Troubleshooting Internet Issue

Which router do you have? The white cylinder? The TelusSmartDevice network is specifically set up for 2.4GHz smart devices to connect to. The regular wifi often will switch between 2.4 and 5GHz which would cause most smart devices to disconnect.

If you're on fibre, Line 1 and Line 2 (phone lines), will always say disconnected. That is normal.

Have your tried the connection with a hard wired computer? There are so many things that can interfere with wifi in an average home. Once you test that, if the wired speed is not close to 300mbps, then call Telus for assistance.

For the white battery box with the red light, call Telus for that one. It likely just means the battery died or there's an issue. That should not affect your connection or speed.
