Hi

1.  We have a big house

2. We have Trustpower fibre internet, unlimited

3. We have one user of Netflix who uses it on their laptop, via wifi.

4. We have 2 other users which use it for smartphones mostly, and occasional laptop and printer, all wifi.

4. Quite often when Netflix user is streaming this crashes the wifi connection and we need to reset the router, even when no one else using the wifi.

So we have been advised by Trustpower that it the Netflix which is causing the problem.  When we use the other laptop we will use it hard wired into router from now on.  We have been told that the Netflix needs to be hard wired into router also to stop the signal being 'stretched' and breaking (crashing).  We would like to connect a wire from the router up into the roofspace and down into the room where the Netflix user watches it, about 10 metres of cable needed perhaps?

Can this be a DIY job?  If so any advice would be appreciated.  Sorry I don't know the brand of the router offhand but it is whatever Trustpower supplies. Ta Jo
