TL-SG105E changes 1000mbps to 100mbps
Hello!
My TL-SG105E changes the speed from 1000mbps to 100mbps randomly. I looked already for similar problems here and found some solutions but they didn't help. I changed the cable 3 times already, but nothing helped. The connection went to 1000mbps after unplugging everything and recable it, but it works only for a few hours to a few days.
My router setup is fine. The lan port got full speed and no eco mode is activated.
Thanks in advance
Edit: The switch is in use since 07/23 and it worked fine for like 4 months. I changed nothing in that time. Will do some further testing. I put the whole setup to a different location in my room because i need to use the lan ports in the wall. Directly wiring my pc to the wall works fine and is always at 1000mbps, so the cables in the wall shouldn't be the issue.
