Default Internet Speed

I have had Comcast for years and on the 20 down / 5 up speed plan.

Decided to cut the cable and start streaming and wanted to increase the speed. Upgraded to 75/15 to ensure no issues with multiple concurrent streaming devices

Check the speed today on Speedtest.net and speed is still 20/5 consistently

Comcast says use our speed checker https://business.comcast.com/tools/internet-speed-test

Their tool says speed is 80/15

How can 2 tools be so radically different ? Running on the same computer on 2 different tabs of the same browser

Depends on the route and of course they want you to use their tool, you are not leaving their network by using their tool. Try google speed test.

Using the Comcast tool to test the speed of your connection to the Comcast network? Don't trust it! Trust speedtest.net.

Google test says as fast as Comcast

I guess the issue is the server it connects to for the test

Thanks

Try https://www.speakeasy.net/speedtest/ . It may show the same thing but worth a try.

Interesting. I just upgraded to 100 mps service thru Spectrum. I tested it right after and got close to that.

I just tried speakeasy.net from Northern Ohio to Washington DC was 54.8/2.2 Speedtest.net to Washington DC was 53.7/11

Speedtest.net to Petersburg , Michigan was 55.7/11

Not sure why the discrepancy or why it's not closer to 100 mps.

tests done on laptop about 8' away from wireless router. New router hard wired (40') to new modem.

As far as I know, fast.com is run by netflix and as such, is testing the speed to the netflix cache which is probably on your ISP's servers...my belief is that that netflix leases space on ISP servers to ensure fast load times. Other outfits may be doing something similar, thus accounting for the discrepancy between google's speed test and someone else's.

I'm not in IT or anything, I just have to solve similar problems once in a while, but if it were me I would maybe do a tracert to whatever the IP address that speedtest.net is using locally. I would guess that the routing is goofy and Comcast is putting you through something slow when you're stepping off their turf and onto the rest of the world. This is just a guess and others may well know more.

Speakeasy is my preferred testing site these days.

Your ISP guarantees you a connection speed to their closest hop. After that you're at the mercy of the Internet. Comcast gets me 125 Mbps down and 25 Mbps up. I test that and that's what I get. If I'm trying to hit a server in Singapore I may go through 20 hops before I get there, and each hop will slow you down. Your ISP can't control that. So when I hit Comcast at 125 Mbps by the time my data comes back from Singapore it may get slowed down to 50 Mbps due to traffic jams on the Internet.

It's also going to depend on how heavy the server you're trying to connect to is being hit. If it's overwhelmed with traffic it's going to be slow to respond.

Test your speed to your ISP. It's the only reliable metric.

Just an FYI, but always take speed test results with a grain of salt.

I have Charter/Spectrum internet, nominally 60 MB download/5 MB upload. Testing that connection on speedtest.net yields 66/5.5 MB. Testing the same connection on the Google speed test shows as much as 312 MB upload speed and AT&T shows as much as 113 MB upload speed, but in both cases the upload speed slows dramatically near the end of the speed test. There's no way Spectrum allows me such high upload speeds, so sometimes the reported speed depends on how the test software is written.

70/6. I guess it's like weather reports - shop for the best one

Thanks

When I'm not a plane, I work from a home office and deal with large files on a daily basis. I've gone back and forth with Brighthouse (now Spectrum) for years on this. I'm supposed to get 50mbps download speeds, and every independent test I conduct shows 20-25mbps. One day it was so bad I was getting page time-out's on both Google and Edge, so I did a chat session with Spectrum, and magically their speed test showed 55mbps download speeds.

They couldn't, and still can't give me a reasonable explanation (shocker) why 4 or 5 independent tests come up with the same values, yet their's is always "within spec".

Depends FROM WHERE you run the speedtest...

If you run the test on a phone or tablet or any other wireless device, it will measure the speed to the wireless device, not to the WIRED home network.

I just ran the Comcast test on my wired laptop and got 71 and 6. I ran Speedtest.net on the same computer and got 74 and 6. So NO DIFFERENCE (you get small differences each time you run tests).

I ran Speedtest.net on my phone and got 39 and 6, because the phone is connected WIRELESSLY to my home network.

By the way, before upgrading to more expensive service you need to UNPLUG the cable modem and wait 30 seconds, then plug it back in and wait 3 minutes. Many people didn't realize that Comcast increased speeds in packages, and if you had reset your modem you may have found a higher speed than 20/5 before you upgraded...

My speed is slower since they made it faster.

Hell, I am about 37/4 and feel like I am actually in the 21st century. My office is over 200 down and not sure the up but we don't upload anything interesting anyway.

1. Just because it is two different tabs tells you nothing about the destination server. The Comcast server is 99% more likely to closer to you than the other - and once you leave Comcast's network doesn't mean much.
2. I would also avoid putting too much faith in wireless speed tests - there are simply too many variables to properly control for. Something as simple as moving a few feet can move you from the 5Ghz to the 2Ghz and your speed will drop.
