I get the internet from the university. The problem is that there is no network in my room. The only place where I can use the internet is the garden. And since it's like 15 meters away from my room. Right now I have 3 cables TL-ANT24EC5S which are described as 'low-loss', they seem to work well.
I have 2 antennas:
- TP-Link TL-ANT2405C 2.4GHz 5dbi Indoor Omni-Directional Antenna
- 25dBi 2.4GHz 802.11b/g Wifi Yagi Antenna RP-SMA
The TP-Link antenna sees many networks including the one I want to use, but the signal is weak and I believe it's the reason why I can't connect to it.
The other antenna is an ebay-china-£7 antenna. Even though it is directional and states to have 25dBi, it sees less networks and shows weaker signal - no matter where I point it.
1. Is it possible that my network-card in the desktop pc makes some problems? Or as long as the sockets are right it doesn't really matter?
2. What antenna shall I get to make that work? What wifi antennas are used in netbooks/laptops? Could I get a similar technology?
ps. Each laptop/netbook is able to connect to the network in the garden,
As for using the china-made omni-directional antennas, I would avoid them. I've tried them out myself, and performance with them is rather disappointing. A good rule of thumb is to stick with name brand antennas. They might be more expensive, but they offer the performance they claim (most of the time).
Ubiquiti AirGrid "dish" form factor grid antenna. It's single polarity so you can tilt it to get best signal from AP and best rejection from other APs. Plug it into you laptop's LAN port or another low power wireless router in your room.
