Initial setup issues: no internet, but I'm online?

[Tegila]

So I decided to setup my server on a gaming netbook (alienware 11x whatever. plenty specs for the half dozen max players) with 7HP, 64 instead of having it share with my mediaserver.

Start the install this afternoon, at first it wouldn't do anything because I had no internet...but I did it was just dialup speed. So, I tethered to my phone to use 3g and it started going fine.

After about an hour, it disconnected, and allowed me to relaunch the installer and it continued where it left off.

AFK a couple hours, see it's frozen on same thing was doing before (one of the "this may take a few minutes" lines), and I see regular ISP has started to speed up for the night, so I swap networks. Nothing changes.

I close the window, try running the installer again, and I keep getting some error, likely because it was again saying I have no internet connection, but I could connect no problem to sites.

So, I turn off my firewall and try again, same errors.

So I delete everything in the folder and uninstall everything it DID succeed in earlier and try starting from scratch with a reboot etc. Still saying I have no internet connection, but I can connect just fine. Firewall's off so that's not an issue.

I then tried reconnecting to my phone tether in case it's my ISP or router for some reason, and still can't get the isntall going again because it says I have no internet connection. The problem was there on first attempt, but fixed on second and continued fixed on relaunch even, but then it was back and I can't fix it again.

Any ideas?
