X870E Taichi Lite Ethernet Issue

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

   Guys I had same problem with my X870 Taichi. One day suddenly my LAN stopped working. No solution would work, I ended up buying USB->Ethernet dongle.

Some time later my Bluetooth stopped working, just gone from system. Tried all, reinstalling, BIOS etc. All seemed fine but it just wasn't there.

AND!

I found a solution in a different topic on this board by someone using older board years ago.

THE SOLUTION IS:

Unplug the power cable completely, leave the PC for a couple minutes like that, discharge all that might be left. Then reconnect the power cable to PSU and both LAN and BT are back!

	According to the Realtek - Ethernet Diagnostic Utility under Cable I have varying wire pairs that are shorted, open or normal when (good)cable is connected and pairs 1-2, 3-6 short and pairs 4-5 & 7-8 open when no cable connected. Had it automagically fix itself for a few hours then back to not working. It connected at 100 and had only one pair shorted then all went normal and was @ 1000. I'm running 1126.21.903.2024 from Realtec website for the RTL8126.

	Same issue, motherboard installed on Nov 25, 2024 , ethernet port working no problem by Dec 5th, 2024 the ethernet port does not connect. Checked the network cabling with other devices all work but no activity lights when plugged into the X870E ethernet port 5G. Using WiFi until I find a solution, must have been a patch or update, as it was working.

	I bought an Ethernet Switch, and the problem is solved... ASRock owes me a gift card. https://www.amazon.ca/gp/product/B0C64N2QN7?ref=ppx_pt2_dt_b_prod_image

	You?�re going to love me for this?? Try this following https://www.reddit.com/r/buildapc/comments/tft3u0/is_realtek_25gbe_lan_issue_fixed/ Note that this fixes it completely for me I don?�t advise turning off flow control however. It?�s the other crap defaults which Realtek set on this card which makes it impossible to connect any other decent network device.

	I have same issue as well LAN not working, very fresh windows 11 install with drivers from Asrock site, I think it broke when I connected front panel sound, because I didn't manage to get sound from back panel.
