How do I test my Fibrus speed?

Use the speed test tool on this page to measure your Fibrus download speed, upload speed, and ping latency. For accurate results, connect directly to the Fibrus router using an ethernet cable. WiFi speeds will be lower due to wireless overhead. Fibrus provides full fibre so speeds should be consistent at all times. The test takes approximately 30 seconds to complete.

How does Fibrus compare to BT in Northern Ireland?

Fibrus offers faster speeds at lower prices than BT in Northern Ireland. Fibrus 1 Gbps costs approximately £40/month while BT Full Fibre 900 costs over £50/month. Fibrus also offers 2 Gbps which BT does not match. Both are genuine full fibre (FTTP). Fibrus has extensive rural coverage in Northern Ireland where BT may only offer slower connections.
