Ok - this could take a while….
Can you post if this is correct:
You have a wireless access point with an IP address of xxx.xxx.xxx.xxx and a subnet of xxx.xxx.xxx.xxx
You have a deskop machine with a wireless card in with a IP address if xxx.xxx.xxx.xxx and subnet of xxx.xxx.xxx.xxx
You have aTR3 which has a wireless address or a fixed network connection?
On each machine run a cmd prompt (Win+R), type IPCONFIG /all and paste into a new message then I have some more to go on…..
We can sort this out - it was working so it’s just a case of figureing it out
