As written above, in Firefox select "File" -> "Work Offline". "Work
Offline" should now be unchecked and Firefox should now work properly.
For Konqueror I don't know a solution.
Do you use a "regular" wireless (wifi) or a wireless UMTS modem? A wifi-
connection should be picked up by network-manag
I made further experiments and partially solved the problem:
Start the (UMTS) modem, start Firefox, select "File" -> "Work Offline".
"Work Offline" should now be unchecked and Firefox should now work
properly.
Interestingly, most of the rest of my system reacted on this change,
too. Adept and Evo
