Using public access network - SLOOWWW

Okay, so I'm staying at this crappy hotel for the next 2 months while on a job. I brought my desktop PC thinking their would be an ethernet port in the room but there isn't. I went out and bought a Belkin USB Wireless N150 network adapter and I download things at roughly 25kbps which just... sucks. I tried to ask the "tech guy" here what type of router they are using and he said "W-E-P" so I just said "okay" and walked away knowing that he barely speaks english. What can I do to get any more speed out of this? I don't know if it's a B, G, or N. If it's a G, would buying the N300 (i think it's "N+") or the N600 Dual Band help at all? What settings can I change? What can I buy?

I've also got my Xbox 360 hooked into my PC via the ethernet port and shared the network connection with it to play Xbox Live, it's slow, but not unplayable. Any advice on getting better speed here would be appreciated, although I'm pretty sure anything that would help would be answered to my first paragraph.

If the people will let me have access to the router (apparently, I'm the only one that has even asked to see if they have wifi, this place is practically a ghost town) what can I do then?

MY PC SPECS:

3.2 intel core 2 duo (conroe)
asus p5q mobo
4gigs kingston
Windows Vista 64bit Ultimate

 

In my experience, even the "we're quite expensive and we still charge you 25$ for internet every night" hotels have crappy, slow internet. I would buy a 3G USB modem instead and try and expense it. Hotel internet suuuucks.
