 Posted: Sun Sep 05, 2010 6:42 pm Post subject: wireless internet connection question |
 |
|
I work at a university and live just outside the back gate (next door to one of the dorms). I have a university issued password for the campus-wide wireless internet, but I don't have a notebook computer. And in my apartment I don't currently have an internet connection.
Questions:
1) Could I use my desktop (in my apartment) to connect to the university wireless system? What would be needed to do so? I have never seen a desktop used with a wireless internet connection, but I have heard that it can be done.
2) If a desktop can be used, am I too far from the wireless signal? I know that there are "booster" external antennas available for computers located just outside the normal range. |

You could just stick a 15,000 won wi-fi card into your PC or just get a wi-fi dongle which connects by USB. That's what I do with one of the PC's in my house.

 There's not much chance anyone here can answer that!
The signal strength from an average wi-fi transmitter will start to weaken after about 30m as long as there's no or few obstructions. |

Wifi network cards are cheap and easy to find.
They are just as easy to install (plug and play easy).
Signal strength varies with a number of things.
Best bet is 100 meters from the router (no walls or other electrical interference (like motorcycles, electric appliances, or electric motors.
If you add in any of the above the signal strength drops off FAST.
On average 30 meters but if you add some concrete walls it can be as low as 10 meters (~30-35 feet). If there is a lot of steel in the walls or wire screens in the windows they can potentially block the signal completely.

| I sit two floors above the router in the main teachers' office, and get zero signal on my phone. So, effectively I sit less than 10 meters from the router, but don't get a signal. |

The steel in a reinforced concrete floors are effectively blocking the signal. I bet that if you had line of sight though a window you would get close to 30-40 meter range.
