Wow... I thought this issues were all in the past.  We put about 15 of them in 
service in the past 2 months and hadn't had a problem before today except one 
went bad within a couple days of install.  Nothing intermittent or weak like 
this.

That's too bad.   Looked like a good router most people could afford.   Cost is 
about $ 55 higher on the 2011 with Wireless.  Some customers might cheap out at 
the price hit.

Paul,
There are posts on the MT forums of complaints with similar issues. I have had 
similar issues with the 751 and 951 units. Signal strength is sporatic and 
throughput is initially ok, then quickly drops off to zero.  I switched to 2011 
series and have never looked back. MT keeps avoiding questions about this on 
the support forums so it's highly unlikely that they will ever admit the root 
cause.  My customers were unhappy with some of the units I deployed, so I just 
quit using them alltogether.
