123 and verify that only periods (.) are entered. Any space (%20) or comma (,) breaks the IP format. The exact URL is http://192.168.1.1.

Mobile Keyboard Comma / Space Error
Why It Fails: RFC 3986 specifies commas are sub-delimiters, invalid in IPv4 literals. Mobile browsers treat the input as a multi-word search string.
ERR_NAME_NOT_RESOLVED loop.
http://192.168.1.1/
RFC 1918 Private IPv4 Socket
Why It Works: Exact dotted decimal numerical IPv4 socket. Standard gateway for All iOS Safari & Android devices.
How Mobile Keyboards Corrupt Router IP Addresses
Touchscreen keyboards employ predictive text algorithms designed for English sentences, not numerical IP routing. In iOS, typing two spaces automatically inserts a period followed by an invisible space. In Android Gboard, the comma key is placed millimeters away from the dot key on compact screens. When an IP contains a comma (192.168,1,1), the browser fails DNS parsing immediately.

Tip for Mobile Users
Save http://192.168.1.1 as a bookmark in Safari or Chrome on your mobile device. That way, you will never need to manually type the numerical IP address on a touchscreen keyboard again.
Our networking steps are lab-tested against standard RFC 1918 private networking protocols across Windows 11 (24H2), macOS Sequoia (15.1), iOS 18, and Android 15. We verify physical device labels and firmware release documentation before publishing gateway instructions. Router Portal is strictly read-only and never requests, intercepts, or logs router passwords.
