If I want to log onto our WIFI network, Windows keeps asking for credentials. After many connection attempts (and sometimes some reboots) we finally manage to connect. Then the connection usually stays intact for the rest of the day. But it sometimes takes 15-20 minutes before we're online... Needless to say we're using a single username/password for all failing/succeeding attempts.
Does anybody recognize these symptoms? How to troubleshoot this?
The problem is somewhat complicated by our Windows being a Dutch version (not my choice). The window that keeps popping up is the following (perhaps I can edit it in order to translate...).
