internet speed test is faster when battery charger is not plugged in

[ralph0312]

When I run the speedtest without the battery charger plugged in everything's fine, whenever I plug it in the results just massively drop.

Speedtests results

-without battery charger: PING:4, DOWNLOAD:121.34 Mbps, UPLOAD:20.38

-with battery charger: PING:4, DOWNLOAD:34.51 Mbps, UPLOAD:20.50

If anyone can help I'd be so grateful!
