Improve latency ? GL-MV1000

Do you have any tip to improve the latency on this device? or to set the TTL to 112 when using the device as wireguard client?

Ping to google . uk without GL-MV1000
~35ms TTL=112

Ping to google . uk using GL-MV1000 between router of internet provider and my PC without any kind of configuration on the GL-MV1000, just plugged
~55ms TTL=112

Ping to google . uk using the device between router of internet provider and my PC + connected as wireguard client to a home raspberry wireguard server that is on UK
~74ms TTL=117

I installed lm-sensors and the temperature is 50ยบ

Kind regards
