Slow internet speeds

I Plan to Stick Around

Recently I've been getting 40-55mbps download speeds when I'm supposed to get 100mbps (usually when I do speed tests I get 150mpbs). My upload speeds are what I'm supposed to be getting (10mbps).

You say when  you are doing speed tests, you are getting 100+??

How else are you showing/knowing that you are only getting 40-55 otherwise?  Just curious.

If its thats what you are maxing say on a Torrent, or download from somewhere.. that is quite possible that its a restriction on the throughput on the software itself.. or the SENDING side is maxing out speed wise that it can upload to you.

I did a Rogers speed test a couple of times before I posted this topic. Since yesterday I've noticed a slowdown of speed whenever I tired to connect to a website. During the tests I wasn't running any internet heavy applications (ie downloading torrents or streaming media).

Re: Slow internet speeds

My internet at home acting really weird last night. It is really slow. I tried the speedtest. It only got to 2M download...

Did some research on the forums and tried couple things there including reboot my modem multi times. Here is the information I got from my modem. Some data seems a bit off. I guess I will call to book an appointment soon. Any idea?

And those speedtests are fine? or slowed down?

A slow loading page initially could just be DNS issue.

Signal posting would be appreciated to help check some things.

Most likely... your issues ARE signal related.

Those signals are WAAAAY to low.

You would want to book a tech to come out.. and have them check everything.. street, outside the house, etc.. and replace connectors, etc as needed.. and hopefully fix the issue (bar it being say a STREET signal issue, etc)

I just did the speed test again and the results were: Ping- 12ms, Download- 16.69mbps, Upload- 1.25mpbs, and Jitter- 2ms. These speeds are significantly lower than what im supposed to getting (100mbps download and 10mbps upload). Here's the info you were asking for,

Re: Slow internet speeds

You need a tech to inspect / replace the external cables and connectors.  Your signal levels are either at or beyond the DOCSIS limits.  The downstream limits are +15 dBmV down to -15 dBmV with a signal to noise ratio of 36 to 40 dB. The upstream is normally within a 36 to 40 dBmV range with an upper limit at 51 dBmV for three or four channel upstream operation.  So, your downstream levels are below the bottom downstream limit and the upstream levels are at the upper limit.  That is normally a classic sign of a cable and / or connector failure with the external cable.  Just as a quick check, ensure that the RG-6 cable is connected securely to the modem connector.  Hand tight will do. 

 

Call tech support, ask the CSR to run a signal check on the modem and indicate that you are seeing slow data rates.  The signal issues should cause large bit errors which the CSR should see without any problems.  The follow on conversation should see a tech visit to your home in the next day or two.

 

When the tech has completed his or her work, can you repost the signal levels, just to see how they turned out and post the results of a speedcheck from either http://speedcheck.rogers.com/en.html or www.speedtest.net using the Toronto Telus server.

Ok thanks for the info, I'll be sure to contact tech support today and I'll report back here when they fix my problems.

Re: Slow internet speeds

The tech came in today and here are the updated signal levels. I also ran the speed test again and the results were (On 5G wifi) Ping- 12, Download- 45.41mbps and Upload- 2.81mbps. The speeds are still lower then what I should be getting, but the only time the speeds are what they're supposed to be is when you plug in a computer directly to the modem.

Re: Slow internet speeds

While the signal levels are slightly higher than they were before... i am suprised that they still left with those signal levels.. they are way too low.


Part of your last post, brings something up.

You said that when you plug in wired, that you are getting the proper speeds??

That shows, that the modem IS providing the proper speeds generally to your house.

Speed tests, always should be done wired where possible.

Wireless.. in the end, are too many variables which can effect it.
The wireless to start in the rogers (and just about ANY carriers gateways) is pretty poor.  Its fairly simple and strugles to provide the FULL max speeds possible on the plan, even in the BEST scenarios.
But even assuming that it CAN do it... there are many other factors which can/will effect the speed as well.
Not all wireless cards in the receiving end are built equal either... and can effect maximum speed.
Interfearance also is a big factor.   Other wireless signals nearby (expecially prelivent in an apartment/townhouse).  Other interfearance on the same bands (cordless phones, bluetooth, microwaves).   Even just the house itself.. copper pipe, iron ibeams, metal studs.. can all damper wireless performance... limiting its maximum speed.

Re: Slow internet speeds

Yep, agree with Gdkitty.  Signal levels are improved but not good at all.  Are you in a house, apartment, condo, highrise, etc, etc?  Just wondering.  As Gdkitty indicated, there are a number of factors that are involved in good wifi performance, some easy to solve, some not so easy to solve.  You can start by having a look at the wifi environment that you're in.  If you load inSSIDer (freebie), from the link below, that will show you how many other 5 Ghz networks are running nearby, and whether there are better channels to be using.  That version does not show 802.11ac networks which also occupy 5 Ghz networks.  There is an updated version out which is a pay version that does show those networks even if your laptop doesn't support 802.11ac.  The program reads the transmit header data and displays the 802.11ac networks along with the 802.11n networks, providing a complete picture of the 5 Ghz space.  For $20 US, definitely worth it if you use 5 Ghz networks.  What you might be able to do is change your operating channel to one that is at or above Channel 149, as those channels have a higher allowable power output.  That will help with the received power levels at both ends and should help with the throughput speeds, even if the gain is only marginal.  Also check the channel bandwidth.  Thats a judgment call, but what you can do is experiment with the 20Mhz and 40 Mhz settings for the 5 Ghz network.  Run 20 Mhz if you operate at a distance from the modem, as it will restrict the total power envelope to a 20 Mhz wide range, and if you are normally closer to the modem, run 40 Mhz wide, the tradeoff being reduced power levels across a 40 mhz wide range for greater throughput due to a 40 Mhz wide range.

If nothing is wrong with your modem, diagnostics, cable feed, signal strength, etc., etc. then the issue IS rogers speed test. It's not accurate, point blank. I went thru this same issue when I got the 100 Ignite. ONLY on rogers speed test was the weirdness going on (oscillating between 40-50 mbs on the download but upload speed was correct) whereas on all other speed tests, the dl speed was waaay above 100u averaging between 121-23 mbs on the low end to 149-59 mbs on the high end. I spoke to several tech reps and they did all the diagnostic tests they could think of and said nothing was wrong.

 

Do the following tests.

 

 

speedtest.net - do multiple tests with multiple servers and get an avg

 

SpeedOf.Me -do multiple tests, get an avg

 

TestMy.net - do multiple tests, get an avg

 

speedtest.reliableservers.com - this involves real-time downloading a test file in MB/s. I suggest the 1 gb file. For example 100u is 100,000 bits/8bits per byte = 12,500 bytes or 12.5 MB/sec. This is the minimum download speed for a 100u line. If you see the download MB/s is exceeding this number then you know you are getting at or over 100mbs, what you paid for... 

 

Then average ALL your test results from above. If it is equal to or greater than 100mbs or 12.5 mb/s download then there's nothing wrong. You are within spec for the 100u plan.

 

Try this and re-post ur results.

K, def. something is not right. Try this last test. Goto http://speedtest.reliableservers.com/ and click on the 1 gb file download test. Once clicked you will see a link that says "Show all downloads". Click that and you will see real-time download in MB/s. Tell me what you see. Roughly what range are the download figures?? ie. 10 mb/s to 12.5 mb/s, etc. If the figures are consistently below 12.5 mb/s then you need a tech service call. Something is causing the slow internet speed whether there's interference on the line, flapping issues, signal strength, modem, faulty connection switch in outside box, etc. The other figures you produced above def. indicates something is wack. This last test would prove it 100%. Be sure to use direct connect via ethernet (wired).

Re: Slow internet speeds

Ok, the only result that I trust of that bunch is the wired test with the Telus server.  Is the Speedtest Telus server located in Toronto or Montreal?  Not to disagree with @pac_west227 but the Rogers speedtest results and Speedtest Telus Server results that I see are usually very very close.  On a wired test I usually see 327/328 Mb/s down, 22 Mb/s up from both.  Thats on a 250/20 service.  Running 802.11ac on a gaming laptop, I see the same results via wifi.  The problem with using other test servers is that you have to know what they are testing, single stream to a particular server, or multiple data streams from several servers to max the connection rates.  Comparing them is like comparing apples and oranges.  You can do it, but you have to know what each speedtest is designed to test. 

 

Your wireless 5G and wired test results are a little interesting.  I'm wondering why the wifi speeds are higher than the wired speeds?  While it is possible, its really unusual to see that.  Are you running 802.11n or 802.11ac for the wifi, and is the wired test run on the same device?

 

I would say, given the signal levels that you currently have, that you should call into tech support and have them run another signal check on the modem to see what turns up.  They might indicate to you that yep, the test results are within spec, but that doesn't explain the slow test results that you see.  Typically on a 100/10 service, you should see somewhere in the neighbourhood of 130 to 140 Mb/s peak download rates with speedboost, 10 to 11 Mb/s upload rates. 

 

Are you in a house, apartment, condo, highrise, etc, etc?

Sorry for the late reply I was busy this afternoon @Datalink I ran the tests on the same device and for the wifi I was running on a 802.11 ac wifi adapter. Also I live in a house. @pac_west227 I downloaded the file and its lowest speed during the download was 2.0mbps and peeked at 7.7mbps. Its average was around 5.5mbps on wifi.

Re: Slow internet speeds

pac_west227

Yup, those results are terrible. I just did the 1 gb file just now. Range was from low of 11.8 mb/s to high of 15.4 mb/s. I would say 95% of the time it was in the upper range so definitely greater than 100mbs on a streaming download. 15.4 mb/s = 123.20 mbs. You definitely need a tech service call. Have you swapped your modem for another - just to eliminate that variable?? If u have and nothing is wrong with your puter than u need to book an appt asap.

 

Good luck.
