[QUOTE] I'll take your word for it but I'd only expect it to be a big problem if the cinder block walls were damp. In my village there are way more SSIDs than there are houses thanks to BTFON and other parasitic offerings sat on numpties routers. I have persuaded neighbours to use a sequential pattern of channels so there is a decent distance between all those on the same channel.[/QUOTE] That's a good plan if you can get the agreement, and there's enough trust between neighbours for the knowledgeable to assist in changing the channels used by the less knowledgeable. It might even be a plan for there to be a more centralised way of allocating channels, like there is for phases on the electricity supply. Not that I can see that ever happening though.[QUOTE] When we started out every BT router was hogging channel 11 and the folk in the middle of hte village were seeing bad congestion issues. Easily fixed by changing to a simple pattern of cooperative frequency allocation. Or move up to the uncongested 5GHz band which is still fairly uncluttered. You can do it but it is overkill unless you spend all your time copying large disks across the network as your main pastime.[/QUOTE] Or use a server or NAS for locally stored files or backups.[QUOTE] I don't disagree that performance wise wired will win, but provided the Wifi is fast enough for all reasonable uses it is a *lot* easier. In a heavily congested area there might be a problem but installing vast lengths of hidden cat5 or cat6 cabling isn't my idea of fun. I have done it too many times in the past and view Wifi as plenty good enough for most consumer use - even for video streaming.[/QUOTE] That's fine until a few years time when everyone wants to stream 4K3D, or whatever the Next Big Thing in video turns out to be. I've yet to see data bandwidth requirements reduce for anything, so if you plan for even the fairly short term future, you need to take account of rising demands and expectations. For me, flood wired ethernet (cat6) is what should be normal NOW, and if you want to provide any kind of future proofing, then it needs to be trunking. How many years do you give it before even domestic networks are moving over to fibre? That move started in business networks about 15 years ago - I know because I was installing them! OK, copper got faster, so the change hasn't even completed in business yet, but it'll come, and domestic will follow, once mass use in business pushes the costs down.
