I am wondering if this modem by Technicolor TC4400-AMV2 works with the ignite 1gb internet service?
As the provided modem from rogers I only see. To get 240-350mb when hardwired directly to modem
?? Rogers provided you with a TC4400 modem?
Are you able to log into the modem to check the modem signal levels? If so, you should be able to copy them and paste them into a post.
That modem is normally used for Third Party Internet Access (TPIA) providers. So, I wonder if the modem is provisioned correctly to run at 1 Gb/s for the download rate. You would have to ask tech support what data rate the modem is provisioned for.
Other food for thought, if your using a windows based pc, have a look at the following page regarding the Receive Window Auto-Tuning level:
This situation of slow download rates has come up very recently with another customer and was resolved by setting the Receive Window Auto-Tuning level to normal if I remember it correctly.
Run the following command at a command prompt to see what your Auto-Tuning level is currently set to:
netsh interface tcp show global
Take note of the current setting:
Then, using a command prompt with administrator rights, run the following if you want to set the value to experimental. The values for this setting are shown on that microsoft page:
netsh interface tcp set global autotuninglevel=experimental
or set it to normal:
netsh interface tcp set global autotuninglevel=normal
Reboot the computer if you had to change the setting.
After you've had a look at the autotuning level, call tech support to:
1. Check the signal levels. Ask the customer service rep to specifically check the OFDM signal levels and QAM levels. Rogers uses QAM levels of 4096 on the Hitron CODA-4582, and probably the same on the two XB6 modems used for the Ignite TV service. Within the OFDM channel data, there should be about 10 to 12 data points, representing small frequency bands within the OFDM channel. Each band will have its own signal level, signal to noise ratio and QAM level. The question is, are they all acceptable, and, what are the QAM levels that this modem is showing. I'm assuming here that the smaller OFDM band data is accessible, as it is for the CODA-4582. Maybe not?? While there might be an overall average of the signal level, signal to noise ratio and QAM level, that data should be broken down in to smaller frequency bands and hopefully the tech can find it. The QAM level stands for Quadrature Amplitude Modulation, essentially how the data is encoded for transmission. The higher the QAM level, running up to 4096, the faster the data rate, the lower the QAM level, 64 QAM, the lower the data rate. So, its a direct indication of how fast the modem will run, and its a direct indication of acceptable signal levels and signal to noise ratios.
2. Next, ask the tech to confirm what data rate the modem is provisioned for, gigabit service, or a lower data rate.
Ok, slightly confused at this point. How is your modem configured? I'm assuming that with the Ignite modem, you have:
local pedestal --> outside demarcation point --> inside splitter (?) --> Ignite modem --> pc
That should work.
What you can't do is the following:
local pedestal --> outside demarcation point --> splitter (?) --> Ignite modem --> pc
You can only have the assigned modem running, which in this case is the ignite modem. In this configuration, if the TC4400 works at all, I'd be surprised. It really shouldn't work.
Now, it might be possible to call tech support and swap the modem mac addresses and serial numbers on the account so that you can run the TC4400 rather than the Ignite modem, but, then the question is, does Rogers have the correct TC4400 configuration file available when the TC4400 boots up? Is that what you have been doing, swapping the modems on the account by calling tech support? If so, and the TC4400 actually runs, but runs at a slower speed, I think the problem is the configuration file for the modem, which would be supplied by Rogers when the 4400 boots up. That might be resolved by a call to tech support to determine if the 4400 is set to use the OFDM channel and what the modem is provisioned for. Tech support might be able to change the provisioned data rates, if that item is available in the modem settings for the 4400.
Do you have one of the XB6 modems which is used for the Ignite TV (IPTV)? If so, you should be able to run 900+ Mb/s. Same for the white CODA-4582 modem. But, you would have to know that the windows autotuning level is correct and know whether or not the modem signal levels are ok, specifically that the OFDM channel signal levels are ok with QAM levels above 1024.
That is what it shows when I run the cmd netsh interface tcp show global

as for my ignite modem it is
@Krooked, ok, so, the Receive Window Auto-Tuning Level is set for "normal", which is the usual setting. You could try setting that to experimental and then reboot the pc just to see if it makes any difference.
What is your test pc, in terms of its processor and memory?
Did you have a chance to speak with tech support regarding the signal levels and if so, what did that turn up, if anything?
