I have a fibre internet connection which runs through a Fritzbox with ethenet ports and wireless connections. I have a 100/50 MB connection with Snap.
I ran a speed test this morning on both the wireless and the wired in connection, and have found that the upload speed is very slow on a wired connection. During the speed test with a wired connection I would get 92MB download and only 10MB upload. When I tested this with the wireless connection I got 85MB download and 48mb upload. These were both done with the same laptop. I have run this test multiple time as  I have only recently got fibre. In the past I have had Wired speeds of 95MB / 45MB.
Why is the wired upload now running so much slower than the wireless connection? Any ideas on this?
