WiFi Aid: Network Diagnostics

Slow or unreliable Wi-Fi? WiFi Aid runs network diagnostics to find the most likely cause, whether it is your router, DNS, your internet provider or a single website, and shows the evidence behind every result.

Stop guessing and restarting
Instead of rebooting everything at random, the network diagnostics check each layer of your connection separately: the network path, a DNS test, TCP and TLS checks, response timing and stability. Comparing the results side by side shows where the connection breaks down.

Run a Check
One tap tests Wi-Fi, DNS and internet connectivity together and gives you a result and a likely cause within seconds.

Deep Check
Collects more evidence and more stability samples, which helps with problems that come and go.

Check a Website
Enter any address to see whether a single destination is failing or the wider internet is having trouble.

Evidence for every conclusion
DNS, TCP, TLS, TTFB, HTTP, direct IP, IPv4 and IPv6 results are listed one by one, so each conclusion is backed by a measurement.

Stability and latency
Repeated sampling works like a running latency test, tracking latency and jitter over time. It reveals a connection that looks online but feels unusable, the kind of problem one quick test can miss.

Check History
Results are saved automatically, so you can compare how your network behaves from one check to the next.

When it helps
Run network diagnostics when a video call freezes, a game lags, one app will not load, or the internet slows down at certain times of day. It works as a quick WiFi checker at home, at work or on public Wi-Fi.

Private by design
No account, ads, analytics or tracking. Your check history is stored only on this device.
