Topic: Problem with Nintendo Switch 2 internet connections on Gigabit plan

Good evening. Hi everyone, first post here. I am having a problem with my internet in general and we are troubleshooting some devices and slow speed. I am having issues with my Switch 2 on wireless and wired. I have a WiFi 7 Gigabit plan. My provider is Spectrum and they have been working on vabirous issues for over a month. This is to address the Switch 2. They tested the ethernet cable coming into the Switch 2 and it is sending over 1 GBPS of signal. The cable is new and the information is definitely coming. However my Ethernet connection has never tested over 300 Mbps. My PC wired on the same router gets about 930Mbps. I am connected via 5G WiFi and have never achieved over 250 Mbps even in the same room as the router. The router is capableI have seen numbers online for wired and wireless much higher, from the 400s into the 800s. I asjusted MTU, IPV6, etc. according to what I have read. I also realize that I don't necessarily NEED much higher speeds but if I am capable of it we are trying to find out why. I spoke with Nintendo and since they outsourced their customer service in the past few months they are no help and they could not understand what I was asking. I even wanted to rule out a hardware problem so I was able to hook a different Switch 2 system up to my setup and got the same numbers. Spectrum said they had no suggestions but if anyone on here could help I'd appreciate it. Thanks.

That's normal. Switch tapped out around 35-50 Mbps. Switch 2 is about 10x that. But you're never going to see the same speeds as if running a test on your PC or phone.

My NSW2 has internet with same speed as yours, ethernet connected, and caps around the same as yours.

Thanks for replying. I usally got about 33 or so on my Switch 1. I had a couple of screenshots I wanted to add of higher speeds I found online for the Switch 2 and a reddit post that referenced higher numbers but I don't see where I can add a link. I tried to find my answers myself but were stumped when I saw the information I found.

I do wonder whether the speed test on the Switch 2 is the best measure of actual bandwidth. Because when I look at bandwidth usage on my Switch 2 while downloading stuff I can see it's using ~540Mbps (I'm on a 500Mbps plan). But I'm pretty sure I don't see those speeds on their speedtest

Edit: At home and tested it. So yeah, the network tester I get 190Mbps on gigabit ethernet wired direct to the router. But actually downloading games I get 540Mbps. I wouldn't worry about it, the test isn't a proper reflection of actual performance

@skywake Thank you for responding. Just curious, how do you see what you are using for bandwidth to see while downloading?

@figureguy
My router (Ubiquiti UGC Ultra) allows me to monitor which devices and applications are using bandwidth. Amongst the list of other fun dials and gizmos. Entirely unnecessary but useful for stuff like this I guess

That's weird, I have a similar setup (ethernet cable connected to the router) and I did the Switch 2 internal test a couple of days ago, and the result was around 580Mbps, which seems valid since we have 600Mbps internet plan. IIRC the Switch 1's internal test always showed the download numbers to be much lower than our actual plan, but with the Switch 2 it seems to be accurate.

It's still a puzzle for me. I am working with the local Spectrum field supervisor but we have found no issues with the speed we can address. On the Gig plan I got 300 wired yesterday again which seems to be about the average of the highest.

Your Cables from ISP to your Router/Switch has to be gigbit cable verified and your wiring must support gigabit lines to verify all is going gigabit. So what kinda of ISP do you have? Only way is Fiber that can support Gigabit but then the hardware and cables must support Gigabit transfer to insure everything is playing on the same page.

@larausjarod thanks for responding. I did have Spectrum over here looking at the lines. They actually took the cord from the back of the switch 2 and put that into one of their readers. It is 1 GB coming through the ethernet line to the switch 2. I also have the same type of cable coming from the same router to my desktop and the 1 GB cable produces a speed averaging 930 Mbps. So we know the lines themselves are transferring the speed but something gets lost when I plug the cord into the switch 2.
