Slower internet after i changed same cable network to fiber cable

[osiakmarcinartur 0]

Hello,

do you know maybe what can be a problem....

last time i had visit of technicans from internet service and they installed me a new faster cable fiber. Same company same connection but through fiber.

I`am connecting with wifi router which should be good (always was, i was nothing chaning in router or computer settings). After that time i have problem with speed and ping is much slower when i use iternet through AIRVPN example were should be 30MB/s i have just 7-8MB/s. Also it depend to country to which i connect ofcourse but always much much slower.

 

Before there was no problem....with it older standard network cable "non fiber".

When i use internet without VPN speed is 100% as should....so maybe you have any idea for it????????????????

 

HELP
