High Ping only in CS:GO competitive

[GoncaloSilva]

hi guys i have a huge problem that only csgo players will understand (maybe)
when i play cs go casual i have 60 ping(usual for me) and when i play competitive i have 250 usually
this only started happening some weeks ago
i have a 100mbps cable connection and when i play lol i have 60 ping never more
i think i have a hardware problem or maybe my internet provider as it
any clue how to solve this?
