WUMC710 - Fails to stream properly and overall poor performance.

Question

I am an IT professional, dealing with wired and wireless devices from cisco and non cisco, for several years now.
I now have a EA3500, which is the 3rd linksys router i own (after wrt54gl, then wrt160nl)
I bought a 5 Ghz wireless bridge WUMC710 two weeks ago. The main purpose is to stream video.
I have tested the location where the bridge is located (5m from the router, no walls) with my laptop, being able to copy an 4GB file at a steady 9 MB/s (real data documented with print screens)
After connecting the laptop to the bridge, and disabling internal wifi, the same file, downloaded at 6MB/s speeds (also documented).
The matter got worst when I tried to stream video. Every stream that I tried, the video stoped every 5 minutes, wireless active, devices active, but no streaming. After a while (15-30 seconds), streaming resumed where it stopped. After another 5 minutes, another halt, and so on.
If the video in HD, the halt period shortned to 2 minutes.
Supose bad memory management. Tried Chat and Phone support, but no solution found.
Can someone help?
Thanks in advance.

Hi
@phillippeannet, @imncloudnine: tkx for reply.
Update:2013/07/10
HW/SW infrastructure considerations:
On the Router EA3500:
Switched over to Classic FW, stability issues
To enable 5GHz, 40 MHz bandwidth, QoS must be enabled, with the WMM option. Don't ask me why
Also, support chat was very nice, but also, very limited. Only effective achieved milestone was a complete router reset and reconfiguration from my part .
On the Bridge WUMC710:
Firmware update to latest patch (1.0.01b18).
QoS enabling with WMM option.
Brigde running on 60% signal strength, theorical speed of 405 Mbps
Previous FW problems:
Poor streaming performance from Blueray to Youtube (yes, youtube). Almost anything streamed over this medium had 2-5 minutes of streaming, followed by 30seg-1min lag, and then restarted the hole process. Very frustrating.
Also, SW freeze when device connected for long periods (1 week), which forced me to reboot previous to usage. Very very frustrating...
Latest FW, yesterday testings:
Only tested blueray, but seems promissing, much much less lag, but still present.
Future tests:
Blueray with no network clients other than media player, on 5GHz network
Check for SW freezes
Final considerations.
Wired switches and routers work much better and are much cheaper. Also, they do exaclty what is said on the box, out of the box, not a couple of months, and a bunch of work hours later.
Thank you Linksys for reminding me that.
