Wireless building to building

I need to (cheaply) wirelessly link buildings seperated by a single road, probably about 20 m away from each other.  I've tested with an 802.11g wireless point in the building on one side and my laptop in the building on the other and I get full signal strength.

One building has the complete LAN, the other building will just need to provide support for about 4 PCs on the same LAN to allow access to the file servers and the internet.

Is it possible for me to simply join to wireless access points, for example the Netgear WG102, or would you suggest something else.  I've been reading up on the web, but am getting confused.

A quick answer is greatly appreciated.  Thanks in advance.

you can go 2 ways,


1 way would be to have a wireless access point in both buildings setup in bridging mode.
the access points would both have to be hardwired to the network in each building and then you can see both networks from both locations.

2nd way would be to have 1 access point in the building where the main LAn is hard wired in to the network, the acess point in access point mode and each pc in the other buidling (about 4 i believe) to each have a wireless network card to connect to the acess point.

i dont really do prices but at a guess option 1 would be cheaper if your pc's in the office with 4 in already have network cards, you may need to just buy a switch to hardwire them all into the AP unless the AP has 4 ports (some do).

remember the security side of things, you will want to use WEP if you go to option 2 , option 1 you can specify on each access point the MAC address of the other AP connecting and therefore You wouldnt really need WEP.

hope all this helps and i have understood the question.

That was quick!  I think I prefer option 1, as it will make it easy to add another host on the building 1 side as and when, without having to worry about another wireless card.
Is bridging mode a standard feature of all access points, or do I need to be looking at the higher end of the market?

Just looked in a standard Netgear WG602 I have, and have found that it is easy to switch it to bridging mode, so thanks for your help.
