Well, it could be. Perhaps there are better however. First is the decision to go wired or wireless. Wired is cheaper but has some drawbacks. Are the PCs in close proximity to each other? If so, and they have built in ethernet (as most newer ones do) then it is possible that you could connect them with a cheap crossover cable.... But to offer any real advice, you need to tell us more. What operating system are you running? Is it Windows XP? Are the PCs close enough together to be able to run a wire between them? Are there more than two? Do the PCs have ethernet on the motherboard already?

In the end, you may need to buy a router and a wireless card but that is the most expensive way to start (nothing wrong with that if you want to spend the money... it is a flexible solution.). Let us know more and we will try to help.

You should be able to get away with an inexpensive cable/dsl router then. Take a look at http://www.linksys.com. In particular, check out the BEFSR41. Click on the user manual on that page and you can see how it would be set up. You should be able to find it for around $56 or even less (I have seen internet prices as low as about $40 for it). You connect the router to the ethernet port on your DSL modem and then each PC connects to the router through an ethernet cable.

The suggestion Mr. Bell gave will of course work if both PCs have Ethernet ports. I am assuming the first one does because it is already connected. With Mr. Bell's suggestion, you will have the flexibility to add two additional PCs (up to 4 total) but they will have to be wired to the router via Ethernet cables.

If you expect to want to add additional computers within a hundred feet or so and do not expect to be able to, or want to, string the Ethernet cables (Cat-5) (or USB) to them, then you should consider buying a wireless router. The wireless routers cost a bit more but allow you to hardwire in computers as suggested above and also allow you to use wireless cards in other computers to connect as well. e.g. laptops.

I have used Linksys and Netgear with good results on both wired and wireless. The Linksys equivalent of Mr. Bells suggestion is a WRT54G Obviously there are other manufacturers. I like Netgear a bit better myself because I think they look better and both function flawlessly. The new netgear box is RangeMax 240 Like Linksys, they have several at different prices; I recommend that you stay with "G" (802.11g) in any case for security and that you follow the instructions and implement WEP (Wired Equivalent Privacy) at a minimum.

Let us know if we can help and Good Luck.
