Default [Q] Can't get internet from Galaxy S5 Wifi Zone

Hello.

Well, this is it.
Not much to say. I connect my Xperia Tablet Z (SGP311) to my Galaxy S5 Wifi Zone, the Wifi connection is made, the S5 has internet access (I can navigate, open Play Store, etc.), but my Tablet has no internet access. It happened in firmware 4.3, I updated to 4.4.2 but didn't help.
Any ideas would be appreciated.
Thanks and greetings from Uruguay!
