How to tell actual charter speeds?

Did you power cycle your modem? Personanly I can't trust speedtest.net results anymore and haven't in nearly 2 years.

try this

So how am i supposed to be able to tell what my actual speed is? With the "power boost" theyve got going I cant get a real value from the java tests and the flash just gave me a return of 20676Kbps down and 796Kbps up? And from Speedtest.net ? Im on the formerly 5Mb tier.

//edit: Just did the charter based speed test and came out @ 7.2 / 1.

This is what I get using the Java tests.

Make sure you reboot your cable modem and then download a BIG file (~500MB). After a while (I don't know, 20 or 30 seconds???), PowerBoost will end and you'll drop back to your configured maximum speed. As long as the file is big enough, the initial PowerBoost skew won't affect the average and you should get a reasonable idea of whether or not you are getting your rated speed.

Most browsers tell you the final download speed when the transfer finishes. Do the math. If you achieved 600KB/second throughput, multiply that by 8 and you get 4,800,000 bits/second. or 4.8Mbps. That's a misleading number because TCP/IP has overhead but the browser is only counting the bytes that make up the file. It might be more accurate to multiply it by 9 or even 10 to arrive at the raw throughput. The raw throughput (i.e. including overhead) is what your modem/CMTS considers when throttling your connection.

If this approach doesn't yield the speeds you think you should get, before getting irate with customer service, try a similar sized file from several different sites. The site's geographical proximity makes a big difference in terms of packet loss (which can stall the download until the TCP/IP stack recovers) and latency.

If you have Windows XP, consider increasing the RWIN with the tweak tools available here. I don't know if the same concern holds true for Vista, Win7, OSX or Linux. Check out the many forums here for further information.

I think there is something up with the new jersey one. I used that one and got 947/1063.

I used the new york one right afterwords and got something more accurate, 9914/1049.

It's too bad you can't retest with a different server. Plus, it'd be nice if they had some sort of of ping test there.

reply to BF69
uh...
The applet on the uberbandwidth.com says Ookla, which basically is speedtest.net

It's the same application just different server.

Same here in the Greenville/Spartanburg SC area. It has been 4 weeks now with a 20/1 speed. At first I thought it was a tease put out by Charter (I was on 5/512 for years) But now I must give it to them, it works well!

speedtests are lame anyway hope thats not your only benchmark...
