Assuming you're not in a country that blocks the use of those channels. There is a bunch of corner cutting gear out there that won't let you use a big chunk of the 5ghz spectrum.

If you're shopping for new stuff look for gear that supports DFS channels in the future.

...and two AmpliFi mesh access points to provide the wifi.

Mesh networks can perform poorly for applications that are sensitive to latency and jitter. (Such as steam's remote play)

a whole bunch of hidden networks come with it. I think this must be related to the mesh network, it's a lot of networks though! 8 or 9 of them

It's possible that some of those are related. My assumption is that there's interference from your own devices and the neighbours. But a mesh network isn't an ideal environment.

In the app, what does the width of the bar represent? It says something like Wifi_Network 157 (155) and has a big flat top that seems to cover a range.

This is indicative of the channel width. It's a common occurrence to have a network use overlapping channels to increase performance.

The take away is that not all channels are isolated from one another and it's possible for a network to have many of them bonded together.

With Wifi_Network 157 (155). It's indicating that the network's real channel 155 with a 80mhz channel width. But it's configured to channel 157 for its beacon as not all devices will connect in 80mhz mode. 157 represents the 20mhz channel it's configured to camp on.

Is that indicating that nearby channels can interfere with each other?

Yes.

Wow thanks for all the info!

Another thought of mine is that wireless devices can perform poorly if they are too close to the AP. (Like less than a meter)

Huh, I wouldn't have thought of that. I'm pretty close! I'll try moving it a bit further away.

Last night it was much more stable, I didn't have any Steam dropouts (only the BG3 crashes which seem pretty common in Act 3 after having none until then, and I'm not the only one). But I do have the option to create a separate non-mesh network from the AP if I need to. If I have further trouble I'll give that a go.

When I changed the channel, the whole lot came with it, hence my assumption.

Channel 165 tends to be empty if you do try that.

If your core problem is bg3 itself crashing then I've gone on a silly tangent here.

You might find act 3 is more stable in dx11 mode assuming proton is up for the challenge.

Two issues here: Issue one, BG3 itself crashes all the time. This most likely isn't linux related, because it's been rock solid up to Act 3 and everyone across all platforms complains about all the crashing in Act 3. Solution - quick save all the time.

Issue two, sometimes Steam Remote Play will disconnect from the game. The game continues to play on the remote PC but the connection is lost, and it won't let me reconnect (which is something Steam normally lets you do, but this might be because it's a non-steam game).

Your info on wifi networks to prevent the connection dropping has definitely been relevant and helpful!

Now that patch 7 has landed has your experience improved?

[–] Dave@lemmy.nz 2 points 2 months ago* (last edited 2 months ago)

Oh I hadn't realised it had! I'll have to make sure I update before I play again.

The release notes seem to cover lots of specific crashes, but I'd guess my issue is more generally that if it's trying to shoe too much stuff on the screen (like a crowded city) then it crashes. I have turned the graphics settings right down and it happens less, but still happens at least once each time I play. I'm keen to check out that patch and see if it helps. Thanks for letting me know about it!
