I have been working with QOS and Bandwidth Limiter on my N66R running 380.59. Have changed settings a couple times a day to learn what the QOS/Bandwidth Limiter can do. Also involved turning on and off the CTF. Yesterday I noticed the N66R was reporting only 123MB of RAM and most of that was used. A Factory Reset from the Administrator console did not change the RAM. What worked was a Factory Reset using the WPS button from a power off state. Now the RAM reports 234MB! I did not save the log before I did a reset. Just wanted to report this in case it happens again to someone.
