Hi,

when I connected my computer via the cable modem directly, speedtest shows the correct download/upload speed my provider supports. It is 500Mbps down and 50 Mbps up.

When I am connecting via TL-ER5120 and the cable modem in bridge mode, it is "only" 200 Mbps down and still 50 Mbps up. At the moment I do not have a second connection, so only one WAN port is active and no routing/balancing is configured.

I don't see any settings which could limit the download.

What can I double check to have the full 500Mbps down?

best regards,
Bernhard
