Wireless adapter adviceFollow

I am going to be getting a laptop soon and would like some adivce or suggestions on a wireless adapter. I am in dorms at uni and have a great deal of trouble connecting to the wireless network with my PC. I got an anntena from a friend that allows me to get a very low signal, but a signal none the less.

I am under the impression I will have a much more difficult time getting a connection with a laptops wireless card and have been advised to look into a good usb wireless adapter. Can anyone give me any suggestions on an adapter that would give me a good signal over a long-ish range. Or could someone give me an idea of the sort of things I should be looking for? As in dBi and frequncey? Is higher better? I am looking about and doing some reading but am finding it hard to get any concrete information and, frankly, I am a little confused.

Money isn't a huge problem as I will be getting it at the same time as my laptop so I have a decent bit saved, I would realisticlly be willing to spend about £100 but could be convinced to spend more if it would be worth it.

Thanks for any assistance!

Most (if not all) modern laptops come with a built in wireless network adapter, so you shouldn't need an external adapter.

What you linked is a wireless access point which is meant to be connected to the network, not your laptop. You might be able to get it to work, but would likely need access to the network's configuration settings. Also if you do manage to get it to work, the network techs are likely going to see it as a rogue AP and block it.

If you're having problems connecting to the Uni's wireless network because of a weak signal, you would probably have to talk to the Uni about it. They may be able to turn up the output of the transmitter or add another one.

Yea, it'll connect to a computer. I didn't mean to imply that it wouldn't. But it's a wireless access point, which is different from a typical wireless receiver. Although I did look through the manual and it can be set to connect to an existing network as a receiver, so you should be good.
