Wireless and wired won't connect to each other

Got the bu**er!!!!!!!!!!!!!

Thanks for all the suggestions - certainly helped the thought processes.

2Loose was very close

I don't use the XP firewall, but the one in the Kaspersky package. The 'network attack blocker' in Kaspersky had set the status of the workgroup network to blocked despite my having set it to trusted status in the firewall settings. For some reason - don't know why or how - it didn't block traffic within the wired or wireless parts of the LAN, only when it crossed that boundary. The printer is addressed only by its IP address so it was still accessible.

As a result the Kaspesky firewall was blocking the traffic.

There must have been something which upset the Kaspersky system or the problem could have come when the Kaspersky software upgraded itself when I renewed the subscription, as it had done the change on all 3 computers. Setting the workgroup back to a trusted network and removing it from the blocked list has restored normality, whether it stays that way remains to be seen.

Well done for persevering and finally cracking it.

Try running a test with the firewall switched off.

Turning the firewalls off wasn't enough - had to turn that network attack bit off as well before it behaved! What I should have done but didn't when following your suggestion was turn the Kaspersky software off completely and try it, which would have localised the problem much earlier.

Right PITA. Thanks again for all the help
