Any wireless router will do. What brand and model is up to you.
With Comcast(my ISP also) the first thing you have to do is clone you MAC address to the router. When Comcast comes to install your broadband they use a PC's MAC address in combination with the modem to make your connection. So you have to make the MAC address on the router the same as that PC or it won't work. The first few steps for this will be the same no matter which router you buy but after those general steps it gets router specific.
Assuming you've bought a router, unpacked it and set it near the modem the General steps: Plug the power into the router -> The Ethernet cable running from your PC to the modem, unplug it from the modem -> plug that end of the cable into one of the router's Ethernet ports, there is normally 4 grouped together and one sorta by itself -> With the PC plugged into the router open a command prompt on the PC(in a run box type cmd and hit Enter) -> in the box that appears type ipconfig /release and hit Enter -> type ipconfig /renew and hit Enter -> If there is no error message type ipconfig /all and hit Enter -> Make note of the Default Gateway listed. -> Open a web browser -> in the address bar type in the IP address for the default gateway and hit Enter.
At this point a box should pop up asking for a user name and password. This is where it gets specific for your router. The UN and PW will be in the paperwork that came with the router. You'll generally see, in the paperwork, where it talks about entering the IP address and then below that it will have what you use for UN and PW. Enter what it says to enter and you'll be looking at the web UI for your router.
You'll have to look around for the MAC address cloning. I have a Belkin and on mine on the left side it says MAC address. I click that, a page comes up and there is a Clone button. I click it and apply changes at the bottom and done. But that is mine, the page for yours should be about the same, you just need to find it. Once you've cloned the MAC Address and saved changes, take the smallish Ethernet cable that came with the router and connect it to the modem, where you had the PC plugged in and plug the other end into the back of the router in the one port sorta off by itself. power cycle the router(unplug the power for a sec or 3 then plug it back in) And you're done. Open a browser and it should take you to your home page.
Can I get a router that will be able to have all computers connect to the internet? - Yes
Does it just go through my router? - Yes
Would I have to get another modem from comcast for my second desktop? - No
Any other PC that is going to be wired just plugs into one of the 4 grouped ports on the back router.
If you need help with the wireless part of your issue, post with the make, model and revision of the router you choose and the OS's of the computers going wireless. That way anyone helping you will know specifically just what to tell you to do inside your router. Its not difficult at all =)
Any questions about the steps above post before you unhook. If you have an issue getting it all hooked up or something doesn't go right, just unplug the cable from the router and plug it back in the modem(the one from your PC). Do the ipconfig /release - /renew thing and your connection should be back up.
Hope this helps
