Lost connection to overwatch sever

I’ve been having this problem ever since the new hero venture came out. It hasn’t been an issues before. I’d play overwatch for about an hour and then lose connection but I’d immediately reconnect within that second but I can’t join back in the game rather it be qp or comp. the thing is I know it’s not my network because I would lose connectivity with all my other apps such as Discord but I don’t thats fun part about wifi its like a switch, it works or it doesn’t. So I’ve been looking around to see anyone else has had this problem and I found a few cases of overwatch 2 lowering your speed and duplex Why? just keep it at auto and overwatch shouldn’t be touching it
