Thanks for the input FurryNutz, I like tweeking, but in the end I'm running in N-only mode and its been very stable since I gave my access point WIFI router a different SSID from main one, even though they are on a different channels I would get conflicts which could only be resolved most time by changing mobile device SSID or channel but it was a pain and not consistant.
With respect to accessing video (I have 6 cameras which I ran at full bandwidth (20 fps, 640x480, high quality) I like stressing things to see stability.
1) DCAM View from PC (LAN connected)
2) Justconnect+ form Iphone or IPAD (ususally on 5 ghz band)
3) Justconnect+ from android table (ASUS MeMO) on 2.5ghz band
4) IP CAM view (all mobiles)
5) DCAM View from mobile devices ( I hate how slow it is to see the video)
6) mydlink Lite from mobile ( also slow to see video)
some comments:
DCAM View on PC is so solid and 2&3 are almost a tie and might be equal if my Droid was higher end.
One thing about IP Cam view thats nice is the overlay color turns red when the connection is not working, this is very important knowing if the feed is live or not. But I don't like the green like not blinking when viewing all videos together.
I don't like the fact that the cameras don't stay on the wifi channel that you set them to in infrastructure mode.
