Is my ISP throttling me?

post #1 of 11
Thread Starter 
I have wireless internet and I recently had my antenna rotated towards a closer tower so I have better quality service (before it was very laggy and slow). Now my ping is stable and everything, but I think they are throttling my download speed. I pay for 3 mb down 384 kb up internet service, but whenever I download something (from any site) it downloads at 250 kb/sec max (as if I had a 2 mb down connection). If I start 2 downloads at once, then my connection is maxed (same with torrents) but I'm also doing a lot of updating through programs and games that only make 1 connection to the server so it downloads at 250 kb/sec.

I called them about it and they said that they don't cap or throttle bandwidth and asked me what I get on a speed test, so I went to speedtest.net and got this:



I told him what I got and said "since the speed test shows 3mb down for you, there's nothing we can do" and got all defensive and stuff.

But the whole 2mb down 'cap' is really bothering me, I'm paying for 3mb down but I'm not really getting it. I went to some other speed test sites and a lot of them are showing I have a 2mb down connection:







Do you think there is anything they will do about this? Or do you think they will just tell me the same thing again?

Did you do all of these speeds tests at the same time? Because if you were able to get 3mb/s down from speedtest.net then your ISP is providing you with the service they agreed to. It could also be that these other speed test sites don't have as good or as close of servers as speedtest.net.

Since you are in Michigan speedtest.net's chicago server will undoubtedly show better results than the 2nd test you tried which had its server located in Florida.

When you run a speedtest like that, you should ALWAYS choose the geographically closest server. If you choose a server in LA for example, you will hardly reach your max speeds (there's many hops in between).

Testing from Michigan to Florida for instance, is not a valid test....

From the looks of it, no, they're not capping or anything.

You probly need to tweak your windows settings and 250 of 300 is pretty good.

No, I did all of those tests at different times when nothing else was using my connection. And I understand that servers farther away can give different results, but the 2 mb cap seems to show on about every other speed test site besides speedtest.net (regardless of distance)

I remember reading somewhere that some ISP's would only allow a customer to use a fraction of their advertised speed, but would allow them full bandwidth only for speed test sites. Think this is something similar? (speedtest.net is the speed test they offer on their site)

250 kb/sec of out a possible 384kb/sec is alright I guess, I just find this really annoying and wanted a few other opinions on the matter

Do you get better results when you test off peak times, say 3am on a weekday, compared to 6-8pm on a Thursday night? If so, that could also explain your variances.

That right thier says your not capped if you was capped you wouldnt get over 250 no matter what you need to maybe go to dslreports and run the tweaker to tweak your windows settings.

If you decide to change, for the love of God don't go with Time Warner. They charge you extra if you go above the monthly max download. Ridiculous that they are trying to treat the internet like phones. :\\

Speaking of tweaking your network stack. One parameter that could offer you instant results is tweaking your MTU (Maximum Transmission Unit), by default it is set to 1500 bytes, you can try reducing it to say 600 bytes, to reduce the number of retransmissions in your link.

It just depends on the times you do the test and the amount of load the servers have and many other things. Have a look at my ISP.


My results change all the time depending on when I do the test aswell. I have noticed.

Edit: One sec.
