Just updated my 2 year old Time Capsule to the new “Simultaneous Dual-Band” edition – with breathtaking performance increase!
I have always had the problem that my TimeCapsule’s 802.11n network was quite slow due to conflicting wireless networks.
I have now taken the plunge and updated to the new, 2Gig model, supporting "Simultaneous Dual-Band".
"Simultaneous dual-band 802.11n Wi-Fi base station. – Time Capsule is also a full-featured 802.11n Wi-Fi base station. It operates in the 2.4GHz and 5GHz bands simultaneously and now delivers even faster performance and greater range for your Wi-Fi devices."
This just solved all of my issues – the performance increase was enormous.
