Hi,
Thank you Abraham, I try it. I think it is a hardware problem with the Wifi antenna. I made this test, I’ve put my tablet very close to my router, and the WiFi works well again. Some users reported this problem in other thread. I test this at my home and my parents home, so I think the problem could be related to the WiFi antenna.
By the way, I contacted to Teclast.es and they said they cannot support me because the tablet is chinnese version. I’m very dissapointed with that.
I answer again when I test what Abraham did.
Thank.
