since about a week or so i´ve been getting mad choke/loss in tf2 and csgo up to 80. My ping is fine, my donwload and upload are all cool aswell(can dl stuff as fast as it has always been, can watch yt 1080p60fps etc.)
I called our ISP and they said everything should be working fine.
Already tried: reinstalling steam/tf2/csgo
unplugging my router for multiple minutes

Also, a week ago or so it only was like that for some time periods, so it was fine after i waited it out, but since today it was unplayable for the whole day

thx for reading, help is appreciated.
