Re: FEEDBACK - Rogers Rocket Wi-Fi Modem Firmware Trial

its 8-10mbps both ways.

 

Here are the signal levels now.

Re: FEEDBACK - Rogers Rocket Wi-Fi Modem Firmware Trial

Ok, those aren't too bad.  The downstream is a little higher that I'd like to see, but that shouldn't cause any issues at this point.  The downstream OFDM is a complete mystery as the OFDM data isn't presented as it should be.  So, this requires @RogersAndy , @RogersTony or @RogersMoin to check the OFDM Mibs to see if the sub-channel data is ok.  

 

The QAM downstream Channel IDs are a little odd with the low channel ID's being assigned to the high frequency channels.  That won't have any effect on the downstream performance, but, its a little odd.  

 

Your modem is running a DOCSIS 3.1 OFDM channel for the downstream data and four DOCSIS 3.0 QAM channels for the upstream data.  So, their completely different methodologies of transmitting data.  Its strange that you're seeing low data rates in both directions.  Was this the same situation prior to 7.1.1.37 loading this morning?

Re: FEEDBACK - Rogers Rocket Wi-Fi Modem Firmware Trial

yea i think the data values were pretty much the same before the firmware push.

 

Was getting gigabit speeds with no problems.

 

Keep getting intermittent disconnects although 1- 2 times a day on average. Spoke to rogers tech who had opened a ticket, acknowledging neighborhood modems were going offline at the same time. Ticket was opened. Nothing was done as usual.

Re: FEEDBACK - Rogers Rocket Wi-Fi Modem Firmware Trial

Ok, if you were getting gigabit speeds prior to loading .37

 

1.  Reboot or power cycle the modem.  Check the speeds after the reboot and if that has had no effect:

2.  Factory reset the modem.  Yup, its a pain to reload the various parameters, no doubt about it if you run the modem in Gateway mode.  Usually after an update, a reboot is required to get the modem back up to its normal performance, and, if that doesn't work, don't hesitate to run a factory reset.   From what I've seen dating back to the original Hitron CGN3 modem, its always been this way with Hitron modems, even though there's a reboot built into the update cycle.  

 

Now, food for thought, you can have decent looking signal levels and still get disconnects if there's a problem with the external cable or its connectors.  If you run a ping test to the CMTS, you will see if there is any packet loss between the modem and CMTS which is indicative of a cable and/or connector issue.  

 

To do this, run trace to anywhere, google for example:

 

tracert -4 www.google.com

 

With the modem in Gateway mode, or with the modem in Bridge mode followed by a router, the second IP address i the trace is the CMTS.  Ping the CMTS.  Note this should be done for both IPV4 and IPV6, but running a ping test using IPV4 is a start.  

 

Ping -n 3600 xxx.xxx.xxx.xxx      where xxx.xxx.xxx.xxx is the second IP address in the trace. 

 

That will run for an hour and then terminate.  The question is, are you seeing any packet loss for that period of time.  

 

You can run longer tests by simply increasing the number of pings from 3600 to your preferred number, or, run a continuous test until you terminate the test.  

 

ping -t xxx.xxx.xxx.xxx                  which will run until you stop it by using Ctrl c  (Control c).   

 

If you let that run overnight for example or during the entire day, it might show some interesting numbers.

Good speed here but bufferbloat sucks.

Re: FEEDBACK - Rogers Rocket Wi-Fi Modem Firmware Trial

just did a factory reset.

 

speeds were gigabit for around 10 - 20 min or so.

 

now back to 10 mbps.

 

this is really frustrating. anyway i can default back to the production firmware or this modem is gone now?

Re: FEEDBACK - Rogers Rocket Wi-Fi Modem Firmware Trial

Very frustrating to say the least!!  You would have to send a message to @CommunityHelps to have your modem removed from the firmware test list, and ask if you can revert to the production firmware which I believe it .35

 

I'd be interested in seeing the signal levels just after a reboot when the speeds are running gig speeds, and then see the same signal levels when your speeds drop down to 10 Mb/s.  

 

Out of curiosity, are you using one or more Nextboxes for tv and a Home Phone service as well?  Just wondering about the presence of a splitter in the system, not that its going to make a huge difference.  Your previous signal levels looked ok, so, its pretty perplexing to see such a huge drop.  

 

Running a MoCA system by any chance?

 

Using all ethernet ports or just one or two?

Re: FEEDBACK - Rogers Rocket Wi-Fi Modem Firmware Trial

no just have internet that's about it.

 

rebooted modem through interface. speeds are normal for now. here are the signal levels.  Modem is in bridge mode.

 

guess will message community helps to downgrade!

Re: FEEDBACK - Rogers Rocket Wi-Fi Modem Firmware Trial

Ok, their still not too bad.  There is a difference however.  Have a look at the OFDM Downstream Overview.  Your previous post shows the OFDM channel running with receiver 1 where you had slower speeds.  This time around, you're running on Receiver 0 and your speeds, at least so far, are what they should be.  That might be something worth keeping an eye on.  I'd like to see what happens if and when the speeds drop.  Does the receiver flip back to #1?

 

What are you running for a router?

 

Just checked my 4582.  Its running on Receiver 0 this time around.  Looking back on my records, it flips every once in a while, so, there doesn't appear to be any pattern that I can see.

 

How far apart are the modem and router?  They should be several feet apart to ensure that there's no wifi EMI influence on the modem from the router's wifi transmissions. 

 

Fwiw, after I saw you're posts earlier on, I ran a couple of speedtests using the Speedtest.net Rogers Ottawa server.  I ended up with 940-943 Mb/s down / 32.8 Mb/s up.  That's a normal set of results for our location in Ottawa.

Re: FEEDBACK - Rogers Rocket Wi-Fi Modem Firmware Trial

oh wow you could spot out a difference in the values but i could not. speeds are back to 10 mbps just within a few minutes of rebooting.

 

modem and router are quite far apart. I dont think its a router issue but will try to test speed directly wired to the modem as well. router is asus rt ac68u

 

only difference i see when modem has normal speeds is the plc power value

 

1.79 normal speeds

2.00 below normal speed
