UL speed issues

NorthGraves
I Plan to Stick Around

Curious if anybody else experiences the following symptoms:

3552 modem, .22 firmware, Gigabit service

 

After CM reboot, the upstream signals are ~37.250 in each of 3 channels, and the upload speed is 50 Mb.

Then within 1-2 days, the signals change gradually closer to 33-34, and the upload speed drops to 14-16 Mb.

 

After I reboot the modem, the signal is back to 37+ in each of the three upstream channels, and the UL speed is back to 50 Mb.

Can you log into the modem, navigate to the STATUS .... DOCSIS WAN page, copy the downstream and upstream tables and paste them into a post.  The copy and paste process will paste in the text contents of the tables.  The upstream levels of 33-34 dBmV are slightly low.  It would be interesting to see both tables to see if there is a signal issue on the go.

Re: UL speed issues

Hey guys, I have the Gigabit plan, but my upload speed always maxes out at 30mb/s. I know some areas are running 500mb/s max download using Cisco with 20 channels. My area is CASA and I have 32 down stream channels, shouldn't I be getting full Gigabit speeds? (1GB/s down, 50mb/s up)? I got the Gigabit service for the 50mb/s upload, so this is very important for me. Wirelesss I do between 500-650mb/s download, upload 30. Wired 700-800mb/s down, upload 30. Anyone here on Gigabit using CASA and being limited to 30mb/s? 

 

here are my signal levels:

What firmware version are you on?

 

The choice of test server also makes a difference.  Try the speedtest.net Toronto Beanfield server and speedtest.fibrenoire.ca server.



Re: UL speed issues

network release .21
I have tried the Rogers server, Telus, beanfeild. All the exact same results on upload. Download will vary, but upload always hard stop at 30-31.

Ok, stay on .21 for now if the upload is important.  Just to note I was testing .21 on my CGNM-3552 earlier today and the highest that I saw was 47 Mb/s up.  

 

I wonder if you're in an area that is maxed out at 30 Mb/s for some reason?  

 

Wired is direct to the modem via short commercial Cat 5e/6 cable?  



Re: UL speed issues

Wired was direct to the modem via the yellow cable that came with the Modem. I'm on the phone with Rogers now, they say my package is caped at 30Mb/s upload, but didn't say why. I'm still on hold while they figure this out. I was never told I was gonna be on a 30Mb/s package when I signed up for this. I was told the Gigabit plan, which on the Rogers website shows 1GB/s down, 50Mb/s up. I specifically chose this plan for the upload speed.

I came across another post just like your situation earlier today.   Turns out the area wasn't ready for full gig service.

Re: UL speed issues

I just got off the phone with Rogers. I called tech support first, they confirmed I'm on a 30mb/s capped plan. He then transferred me to accounting to change my plan to the 50mb/s upload plan. The lady said she made the change to 50mb/s upload, however I just did a few speed tests, and my speeds are all over the place. Downloads 200-300mb/s, upload 22-28mb/s. I dunno what to do now, I'm afraid they may have provisioned my modem on an even slower plan. All I want is what I pay for, Gigabit with 50mb/s upload. I realize Gigabit will most likely top out at 850-900mb/s, but I should be getting full upload speeds.

I've seen plan changes take immediate effect.  Wait for a few minutes to see if if settles out.  If in doubt call tech support again to confirm the plan provisioning in the modem.

one more thing, when I login to myRogers, it shows my internet plan as 250u. My Home Phone show the correct plan, and cable says extended basic (I'm on Popular)

*EDIT* The Modem did reboot when she said she made the changes, so something was changed.

@gp-se Sorry to say they changed your plan to the 250U plan, you will need to call back in to switch it back to the gigabit plan. 

Re: UL speed issues

I sent a PM to community helps, I'm not waiting on hold for half an hour again.

Re: UL speed issues

Hello @gp-se,

Call back in and use the 'call back' option (where Rogers calls you when an agent becomes available).  I have been using this recently with great success - I can do other things and work with Rogers when they call (instead of sitting on hold).

 

Alternatively - @RogersHelps on twitter is also a great option - I am getting 3-5 hour turn-around, and contact them when I am running around doing errands / at work.

Re: UL speed issues

Community Helps confirmed the changes are correct, 1 Gb/s down, 50Mb/s up. I tested this morning at 7:30am, I was able to upload at 45mb/s. I am happy 🙂

Re: UL speed issues

Gigabit Service slow upload speeds

 

Hi there, I had Gigabit service installed last week and I have yet to get an upload speed of more than 15mb/s.  In fact, most times it's around 3-6mb/s meanwhile the advertised speed is 50mb/s.  I know I am never going to get what is advertised but at least give me 50% of what they are saying I should get.  One of the primary reasons for me to get the gigabit service was to get the upload speed.  I never get more than 750 mb/s down at anytime of day (I've tried at various times during the day/night).

 

Attached is a screenshot from the Rogers Speed check.  What's odd is that the Rogers speed check reports 750mb/s down and 15 mb/s up however the ookla speed test on their site states 650 mb/s down and 7 mb/s.

 

My router is in bridge mode.  I have done these tests right from a machine connected to the modem eliminating my LAN.

 

Please lmk if anyone can think of something. I've even tried different DNS servers.speedtest.png

 

 

Re: UL speed issues

This is the current speed I am getting with my 1 GB service at 8:40 PM Oct 24/16:
