LAN Problems with B550 Extreme 4

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello Asrock-Forum,

I have a recurring Problem with my B550 Extreme 4 Mainboard.

Sometimes (every 2-3 days) my LAN connection to my router just stops working. Rebooting or unplugging ethernet and replugging it helps.

I dont know if that is coincidence, but I only remember that problem occuring while watching youtube videos.

What could that be? I am still on the 1.80 Bios.

	Have you tried a different LAN cable, made sure the LAN port is configured correctly and tried updating the LAN driver?

	LAN driver is the latest from https://www.asrock.com/mb/AMD/B550%20Extreme4/index.de.asp#Download I did not try the other two suggestions. Can you specify "LAN port is configured correctly"? And why should a different cable help? 99% of the Time my LAN is working. I can't imagine that some cable works 99% of the time and then decides that it stops working and starts working again after replugging. Afterall, its just a string of metal ;-)

	Go to device manager > network adapters. Look for your LAN and hit the "Advanced" tab, ensure all settings there are configured correctly. You should also check settings for your router as well. Cables can also become faulty, they might get a slight break in the wire, or if its a low quality wire the cable might oxidise over time affecting functionality, things like that ;o)
