Hi my name is ***** ***** I can assist you. 802.11n is a wireless standard that pertains to speed of your wireless connection. MIMO (multiple-input multiple-output) is another word for it where using more that one antenna will give you higher speeds. This works best for streaming applications like NetFlix to allow you to have the fastest connection for your streaming device to your cable modem or wireless router. The TC862 does have 802.11n enabled by default so you should be getting excellent speeds from your wireless device to the router.
Let me know if you need any more help, I'll leave the ticket open for your response. If I was able to answer your question, please rate my service with the stars above with 3 stars or higher if I was able to provide you with excellent service. Otherwise, I will continue to work on your issue until you are satisfied.
I wanted to check in again and to see if you still needed assistance.
