Slow Internet after CU 200

Please Help

Since the last Core Update 200 , my internet traffic went bad! i dont know why but internet is very slow and needs to restart the FW to get it better.

Is there a way to roll back to previous core ?

every recent core update worked perfect. i need it back

please help

How do you notice the differences?
There’s no reason for the traffic to be slower. The changes are primarily to the Linux kernel, Suricata, and the IPFire DBL lists.

Before considering a rollback, it would be best to analyze the problem, check the logs, etc…
To roll back, you will need to reinstall CU199 and restore the backup that was made before the upgrade.

Iv checked but there is no system logs that indicates for somthing .

kernel upgrades can affects the communication with the hardware, so it possible that my
FW hardware ( HP ProDesk 400 G7 dekstop ) lost performance ?

Anyway.. i really need the roll back, how do i get it back exectly ?

thanks

System → backup

1 - download the last backup file
2 - Réinstall 199
3 - restore the downloaded file

iv downloaded the last backup, but how do i reinstall core 199 ?

You have the option of downloading an ISO with all your settings and then reinstalling IPF using this ISO. See this KB article:

From ISO or Backup ISO.
