I've been asked to look into the setup of a wireless network used by a number of houses in a rural connection.
Due to the scant availability of broadband they have setup a system of wireless access points to share internet connections amongst several homes.
At present all access points are on the same subnet. (192.168.1.x) There is a router in each house whose WAN interface is on the 192.168.1.x subnet. As all APs and routers (WAN) are onthe same subnet it would only take one bad host to cause problems for the whole network. I have attached a basic diagram of the network.
They are experiencing reliability problems particularly in homes that have to traverse a number of access points to reach the broadband line.
This is very much a DIY network and I'm interested how this could have been architected. They have some money to replace the existing equipment (non-cisco) if it will address the issues.
Can anyone offer any advice on what they would recommend to improve reliability? Thanks for any help with this
