Beware Doing This With Your QoS Bandwidth Limiter

[LoneWolf3574]

Last night I did a reset on my RT-AC3200 that was running the latest Asus firmware (378.9529) then installed the latest Asuswrt-Merlin firmware (380.58) after the reset was complete as it was acting a little hinky (Bandwidth Limiter wasn't working at all). Everything worked great until I got to the QoS, enabled the Bandwidth Limiter and set the target devices & speeds. After I had entered all the information and applied it, I found that I could no longer connect to my home network, the router or the internet. I spent the next hour thinking it was my computer only eventually to find that my laptop, cellphone, tablet and my wife's laptop were effected as well.

I finally disconnected everything, including the modem, left the computer I was working from connected to the router and, viola, I could connect to the router again. After plugging each network device back in (printer and NAS) I logged out of the router and checked to see if I could reconnect to the router. When I finally plugged the modem back in, I couldn't connect to anything again, so I disconnected it and discovered that my connection to the router and home network worked again.

What I had done to cause this chaos was create a list of bandwidth limited devices by the name I had given them on the router with no associated MAC. It appears to be a bug that blocks all access to and from the router so long as the modem is connected to the router. Lesson learned, do not make a Bandwidth Limiter Client List with just names, use the MAC address or wait until the device is connected to limit it.

I don't know if this bug affects the official Asus firmware, but I can definitely say that it does have an effect on the current Asuswrt-Merlin firmware.

Thanks for sharing...

FWIW - spent an evening helping out a friend that was in a similar situation - come to find out his Broadband provider actually had an outage right about the same time he was tinkering with his router
