Model: ER605 (TL-R605)  
Hardware Version: V2
Firmware Version: 2.3

Hello, I have noticed that since installing the latest firmware 2.3 VPN speeds have been cut in half. Wireguard previousely 120mbps OpenVPN 20mbps  Is anyone else experiencing this. Just to test I purchased another ER605 and installed the previous firmware. The previous speeds returned. Rolling back the firmware or trying to install the previous one failed so i had to resort to buying a new router.Has anyone else noticed this? or any suggestions

I can confirm, All VPN has significantly lower speed.

 

but it is not necessary to buy a new router to downgrade :-), log in to the router with SSH and type enable, then roll-back

Just Upgraded to v2.3.0 firmware HardWare v2.0

NAT on L2TP VPN Client not working anymore, Very high CPU, I had to rollback to v2.2.6 firmware

I might needed to hard reset and config all manualy

I have a ER605 hardware version 2.20. firmware 2.3.0

There is a IPSec VPN tunnel between ER605 and Linksys LRT224.

The VPN speeds are matching the 50/10 Mbit of the LTR224 internet access limit. But sometimes the speed drops down to 20 kbit. After reboot of the ER605 the speed goes back to 50Mbit.
