All right I lept! (First leap into networking?)
So I created restore points on all three puters and then ran the wireless network set up wizard, entered the WEP code from the router in the wizard in the process. I called the network after my house name and ran the set up on the other two. (Used memory sticks)
Ran IP config/all and pinged the other computers and got a reply from the other two.
Ran round all three setting up file sharing on C drives and Documents folders, so far so good!
Went to network places to find the other folders...Zilch!
Viewed the other networks to find that I had three! Two I had tried to set up previously (With no success) and then found that two computers were on different named networks. Sorted that out in named computer and low and behold two of the three were visible.
Configured the third on the same network and all is well. All three are seeing each other and running well. Printer is up and running and I have achieved all I wanted..............except!
It's just that I ran the network wizard calling my network 'Woodside'? and the computer has found the computers on 'MSHOME'!....Just why is that, and did the WEP ever get configured.
When I started I found the three networks that I had run, now I only see the MSHOME one. (There are no computers now on the others so I guess I'm not seeing them)
I have also changed my BT broadband setting in the router from PPoE to PPoA at Belkins suggestion, and now find that I am having to repair my wifi connection on all three computers every time I log on. I don't know the difference between the two. Frankly I'm not sure Belkin are right on this, has anyone any advice?
Finally, my thanks to all of you that replied. It was exciting and satisfying to finally see my computers networking together especially as it has been the final leap for me. It was, and is, still an area where there be dragons!, but at least I'm up and running.
Thanks again.
