I plan to stick around

Just upgraded to this modem today from a 250U plan to Gigabit. Bufferbloat is killing me. I can't sustained more than about 350Mbit/s downstream before it starts spiking ping times to over 300ms for other users.

 

Does using an aftermarket router help or should I return this modem for the previous model?

@Webslinger,

Your signal issues are as a result of this:

I don't think returning this thing is a good idea - Rogers is trying hard to get the 3552s replaced so they can deploy DOCSIS 3.1 (which the 4582 supports). 

 

 

Also, in terms of getting another router and bridging this thing - that's usually a very good idea (though I don't know if it would help here - @Datalink?), though I think you have to be very careful (and spend big $$$$$) to find a router that will actually do NAT at gigabit speeds. 

Re: Rogers Hitron CODA-4582 Hardware

@HKPolice1 which modem do you currently have, the new CODA-4582 (big white modem), or, a CGN3ACSMR or CGNM-3552 as seen by the product sticker at the back of the modem?  

 

If its the CODA-4582 I would start by doing a restart.  Pull the power plug, wait for 30 seconds and plug it back in to force a restart.  If that doesn't resolve the issue, run a factory reset, either from the user interface, ADMIN .... DEVICE RESET .... Factory Reset, or, depress the recessed reset button for 30 seconds and release it.  That is located just above the ethernet ports at the back of the modem.  

 

As for a router for gigabit speeds, its time for customers to consider something like a Pfsense or Opensense router and a stand alone wifi router which does nothing but wifi duties.  Expensive yes, but, it depends on what people want for protection from their router.  Providing that protection on a router running at speeds in the high hundreds of Mb/s will take something better than the vast majority of typcial consumer routers.  On the other hand, if someone is looking for a consumer router, you need to look for something with a 1.4 or 1.7 Mhz processor.  The faster the better.  Asus routers with AiProtection running will drop the IPV6 data rates due to the scanning that takes place for IPV6 traffic.  Netgear routers filter IPV6 ICMP which is required for IPV6 to operate.  So, the choice whittles down fairly quickly.

I've run PC-based routers for 15 years now, and... ironically, I would be MORE nervous about a PC-based router for gigabit than something more specialized.

 

 

My worry would be primarily to do with performance limitations on the interfaces/bus. Doing gigabit NAT implies having two maxed out interfaces...

 

Funny thing is, before I got my current box, the previous box I was running was a Cel. 600. 100BT on the motherboard for Rogers; PCI GbE card (IIRC, or maybe it was 100) for the internal network. Seemed to perform fine... but it was basically maxing out at 35 megabits or whatever the speed of my old plan was. When I replaced it, suddenly I started to see SpeedBoost... 

Re: Rogers Hitron CODA-4582 Hardware

Ive read through a bunch of these threads and I'm not sure i saw a definitive answer for 4582 bridge mode and dlink dir-890L ??

 

I can not for the life of me get the 4582 to hand out an ip to the 890.  I even tried flashing the 890 to ddwrt and it still wouldnt grab an ip.

 

Currently not using the 890 but would like to get bridge mode to work.

 

4582 still running .13 firmware - tech support wouldnt push anything...

 

Any help would be awesome!!

Given the "P" ticket related to that incident is closed, I'm a bit concerned that Rogers may not move to fix the signal noise issue in my area soon. People, in general, are mostly concerned with download. If they're averaging 2-5 Mbps, they may not even bother calling in about the problem.

I'm having the same problem - it seems to have started recently. I can't get past 450mbps before I get buffer bloat as well.

Last week, I was getting 850 - 925mbit/s with the modem.

This week, I'm maxing out at 450mbps.

I can't get past 400 - 450 mbits the last couple of days.

Are you guys using an external router or the one built into the modem? I wonder if I should bother even trying another router.

Re: Rogers Hitron CODA-4582 Hardware

Well I can say that in my short experience with the 4582 when i am connected to it without a router i can get 900+ down and 50-53 up.

 

I finally got it to go into bridge mode with my dlink dir-890l using the latest beta dd-wrt firmware and my speed test was cut almost in half.  

 

Put the 4582 back in gateway mode and it is back to full speed.

DD-WRT does not support hardware NAT only software based, so it will be unable to achieve gigabit speeeds on the WAN.  This is a common complaint with Open and DD WRT.

Well, I have a D-LINK DIR-895L and refuse to install DD-WRT on my router.  The firmware is still too new and based on the very little response I am seeing on their forums, it's not good and causing big issues so I will stick to my factory firmware which works until something more concrete is usable.

 

With that being said, I still have a very expensive paperweight which used to work on the previous 3552 modem in bridged mode but since moving to this 4582 - just like others have mentioned with D-LINK routers that it's not handing out IP's bridge mode.

Using pfSense - so external router. Last week, I was hitting 925mbit/s ... but since then my speeds have collapsed.

Re: Rogers Hitron CODA-4582 Hardware

I recently upgraded from the 250U plan /w the CGN3-ACSMR modem to Gigabit /w CODA-4582.

 

Previously, I was able to sustain roughly ~300Mbit downstream speed while having relatively stable ping times of ~50ms to the default rogers gateway. Now the ping times are spiking to over 300ms with  even when I throttle the downloads to around 350Mbit. If I don't throttle my download speed, ping packets will time out constantly.

 

What is the point of a Gigabit connection if 1 person downloading causes everyone else to lag? My brother games everyday and he never complained about lag when I was using the old modem. Now whenever I download anything, he complains about lag and how it's ruining his game.

 

Is it possible to swap back to the old modem until Docsis 3.1 is deployed?

 

PS: Already have the latest firmware installed 2.0.10.19 and using a 3rd party router: Netgear R7000 /w hardware acceleration on, can hit speedtests results of around 850Mb/s but upstream is limited to around 36Mb/s.

The ACSMR isn't supported for gigabit plans; you'd have to get a 3552 which is the 32-channel Puma 6-based model.

 

 

I have no other substantive suggestions to offer, sadly... though I admit that based on the facts you've given, I would be tempted to consider downgrading back to the 250 plan unless you got a crazy deal like the $99 deal...

Does the 3552 modem also suffer from buffer bloat? I'm guessing it's more of a CMTS setting issue though?
