Yes, I have the same issue. Started around Thursday too.
Running the speed test gives a result of 0.2 Mbps for downloads.
Tried the usual troubleshooting steps like resetting the router and testing with a wired connection but nothing changed.
Before attempting the troubleshooting steps, TPG recommends that you:
1. Check our Service Status at https://www.tpg.com.au/servicestatus
2. "Power cycle" your ADSL modem. This means turning your modem off and waiting for one minute before turning it back on again. This allows your modem to reestablish connection to our server.
If you are still unable to connect to the Internet, you can proceed with the troubleshooting steps indicated on this link: https://www.tpg.com.au/support/problems_connect_internet.php
We understand that you have tried troubleshooting. We can see that your issue has been escalated to our Engineering Team.
We have raised this to our wholesale partner Telstra as we have identified a fault on the line affecting the service and they have committed to send a technician to fix the issue.
