I've patched to 10.7.1. Still have this problem. Web searches not turning up anything specific. Here's the run-down: --Macbook air 2011, top end 13" --On home network with several macs and an AFP enabled NAS --All macs can see each other and the NAS via shared section in finder --The air when WIRED connection can see all macs and the NAS via shared section in finder --Connect Air via WiFi and cannot see any network shares in the "shared" area in finder --Other computers CAN see via wifi --If I hard-code the path via afp://x.x.x.x I can connect via wifi --This sounds great but TimeMachine keeps breaking and won't backup due to this issue (to my NAS, which 3 other macs backup to) --Internet works fine regardless of connection This seems to be an issue with Wifi. I've tried: --PRAM resets --Deleting caches --Deleting keychains --deleting wifi profiles --reboots Same issue regardless. Anyone have any ideas??? This is bugging me. Badly.
