I work for a very small IT Company, in fact there is just myself and my boss!
We are new to wireless Networking and have tried setting up a small network between two small LANs.
One LAN cosnsists of around 30-40 users running off Windows Small Business Server 2003. The other LAN has around 10 users currently not on a domain.
The two locations are situated approx 200-300ft apart, separated by a street. There is one particular building on this street which slightly obscures the view from location to location.
Nevertheless, we set up 2 wireless access points from 'Buffalo' and installed antennas on the roof of each location.
However, we can only acquire intermittent signals between antennas for around 30 seconds, sometimes not at all. It is never consistent. We are using different channels on the access points and have tried variations of channels i.e. 1 & 4, 1 & 6, 2 & 7, 5 & 7 and so forth.
We have tried moving the antenna at one location so that we have line of sight between the antennas, but with no luck.
We believe all settings are as they should be on the access points. Buffalo even set some of these up for us when sending us replacement kits. We are wondering if the equipment is not up to scratch.
We don't really want to install an independent server at the smaller LAN. Also, Small Business Server does not allow communication between LANs with servers in each.
We are ruling out a VPN also as these seem inadequate for transferring large files.
Any ideas upon our best approach?
