To restart your Vodacom fibre router, simply unplug the power cord from the router and leave it unplugged for 30 seconds to a minute. Then, plug it back in, and the router will power up again. This will effectively restart the router and resolve any minor connection issues. 

Detailed Steps:

1. Unplug the power cord: Find the power cord connected to your Vodacom fibre router and unplug it from the wall and the router itself.
2. Wait: Allow the router to sit unplugged for at least 30 seconds to a minute.
3. Plug it back in: Reconnect the power cord, plugging it back into the wall and the router.
4. Wait for it to restart: The router will power up again, and you may see lights on the front of the router as it boots up. 

Alternative Method (if the power button is not present):

• Some older routers might not have a power button. In these cases, you can simply unplug the power cord and wait, then plug it back in. This is the same as pressing the power button. 

Additional Tips:

• If the issue persists, try a different Ethernet cable to rule out a damaged cable.
• If you still can't connect, contact Vodacom customer support.
• You can also try a factory reset, which will restore the router to its default settings, but you will need to reconfigure it afterwards
