[specialistas4]

Δεν εχω δυο καρτες....

[logari81]

κι όμως έχεις. Η μία ειναι εσωτερική και η άλλη είναι usb. Τι είναι; φορητός;

[specialistas4]

Ναι ειναι laptop.Τα windows δεν μου αναγνωριζαν ποτε δευτερη ασυρματη καρτα!!!

[logari81]

στα windows συνήθως χρειάζεται να εγκαταστλησεις επιπλέον οδηγούς, στο GNU/Linux όχι. Τώρα δοκίμασε να συνδεθεις με την εσωτερική καρτα, δηλαδη με αποσυνδεμένο το στικ, και πες μας αν εχεις το ιδιο προβλημα.
