Browser Online Status Test
Use this to separate a completely offline browser from a slow, unstable, or app-specific connection problem.
Ready
DeviceOK measures browser-visible connection hints and HTTP round trips to DeviceOK. Throughput samples use small HTTP transfers to DeviceOK and are useful for quick comparison, not ISP speed certification. This is not an ICMP ping, local-network scan, or VoIP/RTP jitter measurement. A public IP can represent a VPN, carrier gateway, proxy, or shared NAT rather than a physical device address.
The test makes small requests only to DeviceOK and does not inspect your local network.
Use the result as evidence, not a guess.
- Browser online state
- Connection hints where exposed
- DeviceOK round-trip timing
A successful round trip proves this browser can reach DeviceOK.
It does not prove every website/service is reachable or measure Wi-Fi signal quality directly.
