Windows 7 Network Issues

[Dazza]

Posted similar before but got no answers so here is another attempt but
slightly different

1 laptop Wifi - Windows 7 Ultimate
1 desktop PC hard wired - Win XP Pro
WiFi router Linksys WRT54GS flashed with DD-WRT firmware
Both set to the same workgroup name
Both can access the internet

All was working fine until all of a sudden.....
Laptop can ping PC but PC cannot ping laptop either by name or IP address.

Switched off firewalls but problem remained
Switched off ipv6 on laptop but again no joy

I have searched the web and followed many advises found but I just cannot
get the PC to see the laptop.

Any ideas that will help save my sanity folks?

Regards
Daz

Open up an administrator mode command prompt by right-clicking and
choosing Run as Administrator, or type cmd into the start menu search
box and then use Ctrl+Shift+Enter. Then enter the following command:

netsh firewall set icmpsetting 8 enable

Laptop should respond to ICMP pings from now.
