Computer Internet Suddenly Slow
Web browsing, streaming or downloads have become noticeably slower on this computer than they used to be, or slower than other devices on the same network.
Quick answer: If it's slow on every device, that's likely your internet plan or provider. If it's slow on just this computer while others are fine, that points to something on the computer itself — background downloads, a weak Wi-Fi signal, or an adapter issue.
Likely causes
- Background programs or updates consuming bandwidth without you noticing
- A weak or congested Wi-Fi signal specific to where the computer is located
- An outdated Wi-Fi driver limiting connection speed
- General computer slowness (not actually an internet problem) being mistaken for a slow connection
What you can safely check yourself
- Run a speed test on this computer and compare it to a speed test on another device on the same network
- Check Task Manager for anything using significant network activity in the background
- Move closer to the router temporarily to rule out signal strength as the cause
When it needs a proper look
If a speed test confirms this computer is genuinely slower than other devices on the same network, and background usage doesn't explain it, that's worth a proper look at the adapter and driver.
