I have a wireless router that is working fine with my laptop (Dell Inspiron 1100). But I can't get my my Win98 PC to connect to the Internet. The PC seems to be connected properly, but I simply can't connect to the net.

You aren't providing enough information for anybody to be able to help. There isn't any inherent reason Windows 98SE can't connect to the Internet through a wireless router. I do it all the time. The problem would most likely be in the wireless device you using to connect to the wireless router with. Win98SE support isn't the greatest on much of the newer hardware. I would suggest first trying to connect to the Internet by using a wired Ethernet connection from the Win98 machine directly to the router. Once that works, then try to sort out the wireless problem.

I'm trying to connect my Win98 wired to the router. The router is working wireless with my laptop. It's not working wired with my Win98 PC.

That's good. Connecting with wired Ethernet simplifies getting things working. You need to check the IP configuration on the Win98 computer. Win98 has a useful utility for that called Winipcfg.exe, you can access it by opening the 'Run' dialogue from the Start menu and typing in "Winipcfg" (no quotes) and press enter. When the Winipcfg dialogue opens up, you need to make sure you have the computer's Ethernet adapter selected and then look at the information about that device's IP configuration. Check that the computer has an IP address, a Subnet Mask, a Default Gateway (an IP address that should be the same as the Computer's IP address except for the numbers after the last period), and an IP address for at least one DNS Server, but there should be 2 DNS Servers. Please post this information. You should compare this information with the IP configuration of the Wireless adapter in the Dell laptop. The IP addresses for the two computer's should be different, but all the other numbers should be the same.

Win98 IP# xx.107.110.129 Win98 DG xx.107.104.1 I checked my laptop and it said my IP# is xxx.168.0.199 but this website says it's xx.107.119.101

You laptop IP address looks typical. It is what is called a NAT (Network Address Translation) address for internal IP networks. The Gatway address for your laptop is probably 192.168.0.1, which is your router's INTERNAL IP address. Please understand, there is no security issues about these internal IP addresses, there are MILLIONS of people with an router which uses the same internal IP address of 192.168.0.1. NAT addresses are "set aside" just for internal networks are are not accessible over the Internet. Your router "translates" that NAT address to the EXTERNAL or Internet address which is provided by your ISP. This website reports a different IP address because your internal IP address is not viewable from the Internet. The IP address for the Win98 machine is not correct. Go to 'Control Panel', then double click on the Icon for 'Network', then go down the list and find a line that looks something like this: TCP/IP-> (Ethernet card description) select or highlight that line and then click on 'Properties'. That should open a dialogue box of TCP/IP Properties. It should open on the IP address tab and there will be an option to "Obtain an IP address automatically". If that option is not selected, then that is your problem. Select that option, then click "Okay" which will return you to the Network dialogue. Then click 'Okay' on the Network dialogue and Windows will prompt you to restart your computer. After the computer reboots, look at the Winipcfg again and you should see an IP address which looks like: 192.168.0.* (*=a number between 2 and 254). If this is how things work, then you should be on the Internet with your Win98 computer. If not, then post what you experience.
