Second i got today router Flint 2 i connect all and i set Qos and limits and all was ok (low bufferbloat and jutter) , but update pop out so i press ok and now jitter jump to unloaded +50ms , download +25 and upload +42ms.
So my question is its possible update broke somethink and if yes can someone told me what firmawre is instaled default
Yes i know all settings gone , so i follow bufferbloat quide and set all again inqos . What i dont understand when I make test on pc all jitters are over+25ms but when i make on smartphone (wifi 5g to router) all jitters are better( alot better , almost perfect) and speed Down and up almost the same like on pc
