I have to put an antenna on my computer so my wife can use her laptop and my other computer that I am stting up for the kids will work. I have a dell and was wondering what the best ones were. I have to go about 100ft in range. Any suggestions? The cable company will not give me another modem and they suggested wireless. My main computer is setup for it.

THIS Router should set you up for all your wireless / wifi needs LH.

So that sends the signal, do I need a reciever for my older computer if it does not have one?

Grab yourself one of these and you should be good to go on any computer without wifi capabilities. In fact, buy a few so you have one for each computer without wifi. Dylan hooked me up with some last year when I had to do some tweaking on Matt's laptop for work that had no wifi at all.

100ft is actually a pretty good distance to have to go with Wifi, also the number of walls between the computers location and their density play into quality of signal. I would suggest a wireless router that has physical directional antenna's to give you best signal, this is the router I use and I can get my signal clearly about 300 feet away when I do wifi on my cellphone. I get that distance because the walls in my house are kinda thin but a better built house that signal would be reduced to around 100 feet, thats why the distance you want to cover signal amplification could be important.

This is my router to give you an idea of the antenna setup I am referring to there are better routers out there for the money. http://www.newegg.com/Product/Product.as...33-704-038
As far as transmitters on the computer/laptop end it is not as important the button style usb transmitters like twitch posted work well, there are alot of options on that end of it.

In theory Wireless G should cover 450' Indoors... however, practice rarely matches with theory. That said, I'm still using Wireless G at my place and it covers around 380' in all directions, so... yeah. Depends on materiel in your walls of course. Another thing to consider is that Wireless N isn't that much more than Wireless G these days, so you may as well get an N router (it is backwards compatible with G, and often with A and B also...) that will suit your needs.

Things to consider:
1. Your current computer can continue to be connected how it is now. When you get your WiFi router you will unplug the ethernet cable from your computer and plug it into the "Internet" port on the router. Then the new cable that came with the router will plug into one of the ethernet ports on the router and then into your computer:
Modem------Router------PC
2. Laptops all have wireles cards built in these days. Otherwise Twitch linked to a great USB card if you need it.
3. Most routers have 4 ethernet ports, so if your childrens' PC will be in the same room, you can probably just buy an Ethernet cable... depending on locations of course.
4. Try and get a router that is compatible with DD-WRT, as that is a firmware replacement that gives you far more control over your device than any stock firmware out there. This is a list of supported devices. I recommend getting a Belkin, Netgear or Cisco (not Cisco Linksys aka Linksys... man have they gone down the toilet) or even the TP-Link brand that Anthony is using.
5. If you can't or wont use DD-WRT for some reason (like fear of flashing custom firmware) then get Belkin or Netgear.
6. If you need help/have questions... ASK!

Take a look around.
There are a good selection of wi-fi routers out there these days. Like Ral said, Belkin and Netgear make some really good units for not lots of money. Let me add D-link to that list.

Doh! How did I miss D-Link
Too many things running through my mind I guess. Yes, D-Link is great. I have several pieces of D-Link equipment in my inventory... my favorite being my Wireless USB Print Server Which would benefit Twitch if its compatible with her equipment Bastards are expensive though, I can't believe they still retail over $100!

Course, eBay has used ones around $20:

Still, I'm not sure if it supports stand-alone scanners or not. I never had any trouble with the 2 multi-function printers I had on mine though... so meh...

I managed the scanner on the shelf. Just have to screw the shelf down to make sure it's safe is all. I just was trying to avoid holes in all the nice staining I did.
