Edit: at risk of preemptively saying “solved” - disabling the QoS on the router bumped the desktop browser speedtest from the ~600 up to >950Mbps.
My internet plan with my ISP is for 1000 Mbps. This is far more than I need almost always, but it is what they say I am paying for. However, I can’t get any speed tests to read more than ~650 Mbps, which is around about what my old package was.
My router itself has a speedtest functionality and that is what I’m getting off of that. As I’m writing this post, I did a speedtest on my wired-in desktop and got ~590Mbps on speedtest.net.
One thought I had was that maybe the ethernet cables themselves are the limit. All of them say ‘cat5e’ (actually, just checked and the modem-to-router is cat6), though, which should be 1000Mbps, yea? I swapped out the cable from the modem to the router once and got the same speed with the new ethernet cable.
Maybe the router is just too weak? Well, I used iperf3 between two desktops that are both hardwired in and I got ~940 “Mbits/sec”. Unless I’m messing up the unit conversion (which I certainly am annoyed by the difference between “megabytes per second” and “megabits per second”), that is the 1000Mbps that I’d expect to max out the ethernet cables. So, since those two machines are going through the router, it doesn’t seem that the router is the bottleneck for my speed to the great outdoors.
The modem? The modem’s specsheet says it can do 2.5Gbps (well, actually I assume there is a funny typo - it says “10/100/1000/2500 Gbps RJ-45 port”, but I don’t think it is doing 2.5 terrabytes/bits per second). The little led on the modem is lit up the color for “an ethernet device is connected at 2500 Mbps”.
So, should I start hassling my ISP about my missing 350 Mbps? Is there some other obvious thing I should test before I hassle them? I certainly don’t want them to say “have you turned it off and on again”? (once I wrote that, I did go and unplug the modem and router, stand around for 30 seconds, and then plug in the modem and then the router. after I did that, I got one speedtest from the router at 820Mbps, and then the next two tests are back to ~550).
Edit: I do not have fiber, I have a coax cable coming into the house. The person trying to sell me fiber said “your current internet is shared with the neighbors”.
Let’s back up just a moment - is there an issue you’re trying to diagnose, like bad lag, packet drops, excess ping, etc.?
If not, then don’t worry about the speeds too much unless you feel like you’re being overcharged.
That is the correct question, and mostly no, I don’t have any specific problem.
The biggest motivator for me looking at it is probably just hobby/interest/how-does-this-work.
That said, my partner and I both work from home ~50% and are often pulling files/data that are a couple GB from the work network, and having those go faster would be nice. Probably the limiting factor in those, though, is the upload from the work network and so faster download for us likely wouldn’t matter, but I’d like to be able to say “I looked into it, honey.”
there will be some bandwidth aggregation, so the speed is perfectly fine from the contract point of view.
second, 1 gbps on network layer is not 1 gbps on application layer. in other words, only part of the data that you download are actual useful data - there is some overhead.
at such speed, there is no such thing as “internet speed”. there is speed to specific source at the specific time. your provider can only guarantee so much. your source being able to push data to you at the speed your last mile might be able to receive them is not among the guaranteeable.
complaining that your internet only does 650 mbps really is first world problem.
