Slow Internet or Network Speed
Connected but pages load slowly, calls buffer, or downloads crawl
⚠ Common symptoms
- Web pages take more than 5 seconds to fully load
- Zoom or Teams calls keep pixelating or dropping out
- Download speeds are a fraction of your internet plan
- Other people on the same router seem unaffected

1
Establish a baseline with a speed test
Go to fast.com or speedtest.net and record your download speed, upload speed, and ping. Compare against your plan. If you're getting below 50% of what you pay for, contact your ISP. If your speeds look fine, the slowness is application-level, not network-level.

Find which app is eating your bandwidth
On Windows: open Task Manager (
Ctrl + Shift + Esc) and sort the Network column descending. On Mac: open Activity Monitor → Network tab. Common culprits are Windows Update, OneDrive, Dropbox, antivirus cloud scans, or video streaming in a background tab. -
3
Test with a wired Ethernet cable
Plug your laptop directly into the router with an Ethernet cable and re-run the speed test. If speeds jump significantly, Wi-Fi is your bottleneck — not your ISP or device. Common Wi-Fi killers: thick walls, distance, microwave ovens, and neighboring networks on the same channel.

4
Switch Wi-Fi band or channel
Log into your router's admin panel (usually
192.168.1.1) and try switching between 2.4 GHz and 5 GHz. Also try changing the Wi-Fi channel — for 2.4 GHz, use channels 1, 6, or 11 to avoid overlapping with neighbors. -
5
Turn off Delivery Optimization and background sync
On Windows, search for Delivery Optimization in Settings and disable it — it silently uses your upstream bandwidth to share Windows updates with other PCs. Also pause cloud sync apps like OneDrive, Google Drive, and Dropbox during work hours.
Quick win: Move within 5 meters of your router with a clear line of sight. A single concrete wall can cut 5 GHz speeds by up to 70%.
