Slow download rate

Hi, I’m facing slow download rates and just have seen a few other threads here but without a solution. Operating on Raspberry PI 4 with 2 GB RAM. Green is connected with built-in LAN to internal network and red0 is connected to the modems switch. via USB ethernet adapter. Directly connecting the laptop to the modem results in speedtest with 266.80 Mbps download rate. Executing speedtest on ipfire results in 107 Mbps. Somehow the green and red adapter seem to be restricted to about 100-130 Mb…
