Why is my office internet slow?
ISP plans, Wi‑Fi coverage, bufferbloat, and LAN bottlenecks — how to diagnose sluggish business connectivity.

Define slow
Separate download speed, upload speed (critical for Teams and cloud backup), latency, and Wi‑Fi dropouts. Run wired tests at the modem first — if Ethernet is fast but Wi‑Fi is not, the problem is local wireless, not the ISP.
Plan and contention
Under-sized NBN or business fibre plans, oversubscribed cheap plans, and too many cloud backups at once all hurt. Check upload Mbps when video calls stutter while downloads look fine.
Wi‑Fi and switching
Concrete walls, metal racking, and one router for a whole warehouse cause dead zones. Old 100 Mbps switches or daisy-chained hubs bottleneck desktops. Upgrade access points before blaming Telstra or Aussie Broadband.
Bufferbloat and QoS
Large downloads can inflate latency for everyone else. Run a speed test that measures loaded latency, then enable sensible QoS on your firewall if bufferbloat scores are poor.
