Losing Faith in SL and Apple Tech Support
Senior Pilot, here are a few more things you will discover with wireless on your new MBP (or Air) and SL.
1. You will go to different wireless hotspots - sometimes it will work and sometimes it won't - meanwhile you will suffer the indignity of your Windows buddies having theirs work all the time.
2. You will delete and create new dummy locations. The new Automatic will sometimes NOT work at all - even if u restart your new MBP twice, start new dummy locations, force a renew of DHCP lease on TCP/IP and so on.
3. The MOST reliable way is to carry an ethernet cable with you ie you remain tethered to the wall whilst in a different hotspot.
4. You can demo the fault to an Apple expert at a "genius" bar (I did in Sydney and in Singapore) and they will tell you it is a "known fault".
5. If you Google "Snow Leopard and WiFi problem" the most subscribed to thread on the Apple Support forum is the SL/WiFi problem thread - and guess what? Not a squeak from Apple on this.
Unfortunately, and out of desperation, I have reverted to my old G4 laptop running Tiger with absolutely zero problems on WiFi when I absolutely need wireless to file flight plans or get the weather.
I hope Steve Jobs gets better and forces Apple to fix these problems!
