FAQ
Is Cat6 future-proof?
For typical home lengths, modern copper categories are usually ample. Follow installer advice for your run length.
Is Cat5e enough for gigabit?
For typical home lengths, often yes. Follow installer advice for your run length and goals.
Should I run cable inside walls?
Neater and protected, but hire qualified installers for permanent work.
Can I use flat cable under carpets temporarily?
You can, but avoid damage and trip hazards. Permanent trunking is safer long term.
Do I need a switch if I run one cable?
If you need more ports at the far end, add a small switch there.
What about fibre to the desk?
Some installs use fibre for noise immunity. Discuss with pros if you have interference-heavy environments.
