I have noticed after a few updates my ethernet transfer speeds have significantly dropped, with my USB C to ethernet adapter I used to be able to transfer over 600mbps over ethernet but now it's dropped down to 92mbps also I noticed on wifi when transferring for the longest time I have always been capped to 50mbps but the main issue here is the significant drops in ethernet transfer speeds

Steps for reproducing this issue:

Install a game and do game transfer to my Steam deck via ethernet

Scratch that, apparently my ethernet defaulted itself to 100mbs for some reason on my PC os I unplugged the ehternet cord and re plugged it into my PC

Before this said 100mb's but now it's showing the full proper 1000mbps speed

I guess if anyone else runs into this issue make sure that the wired connection is showing the correct speed and can use this as help to solve the issue
