any necessity for firewall and anti-virus on client computer?

I have a very effective firewall and anti-virus program on my host
computer with router. I have two client computers. One has no firewall
or anti-virus, and never has any problems. The other has both firewall
and anti-virus, and is continually disconnecting from the internet.
When I remove the firewall and anti-virus, it performs much better. Is
there any reason for keeping the firewall and anti-virus on a client?

Yes. Especially important as they stop different things.

If you have an always on connection to the internet, a firewall is
essential. It protects your PC from constant probes on the internet. A
router with NAT will serve well as a firewall for inbound. but it is
important to have a firewall to protect from outbound viruses and trojans.

Also, many companies run anti-virus on both file servers and individual PCs.
Enough said.

Some anti-virus and firewall software doesn't work very well and may cause
problems. Good reason to try another product.

I use and like AVG antivirus www.grisoft.com and Zone Alarm
www.zonelabs.com Both are free for personal use.

What O/S is being used on the client machine that you're having trouble?
What is on the other machines for the O/S?

I have Windows XP on the host machine. The client machine that is
unstable has Windows XP and a Dell adapter, the other client machine
(notebook) has Windows Millenium and a NetGear adapter. If the Netgear
adapter was a USB type, I would put it on the other computer to see if
that made a difference.

I don't think the FW or the AV has anything to do with the problems on
the XP Pro machine. It may be due to the WZCS Wireless Zero Configuration
Services that can seek out other networks in the area and drop the
connection as it does it.

1) Disable WZCS on the O/S
2) Don't use the card's utility to config or show signal strength
3) Download the driver for the card from its Website
4) Use Device Manager to install the driver and configure the card
5) NIC Properties enable show Network Icon so when you mouse over the
icon that will show in the Job Tray it will show signal strength.

Those are the procedure I used to make XP and wireless rock solid on my
machine. You can give it a try if you like.
