Bonjour,
depuis que je suis passé à Ubuntu 18.04 TLS (clean install), le connexion avec le routeur wifi de mon appartement est intermittent : régulièrement (> 3 fois / jours) je ne recois / n'emet plus rien (syndromes typique : chat qui s'interrompt, mails qui partent pas, vidéo qui ne chargent plus etc.)
J'éteint le wifi de mon ordi et rallume, me reconnecte au routeur et ca repart.
Précision:
- cela n'arrive pas sur le wifi de mon université
- ma collocataire qui est sous mac n'a pas ce problème.
Voici le résultat du wificheck
