Ok, understand, you're using the wifi app to run a speedtest within the modem. Do you happen to have any ethernet connected devices that can be used to run a speedtest, and that will support 930/940 Mb/s?
I'd call tech support and ask the CSR to run a signal check to see what turns up. My personal opinion is that the upstream levels are too low, but, its a question of whether or not they are acceptable at the neighbourhood node.
Are you running any other Rogers services such as Cable TV or Home Phone, and if so, would you happen to know if there is an amplifier connected to the cable system where the cable enters the home?
Are you in a house, or apartment/condo/highrise building?
Edit: Ok, so a tech is arriving today. Hopefully he or she will be able to see what the problem is. Nope, I'm not a technician, just a Forum volunteer, so I and the other volunteers don't have access to any of Rogers systems.
Ok, understand. Normally the Cable Modem Termination System (CMTS) would issue a command to the modem to increase the transmit signal level out of the modem if the received signal level at the neighbourhood node was too low, which I suspect it is. So, the fact that the modem is still running at a low output power level is very odd. That's not a normal occurrence. Have you already swapped modems by any chance?
Thats hard to say. I'd suspect the modem is at fault, but, swapping with another modem will prove or disprove that theory. The tech support comments on "SNR and tx power" runs in both directions, firstly from the neighbourhood node to the modem, using the downstream DOCSIS 3.1 OFDM channel, and secondly, from the modem to the neighbourhood node using the four DOCSIS 3.0 upstream channels.
If the downstream OFDM channel wasn't running correctly, that would or could cause slow data rates. As I indicated above, the user interface doesn't present all of the data required to assess the OFDM channel, so, that requires tech support or a field tech to look at the parameters to see if there is a problem with the OFDM channel.
If the upstream channels are not arriving at the neighbourhood node with adequate signal levels or signal to noise ratios, then that could affect the downstream rates as the upstream responses might not be received and would have to be retransmitted by the modem. That retransmission could result in slower downstream rates.
So, the field tech will have to asses what the problem is and come up with the correct solution.
I recently upgrade my 150 unlimited Ignite internet to Rogers Ignite Gigabit, and receive a big disappointment. My Wi-Fi download speed now is :
1- Asus laptop - 34mbps
2- Samsung 7s edge - 64 mbps
3- Cubot power - 54 mbps
4- ipad 5th generation - 150 mbps
5- PC with AORUS Z2370 gaming 5 Motherboard - 180 mbps (Wi-Fi), 530 mbps (Ethernet).
So only the direct line Ethernet is somewhat approaching hi- speed while all WIFI devices got very low speed.
Rogers service came twice to look at the problem and said that was normal ! I said this was the worst sale ever for a Rogers service.
I need to mention that in Jan. 2018, I had also bought a Rogers Ignite Gigabit UNLTD plan and used it for over a year with much better results (Wifi consistently over 500 mbps on all devices above), before going back to 150 Ignite Internet for a few months.
So my question is : What has happened to Rogers Wifi download speed ?
