Yet Another Hello With A Question :)

Recommended Posts

Hello all.

I'm happy to be new member of testmy.net. I do have a question however :)

I've been using insight bb for few years now. Few months ago I upgraded from broadband 10 to broadband 20, but...

but the tests on tesmy.net give me speeds well below 10Mbs - constantly.

Highest I got within few weeks of testing, was ~8Mbps, where most of the results are around 4 to 6 Mbps.

The latest run is shown below:

:::.. TestMy.net Test Results ..:::

Download Connection is:: 5218 Kbps about 5.22 Mbps (tested with 4 MB)

Download Speed is:: 637 kB/s

Upload Connection is:: 1351 Kbps about 1.4 Mbps (tested with 1.5 MB)

Upload Speed is:: 165 kB/s

Tested From:: https://testmy.net (Dallas, TX USA)

Test Time:: 2011-01-10 13:48:24 GMT -7

Validation:: https://testmy.net/db/UNOXHJA07&q2=XK0IRZ746&dual=yes

User Agent:: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.13) Gecko/20101203 Firefox/3.6.13 [!]

After calling (finally :) ) Insight I will have a technician coming within few days to check on the issue.

Testing done during phone call on http://insightbb.com/speedtest do show my speeds are 20 Mbps.

I am living in Louisville, KY. The provider is of course InsightBroadband.

My computer is running on Windows 7 and I'm using Motorola Surfboard SB5100 Cable modem and Linksys WRT54GL router.

The question I have is quite obvious :) Why the speeds are so low?

Appreciate any help.

Most likely their speed test is hosted internally. So I wouldn't go from what their test says... read this ... pay attention to paragraph 2. -- that however lets you know that your line is running as it should up to the point of the ISP. Most likely there is a slow link in the route from Insight to TestMy.net. You're only as fast as the weakest link between you and the server. ISPs that use congested routes sometimes try to cover up that fact by hosting their speed test internally... pushing users to it and then say, "See, your line is working as it should..." --- then they blame the other guy.

Post a traceroute if you can... Although, problems like that don't always show up in a traceroute.

To run a traceroute...

  • Windows Start > Run > type CMD [enter] > from the command prompt type tracert google.com and/or tracert testmy.net
  • Linux / Mac Under Applications/Utilities open 'Terminal' > type traceroute google.com and/or traceroute testmy.net

Paste those results here.

I see other Insight users that get over 20Mbps here all the time (one example). Do you have issues with your speed when downloading files?

Thanks Cable for quick response.

I actually found the info about internal testing by isp providers after my first post.

No problem...

Hop 4 in the route TestMy.net looks congested to me. There is no reason why a bounce that close to you should have a 200+ ms response time. That is a router that Insight directly controls. (by the way... ignore hop 12 on my end, it's supposed to time out)

The trace to Google however looks good, but that's because traffic to Google is being routed through a different router.

... Looks to me like Insight is pushing too much through that router.

You said:

"... Looks to me like Insight is pushing too much through that router."

What does that mean?

I mean that they are routing too much traffic through that router. It's possible that they haven't even noticed... it's also possible that they are working on a solution right now. I would contact them and show them that traceroute.

SO... after the technician came and checked the modem, he said that I am getting too strong signal, which is the cause of my low speeds problems. I was preoccupied with other things at the moment and completely forgot to ask what exact signal power was... (facepalm)

I found here

http://homepage.ntlworld.com/robin.d.h.walker/cmtips/signal.html#goodlevs

that downstream power levels should be between -15 to + 15 dBmV

Following the

http://homepage.ntlworld.com/robin.d.h.walker/cmtips/signal.html#goodlevs

How to discover your cable modem signal levels

Im getting :

Software Version: SB5100-2.3.3.0-SCM00-NOSH

Hardware Version: 3

MIB Version: II

GUI Version: 1.0

VxWorks Version: 5.4

Downstream Value

Frequency 597000000 Hz Locked

Signal to Noise Ratio 38 dB

Power Level 13 dBmV so mine is within -15 to + 15 ... (confused)

The Downstream Power Level reading is a snapshot taken at the time this page was requested. Please Reload/Refresh this Page for a new reading

Upstream Value

Channel ID 1

Frequency 29000000 Hz Ranged

Power Level 39 dBmV

I see that my downstream power signal is within the range. Don't know how its affected by being almost at the +max though.

Does those values make any sense?

EDIT: I am trying to run DocsDiag but having problems with java atm.

I also have insightbb. I took two test and here are the results. I'm on the 10/1 plan! Just out of curiosity have you power cycled your modem? Also a bad splitter can cause this problem.

Hey Conuck, thanks for replying.

I have no splitters in the set-up. Cable goes straight out of the wall to the modem. From there it goes to the router. From there by wire to my desktop and by wireless to my gf computer.

I did power cycle the modem, router, all computers.... several times :) No difference
