Cable Forum - View Single Post - Dropped Connection (due to 2nd PC on n/w)

Greetings all from a Newbie.
I wonder if anyone can help with my constant dropped connection please?

PC1 - Connected to NTL 200 BB modem via ethernet cable - stable solid 4MB connection, shows 3.9Mb downloads via speedtest.net
Runs Windows XP Pro, ZoneAlarm, Proxy+ and has a wireless LAN card.

PC1 connects to PC2 over an ad-hoc wireless network - very solid connection which starts up automatically on PC2 bootup.

PC2 - connects to internet over wireless network, via proxy+ on PC1 - all proxy settings set as required in Proxy+

PC1 is happy as anything and I can surf for days on end with no connection problems. PC2 will connect immediately (via wireless and proxy+) to the Internet and is able to access web, msn, etc no problems, for a random amount of time, until suddenly I get a 'cant connect error' and connection dies for both PCs. Checking ipconfig on PC1 shows loss of gateway. Wireless network is still connected and works fine.

Anyone have a clue why? Both BroadBand and PC helplines at NTL were of no use - neither could grasp the concept of proxy server software and told me to buy a router or use ICS - which frankly is just a built-in proxy server anyway! Is this a DNS problem? If so why would it kill the gateway?

So many questions and possibilities ... Glad of any pointers that you may have.
