Ethernet Extremely Slow (Not On Windows, Only In Bazzite)

Just today I have switched to Bazzite (good riddance Windows 11). I have nothing but Bazzite on my drive. Not dual booting. I notice my internet speed (wired ethernet) is extremely slow compared to being on Windows. On Windows, previously it was 20+ MB/s (still slow, but bearable to me). I am sure I am not downloading anything else. Please help, there must be something I can do about this. I know it's not because of hardware, the only thing changed was that I flashed Bazzite. All the cables and hardware stuff are identical.

Solution:

Are you sure your not confusing MB (MegaBytes) with Mb (Megabits)? 4MBps is around 32mbps (8Mb=1MB)...

If it helps, the network device name is enp6s0. My setup can't have wireless, because the PC is in a room far away from router, and I am using powerline adapter internet.

Is it only behaving that way on Steam or on non-Steam apps too?

I'd look up who makes your network card, see if there's a firmware or drive update on their website. or try a USB to ethernet adapter, see if the speeds are any different

non-Steam apps too I show the Steam because that's how I noticed I've also disabled metered connection Before I disabled it it was kB/s This is what it says:

I saw that Bazzite is immutable so installing the updated driver (if I found one) is not the usual process, can you tell me how to properly install the driver if I find it? I'll also look for USB-to-ethernet adapter Thank you two for the interest in my peril Additional info:

ETHREAL1•4w ago

So could be that you are reading windows in mbps, and Linux is MBps? With that said, I’ve not noticed anything on my end assuming it’s not some HW issue

txt•4w ago

Also new to Bazzite so I am not sure if this will help or not. Have you tried setting the Link Negotiation from Ignore/Manual to Automatic in Configure Network Connections? Restart your connection before checking it again

DoryToesOP•4w ago

Aw man yeah I was, oops My settings seem good rn, back to normal speed It's true that originally it was very slow though, mostly because of the metered option If it helps anyone, these are my settings and they're able to get my speed back to normal (for wired connection, powerline adapter):
