I have two ac68u routers and have been using them in aimesh ever since merlin added this to his releases. I've been updating both the router and node sporadically with the latest merlin firmware over the last year. They were working fine until about a few months ago. Any device connected (wired or wireless) to the aimesh node would experienced random huge latency spikes or dropped connections. Took a while to find out it was the aimesh node causing the issues. Initially, I didn't think it...
RT-AC68U aimesh node dropped connections/ latency spikes with firmware 384.81049 and later
