My laptop's internal Wi-Fi antenna is horrible. At my school especially, it can only connect half the time, and when it does, rarely actually assigns me an IP address. I'm looking for a USB adapter that can help me actually get Wi-Fi at school (and anywhere else I might need it too). I'm wary of doing this, because I already have a USB Wi-Fi dongle (Netgear wg111v3), but it's pretty much as bad as my internal one.
I have done some research, and narrowed it down to these two being best for my budget:
So my question is: Which one will give me better reception and reliability?
