There are 2 issues here that are mixed together. First is WiFi disconnections with the Steam Deck just sitting idle or usage without game downloads (e.g. browsing the store) and the second is WiFi disconnections when downloading games. Please test the two different scenarios listed above and report back on WiFi disconnections with this OS version. For the first scenario, let the Steam Deck sit idle for ~2 minutes between browsing and see if you get any disconnects. If you were having disconnections before, please try to provide an assessment if it's any better with this OS version.
If you still have disconnects, please provide the country you are in, AP make and model you are using, 2.4GHz/5GHz/Auto band, 20/40/80MHz/Auto bandwidth.
Doing the same download on the 2.4Ghz band works without issue (however download speed on 2.4Ghz band stays around 2-3 MB/s).
For my network setup, I'm using a set of 3 AmpliFi Router HD mesh routers (2 acting as mesh APs to the router over 5Ghz), Hardware ID 19, firmware version 3.7.1 (up-to-date). I'm connecting through a Nighthawk CM2050V modem to Comcast cable. Main router is in my basement, two Mesh APs on opposite sides of my main floor (one of which sits about 5 feet from my Steam Deck). Both APs have good signal to the main router (the one the Steam Deck connects through is showing signal level around -50 to -55dBm).
As a workaround for daily use and for testing purposes, I have also created an additional SSID for my 2.4Ghz band on one of my main floor APs, and direct my Steam Deck to connect directly there to avoid disconnects (albeit much slower overall!).
I have MANY devices connecting to both APs and to the router directly with no issues on the 5Ghz band.
Router Wireless Settings:
I started testing with power management on and tests results were inconsistent.
The first time when I let deck sit idle it got disconnected from wifi (wifi icon went grey) and I had to reconnect through settings. After that I could not reproduce same issue.
Later I did some more tests and although no disconnects happened when idling, I got "Cannot reach steam servers" error when actively browsing (with wifi still connected and exclamation mark on wifi icon). Did more tests and also couldn't reproduce this issue. I suppose this is related to second issue.
Generally as soon as I start download I get exclamation mark near wifi icon and cannot reach steam server error in settings. Usually turning wifi on/off fixes it, but sometimes I need to restart device. Connection issues happens when downloading games, deck updates, but also when downloading through browser. I also got disconnects when using moonlight/remote play or when booting during shader cache updates. I did not get disconnects when downloading large files over lan (though this contradicts moonlight/remote play case so further tests might be needed here...)
List of things I tried to resolve the issue (probably incomplete):
- IPv6 on/off/ignored: doesn't help
- Wifi power management on/off: doesn't help
- Setting fixed channel width 40hz: disconnects happens, but gets delayed
- Download speed limit 140000kbps: disconnects delayed, but usually was able to use device without problems
- Wifi 2.4GHz: disconnects doesn't happen when downloading (slow), though one time connection dropped when I was remote playing
- Setting driver options (found on other forums): doesn't help
- Using alternate driver: this seemed to fix the issue, but after deck update when I tried to install it, my deck got bricked and I had to reimage it, so I stopped using it.
- Tweaking various settings in router, dtim/beacon period, mode, channel, upnp, port forwarding etc.: doesn't help, settings related to download speed delay the issue
- Setting up hotspot on my desktop: no disconnects, reaching speeds 50MB/s
- Using different devices, arch linux steam downloads: no disconnects, win10 steam downloads: no disconnects
It mostly happens on non-throttled 5GHz network when download speeds reach 20MB/s (though this is not a rule). Up till now I mostly got around this issue by limiting download speed to 140000Kb/s, but on this new build even this stopped helping, so something must have changed. Upon further testing I found one interesting correlation. On 80Hz I get instant disconnects, but on 40Hz my connection is more stable and I am able to download few gigabytes (avg 18MB/s), before eventually losing connection also. But when I move closer to ap (I am testing in another room), the download speed starts ramping up (up to 30MB/s), and disconnects happen faster.2) working fine on WiFi X and not on WiFi Y is an unfortunately classic behaviour for the SD:

3) can you report your situation following @resibik's instructions?
Edit. Turns out it is just guild wars 2 being horribly slow for updating.
Hey resibik, any updates to offer? Or any other troubleshooting affected users can do to speed along a resolution to this?
I have already split my network into a separate SS for 2.4Ghz and 5Ghz. Same issue for both.
Initially on stable I had segfaults in kernel on iwd (the kernel module that manage wireless connections on LInux on which the specific realtek driver attaches) expecially when downloading large games/using significant bandwitth. Other times it would start at AC speeds (2.5 gbit user, around 30/40 MB/s), and after 10 seconds get cut to max 10 MB/s (2.4 Ghz channel speeds). Switching off power management had no influence.
After that I swiched to preview and the segfaults were gone, but I had this issue for a while in semptember, where there were no crash on iwd but steam would randomly stop connecting to the content server, even if the connection was still fine and I could browse community and such from the UI. The only fix was to toggle off and on the wifi, but that would fix the issue only if I would not download anything from Steam, otherwire that would come back after 10/30 seconds. it was extremely annoying and rendered the device basically useless. Then the issue disappeared ageain.
Again around end of december the problem popped up randomly, but just for a couple of days. I have serously no idea what the problem of the deck is, expecially since my laptop on Linux had the same network adapter, RTL8822CE, and on the same network never had issues to speak of. It wasn't amazingly fast (that is why I have switched to a AX210 module from Intel), but it was working fine. Mind you that I have used with Linux 5.17 to 5.19, which is more recent than the Deck 5.13, so maybe this will also be an issue of the past when Valve will switch to Linux 6.
Just my two cents,
Marco
Why is valve not using the latest os?
Main issue is probably custom drivers not yet upstreamed to the latest kernel. There is already a build for 6.0 in the repos from the last two months, but it's still not the default. People have already tried to switch to that without much issue. Probably it's not far long down the line before it will be swapped out.
guess its the waiting time! I have been lucky and wifi connects on my end 95% of the time. Speeds are horrible but at least it connects.
