Re: Cannot Access Computers on Home Network

All 3 computers are running McAfee Security Center provided by Comcast. I
changed settings under Managed Networks that have made it possible to
successfully ping using the IP addresses. However, I cannot ping using the
computer name.

When I go to Network Places I see each computer. If I try to access other
than the local machine I get an error message that "\\Computer Name is not
accessible. You might not have permission to use the network resource. The
network path was not found". I'm not sure if the problem is due to Windows
or a McAfee setting.

Thanks for the help so far. If you have further ideas I would appreciate
the help.

I have 3 computers all running XP Home SP3. I recently changed from a router
that supported ethernet and phone wire connectivity to a wireless router.
All three could share folders and printers previously via Windows home
network. Since changing to the wireless router (netgear wnr2000) none of the
computers can connect. The IP addresses are all in the range 192.168.x.y
where x is the same for all three and y is in the range of 1 - 10. All have
the same subnet mask and default gateway id's. Attempts to ping one another
all fail, pinging each local machine is successful. The cable modem is
connected to the router via ethernet. All three computers can access the
internet through the router.

I've tried everything I know to fix this problem including running the
network setup wizard using different workgroup names. I also tried using the
wireless network SSID as the workgroup name. No luck! Any help would be
appreciated.

What is the anti-virus software or Internet security software? I
encountered this last year (2008) which I switched my own router.
Turned out my Norton 360 must be told to trust the new LAN IP subnet
(192.168.0.xxx) and the wireless SSID.

Also, several anti-virus software can offer an Internet worm virus
blocking feature. This usually blocks the ping by name (ping \\PC1)
but should let the ping by ip address through (ping \\192.168.0.1.)
