DMA2100 and 802.11N

[La Laja]

Just a couple of days ago I setup a DMA2100 with a Linksys WRT350N in wireless mode.
The WRT350N wireless setting were are left as default factory, which according to the usermanual are the optimal for a 802.11N (draft) net.
However, setting up the DMA2100 in wireless mode, it indeed finds the wireless net but it reports it being a 802.11G net !?
The DMA2100 works more or less with this net but after some time I get a warning popup in the upper right corner of the screen with 'network issue' and at the same time a breakup of the video stream.

Very strange !! I was investigating this issue and playing with the little antennas on the back of the DMA using the 'tune network' facility in the Tasks section of MCE. While running the performance monitor (graph view) I fumbled with these antennas and found that the best performance was achieved if I removed the antennas completely!! In fact the difference is very small but still a little better without the antennas!!
At the start of the 'tune network' it tests the overal performance . In my case it reported 'Your network may not have enough bandwith for consistent performanceon your extender device'.
I wonder if anyone else would be willing to do the same test and tell me if they got the same result?

I found the problem! Apparently the wireless N standard doesn't allow simple WPA security. It needs WPA2 with AES encryption (or security disabled). In wireless N the antennas do matter! Anyhow, all problems solved.

I have a 5Ghz Netgear WNHDE111 802.11n Wireless Access Point on the way

I was wondering how far away is your router from the extender and how many walls etc are in the way?

What sort of speed does it say in the network test if you view the graph???

Thanks

There is just a wooden panel as obstruction and not more than 5 meters distance. In the 'tune network' utility the speed hits the maximum (ceiling). Only when I walk trough the direct line between the router and the DMA does it show some degradation.
(Despite this I get the 'network issue' warning after about 1 to 2 hours of video streaming with the DMA. )
Good luck
