Version: (using KDE 4.1.4) Compiler: gcc 4.3.2 OS: Linux Installed from: Gentoo Packages I cannot manage my D-Link DSL-504T router via web interface using Konqueror, because http server working on it returns page with message "401 Unauthorized Authorization required for the URL '/'." instead of authorization form. Other browsers (Arora, for example) work right.
It is not the only router device which has troubles with konqueror, see bug #177505.
Fixed in 4.2.1 or 4.2.0.
If this is still an issue in the recent versions of KDE, v4.6 and newer, feel free to reopen this ticket. *** This bug has been marked as a duplicate of bug 177505 ***
