My 350mb connection has been getting worse over the last few weeks on my SH3.

I did have loads of post rs errors but it erased them when I did a reboot a moment ago.

Please could anyone see if there is anything up with my levels?

BTW I'm using a SH3 in modem mode with a Asus rt-ax56u (350mb).

Over utilisation?

Stats look fine but then again you’ve just rebooted. Check them again in an hour or so’s time and see if any error counts rise.

 The red is when I have been rebooting.
