Sharing 1 Network Adapter between 2 computers!

So I just got a second computer that needs internet. I'm wondering if there's a way to use the D-link USB Network Adapter that I am currently using on my first computer.

Here are the relevant details (or at least what I think is relevant)
Computer 1.
Intel(R) Pentium 4 CPU 2.80GHz, 2.79GHz,
1.00 GB of RAM
Microsoft Windows XP, Home Edition (Version 2002) Service Pack 2

Computer 2
Intel(R) Celeron(R) CPU 2.80GHz, 2.79GHz
504 MB of RAM
Microsoft Windows XP, Home Edition (Version 2002) Service Pack 2

D-LINK Wireless N USB Adapter - (DWA- 130)
Manufacturer: D-Link
Part Number: DWA - 130
Interface(BUS) Type: Hi-Speed USB
Form Factor: External
Antenna: Internal Integrated

Data Link Protocol: IEEE 802.11b , IEEE 802.11g , IEEE 802.11n (Draft)
Frequency Bandwidth: 2.4 Ghz

This is what it looks like:

I hope this is enough information for you to understand what I'm trying to do.

Finally, I'm guessing that the easiest thing to do might be to grab another Adapter for the new computer. But, I figured I'd attempt to see if there was a way to share the one I have.

Any advice would be greatly appreciated.

Cool, I actually bought the exact same wireless adapter as a Father's Day gift to my Dad 2 or so years ago! I got a pretty good price match, Staples had it on for something like $39 for some strange reason, so when I saw it at Best Buy for $79 I said, wait a second - The Staples was too doors down but had closed, but I'd taken a picture of the exact same item at the other store - so they did the match and I got it for something like $35+tax.

Well you have some options - you can't just hook it to both computers via a USB hub if that's what you're thinking.

You could use an Ethernet hub or an Ethernet Crossover cable to link the Ethernet ports on both computers (most computers have them built in, if not connected via PCI). You could then set up an ICS - it's tricky though and can be a bit difficult and slow.

Or you could also just get another PCI Wireless Adapter - there are many out there and they are pretty cheap. I'd recommend getting a USB one though - I've been able to get a weak signal many times by setting up the wireless adapter in weird positions on the wall connected via a USB extension cable. It's not nearly as convenient or easy to do with a PCI one since it's internal - you can adjust the antenna it's true, but some USB adapters came with antennas as well - such as my TP-Link TL-WN722N 150Mbps High Gain Wireless USB Adapter for example.

Probably the best option would be to get a cheap USB adapter for the other computer as well - you can find them for as little as $10 now days from local retailers - even DealExtreme hasn't gotten that cheap yet from what I've seen.

For example CTY has this: Linksys WUSB54GC-RM 54Mb 802.11G Wireless USB LAN Adapter (Certified refurb by Linksys) for $10 on special

I'd also consider this super cheap  TP-Link 150Mbps Wireless Lite-N USB Adapter (TL-WN721N) for $14.99 brand new, regular price

I prefer N to G, but it depends on what you want.

I hope that helps ,

Thanks PJPeter for your recommendations.

After posting this message, I actually considered the PCI Wireless Adapter option and you are totally right. The Mobility of the External Adapter comes in very handy From time to time (See.... I live in a basement room. You can probably figure out the challenges I might have).

On one hand, I have this desire to experiment with the Ethernet Crossover Cable idea you suggested (just for the fun of it), but on the other, I think It might be way more effort than I need to exert in light of the USB Adapter deals your mentioned.

I do prefer Wireless N to Wireless G as well. My brother has a Linksys Wireless G Adapter (Product Name: Linksys WUSB54GSC Compact Wireless-G USB Network Adapter) that's been working well for him. Now I just have to figure out what the difference between the Linksys WUSB54GSC and the Linksys WUSB54GC is (if any). I'll have to do that before I head out to grab the Adapter (If I choose to go for the G instead of the N).

The TP-Link adapter you've suggested is an N so it's very appealing. The only reservation I have is that I have no idea how reliable "TP - link " is.

One thing that's certain is that I'll have to do a little more research.

Thanks again for your suggestions...!!!

Technically I have that TP-Link but I bought it to use as my extended adapter while on vacation - and unfortunately I haven't gone on vacation yet so I haven't tried it. I found in Greece as well as in Newfoundland though that if I place the antenna in just the right spot I can get a free signal or two - but it's hit or miss. Definitely being able to place the adapter anywhere helps though.

There are other options out there I'm sure - but in terms of cost and convenience these are probably the best.

Wish I could say for sure on the TP-Link, but all the reviews I've read have been good - but I haven't read too many. They are pretty cheap and seem to work ok - but definitely do some more reading and do post again to let us know what you do in the end .
