Hello,

I have two desktops at home and currently one laptop (though planning of adding another one to the household).
I have never hooked up a wireless router thing but I am assuming it is not that difficult.
I only have the one desktop hooked up to the internet through a comcast modem.

Can I get a router that will be able to have all computers connect to the internet?
Does it just go through my router?
Would I have to get another modem from comcast for my second desktop?

Thanks for the help!

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 thumbup.gif

I too have comcast for my ISP. Here in nw Florida comcast does not require cloning the MAC address to connect a router to your cable modem. I have hooked many people up to routers on their comcast cable modems locally and all that is required is to unplug the cable modem from power, unplug the network cable from the back of the cable modem and connect it as CaveDweeler2 suggests, connecting the plug from the back of cable modem into one of the 4 closely spaced ports on router then plug the cable that comes with most routers from the port on back of cable modem into the port on back of router that sits off by itself. Next power up the cable modem waiting about 5 minutes to ensure it has completely connected to ISP, then plug power into the router and wai for a few minutes before turning on your wired PC. I would suggest you follw CaveDweller2's suggestion and type in the IP address for router into your router (usually listed in the documentation in router box) and use the default UN & PW. Like I said you MAY not have to do the MAC address cloning depending how your local comcast office plays with others (again mine is very friendly, others may be less friendly as CaveDweller2's seems to be). I would definately set your security settings such as changing the SSID (name of router) so your wireless computers know it's your router they are seeing not another default router nearby. Change the password to get into the router configuraton pages you are currently working in so others cannot get it and lock you out of your own router. It is advisable to lock (password protect/encrypt) your network even if all you are doing is surfing the web and doing nothing sensitive so the kid nearby doesn't download kiddie porn or stolen music etc from your network so the feds show up at your house and take your systems and put you in the pokey (just a sugestion, there are many people wishing they had done this currently undersuspicion of these sorts of "crackers" (badguy hackers). I would suggest setting the encryption to WPA2 Personal if all of your wireless systems support the higher WPA2 compared to WPA or WEP. Definately use higest ALL of your wireless systems support or they cannot connect. The other PC you have can be wired into another one of the empty ports on router or you can make it wireless with USB or internal wireless cards fro desktops (USB obviously the easier choice if you have available USB ports). If you add more wired machines remember there are only 4 ports to connect so if you are going to connect more than 4 systems/wired network printer/print server/network attached storage (external hard drive made to be used between all computers on network to share storage you will want to buy a network switch that will give you more ports, which uses one of the ports on your router to make it usale by more devices, most switches come in 5/8/16/24 ports so future proofing your network is easy (I would think and 8 port switch would be more than adequate for most people. The wireless computers will be reuired to enter the password you selected to get throught the router, Wni XP & Vista only require it once as does an iPod Touch, wireless TiVo HD. I hope this helps you and anybody else, BleepingComputers has been a source of a lot of help over more than 2 years for me when playing tech on my systems and playing tech for friends and family and I feel it my responsibility to passon my experience to others as repayment to BleepingComputers for helping me.

Two desktops and two laptops is a very common home network. I'm guessing the one desktop will eventually be wired to the router. If the other desktop is to be wireless, you'll likely need to buy a wireless PCI or USB NIC, and the router. Stick to name brands with the hardware.

Most of the configuration will be done when logged in to the router. Only the SSID and WPA/WPA2 key need to be entered on each wireless device.
