Hi, Not sure if this has been discussed before and if so please provide me a link because I've been looking for an answer for this one for a bit. I have two laptops, one 32 bit Window 7 Premium and another laptop 64 bit Windows 7 Premium. They are connected wireless through a Buffalo WHR-G300N router. What happens is this. If the 64 bit machine is on and the 32 bit boots up the sharing is available and all is well. If the 64 bit machine goes into hibernation (lid down) and then back to operation the sharing is gone. I can't see the 64 bit machine at all and vice versa. I have setup a Homegroup setup and the 64 bit machine is the one with the password etc. Homegroup requires IPV6 from what the troubleshooter tells me. Another point I will make is that one machine is from Australia and the other is from Finland. Aussie machine as English with Aussie region settings, Finnish machine as English but with Finnish regional settings. The 64 bit machine is an HP and the 32 bit machine is a Compaq. Both are relatively new machines, less than a year old. I've done a lot of networking and have a certificate in networking but this one has me stumped. Any suggestions would be welcome! Thanks.
