One major AAA game update will likely break your connection for hours for all intents and purposes.

Bitrate of a 1440p youtube video is going to be around 20mpbs (±4). Your 50 down connection couldn't handle more than 2 streams. The lowest reported bitrate is 16mbps on their support page (https://support.google.com/youtube/answer/1722171?hl=en#zippy=%2Cbitrate). 50/16 = 3.125, with network overhead you'd be VERY lucky to get 3 streams going without stuttering.

It's entirely possible that a family of 5 would run into issues if they're all home and some want to watch videos.

My family of 4 have been Plex trained... So I mitigate a lot of these problems personally.

But it's more likely that the 10 up breaks things even more. One person in the house uploading anything (or participating in zoom/teams/etc calls) will cripple your ability to make ANY request to the internet.

You are describing symptoms of bufferbloat, not capacity problems.

No... I'm not. Downloading a 100GB game from Steam for example will gladly eat the full 50 mbps this person claims is "usable". A 100GB download would be ~4.5 hours at full speed. With ANY amount of overhead it will be more than 5 hours.

A download saturating the full connection is a capacity problem.

To the second point... If you are on a zoom call and are uploading the full 10 mbps of your connection speed. You will have problems uploading requests to fulfill for download.

Both of these are capacity problems. Not bufferbloat. Quite honestly, this capacity problem can CAUSE bufferbloat. There will be excessive queuing and packet loss.

Multi-hour downloads have been a thing since capacity was measured in kbps. If a simple TCP transfer causes excessive queueing, then the queueing algorithm is broken.

A router with OpenWrt and luci-app-sqm can fix this problem, at least for an internet connection with a fixed speed limit.

LMAO. No. This has nothing to do with a router. TCP is a "fair" protocol. https://www.geeksforgeeks.org/tcp-fairness-measures/

How you can argue about this stuff and now even know how it works... beyond me.

A steam download (which tends to open multiple TCP channels, thus choking other connections on a network)... That's taking 50 mbps + your youtube video that wants to take 7mbps. 50+7 = 57 which is > 50 mbps. This is literally a capacity problem.

Once again... It would be the fact that you're using more than your actual bandwidth that you would cause excessive queueing and thus have a bufferbloat problem. But simply switching queueing mechanisms won't resolve it. especially if you're using traffic that isn't prioritized. Nor does switching queueing mechanisms mean that the problem was bufferbloat to begin with.

Well, if you currently have this problem and want to fix it, I've shown you the way. OpenWrt is free software.

Otherwise, there's no point arguing about it.

OpenWrt can't magic extra bandwidth in your pipes.
