Troubles after upgrading 2.9.38 to 2.9.46

RouterOS Beginner Basics
1

Hi there!

We’re having some problems since our transition from 2.9.38 to 2.9.46 RouterOS (AMD). Internet Browsing is pretty slow, we’re experiencing loads of timeouts (DNS, Ping timeouts, pages not loading, MSN not connecting).

To upgrade, I’ve just copied the update file to “Files” window and reboot the machine :neutral_face: Is there anything else I should have done?

It was just working flawlessly before!

Just added those rules (the machine acts as a PPPoE server) but problem persists:

/ ip firewall mangle
add chain=forward tcp-flags=syn action=jump jump-target=mss comment="\[tcp\], mss" disabled=no
add chain=mss protocol=tcp tcp-flags=syn tcp-mss=!536-1460 action=change-mss new-mss=1440 comment="\[tcp\], mss fixation" disabled=no
add chain=mss protocol=tcp tcp-flags=syn tcp-mss=1453-65535 action=change-mss new-mss=1440 comment="\[tcp\], mss 1440 for mtu 1492" disabled=no
add chain=mss protocol=tcp tcp-flags=syn action=change-mss new-mss=clamp-to-pmtu comment="\[tcp\], mss clamp-to-pmtu" disabled=no
add chain=prerouting action=change-ttl new-ttl=set:65 comment="\[tcp\], mss ttl fix" disabled=no

Please help :neutral_face:

Wireless or hardwired connection?

Wired! Rolling back to previous version (2.9.38) fixed the problem, but again, I would like to know what was wrong :neutral_face:

I would suggest upgrading the OS, create a support file and email to support@mikrotik.com with the problems you are having. Roll back to the older version until you have heard back.

That’s what I will be doing in few days, since I’m on a production machine :slight_smile:
