Hi all

I have a netcomm NB9W router/modem with wireless network setup.  have 2 pc's connected to this router over wireless.  i am able to ping from PC1 and PC2 to the router but am unable to ping PC1 <-> PC2.  All WAN services are running from both machines.

the router can ping both machines.  When I hardwire a PC into the router over cat5, i am then able to ping PC1 <-> PC2.  Any ideas on how i can trace the problem?

Rgds and thanx for your time

Andy

are they members of the same workgroup & do they both have enabled netbios over tcp/ip?  do a start - run - cmd - ipconfig /all & post results here for comparison.

hi all

i have not got to the workgroup stage yet, i simply need to ping.  i decided to reset the Netcomm router back to defaults and supise surprise, it now works.  i guess the tcp/ip stack on the netcomm box was corrupted so yeah, all resolved.  

Thanx for all your help guys and keep up the good work
