Does anyone have clue about what networking issues are adressed in this update?
My story:
I switched to Mac about a month ago and since then I have had a lot of problems connecting wirelessly to D-link routers. First I got terrible speed and unreliable connection towards my existing DIR-655 Wireless N router. I got it working reasonably after changing place on the router (now it is less than 2 meters from where I usually sit) and trying different settings after reading numerous forum posts on the subject (there are a lot of people having similar problems!). I wasn't satisfied with the speed, though.
To increase the speed I bought a D-Link DAP-1522 access point to separate my 802.11g clients and my 802.11n clients to the 2,4 GHx and 5 GHz bands respectively (having g clients on the same net as n slows the entire network down). This is how the Airport Extreme does it (but I don't want that one as it doesn't provide a web GUI making it impossible to administrate remote).
It took me a lot of fiddling before the MBP even connected at n speed to the new access point (g seems to be less of a problem). For example, when in n-only mode it doesn't even discover the network (this is true also for the DIR-655). When in a/n mode (WPA/WPA2 AES/TKIP) it discovers it and I can connect at 300 Gb/s. However, it seems that the network card forgets the network after a while and I am again unable to discover or connect (e g after a night in sleep mode).
I also can add that I have two PCs on the same network and they do not have the same problems.
So, Apple; it's time to prove that you can deliver both premium hardware and software. I have high hopes for this update!
