anyone on here that can do this for me,router is in top bedroom
cable needs to go to one up stairs bedroom and two lounges

Have you considered Powerline adaptors?

Why bother? Many routers have wi-fi built in, so if the equipment in the other bedrooms can accept it then you can save yourself a lot of hassle.

Alternatively, use the existing mains wiring. There are plenty of products that will do this for your without the cost of cables not to mention tearing up floorboard and drilling holes through walls. (e.g. http://uk.tp-link.com/) you need one for your router and one for every other user/printer etc.

I have several computers and tablets and phones and printers and scanners and they can all intercommunicate over the router's wi-fi with not a single ethernet cable anywhere!

part of the house is an extension,rsjs ect?

part of my house is on a different ring main?

As long as they go to the same meter, you'll be OK. I have two rings and they worked fine before I dumped them when wireless came in.

I use power-line adaptors here, they work exceedingly well. I highly recommend the TP-Link make, mine are the AV500 nano ones. I have four of them bought as two pairs (starter kits). I think I bought them from Tesco on Ebay.

Wi-fi doesn't handle large number of users, if a few neighbours are heavy wi-fi users or you have a number of users in your household, as soon as you wander away from your router you start having problems.

I use wi-fi as well for phones and laptops.

I think there's likely something wrong with your wifi diggindeeper. The first one Virgin supplied wasn't all that good. There was one bedroom in which it didn't work, but the present one seems to work everywhere. This is in a solid four bedreoom victorian terrace with the neighbours using wi-fi too. You just have to choose a channel that the others are not using. We have agreed with our neighbours how to allocate the available channels so as to minimise any interference between us. We have used powerline adapters in our house at one time and they are OK, but they are a bit pricey if you have a lot of things wanting to use them. The router handles 5.4GHz as well as 2.4GHz but I have not experimented with the higher frequency yet.

One of the nice things about wireless is that you can move your printer to wherever you happen to be working with a laptop or a tablet, and all you need to do is to plug it into a power socket. No mucking about with ethernet cables etc needed.

As I type here, my wife is watching a HD video stored on a network drive on the telly via the wifi which is two rooms away. I am using a desktop, and intermittently reading a book on a tablet all over wifi. It seems to work as smooth as silk.

Nah, its just like a road, too much traffic and most of it slows down, the traffic doesn't have to be coming from or to the same place as you, its the fact that its in the same place as you that slows you down.

I've been playing with radio data for many years, long before wi-fi or the internet existed, including writing and using my own protocols.

There are only 3 wi-fi channels (1, 6 and 11) and even less for wireless-n. Power line devices use hundreds of channels and uses many in parallel.

Well, my wi-fi is unaware of your arguments, and continues to work perfectly. If it didn't, I'd go back to the powerline units I have sitting in a drawer gathering dust.

I just ran an Ookla speed test on my phone and it came out at 50MB/sec as far from the router as I could get.

I am on Virgin Cable at 150MB/S so it's a third of that speed but that is plenty for what I want. It might work even faster on the 5GB band, but I can't be bothered to try it.

One point about powerline units is that you will have only one connected to your router, and that will constitute a bottleneck just as the router does for wifi. The two - wifi and powerline - are very similar in the way they work as far as the user is concerned. the only difference being that powerline is confined to the powerline, and even battery operated gadgets, therefore, need a connection to a socket. Sometimes this is not an inconvenience, but often it is. I recently bought a colour Laser for a mere £80, and wireless is built into it. It works beautifully. I doubt you'd get a pair of powerline connectors plus the cables to connect to them at that price!

It is worth considering too that wi-fi is everywhere these days. I can access my home network from the local Pub or on the bus if I want to. Not that I do very often, but I have used it in a hotel - using their free wi-fi and my tablet - to watch a movie stored at home on my NAS for instance.

You must be lucky enough not to have 17 wifi routers in range with 10 people trying to watch videos at the same time.

The joys of high density housing

The powerline units operate up to 500Mbs, the main bottleneck is the internet connection, multi users isn't a problem on them. Neither is having two separate power line networks in the same house. Neighbours don't affect them at all because when it goes through the armoured cable connection to the house the signal is killed to all intents and purposes. Flats might have some bleed to each other but with 500Mbs to play with its not normally a problem.
