Thanks for your quick reply and let me know that my firmware is the latest version. I did check the firmware history yesterday. I saw the latest version is 220.127.116.11 there, but didn't know it's still in trail.
BTW, my home internet has intermittent disconnection problem for long time. For that reason, I upgraded my Ignite package from 500b to Gigabit(to get a better modem). Thereafter, I also called tech support. A technician came and checked box outside and replaced the connector on wall in room. Since then, the network worked well for about a week, before the disconnection occurs again. It happens at least once a day, 3-4 times often. Sometime it connected back automatically within few minutes. Sometime it refuses to work even I reboot modem several times. Everything goes randomly. Now I have got used to it, because no choice. That's why I thought maybe the modem needs to be upgraded to 18.104.22.168, or is there a chance that I can get a latest modem? My neighbor has the same Ignite package, but with a newer modem.
@squ6688 can you log into the modem, navigate to the STATUS .... DOCSIS WAN tab and copy the downstream and upstream signal data table and post those in a new message?
To do that, park your curser in front of the Downstream Overview line, hold the shift key down, and scroll down to the very bottom of the OFDM/OFDMA overview section. With that entire area selected, release the shift key, right click on that area .... Copy. In a new message, right click .... Paste. That should paste in the entire table, as it appears in the modem's user interface.
The starting point here is to look at the signal levels to see if they show any unusual signal losses which would explain the issue.
Be aware that in numerous cases, a single contractor tech visit may not solve the issue. If it hasn't, and that is how it appears, don't hesitate to call tech support and complain about the problems. Don't let tech support upsell you to the Ignite system. Before anyone moves from the Hitron modems to the XB6 or XB7 modems which are used for the Ignite TV system, they should ensure that their internet service operates as it should. I wouldn't expect a modem change to necessarily resolve a poor signal issue, although moving from an environment with internet service, numerous Nextboxes and maybe a Home Phone modem to a single XB6 or XB7 can make a large positive change in the signal levels as seen in the modem. That can have a positive impact on the reliability of the service, disregarding the impending wifi problems when switching to the XB6 or XB7. Intermittent cable signal issues are another matter altogether. That should be fixed before anyone switches to the XB6 or XB7.
You should be aware that switching to a newer modem doesn't mean that its any better. The Hitron CODA-4582 modem uses an Intel Puma 7 chipset, as does the Arris built XB6. Essentially the same chipset but with telephone capability in the case of the Arris XB6. There is also a Technicolor XB6 which would be the preferred version of the XB6. That is built with a Broadcom BCM-3390 chipset, which has no resemblance to the Intel Puma 7 chipet.
The XB7 also comes in two versions from what I recall, a Technicolor XB7 using the Broadcom BCM-3390 chipset, and an Arris version. I don't remember at the moment if Arris finally woke up and decided to use the Broadcom BCM-3390 chipset, or if they stuck with the Intel Puma 7 chipset. I'll have to look that up again. My preferred version would be the Technicolor XB7.
For the XB7, there’s a Technicolor version and a CommScope version. The CommScope version uses a MaxLinear chip. MaxLinear recently purchased Intel’s “connected home” and their Puma intellectual property but there’s no indication (yet) that they’ll make any devices with a Puma 7 chip. The MaxLinear chip in the CommScope XB7 pre-dates the Intel acquisition stuff. I agree…my personal preference would also be a Technicolor XB7 (if someone is using it in gateway mode with WiFi enabled and if someone wants/needs WiFi 6) or a Technicolor XB6.
By the way, Rogers is currently reserving XB7 devices for people with Gigabit plans. I’m sure there are some agents and techs that will make exceptions but anyone with less than Gigabit will likely get the XB6.
