Question 1

Is Cat5 cable still good enough for my home internet?

Accepted Answer

Cat5 works fine for internet speeds up to 100 Mbps, but if you have gigabit internet (1000 Mbps or faster), you'll get better performance with Cat5e or Cat6. Most homes today benefit from Cat5e as the minimum standard since it's cheap and handles modern speeds without issues.

Question 2

What's the actual difference between Cat5, Cat5e, and Cat6?

Accepted Answer

Cat5e has better shielding and twists in the wire pairs to reduce interference, letting it handle gigabit speeds reliably. Cat6 goes further with even tighter specifications and supports higher speeds over longer distances, but the difference only matters if you're running cables over 50 meters or in noisy electrical environments.

Question 3

Does cable length affect internet speed?

Accepted Answer

Speed doesn't drop with distance, but signal quality does degrade beyond 100 meters with Cat5 or Cat5e. For anything under 50 meters in a home setup, length makes almost no practical difference—buy what you need without worrying about overkill.

Question 4

Should I buy shielded (STP) or unshielded (UTP) cables?

Accepted Answer

Unshielded (UTP) is fine for most homes and offices—shielded cables are mainly needed in industrial areas with heavy electrical interference or next to power lines. Unless you're in a factory or dealing with specific interference problems, UTP saves money and works just as well.

Question 5

Are expensive branded cables better than cheap ones?

Accepted Answer

Quality matters more than brand name—check that cables are certified (look for Cat5e or Cat6 markings) and have good reviews rather than paying for a logo. A solid mid-range cable from any reputable seller will outlast and outperform a cheap knockoff.
