tosh windows xp won't see others boxes wirelessly

Hi guys just a quickie, i have a tosh laptop that will "see" the router and window 7 boxes on the lan quite happily and share resources. When you un plug the hardwire and use wirelessly the internet and logmein work just fine but there the networking ends. The router is described as an unknown internet device and no other machines are shown. The workgroup is the same and pass through is set on the netgear router. This problem has started since the old "server" an xp box was changed to a new W7 one. Thoughts please.

If you can, now, hook up the XP machine wired and see the Windows 7 machine (yes?) and then two minutes later, unplug the Ethernet, connect by wireless and cannot see the Windows 7 machine, then the likelihood is firewall in the wireless router. I assume wireless keeps the same subnet and same IP addressing. The wireless security may have added some firewall restrictions.

More infomation... No firewalls on dgn2200 router active, norton anti-everything turned off.. but here's the kicker.. laptop ipconfig says ip address ends .11 all good , except looking at attached devices on router , no number 11 listed at all !.
No reply to ping to one of the attached machines but obviously can ping the router since i'm connected to the laptop via logmein.
How weird is this, if i can't ping across from the wireless side to hardwired side then file sharing has no chance.
Ideas on "missing" no eleven even though i'm using it.

Are you connected to the correct router?  That is, is your machine connected to a different (nearby router).

Delete the wireless profile on your laptop, restart it and remake the profile. Make sure it is connected to your router.

Consider backing up the setup of your router and doing a hardware reset of the router. This means setting it up again.
