How To Troubleshoot Speed Issues

[NeddieMarsh]

I have an iMac and since the middle of next year it disconnects from my Telstra wifi and will not reconnect. The iMac gives varying and different reasons each time: Wifi too crowded; manual IP address etc. Telstra sent a new modem and the problem persists. Yet, when I took it took work for about a week to test it, while it dropped off from time to time, it reconnected without any difficulty. It works fine on the Ethernet.

Hi NeddieMarsh,

Thanks for contacting us. It does sound like it maybe an issue with your iMac's wireless adaptor. How old is the device?

Do you have any issues with any other device on the network?

Hi NeddieMarsh,

Can you confirm the model of your modem? If it is one of our Telstra Smart Modems, you may find that disabling the Band-steering function will help as some older devices don't work well with it. 

If you do have a Telstra Smart Modem, you can disable this by accessing the modem page and going to the Wi-Fi menu at the top. Remove the tick next to 'Enable Band-steering' and then save the changes.
