Received my Thinkpad from Lenovo repairs earlier this week (vga output issue). A couple of minutes later the Windows 7 installer was running.
After all this time I assumed MS would have fixed my biggest gripe with Vista. Network copy performance. Rest assured... it's even slower in Windows 7.
update: Copying large (200 MB) files fails with the error "Make sure you are connected to the network and try again". It looks my Windows 7 adventure will be a short one.
update2: Updated the wireless network driver (this version) as suggested in the comments. Still not working, not even with Robocopy.
update3: Turned of autotuning with "netsh int tcp set global autotuninglevel=disabled", don't forget to reboot. Fixed! Copying files over the networks is still sloooooooow.
