Comcast Speed Tests

speedtest.comcast.net does have the advantage of sitting inside the Comcast network, however, removing some variables from the test. That can be very useful when you're trying to isolate the source of a problem. The external tests may be a better gauge of the real user experience, though.

I don't put much stock in those speed test sites. They generally give "OK" results, but just try and download something. That's how you can really tell, and that's when Comcast's "throttles" kick in. I'm supposed to be getting 4Mb/sec speeds, but lately, downloading ANYthing feels like I'm back on dial-up.

I might be wrong but I believe you should at least be getting 6Mb d/l unless it hasn't happened in your area for some reason...where are you located?

What are you seeing with the speed tests?

On the Comcast site I see 20 down and 9 up.

Everywhere else I see about 12 down and 6 up.

And the up & down is still determined by the "server". Doesn't matter if Comcast allows 50 mpbs & the server providing the download is only allowing 256 kbps or so. Some files I get 750+ KBps & some others, only 100 KBps depending where & what time of day & how many people is trying to get something from the same place even if I only have a 6 mbps setup.

.........lots skipped..........

My own followup but decided to check the speed for file xfer.

Recalled G. Lucas had a ftp site with a few files for download; just got a 10.3 meg file; ncftp says 9.9 MB @ 1.96 MB/s...

Looks like lucasarts still has high connects to the internet since the 1.96 MB/s xlates to about 15+ Mbps (1.96 x 8); will need to check again as either I'm getting the new upgraded 12 mbps plus booster or booster works for a 10 meg file; could be the time of day as well, but I'm a happy camper since the capability is there if the remote server allows it.

ATT Uverse is making a big push in my area. I wasn't too impressed at their prices for internet so I thought I would test my speeds on Comcast. Here are the results..........

Down, 2.34 Up Down, 1.37 Up Down, 2.3 Up Down, 2.38 Up

I'd be happy if I had that kind of up speed (I have roadrunner standard service):

5806 Kbps down, 478 Kbps up.

Modem is clocked at 6144 Kbps down, 512 Kbps up. Makes it hard to share files with this low an up speed.

Here (Silicon Valley) at 7:45pm Friday night:

19.247 Mbps down, 3.132 Mbps up

I "lost" my Sprint Broadband service on July 31, 2008, due to FCC reallocation of the frequencies, so sought any replacement other than DSL. I found this: with a Google search; $19.95/month, free Motorola SB5101 DOCSYS 2.0 modem, and over $200 in rebates. The $19.95/month is for the first 6 months. The rebates were paid very quickly.

Checking just now, the offer is again repeated at $19.99/month, offer expires November 30, 2008.

that's no lie. i had blast 16 megabits down, until i used it with giganews for about a month. those gems at comcast are throttling my speeds to about 1/4 of what they were at giganews. how can one monolithic company suck so much? with the money they are pulling in, why are they so freaking stingy with bandwidth.

caran had written this in response to

: I got here using a searcher, i been having problems with my wifi for several days and its getting worst every day. I think everytime i do a [url= test[/url] my speed decreases. may it be possible? i tried opening some ports as a friend told me, can somebody help me?

You have some _very dangerous_ friends.

With friends like that - who needs enemies?

Do not open ports unless you have a specific need to do so.
