Ignite Internet Gigabit - Slow Speeds

[SpencerW]

I had a Rogers tech at my house 2 days ago and they did a speed test and only got 150mbps on what ever software they use

@SpencerW did the tech indicate that he or she was going to raise a ticket with a senior tech or the maintenance crew?  What were his or her plans to address the situation?  Those notes should be on file, so, if you call tech support you should be able to find out what the next step is.  If you do that, you should ask if another ticket has been raised and if so, is that ticket still open, or has it been closed with providing an resolution to the problem?  If the ticket is still open, where is that ticket sitting in the que, and if its been closed, then another ticket should be raised.  In either case, obtain the ticket number so that you can call tech support and refer to that ticket number, looking for an update. 

Are you measuring those low data rates via ethernet, or wifi?  Any speedtest to confirm that the modem is delivering the intended internet plan data rates should be conducted via ethernet.

My speeds are slow I’m on gigabit getting 600mbps I think my docsis signals aren’t good plz check and fix

Are my signals good

[Datalink]

@AzaanKamran the top DOCSIS 3.0 channels (1 to 32) are fine.  I wouldn't expect any issues with those, but, the modem isn't using the DOCSIS 3.0 downstream channels at the moment. 

The DOCSIS 3.1 OFDM channel is the download channel in use.  There isn't enough data presented in the user interface to know of that channel is operating within spec.  That would require a call to tech support to determine. 

The DOCSIS 3.0 upstream channels are all low, lower than normal for this modem which usually runs in the 30 to 32 dBmV range.  That might not be a problem however, depending on the signal levels when they arrive at the neighbourhood node.  They might still be well within spec.  

Call tech support and ask the Customer Service Rep to run a signal check on the modem.  Ask if the Downstream OFDM channel is operating within specification and ask if the upstream signal levels are within spec at the neighbourhood node.  

I'm assuming that your in a house, which is connected to a neighbourhood node.  If you live in an apartment/condo/highrise, then your building could have its own Multiple Dwelling Unit, or several of them, to service the apartments in the building.  That might explain the low upstream levels.  If that is the case, then the question of the upstream levels becomes, "are they acceptable when they arrive at the MDU?"

One last question at this point, how are you measuring the data rate, via ethernet or wifi.  If its via wifi, then you need to run a speedtest via ethernet with a pc/laptop which will run download rates in the order of 930/940 Mb/s. 

If you're testing to this point has been with wifi, don't call tech support until you've had a chance to run a test via ethernet.

I’m just getting 800mbps download

[Datalink]

Yes, but, is that via ethernet or via wifi?

Can you have a look at the following post and if you're running a Windows pc or laptop, check the current TCP Receive Window setting.  You could set that to "Experimental", reboot the pc or laptop and then rerun the speedtest to see if that makes a difference in the results.
