Can't update both clients + new client refuses to connect until in game

This is an issue I've been having since the new client came out, though nothing much has been said on it. Used to be able to play just fine, but ever since that patch came out my client can NEVER update. It ALWAYS gets interrupted due to some error and has to start all over. This happens whether I'm on the legacy client or the new client. The new client is what I really want to stick to, but it won't work either. Every few seconds if I'm not clicking around in the client it disconnects and won't connect again for about 10-15 minutes even though my internet is perfectly fine. Some things to note:

• I can't patch at all without sitting through the 1 hour patch just clicking in the window to keep it connected
• The new client will not update the game properly and keeps disconnecting and restarting (will show a percentage where the play button should be, then it says the internet disconnected even though nothing happened at all according to my computer)
• Everything is TOTALLY FINE (usual ping of 50, 60 fps, no connection issues, the good stuff) once a match begins, but I kind of need to be able to update to even get to that point
• If everything is updated, connection fades in and out every minute or so unless I click around in the store/collection/other areas of the client. Please help resolve this issue. I've been submitting bug reports every so often in hopes it will be fixed so I can finally come back to the game. Anyone else struggling with this? TL;DR: Can't patch, can't play, though nothing on my end is ever wrong and the game itself is fine. The client is just being difficult.
