Telstra Smart Modem Cellular is very slow

I purchased a Telstra Smart Modem with the hope that when my ADSL failed or slows which it often does that I'd get some usable speed when switching to Cellular. Sadly in recent months it seems no faster than my ADSL landline - around 0.4Mbit/sec. At the same time when I check the speed of my iPhone on the same Cellular network -it gets around 20Mbit/sec. While I realise that the smart modem is capped to 6Mbit/sec, I really don't think that 0.4 Mbit/sec is a realistic speed against the advertised data from Telstra, particularly when I know that the cellular network is putting out much higher. Why is the cellular on the smart modem so slow - has the speed been c controlled even further.

Was this helpful?

  • Yes it was, thank you

Re: Telstra Smart Modem Cellular is very slow

Your 4G backup might be throttled to 256Kbps because if the signal light is either green or orange should get close to 6 Mbps down and 1 Mbps up.. If backup is used for extended period of time it gets throttled to 256 Kbps. To have throttling removed ring support and request a web form be submitted to have throttling removed.

Without attempting to accuse you of wrongdoing, the bolded part of your message suggests the reason. Do you ever disconnect the ADSL cable on purpose? I.e. when ADSL slows down, you disconnect it and hope that backup provides better speed? If so, that's not what it was designed for and you are probably throttled down as @cf4 suggested. The backup is designed to take over your connection automatically when and only when the ADSL or NBN connection fails. Not when you wish so.
