Tplink AX55 V1 firmware 1.5.11 massive bufferbloat
Tplink AX55 V1 firmware 1.5.11 massive bufferbloat
Just wanted to report an issue after updating my Archer AX55 V1 to firmware 1.5.11.
Right after the update, everything seemed fine. But once I enabled QoS, the router basically became unusable.
What I’m seeing:
-
Massive bufferbloat as soon as QoS is on
-
CPU usage spikes straight to 100%
-
RAM usage looks normal
-
Ping jumps from a stable ~49 ms to 290 ms+
-
Web UI becomes extremely slow and at times I can’t even log in to the router
Disabling QoS immediately brings things back to normal, so the issue seems directly tied to QoS behavior on 1.5.11.
This wasn’t happening on the previous firmware with the same settings and same network load.
Has anyone else on AX55 V1 experienced this on 1.5.11?
Any known fixes, or is this a confirmed firmware bug?

Experienced 2 issue just as of now.
1. The router became laggy. unable to login to router even with local login, needed to restart the router in order to login.
2. Had an issue where my 2x RE315 wifi extenders under onemesh is connected but not having internet connection. Restarting the router fixed this.
