pfSense upgrade to 2.5.2 | now slow with bad latency

I waited to upgrade pfSense at my folks’ house until I visited. I’m glad I did.

I am having an issue with their low-end Protectli box that was working fine with v2.4.x and after the upgrade, it’s having all sorts of latency issues.

The specs…
Intel(R) Celeron(R) CPU J1800 @ 2.41GHz
Current: 2407 MHz, Max: 2408 MHz
2 CPUs: 1 package(s) x 2 core(s)
AES-NI CPU Crypto: No
QAT Crypto: No

Ping response times…

Initially, I couldn’t connect to any web sites at all, after the upgrade. I created a new WAN interface and set it as default and things got better, but not by much. I have tried restoring the config xml file, but did not yet to a full reset, then restore of the config xml file. As you can see above, the ping response times are horrible and speed tests on their 100/10 connection is now more like 30/1.

If you have any suggestions, please share.

Thank you,

All my upgrades have been fine, though I usually upgrade from the previous release.

My guess is something has gone wrong from the update between such a wide range in the releases.

I’d take a backup, then I’d do a clean install to see if there are still latency issues.

Or if you have the option roll back to the last working version you had, then do incremental upgrades up to 2.5.2.

I don’t think there is anything wrong with your box (I have a similar one) or 2.5.2.

You won’t be able to download the previous ISO’s from pfsense if you don’t already have them.

There is a mirror set up, but it is not official, they go back several versions.
