Per riconnettermi a rete wifi devo riavviare il computer

Ciao a tutti, ho un problema con Ubuntu 14.04 LTS riguardante il wifi, che non accade su reti domestiche, o comunque altre reti (per quanto ne sappia). Devo usare una rete pubblica, accessibile a seguito di login dal browser. La connessione però a volte salta e non riesco a riconnettermi a meno di
riavviare il computer
. Capisco che la disconnessione può essere un problema della rete stessa, ma perchè per riconnettermi devo riavviare? Faccio presente che questo non accade in ambiente OSX, Windows o Android. C'è un'altra soluzione al riavvio?
Grazie!

In futuro ricorda che nelle sezioni di supporto è meglio usare i tag codice e non gli spoiler. Grazie.

Questo tipo di reti a volte dopo il login, modificano i parametri della connessione (gateway proxy dns cookie...)
Dovresti verificare queste impostazioni, prima della connessione e dopo la connessione, ovvio che facendo reboot rifunziona, ma probabilmenrte basterebbe resettare il parametro cambiato
