Guys, I may have good news. I just found that there was an update for "Access point" in the Windows app store. In the description it said something about "robustness improvements". I Installed it and am now connected to Lumia 925 Internet Sharing with my Mac for literally 20 minutes with no interruption!!!
I'm not sure if this update is related to WP8 Update 3 Developer Preview I installed yesterday. It might be that WP8 Update 3 has to be installed before this update becomes available. The good thing is - WP8 Update 3 Developer Preview can be installed for free (you just need a live account and an "app studio" account).
Lol it's already 25 minutes now. I'm so happy Will test it the whole day tomorrow.
That would be great news - but installing the developer preview isn't an option because Nokia has confirmed to me on Twitter that doing so indeed voids the warranty.
