Hi, I have had a really smooth install of iATKOS v51 onto my Dell E520 apart from 2 easily fixed issues:
1: No Sound but thanks to VoodooHDA.kext........Thankyou !!
2: Intel 82562v 10/100 not working - but easily and completely fixed using Intel 82566mm.kext

Now this is where I am stuck, my router is on the ground floor of the house and can't be moved as that is where the telephone point is. I normally access the internet on this machine via a Netgear WG111T Wireless USB 2.0 Adapter for which there are no kexts that I (and it seems plenty of other people ) can find. So to get Internet access I am plugging that adapter into an XP laptop and trying to use an Ethernet cable from this into the tower running Leopard. And try as I might I get no further than seeing the connection being recognised.
Could somebody spare me a little time and let me know what I need to do do get this working ?
Thanks in advance from me and everybody near me.....

It would probably help if you told us what you've tried so far.

I assume you've enabled Internet Connection Sharing on the XP machine?

Can you ping the XP machine? by address or name

Thanks for the reply, at the moment I have got the dreaded WG111T plugged into the XP slaptop and have a working Internet connection on it. ICS is also enabled. After that,as you have already sussed I'm in the dark as to what steps I should take next, having never dealt with anything like this before....Any help you can offer will be greatfully and greedily accepted so please let me know what more info I can provide.
Thanks again

Well, try pinging the XP machine. Start by opening a command prompt in XP, from the Start menu select run, then in the window that opens type

cmd

and hit enter, that should open a terminal for you, now type

ipconfig

to get the hostname and ip address for the XP machine. In OS X either use a terminal or Network Utility to ping those. From a terminal you can do

replace www.google.com with the ip address first and then the hostname.

Post back the results.
