Understanding upload/download speed?

[Subotai]

Oh Great Gurus,

Riddle me this, Batman. I have a Netgear C7800 that is rated 1000 MBPS and Docsis 3.1. I'm paying for the Go Super Fast plan of (up to) 1 GBPS from Cox Cable. Additionally, Cox just ran some new cable from the street and installed 3 new splitters to rectify a connection problem and remove non-approved spiltters (my bad).

On Speedtest, I'm getting 271 MBPS download speed and 106 MBPS upload speed. Cox Cable's speed test says 362 MBPS download speed and the same upload speed. I would have "thunk" it would be faster. I should get close to 1 GBPS, right? Right?

Why for, pray tell, is it not faster?

I'm not a guru, but your getting cheated. What is your computer capable of?

[Marauder2003]

Is the PC cable connected to the 8700?

Is there any way you can get the 8700 connected to the cable where it comes into the house? Before any splitters.

advertised speeds are not guaranteed

Is there a difference if you use ethernet instead of the Wifi?

How are you testing it? If you are on wifi, plug in a hardwire. Also, try a couple different devices if you can. You might need to run something like TCPoptimizer on a PC to tweak your network settings.

Just got 436mb on my laptop. Will try a wired connection. So, not too worried about it. Thanks for the help!

I have 1gb service from XFinity, nothing connected to Ethernet directly and I get this speed all the way at the end of the house from where my wireless router is:

Absolutely, directly connected via Ethernet you should pretty much get the rated speed your paying for. If you are right next to your wireless router you will get close to it, but across the house and any distance away from the router the speed will decrease based on that.

There are a number of reasons it could be slowed down.

1. Are there any other users in the same domain? They get some of the speed.
2. DOCSIS 3.1 is old. If you want max speed, get a newer modem.
3. What kind of cabling do you have? Ordinary Cat 5 cable spec is 100 mb/sec.
You're lucky you're exceeding that. Standard cables used to be 10 mb/sec.

True but my point was if there was a very large difference, he might be getting interference with other wifi routers.

To truly test the speed that Cox is selling you you need to do so as close to the connection as possible. I have not used that Netgear router but most modern routers will let you test the connection from the routers console. Essentially, you are doing a speed test from the routers OS. Look for a menu or feature on the Netgear console (your internal webpage where you configure it) that discusses connection. I doubt you would get 1000 mbps download but I would imagine that you should get close, say, 900 mbps.

If you test the speed from other devices on your network you would then be limited by the connection speed of those devices. Do you have a device connected via Ethernet? That should be just as fast as from the router, or just slightly slower. But if testing from a WiFi-connected device then you will see speeds much slower because now you are dealing with WiFi signal, WiFi versions/protocols, plus the limitations of the remote device.

But you know, even if you get 200-350 mbps from a WiFi device that is plenty because you will never notice anything by having a faster speed as long as you are just doing basic browsing, streaming, listening, etc..

Most people get confused between Mbps and MBps.

[Iknownot]

I’d make sure the firmware on your modem is current.

Aside from that I recall actual real world cable speeds is dependent on how many different users in the neighborhood are on the same line as you and also the quality of the line as well.

Generally speaking download and upload speeds aren't advertised as the same on cable systems. This is to save bandwidth and because most home use is just on the download side.
