming you used the RUN..cmd...ipconfig/all command did you get D-Link info or did it say "media disconnect". If you got D-Link info move to step two troubleshooting...if you got "media disconnect" you have to figure out why your wireless connection to the router isn't working...

Step two troubleshooting...what is providing your IP addressing? Is it DHCP from the router? Have you checked to make sure it's still configured...or it could be your wireless card in your PC has gone squirelly...it's too hard to say with the limited info...but it should start pointing you in the right direction on what to check on.

Yes, I'm sorry but I'm not exactly the best with providing good information when it comes to these problems.

The main problem I am having is with the physical connection to the host computer. (The wireless is down too, of course. But I need to tackle this at first) It's no longer working, even though everything is set up the way it should be.

I also can't configure the router anymore, which I assume isn't a good sign. I've tried reconnecting everything, and reseting the router too.

Is there any other information besides the stuff from the run/cmd that could be helpful? If so, I can get that too.

Hi,
Just like dknowledge said, this is a bit confusing but I think I will also try to help. 1st of course is one question that having a router, why is your computer still Directly connected to internet? Once you have a router, I would surely connect the router to internet and share the connection and my network as I do. Your computer's IP 169.244.XXX.XXX surely states that you are not getting an IP from router, so not going more into detail and assuming that you have allready checked as much as you could and should be sufficient for the time being once your router is not configurable anymore and you have had enough with all different commands etc, why not you just PUSH THE BUTTON and reset the router? It will at least allow you to re-configure the router. We can not blame the cable here as the wireless is also not working. So either after reseting the router it should work or be Configurable. Otherwise I think you can check the warranty once it is new.
In case you don't know how to reset the router, you can check behind it or under it there will be one small button named as Reset. You got to press it for normally 3 seconds. In case you have the manual of your router, then have a look there is well.
I really hope that it will help, in case it doesn't, then Please provide more detail of the problem like about network and internet connection. Don't think that even that is hard to explain.
Good Luck

LINUX is basically a simple Operating System, but you have to be a genius to understand the simplicity!

Sounds like your router went south, as they sometimes do, but go through the steps first.

- Check your cables to make sure they're connected snugly. Reinstall your wireless adapter card's drivers. Disable your XP firewall on your PC if it's set; you don't need it with a router. See if that clears up the problem.

- Connect directly to the router via an Ethernet port and pull up its web configuration screen. You'll need the userid and password for this. See if your router is getting an IP address from your ISP. If not, check the cable between the router and modem to make sure it's connected properly then re-run the Setup Wizard.

If you can't connect to the router's web site check your PC's TCP/IP settings to make sure you're properly configured ("assign IP Address automatically" and "Use DHCP server for WINS resolution") then press the router's reset button if you still can't connect. If you still can't the router has probably gone bad; return it for a replacement and try again.

- Once you're able to connect directly to the router make sure that the DHCP server is enabled and the Wireless adapter is turned on. If you've enabled encryption clear it for the moment; you can set it later. Note the SSID (you should change this from the default to something like "MATILDA1" or the like), channel, and the MODE setting.

- Disconnect your PC from the ethernet connection, go into Hardware Configuration, and disable the Ethernet network adapter. Not the wireless adapter; you'll need that. Sometimes the PC gets confused about which adapter it should use to connect and unless you're going to go Ethernet again you don't need the Ethernet adapter enabled. If you ever do it's easy enough to re-enable it.

- Run the wireless setup wizard and input the SSID, channel, and mode you're using for this connection. The wizard should display the connection, pick this and set "Automatically reconnect to this network when in range".

- Now go into the router's setup screen and enable encryption. If you're using WPA encryption enter a passcode; if you're using WEP *directly enter the 16- or 24-hexdecimal character encryption key you want to use*. There are websites that will automatically generate a random key for you or you can work one out for yourself. Reboot the router and after it's rebooted rerun the wireless setup wizard and input the encryption key (WEP) or passcode (WPA) you selected for this connection.

The WEP standard was a little squirrelly about its passcode implementation: If your router and wireless network card are by different manufacturers the same WEP passcode may not generate the same encryption key. WPA shouldn't have this problem.

Thanks for the replies, but I think I've determined the router's just gone bad. I'm going to try tech-support on my day off, but I think I'll have to just get a replacement.

I'm going to try tech-support later, and if that fails I'm going to try and get it replaced.
