Ethernet speed on S22?

I’m trying to troubleshoot the Internet in my apartment but am limited in the devices that I can use to test Ethernet.

Wondering what the rated speed on my S22 is over ethernet, and having difficulty finding anything online.

My home Internet is supposed to be 500Mbps symmetric but I’m getting 94Mbps up/down when connected to my S22 directly with a gigabit Ethernet to USB-C adapter.

Can anyone help me find out whether this is a limitation of my phone? Or is my home Internet actually messed up?

Could be a bad cable, one dodgy wire in an ethernet cable will drop you to 100mbit link speed, or it could be that your adaptor isnt actually gigabit, or the port you are plugging into isn’t gigabit.

I’ve used a USB3 Ethernet adaptor on a Samsung Note9 and a Fold3 and both supported the full gigabit sync with the expected speeds for a cheap usb ethernet controller.

I’d bet that you’ve got a 10/100 adapter and not a 10/100/1000 adapter. Manufacturer saves a buck but they’re not very useful anymore. Try it in a laptop and see what you get

94 Mbps is basically exactly what you can get from a 100 Mbps connection after overhead. 93-95% or so of the theoretical maximum. Something's wrong and you're getting a 100 Mbit/s connection.

Are you particularly trying to test Ethernet? I can get 500 Mbps speed tests over WiFi from my phone pretty easily.

I would start with the adapter itself. Many times the cheaper ones are crap.

yeah, at ~100mbit speed tests you almost certainly have a bottleneck somewhere. 100mbit ethernet adapter is a good place to check. Also verify the ethernet cable you’re using. I’ve found some “cat 5e UTP” were missing the “twisted pair” part and that prevented it from reaching gigabit link speeds. The next is any switch you may have in line between phone and router. Next is the router. If the router has 100mbit switch ports, you’re bottlenecked no matter what you plug into it.

Are you getting 94Mbps or MBps? If it’s the latter then it should be fine.

Do you have another device you can test the Ethernet adapter on?

Cralder ,

It wouldn’t make sense for it to be MBps since that would mean his internet speed is way higher than what he pays for.

Borrow a laptop with ethernet port from someone
