but the wifi doesn't.

But it sure looks like it is connected and with good signal strength:

wlp3s0 IEEE 802.11bgn ESSID:"INFINITUMx2re"
Mode:Managed Frequency:2.437 GHz Access Point: D4:40:F0:91:1D:50
Bit Rate=11 Mb/s Tx-Power=17 dBm
Retry short limit:7 RTS thr:off Fragment thr:off
Power Management:off
Link Quality=70/70 Signal level=-30 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:8 Missed beacon:0

Perhaps you can expand a bit on what you mean by "...wifi doesn't."

We see nothing whatever wrong here, so you'll have to tell us in detail what is not working.

Yes in fact, the router is just one room away,
please forgive me, english is not my native lenguage
Well, i can connect and disconnect to my home network "INFINITUMx2re" easily, but i'm not still be able to load any webpage from any browser included in this copy of ubuntu,
only being wired connected i can
pd: i'm gonna correct the thread's mistake thanks
