Topic: I'm doomed with wi-fi :(

[Ghisy]

Hey guys,

I bought this USB adapter that actually creates an access point on your home PC using your existing Internet connection.
I thought it was a pretty neat alternative to a wi-fi router.
Well, I can't seem to make it work. I've been emailing Hercules' support and they're actually really nice but after doing everything they told me to, my laptop (this is what I've been using to test the connection) can see the wireless network, can connect to it but I still get no internet on it.
It's like a "ghost connection" and it's really really weird...
So yeah, I'm very unlucky with wireless:
- first, I get the Nintendo wi-fi adapter and it turns out it's imcompatible with my firewall (ZoneAlarm),
- now this.
This sucks

ps: the USB wi-fi transmitter I got is this one
