I have connected a wireless router to my PC in an upstairs bedroom and a usb
adaptor to a pc in a downstairs dining room. Everything appears to be set up
ok, but the downstairs pc isnt finding the wirless router. It did on one
occasion show up a very low signal then lost it again. Is there anything i
can do to fix this apart from moving pc's.

Position the antennas so that they are parallel to each other.
There is a dead spot directly above and below a vertical antenna.

Thanks for that John. Tried it, and the network did connect. It showed a link
of 76% but signal only got up to 10% then it disconnected and lost the link
again. Any ideas.

Hi

May be you have electrical noise, http://www.ezlan.net/wbars.html

Try to change channels.

Otherwise you might be out of functional range.

May be this can Help.

Saturn:

Seems the one way to tell for sure is to move the PC with the connections
problem next to the router, just to make sure your setup is right, and avoid
spending money if the problem is the setup.

In fact, when I first networked, I bought the PC into the room where the
router was, I wired the PC to be networked directly to the router first, then
disconnected the wire, and tried it wireless, just to be able to eliminate
issues of setup, distance, noise etc.

I had to move the USB adaptor around on one PC a bit to get the optimal
reception. Because I couldn't do this with another desktop that I installed a
PCI card, I bought an antennae for $8.95 off of ebay, and placed that
antennan about 18" off the floor, rather than use the original antennae that
was on floor level.

Other options I looked into was:

- Moving the router to the center of the house. This would put the router 10
feet closer to the wirelss units, but that means I have to stretch cable to
the other side of the room, and run an ethernet cable back to the wired PC. 
Where it sits right now, at the side of the house, half of the signal is
broadcasted to the house next store.
- Replace the antennae that came with the router with a larger one (spend
around $59.95 or more).
- Keep the router where it is, and intall a repeater (spend another 99.95 or
more).

One problem I noticed was my refigerator stands between the router and my
wireless units, and  moving the router would also solve that problem.
Fortuantely, movng the adapter on one unit, and adding a small antennae to
the PCI card of another unit solved the problem for me.

HI

thanks for all your replies. Tonight i have signed on and eventually managed
to get on the internet on the othe pc but not for very long, it then
disconnected. The noise level throughout has been very low even when
disconnected, dont know if that means anything.

Can i just say that i am very technically illiterate, i managed to do all of
this so far due to following instructions in the packet so to speak. I reckon
i have done everything right so far in that it has been able to connect.

I am however completely lost with some of the advice ie change chanels,
extending 10 metres,, (how) etc. I looked at the links supplied but the info
is way too technical for me.

Just to confirm the wired connection is upstairs,, at front of house,
directly below is the living room which then goes through to the kitchen,
then to the dining room which is an extension which would have been outside
back garden at one time and that is where the other pc is. The house is brick
built,, read something somewhere that that made a difference. Could you
please when replying, although i appear to know what i am doing,, think of me
as a complete IT illiterate,, i feel like one just now. lol
