Download speed really slow on Deck

[Mayor Humdinger]

The max download speed I get over wifi currently is about 2 MB on my 350 Mbit line for downloading games in Steam. The weird thing is that I am pretty sure that when I got the Deck it went almost full speed, it has gotten worse the last few days. If I run speedtest from Chrome on the deck it also shows my full speed. I was thinking that it might be a problem with the SSD, as some of them can get slower when almost full, but I have ~60GB free, also 2 Mb/s would be really damn slow even then. Anyone with any ideas? (it's also not the Steam dl region)

Update: its not the wifi, because it is just as slow with wired LAN and it really is only Steam.

Update 2: this might be an RMA, its the same (kinda worse tbh) after factory reset

Update 3: I was about to bring it over to a friend to try with on another network, then I had the idea to remove my Pi-hole from my network and now I download with full speed. I have no friggin idea why this caused the aforementioned issues. Now i just need to figure out what to change in the Pi-hole, cause i still wanna use that too obviously. Moral of the story: always start troubleshooting with testing in another network.

Did you ever figure out what to change in your pi-hole I am having the exact same issue and was wondering why when i hotspotted to my phone it was better than my wifi.

I have no issues, everything downloads really fast over wifi.

Nope.

I also removed my network wide pi-hole ad blocker and set it up so that individual deviced would use it within my asus router settings but letting the steam deck go straight to 1.1.1.1 or whatever. Now download speeds are as i would have expected from this device on wifi.

If you have any issues with Wifi, try using a USB-C to Ethernet adapter (or a USB-C dock which has an RJ11 port (ethernet) on it) and manually plug your SteamDeck into your router or network switch or whatever device your using to connect to the internet and if your still getting connection problems, you may need to go directly to Valve's support page to see if they can fix your problem...

not really

Hey, received my Steam Deck today and noticed a slow wifi while downloading ( 2-4 MB/s )
Easy fix : Enable Developper mode and then disable "Wi-Fi power saving mode"

Immediately fixed the wifi speed, downloading at 40MB/s now...

Enjoy :)

Not really the same issue as OP since he found a "fix", but my wifi is really slow (7/8MB/s) if I use my 2.4GHz network.
I could download at 40/50MB/s with my 5GHz network but the connection instantly drops after 10 seconds, every time. on every channel. Which makes the 5GHz unusable on my Deck (which is the only one that doesn't maintain a healthy connection with the 5GHz network).

So... Here I am with my slowbutt wifi, trying to download 50+GBs games... :(

Steam is aware of my issue though, but still no fix or whatsoever.

I did not have this issue, but for sure the WiFi in steamdeck does not works properly. As I said in other thread, most time I turn off and then on the WiFi, it does not connect... always the same results, the only way it is to Lea è always off. If you experienced issue in slow download, tra to turn off and turn on the WiFi, or if you share the network data by a smartphone via tethering, try to turn off and on also on the smartphone.

For what it's worth, I too had a huge speed problem- and saw others mentioning DNS issues, PiHole, other things along that line. I thought that can't be it, but I do have a local DNS cache on my opnsense firewall (unbound). So I removed that, and made sure DHCP gave out only 1.1.1.1 and 8.8.8.8 as DNS servers.... once I did that, the Steamdeck would download at full connection speeds for me (about 10-11mb/sec).
Hope this is helpful for someone (another suggestion is to make a new dedicated wireless SSID in a walled-garden with custom DNS of 1.1.1.1 and 8.8.8.8- that works too)

The quickest / easiest work around for me was to
* switch to desktop mode
* open the kwrite program from the start menu on the desktop
* open your /etc/resolv.conf and change the first entry to the IP of the nameserver you want to use and save the file and then you can switch back to game mode and be gtg until your next reboot
for example:
Old:
nameserver 192.168.1.1 (or whatever your pihole IP is)
New:
nameserver 1.1.1.1 (or whatever your ISP or preferred DNS IP is)

You are a genius, this helped me. Went from max 2Mbps to 24Mbps.

It also makes sense, it would start insanely speedy and settle down quickly at max 2Mbps. It had to do something with the WiFi adapter itself.

*Edit* So after 5 minutes or so it was back at old snail speed.
Tried to open `/etc/resolv.conf`, it showed a weird primary DNS server changed it to my router. Now my download speed is correct again, it's 33MBs

I was setting up two Decks at once side-by-side (one for somebody else, I'm not greedy). One of mine was going in the hundreds of K and the other was going under 1 K. My internet speed is 1Gbps. So not only were they going slow, but one was going way slower than the other.

I tried switching the region for downloads. I tried using dev tools mode to turn off wifi power saving. I tried plugging into ethernet by wire. None of those worked.

What worked for me was setting my router DNS to defaults. I had the DNS set for PiHole. I'll have to figure out that one later.

Hey! Thank you!

No worries. I ended up just configuring my pihole to use my ISP DNS instead of the OpenDNS and I haven't had trouble since. The main reason I use pihole is to mandate all devices use the StevenBlack hosts file/blacklist and not because of OpenDNS so that may or may not be useful to your use case ...
