On older firmware 384.45xx entire network has access to full Gig speeds, usually test from fast.com at 800-900Mbps.
Ever since that firmware speeds drop down to 200-300Mbps for all devices on network. Wired and wireless.
Narrowed it down to be QoS bandwidth Limiter being enabled for some devices was the cause. On the newer firmwares if i disable that feature and manually reboot router full speeds return. If i re enable it speeds drop for the entire network, not just the devices set to have limited bandwidth.
Im currently talking to Asus try get resolved, have been for last 2months now.
Currently on their beta firmware version 3.0.0.4.386_39058 and issue remains.
They have most recently tried saying Nat Acceleration was the cause but its not confirmed by disabling it and rebooting router but speeds still slow..
see most recent responce below...
Please see the response from our R&D Team below.
After detailed review of this issue, we have found that the root cause is the conflict of whether process packet recognition.
To achieve the function of the Bandwidth Limiter, which in needs of recognition of each packet to throttle bandwidth. While NAT accelerator is a mechanism to speed up packet transition via by-passing the recognition process. Therefore, the two functions are conflicted in the process of packet recognition, users may only choose one function at a time.
They have also tried saying this is just how bandwidth limiter works, also not true bandwodth limiter should only effect decices set to have limited bandwidth and the rest of the network shoudl remain as normal unrestricted.
If i downgrade to older firmware anything from this version or earlier 384.45xx everything is fine with bandwidth limiter enabled and all but if update to anything newer than that and network wide slow speeds 60% loss..
Has anyone else had this issue or if you have the speeds close to mine can you replicate it?

Same situation here.
Network Topology
FTTH Connection to ONT in "Data Closet"
1 Gbps download and upload speed
RT-AC86U connects to ONT with CAT6 as AiMesh router
Another RT-AC86U and RT-AC68U as 2 AiMesh nodes
After the upgrade to 3.0.0.4.386.40451, my wired speed was throttled at 400 Mbps DL and UL. After removing bandwidth limiter, it is back to 1 Gbps DL and UL.
However, wireless speed is horrible, only at ~40 Mbps or even less, within a few feet away from the main router. Any idea?
