Extending wi-fi

Yes. CAT5 rated at 100A.

The OP might not care about the radio ham next door. In fact he might
regard him as an abomination to be avoided at all costs.

I have been a licensed radio amateur since 1968: GM8BHR.

Well, at least God seemed to apply some of that to telephone cables

Please replace invalid and invalid with gmx and net to reply.

Seconded about the mains transmitted internet. I got rid of some old school
ones but in recent months some new ones have popped up that sound like a
fast ticking over car and every few seconds like a fart which is loud enough
to affect medium wave strong signals.
They do filter the ham bands but shock horror, some of us want to tune
around to other material.

as for boosters, I see BT do one, as mentioned, but one thing to bear in
mind about the radio solution is that a booster normal uses yet another
channel, and in some areas congestion and interference are so bad
connections drop out all the time.

My BT Home Hub 3 running on Infinity is downstairs in my study. The wi-fi
from that reaches all parts of the house using my DELL laptop. I take a
feed up to my TV in the drawing room on the first floor using Home Plugs
and that works well - HD transfers perfectly.

Then I bought an iPad which depends on wi-fi but cannot pick up the router
in the front part of the house and certainly not upstairs.

So I would like something to plug into a 13A socket to pick up the Home
Plug signal and broadcast that as wi-fi so I can use the iPad while
watching TV. BT sell a kit that does that for £89 - but people here may
know of a better answer. I may lay in a Cat 5 cable if it comes to that
but before I start burrowing under floors, I would welcome advice.

Those extender repeater things seem to work OK (and don't require ant
wiring).

Modern one are supposed to notch out the amateur bands - but it's not
all of the bands. And it's only a matter of time before this requirement
starts to be conveniently forgotten in the interests of increasing the
bandwidth. Also, I think there are proposals to increase the transmit
power levels, which will tend to make any notch filtering inadequate.

I might be wrong, but I think that boosters actually use the same
channel (presumably on a time-share basis?). If so, I guess this slows
things down. [Expert advice needed.]

It doesn't matter here - my next door neighbour has wi-fi which is barely
readable in my house - large stone-built houses - and the next again
neighbour is not receivable. So basically I could use all the channels.

For what it's worth, I've set up an Edimax 7228 configured as a
wireless repeater on an ADSL connection that gives a download speed of
about 11Mb/s direct. The repeater does extend the coverage area to the
back garden, which is what it was installed for, but the download
speed usually tests around 5Mb/s. I don't know if the speed reduction
is a characteristic of this particular unit or wireless repeaters in
general, as I haven't yet had the opportunity to test any others.

And does your neighbour regard you as an abomination? Do you covet his
wife, anything like that?

Yes. 1:1 time shared between source and target, so speed halved.

I think my laptop says that that it links to my wireless router at
54Mb/s, so a booster would cut this to 27Mb/s. As my internet downstream
is only 1.5Mb/s, I guess an extender wouldn't be noticed. I have
actually installed an extender (a Netgear WN3000) for a friend who lives
not far from the exchange, and whose internet speed will be far faster
than mine. There have never been any reports of speed problems.
