Question

Hi,
I have configured OVPN tunnel connection between my PC and RUT955. Both devices are operating in wider local subnetwork.
Unfortunately my bandwidth is very poor - below 2 Mb/s:

  Other types of VPNs achieve similar performance. Is there any option to increase it? My connection parameters looks very decent. 
RRSI: -50 dBm
RSRP: -80 dBm
RSRQ: -14 dBm
SINR: 12.6 dBm

Hello,

RUT955 does not have a very fast CPU, thus its capabilities are limited. Despite the decent mobile signal indicators, mobile itself requires resources, reducing the overall performance. It is also dependent on the authentication/encryption methods chosen, more complex ones require more processing power. The suggestion could be to disable any unnecessary services, if you have any running.

Best regards,

Hello
It does not help. Only OVPN with static key encryption is activated. Router was reset to the factory settings and only OVPN settings was modified. Pretty all services are disabled. If I tried with other VPNs results are similar like less then 2.5Mb/s. Even without any VPN it is still very bad. Slow CPU shouldn't  have that huge impact.

For example when I tried Wi-Fi connection the speed was standard like 80Mb/s.
I also performed some additional tests:
- Changed router to RUTX14, used auto APN and proceeded Speed Test available in System tab, results: download 5.64 Mbps upload 4.34 Mbps
- Put SIM card in my personal phone and achieved 19 Mbps
