Unstable wireless connections are usually due to one of two situations:
- low signal quality
- some sort of internal interference
If you suspect a low signal, start whichever wireless front end you have installed (such as Kwifimanager, Wifi-radar, or Wlassistant) to check the signal level. If the signal is low try to reorient the antenna (for example try to rotate the laptop 90 degrees) or get a better antenna.
For possible interferences, see this page.
