Gigabit fibre hardware: Cat6a, 2.5GbE and real throughput
Understand wired ports, Cat6a and 2.5GbE before troubleshooting Canadian gigabit or multi-gigabit fibre.
Measure this device, then see your guide
Download, upload, ping and jitter are measured against AI Speed’s test route. The test may use up to 153 MB on a fast connection.

Follow the entire path
A gigabit or multi-gigabit subscription does not mean every device can receive the full rate. Inspect the optical terminal or modem port, router WAN port, router LAN port, switch, cable and device adapter. A single 1GbE link limits that part of the path to roughly gigabit link speed, with real application throughput lower due to overhead.
When 2.5GbE matters
If the subscribed plan exceeds 1 Gbps and you want one wired device to use more than a gigabit, both ends of its path need compatible multi-gigabit ports. A 2.5GbE router WAN port alone is insufficient if the LAN port, switch or computer still negotiates at 1GbE. Check negotiated link speed in the device settings before interpreting a browser test.
Cat6a versus existing cables
Cat6a can be useful for structured cabling and longer multi-gigabit runs, but buying it alone will not increase speed when ports remain the limit. A good existing Cat5e or Cat6 run can support some higher speeds at suitable lengths and conditions. Before recabling a home, confirm the port standards, cable condition, run length and whether the household use case needs a single-device multi-gigabit result.
Test the right workload
Compare a direct wired test with a Wi-Fi test and note the device specifications. A fast plan may mainly benefit several people sharing the link, even when one device cannot hit the full tier. Repeat measurements, avoid assuming every remote server can serve data at line rate and look at upload, ping and jitter for the tasks that matter. Verify fibre availability and plan terms at the exact address.
