wlan - problem with certain routers, no connection possible

Hi,

i'm trying to connect to the internet from my Laptop (Dell Latitude E5510) using an O2 6431 Router (WPA2 PSK).

Though the wlan connection seem to be successful, i can't connect to the web, not even to the router's config portal (can't even ping the router's ip ...)

I'm using NetworkManager (i like NetworkManager, and want to keep using it ...)

Yesterday evening, everything was working fine, and, using my ipad, i can connect without problems.

Right now, i'm using my other (android-)tablet's mobile hotspot, and there are no connection problems as well. Eduroam works when i'm at university, just with that specifc router,
things don't work out well. I had the same problems last week, but one day later, the problem was gone, though i can't tell why.

Everything seems to be just right, no deviation from  the "usual" state ... that's why i'm pretty dazzled right now ...

The WLAN Led is permanently blinking, but it has been like that for quite a while, without problems ...

Default route is present.

I can't remember having installed/experimented with a different (conflicting) network configuration tool, and i can't see any related processes, either ...

My card:
