> Can we simply buy a wireless access point and plug it into the LAN
Yes, it's as simple as that.
As for recommendations, I've used D-Link and 3COM with success.
The signal strength will be affected by the internal walls so you may
have to move the AP or the laptop(s) depending on the signal strength.
You may wish to try connecting two of your laptops (that already
have WiFi cards) - one from the position where you intend placing the AP
and the other in various locations around the house to test the signal.
You may wish to do this BEFORE you buy the AP as, if the internal walls
are foil-backed, you may have serious signal problems.
Also, as you've already got WiFi cards for the laptops, make sure that
the AP is compatible (I don't know how backward-compatible the newer APs
are, eg 802.11g/a).
Now tot along to www.irishwan.org and see what they're all about.
