GreenBay42 / FurryNutz:
Very nice find!  I can indeed confirm that the European 1.21 Firmware now fixed the 5GHz - secondary channel issue on the DIR-895L router.  The speed and signal is very good.  On a side note I tested DD-WRT on DIR895L... it is lacking CTF (so on a wired connection speeds are pegged at about 300Mb).  Also, WW-DRT firmware had the speed and signal issue on 5GHZ - secondary channel, no signal and slow slow speed.   Thus, I reverted back to stock.  And with this newly found European version is very good (speed & signal on 5GHz)... I'm not going back to DD-WRT.  Thanks again guys.  Good job.
