Few days ago i've experience huge lag spikes (300+ ms) every few seconds. At first i thought it's my connection. Later i've tried to play again but same issue. So i went to update my drivers , windows updates and so on ( deleted my configs to replace them with fresh ones ) - nothing. Then my internet completely disappeared. "Exclamation symbol" showed up on my connection. Tried to back up old drivers , nothing. The next day blown the dust away , reconnected my PCI-e wireless adapter to the pc and my network was solved. But still experience lag spikes in-game. A guy suggested me to track the network usage. Everything is 0-0.1 except CS:GO - 0.4-0.6 on average and 0.8+ on lag spikes. Imo the problem is not with the internet at all but with the game itself. Would like to hear more experienced opinions and eventually solution.
