@hemrajghaley the speed test result is indeed slow for the plan and type of technology used to deliver NBN.
Have you tried switching off the wireless and connecting a PC directly to the modem for testing purposes? Sometimes the devices connected to the network and the gadgets or structure around us affect the wireless connection speed.
Switching to a different type of NBN Technology is not possible @hemrajghaley. There can only be one type of NBN technology that can be rolled out in a certain area.
Nevertheless, I can have one of our Technical team to contact and assist you to check what's causing the low download speed.
Could you please send your best contact time & number via private message so we can organise a call back to be made for you?
We'll wait for your response.
We have requested for a Sr Technician to call you on Sunday.
Be reminded though that we are not sending a technician out since we're not detecting any issues with the network. Instead, someone will call you to assist you over the phone to check why you're getting a slow connection.
In addition, I suggest that you try testing the speed of your connection with computer/laptop connected directly to the modem to determine if the problem you're having is WIFI-related only. If the connection speed is good with a device connected using ethernet cord, then, I suggest you check this link on how to improve your WIFI speed.
