dbags- Just to be clear for you: 1. Right now your DSL goes from the wall to the DSL modem to your computer. 2. You will now modify the system by unplugging the cat5 cable from the back of your computer, and plugging it into the Linksys router; then you have a second cat5 cable that will go from the Linksys to the back of the existing computer. All you're doing is inserting the Linksys router so that it can take the signal from the DSL modem and split it up to more than one computer. All this should be very clearly described in the Linksys instructions, including the step-by-step sequence of installing the new router software and making the physical conections. Once this is completed, you will have the capability to connect up several more computers with cat5 cable and/or several wirelessly as well.

Yes you absolutely can still connect the pc by use of the ethernet cable from the router and use the laptop wirelessly, that is how most usually do it since the desktop stays put. Mine is that way I have my router and cable modem on the end of my desk so easy access from there to my desktop computers so they are all connected by wire, my netbook and laptop are wireless, but even they can be connected by the ethernet cable should you need to. Before I had my wireless router I had a 25ft ethernet cable that ran from my desk on the baseboard to my recliner where I use my netbook. I buy a lot of my electronics from newegg and they do offer good prices and quick shipping. I also use buy.com quite a bit. You may want to check some of those in comparison to your local store. Also if you have a walmart check there they usually carry these kinds of items and for less. I got my wireless linksys router there. On the usb cards some come with a cord on them so the usb device can be moved around some on the desk which will help with reception sometimes. feel free to ask all you need we will try to answer. I too prefer to buy the same brands when possible it just helps sometimes for compatibility issues.

I have enjoyed the disucssions here. I am on the quest to find what I will be able to do in my new RV. The main issue will of course be first getting a wifi signal from something. I do have an ATT air card which has a 5GB cap, I have my cell phone but have the minimum data plan on it currently and they do not offer an unlimited. I have a zyxel portable router that can make a hotspot from a wifi signal. 11n-compatible Wi-Fi router supports DSL/Cable and 3G connectivity, and a unique failover capability; should your wired connection be interrupted for any reason, the MWR222 will automatically switch to a 3G/4G wireless signal via the users Mobile Broadband Adapter modem. So now I have the ability to have enough wifi in the RV to use any of the devices I want to use. but I need to search out other cheap(ha!) sources to obtain an internet signal on the road. I know some places we will stay do provide free wifi and using my own portable router will make that wifi secure, but for those places out in the boondocks that don't provide wifi, I will need some kind of access. My ATT air card at 5GB cap sure won't allow much streaming of anything. Any thoughts? I have been looking at Roku and other boxes and with the usb port I definitely could download plenty of my own content to have available to view for the times I am not able to gain decent access to anything. The RV does have a roof top antenna and it is wired for cable for when we are at a site with cable. I do have direct tv at home and I know they do offer an on the road version to be able to use you current direct tv account with RV direct tv equipment, no idea of additional costs. the zyxel I have MWR222

Everything will work like you expect. With possibly the exception of the 2.4ghz keyboard, I dunno. Seems sometimes that can cause problems for some with the router, sometimes not. So it may affect your whole home network. I had a 2.4 cordless phone that worked great with my wifi, but occasionally my connection would get stuck and a reboot of the router would fix it. Only used that phone a couple of months and thats the only time period the router had to be rebooted occasionally. So it more than likely was the problem. Suprised your modem isnt already a router/modem. Might ask comcast if you can buy one from them,, most isp's have special pricing for customers. Usually cheap!
