Ive bought a USB to ethernet adapter and an ethernet cable, and ive plugged the ethernet cable from the wifi modem to the usb to ethernet adapter into my laptop, and it hasnt affected the speed of my internet on my laptop. I took an internet speed test before and after i plugged in the ethernet cable and adapter, but it hasnt changed at all. Some information is that theres an orange flashing light and a green light thats always on on my USB to Ethernet adapter. -Joseph
