I previously used the AC1750 with a TL-SG108E and had no issues. I replaced the AC1750 with an AX73 and although the two PC's connected to the switch can get an IP the connection is slow and according to my teen, gaming audio is choppy.  No changes were made to the PC.  I've rebooted the switch, router, modem and still have issues.  I ran the Windows 10 troubleshooter and found no issues.  I don't have anything set on the smart switch other than auto-negotiate. I've tried changing the DNS from Open DNS to the default Cox DNS and that didn't help. No other issues with connections (well, Wi-Fi kept turning off when using Smart Connect so I turned that off and no issues). I think it's switch related but I just swapped routers so not sure what the issue could be to cause slow internet on the PC's connected to it.

Any ideas?
