Testing your Brightspeed connection
Brightspeed serves around 20 states, mostly in smaller cities and rural areas, where it is replacing old copper lines with fibre. Its fibre plans are symmetrical and go up to 8 Gig in select areas. Where fibre has not arrived, Brightspeed still sells DSL with much lower speeds.
This test detects your provider automatically and measures download, upload, ping, jitter and latency under load against the nearest server on Cloudflare's network. Enter your plan speed under the result to see the percentage you really get.
Brightspeed speeds by plan
| Plan | Download | Upload |
|---|---|---|
| Fiber 300 or 500 Mbps | 300 to 500 Mbps | same as download |
| Fiber 1 Gig | 940 Mbps | 940 Mbps |
| Fiber 2 Gig | 2,000 Mbps | 2,000 Mbps |
| Fiber 5 Gig and 8 Gig (select areas) | 5,000 to 8,000 Mbps | same as download |
| DSL | up to about 20 Mbps in many areas | a few Mbps |
Tiers as advertised by Brightspeed in 2026; the entry fibre tier and the multi-gig plans depend on the area. Checked on 31 October 2026; tiers change and vary by address, so confirm on the Brightspeed website.
What result should you expect?
On Fiber 1 Gig, a wired test should show about 900 to 940 Mbps in both directions. On DSL, a result close to the speed on your broadband label is normal, even if it is low.

Common reasons for slow Brightspeed speeds
- Wi-Fi only tests: test once over Ethernet next to the router. See fibre slow on Wi-Fi.
- DSL line length: see speed up slow DSL and ask whether fibre has reached your street.
- Frequent drop-outs: see internet keeps dropping.
- Red light on the fibre box: read red LOS light.
Before contacting Brightspeed support
- Restart the modem and wait for a steady internet light.
- Run three wired tests at different hours.
- Check Brightspeed's outage information before calling.
- If speeds stay below your plan, check for traffic throttling, then contact support with your saved results.

Frequently asked questions
Is Brightspeed fiber symmetrical?
Yes. Brightspeed Fiber plans advertise equal upload and download speeds.
Why is my Brightspeed internet so slow?
If you are on DSL, speed depends on the length of your copper line and is often low. On fibre, test over a cable first: the Wi-Fi is usually the limit.
Is Brightspeed the same as CenturyLink?
Brightspeed took over part of CenturyLink's former local network in 2022, which is why some customers moved from CenturyLink to Brightspeed.
