Hello. Recently I've updated from 384.18_beta1 to 386.2_2. Since then I'm getting massive lag spike on my normal setup that shouldn't be there.

Setup: TCP OpenVPN with Strict Policy Rule that forbids internet access without VPN, Dual WAN (50/50 and 100/100), Cloudflare DNS.

After updating my dl/ul speed plummeted to 20KB/S, ping started to rocket up to 600, which isn't a problem on my VPN (checked it on my ISP router, then fully disabled VPN and switched to the second line - same issue).

Downgrade to 384.18 and full reset didn't solve a problem.

Here's a small portion of my log:

May 5 23:58:52 kernel: nvram: consolidating space!

IIRC, when everything was OK, there was no dnsmasq and kernel inside the log. DNSMasq probably means DNSCrypt, but I don't have that enabled.

I'm struggling with this for a week now. Looking forward to a solution.

I am using 386.2_2 and I've been having lag spikes too, I never thought it could be from the firmware itself, I believe you got a point. I hope Merlin checks this out.

Those are all normal events....your desktop renewing it's lease, and the nvram statement performing housekeeping.
The TLS event should have been followed up with the openvpn client reconnecting (I'm assuming you filtered your post).

I reverted back to this version 9.0.0.4.386_41994 and everything is stable so far. My game is running fine. I lost the VPN feature, however, as long as my game is running without any lag spikes, i'm good.


Thank you.
