Why are my wireless computers working but my computer connected to the router isn't?

Question

I have had a router installed for over two years and my two computers that are wireless work fine. The computer that is directly connected to the router will not enable me to connect to the internet. My internet service provider indicated it was due to my IP address. I've powered down my modem multiple times and still no luck. Also, the IP address starts with 169.254 which my internet provider says is the problem. FInally, I connected this computer directly to the modem and it still did not work, leading me to believe this is an IP address issue. Any suggestions?

Can you advise as to how I can check the modem to see if there are still any DHCP address left for it to hand out. Also, how to check if the DHCP server can hand out IP addresses to the wired computers, not just to the wireless computers. Thanks.

Answer 1

Check the modem to see if there are still any DHCP address left for it to hand out. Check if the DHCP server can hand out IP addresses to the wired computers, not just to the wireless computers.
Check if you can have both a wireless and a wired connection at the same time (some modems will only allow one type of connection). Check if your network card is installed properly. Check if the cable is still good, swap it with a different cable if you can.

Answer 2

If you are getting a 169.254.xxx.xxx address, that means that the router for some reason is not giving your PC an IP address.

Check the router to be sure that DHCP (that is the protocol that gives out IP addresses) is enabled, andhas a large enough range of numbers to hold all the computers connected. (You can't connect 10 PCs with a range of only 9 numbers). Reboot.

If you still do not get an IP address, you can go in and manual give the PC an IP address. Go into the Network Neighborhood and right click on your network card. Assign it an IP with the first three numbers the same the numbers in your router's address (not the ISP's modem). Subnet mask is 255.255.255.0. Default gateway should be your router's IP address. Also set the DNS server to the router's IP address.

It should work after that.

Answer 5

Make sure you are not plugging in to the WAN port. That port should connect your router to your modem.
