I've put my Starlink (gen 3 with gen 3 router) in bridge mode and connected it to the WAN of a TP-Link router (EX-141/EX-220/Ax1800). I can connect to the internet, but download is really slow (0.7mbps) while upload is high (30mbps).

AI told me this is a duplex problem, when the WAN port speed is misidentified. Indeed, it shows up as 100mbps only:

LAN1 - Disconnected

LAN2 - 1000mbps

LAN3 - Disconnected

WAN - 100mbps

I already tried: another brand new router, another brand new cable, and connecting to the second starlink LAN port. All give the same behavior: either fast download, or fast upload, but not both.

Is this a common problem? What can I do?

TP-Link is in router mode, but I also tried AP mode, etc. I have an IPv4 and also tried with IPV6. I resetted the router multiple times, did a brand new configuration, etc.
