You may have been here because just like us, you have received a new wireless router from SingTel and transferring files locally on FTP is extremely slow or completely impossible. We made numerous phone calls to SingTel, but they refused to acknowledge this issue. The technician who came down understood our problem but he was not able to convince SingTel to provide any remedy. Fortunately, AzTech technician was able to provide a workaround.
Go to ‘http://192.168.1.254’ using your browser (The IP address is different if you have changed it)
Click ‘Advanced Mode’ on the top right corner
Click ‘Advanced Setup’ on the left panel
Click ‘Quality of Service’ on the left panel
Uncheck the box that says ‘Enable QoS’
Now save and reboot your device, and your FTP should work properly
We hope this guide helped you save several hours in troubleshooting. Cheers!
