Cat5e supports up to 1 Gbps internet connection.
Hello! Your new townhouse has CAT5E wiring, and you're currently using Shaw's internet 600. Since your cable speed is only up to 1G, switching to Telus fiber 1G might be a good idea once your contract ends. Yes, upgrading to CAT6 could provide better performance for future needs.
It's not essential because you'll be near the top of maximum speed. If you get 1 gigabit per second and your cables can handle up to that, you'll never exceed the speed your cable supports. The internet speed is typically at its peak and not exceeding it, plus stable 1 gigabit connections are uncommon, so you usually experience a few hundred megabits of variation.
Cat5e supports gigabit rates and manages traffic smoothly at gigabit speeds up to 100 meters. It can also accommodate 2.5Gb and 5Gb at distances of 100 meters and 30-70 meters respectively. Unlike Wi-Fi, the cable doesn’t lock onto a fixed speed; it adapts or won’t negotiate to specific rates like 10/100/1000/2500/5000. Occasionally, external factors might affect speed negotiation, but in most scenarios—about 98% of the time—that won’t occur. A damaged wire near a strong EMI source can cause issues, but with proper installation and termination, you’ll fully benefit from your gigabit upgrade. *Assuming the cable remains intact and there’s no interference.*
Thanks for the feedback. Another factor I'm evaluating is whether CAT5E could reach its full bandwidth on internet and local traffic, potentially exceeding 1G. I recognize this scenario is uncommon.
One cable can handle data in both directions simultaneously. If your device doesn’t support full duplex, it will transmit and receive at the same time, but the maximum speed is determined by the interface rather than the cable. With a switch and router, your setup looks like this: Router---| PC----Switch PC-------| PC----| Local traffic is managed by the switch, giving each PC gigabit on its connection. However, if all three devices try to access the internet or router activity at once, the switch’s gigabit port connected to the router becomes the limiting factor.
However, with gigabit equipment you're limited to 1G, even using advanced cabling like cat6+. To achieve higher multi-gigabit speeds, you'll need networking gear that supports multiple gigabits. If your switch is capped at gigabit, you won't need to replace the cabling.
Cat5e and Cat6 both support 1gbps, but Cat6 handles interference better. In a typical home setting, Cat5e should work fine without major issues. Cat6 is ideal for bundling many cables or working near high-voltage power lines. It can carry 10gbps over about 30 meters, though if you need more than that, Cat6a is a better choice. If you require sustained speeds above 1gbps for LAN and WAN, costs rise significantly. Prices have dropped recently, but a basic 4-port switch starts around $130. Each device costs about $100 for two SFP ports plus a network card. If you need more than four devices, the Unifi XG 16-port switch at $600 is likely the most affordable option.
Based on what I understand, it's likely unnecessary even with a 1G internet connection.
It depends on your priorities. If you're handling large data transfers constantly—like 1gbps downloads from the web while managing high-speed NAS SSDs at over 5gbps—then the investment might be justified. I'm used to needing strong connections, with multiple VMs and media servers running around. Right now it feels like a power user, but prices are dropping, so I'm waiting a bit. In the worst case, backups and transfers might slow things down a bit, but if it saves you time—say $50 an hour—it could pay off within a year.
