I have an AC3100 set up as a media bridge, and whenever I try to do transfers of large files from my NAS drive, it drops off too. It seems to happen only when I am doing Samba transfers at high speeds. All devices that are connected via the media bridge drop off, and the lights on the unit turn off as well except for the power light. I have been having this issue for a while, but never bothered to address it. I am running Merlin 384.14_2.
