Hi everybody, I have a technical question concerning the Airport Extreme (4th generation) and wireless n/g-switching: I installed the AE yesterday at my parents house with n-standard (2.4 GHz) backwards compatible to g/b/a. My parents solely use a "n"-capable iPad which gives them best Internet speed and range in the whole house. However, when my sister visits them she will use the Internet with her "g"-only notebook, too. (Or is it even still "b"???) I guess this will downgrade the wireless standard of the WLAN in my parents house to "g" (or - heaven forbid - even "b") all together. My question is: When she leaves again and her device isn't connected anymore – will the Airport Express (now that there is only the "n"-device again) automatically go back to full n-standard again? Or would you have to turn on and off the router and/or the iPad completely in this case? I'd really like to have the best possible connection for my parents as they have broadband Internet and a house where the Internet experience is significantly better with 802.11n. No problem if the WLAN is "thwarted" for the few days my sister is there, but it should go back to full performance when her bottleneck notebook is away again ... Maybe this is of no concern anymore because of the "Dual Band" functionality, but I always understood this feature as having 2,4GHz and 5GHz simultaneously, not "n" and "g". And even if second, I guess it still hurt the performances of the "n" network ...? Would be nice if somebody with the needed tech knowledge could give me a short answer if I have to worry about the Internet experience for my parents or not. (I know they wouldn't say anything even if the surfing experience suddenly gets much worse.) Thanks so much in advance!
