About to rebuild the network here after moving house. One issue I'm contemplating is performance and redundancy. One part of the network can't (easily) be reached by Cat 5/6, running cables t that part of the house would be too messy at best. I have two ways I can bridge this gap - Powerline Ethernet adapters, which have worked extremely well in the past, or WiFi, using an access point in client bridge mode. Now the powerline adapters do work extremely well, with a rated speed of 85 Mbps. I've never had an issue, except for the switchmode supply of one laptop, which trashed the link (took a bit of detective work that one!). The biggest weakness of these devices is that they can't be battery backed up. If the mains goes down, so do they. WiFi can be backed up, especially since a lot of the gear I have will happily run off a 12V battery, and some of the systems on the far end will be running off a battery backed DC supply. However, performance with the WiFi solution isn't as good. Is there a way I can (easily and cheaply) arrange to run on the powerline devices by default and fail over to WiFi, if the power goes down? -- 73 de Tony VK3JED http://vkradio.com
