Is It Your Ottawa Internet, Your Internal Network, or Just One Device?
-
Run an Internet Speed Test
Start with a wired speed test using Speedtest.net. Compare results with your ISP’s advertised plan. If the numbers are far off, your issue may be with your internet provider.
-
Check Scope of the Problem
Is the slowness affecting all devices or just one? Is it consistent or only during peak hours? Narrowing this down saves time.
Diagnosing Common Bandwidth Bottlenecks in Your Ottawa SMB
Bottleneck #1: A Device or App Hogging Bandwidth
-
How to Check: Task Manager (Windows), Activity Monitor (Mac), or router device lists.
Common Culprits: Large downloads, cloud syncing, streaming, P2P, or malware.
Fix: Pause/limit large transfers, schedule updates after hours, scan for malware.
Bottleneck #2: Too Many Devices for Your Current Plan or Router
-
How to Check: Count active devices. Compare to your plan capacity and router specs.
Fix: Upgrade to a business-grade router and a more robust internet plan.
Bottleneck #3: Wi-Fi Issues — Interference, Weak Signal, or Outdated Gear
-
How to Check: Compare wired vs. wireless speeds. Test signal strength around the office.
Fix: Reposition router, update firmware, switch channels, or upgrade to mesh Wi-Fi or business access points.
Bottleneck #4: Unauthorized Users on Wi-Fi
-
How to Check: Check the connected device list on your router.
Fix: Change your Wi-Fi password, enable WPA2/WPA3, and separate guest access.
Bottleneck #5: Outdated or Failing Network Equipment
-
How to Check: Inspect routers, switches, and cables for age or damage.
Fix: Replace old routers and switches, swap damaged cables, and keep firmware updated.
Bottleneck #6: ISP Throttling or Local Service Issues
-
How to Check: Consistently low speeds despite internal checks. Verify via your ISP’s outage page or support.
Fix: Contact your provider, or consider switching to a more reliable business ISP.
Advanced Fixes: Quality of Service (QoS) & Network Segmentation
What is QoS?
QoS allows you to prioritize critical traffic like VoIP calls, Teams meetings, or cloud apps so your business functions stay smooth even during heavy usage.
When Network Segmentation Helps
Separating guest Wi-Fi or non-critical devices prevents bandwidth-hogging distractions from slowing down business-critical tools. These advanced configurations often require professional setup for best results.
