hi so recently my pc started to disconnenct or get very low speed 15_20kbps if i connect my phone to wifi and now when i have both connected some weird things happen ,for example i get very high ping for no reason ,games show that there is no connection while the browsing is fine ,or sometimes everything shows no connection except chatting services eg messenger

they are both connected wireless so they could interfer from one to the others try to use pc with lan cable .

check your router for overheathing and could you try to use another port on router for the lan cable from pc the last option would nbe to check you lan card in pc
