Does the CODA-4582 support Jumbo Frames?
I cannot find any means to set the MTU on the LAN side of the CODA-4582. Anyone know if this is supported?
This response will contain guesswork.
Why do you want jumbo frames? I imagine that they cannot transit even the Rogers part of the internet.
If you want them just for your LAN, and if the Hitron's switch does not support them, just stick your own switch (one that supports jumbo frames) on the LAN, make all your connections to it, and then connect one port of the switch to the Hitron.
I would hope (but have no idea) if Path MTU Discovery would let it all just work. It used to be that many (other people's) routers dropped ICMP and made PMTUD fail on the internet. Maybe even the Hitron fails to send the requisite ICMPs. An easy experiment would provide the answer.
@GolfGeek I don't think I've seen any mention of setting the MTU on an Intel Puma 6 or 7 modem, and that's across several ISPs. So, if its actually in the firmware, its not presented to the users. If that's the case, then it might be possible to code the option without too much effort on Hitron's part. If its not in the firmware, then Intel would probably have to develop the code for this and if that's the case I suspect that there are a good many higher priority items that need to be taken care of first.
But, there is no harm in asking for the option. Is this specifically for Jumbo Frames on the LAN?
The setting to enable it IS visible... I can plug a USB stick in and the interface recognizes it... no idea how to get access to it on the network though... is this still being worked on?
?? The modem will only recognize a USB2 stick. Running a USB3 stick requires code changes by Intel. I believe its on the list of things to do.
The one thing that I haven't explored is the USB Enable/Disable in the BASIC SETTINGS .... GATEWAY FUNCTION TAB. I don't know if there is another menu that comes up when the USB is Enabled.
After the USB2 stick is enabled, its a matter of mapping the drive. There is some trick to it that I don't remember. There are a couple of posts in the forum that show that, just have to find them.
One primary difference is that Rogers Hitron modems support two separate IP addresses in Bridge mode, so, an additional IP passthrough isn't required as the Rogers modems and network already support the simultaneous use of two IP addresses.
If the idea is to run an IP passthrough for the purposes of a separate IP address, while the modem is in Gateway mode, my personal advice would be to buy two routers and run the modem in Bridge mode , or buy a reasonable router that provides the required DMZ performance mode and run the modem in Bridge mode. It all depends on the requirement for a separate (secondary) IP address.
To clarify, were you actually getting two public IP addresses (e.g. 18.104.22.168 and 22.214.171.124)? Or was one of them an internal address (e.g. 192.168.1.1)?
@0x they were two public addresses as the modem was/is running in Bridge mode and each router is connected directly to the modem. That configuration wasn't working before Christmas which is unusual as its been very reliable up to that point. On my list of things to do is run a test as soon as I can to see if @RogersDave has had an opportunity to address this. I'm not sure at this point if its an issue with my CMTS or an issue with the 4582 modem running firmware version 126.96.36.199T3
With any of the modems running in Bridge mode, you should be able to connect two devices to the modem and end up with two public IPV4 addresses, same for IPV6 addresses.
This modem has certainly been a headache and time waster for me since switching from 250u service to 1GB service this week.
I have returned twice as per Rogers tech and customer service, same issue persists.
Regardless of hard wired ethernet or WI-FI, I am maxing out speedtest.net tests at 200Mbps on a GOOD test, generally anywhere from 140-200Mbps.
Rogers seems clueless on the issue, even though its all over here, I dont know why they either deny the issue, or act as though its the first time they have heard of it?
Either way, my 250u service I Was hitting 350Mbps consistantly upon tests, and that was even on Wi-Fi let alone Ethernet wired.
All I know is I am overpaying for what I am receiving and certainly losing patience with the issue, and unsure of where to go from here.
I have an open ticket with Rogers, and supposed to here back within 48 hrs, however I dont assume anything will come of that either at this point.
Is anyone else having problem in this modem with the Local DHCP? When I reset the modem it works fine for the 1st day or so but then any computers/devices trying to connect either via LAN or WiFi can't auto-obtain an IP address from it. If I setup manual IP addresses the devices will work but if they are set to auto they will just be left "Identifying" or come back with "Connection Test Failed, Could not connect to router".
I have been searching high and low on the internet but this thread seems to be the only place for resources on this modem.
Also, does anyone know of any solutions or if mine might be faulty.

I also tried changing the release time from 1 week to other options but that didn't help.
