Hi all,

i have bought an Archer VR2800 in a correct way and i haven't problem to navigate on web with all devices that are connected to it. Problem there's when i download or upload something from http or ftp protocol, internet connection after some seconds goes down, i can see it from backend router --> state connection and in these moments there's not ping to google.com or other site, i haven't configured QoS but even configuring it nothing solve.

Actually i'm using as firmware: 0.2.0 0.9.1 v006c.0 Build 170110 Rel.33619n
and hardware: Archer VR2800 v1 00000000

i need to solve it because in this way this router isn't usable, i can add at my problem that changing Archer VR2800 with defaut ADSL provider router i haven't problem.

i hope in some suggestions / solutions.

Thank you.
Regards
