    I have intermittent WIFI connection problems as the DNS-lookup fails. Not always however - about half the time. I seen that other Samsung users also have the same problem. I am pretty sure it´s not the router as I have a Windows lumia 640 connected and it never has had problems. I did a factory reset a couple of days ago but that didn´t help either. It´s stil soemtimes yes, sometimes no. Can anyone help me with a solution? Thanks in advance

    Welcome to Android Central! I have found that the router can still be the problem, even when other devices connect fine. Try rebooting the router by unplugging its power, waiting 10 seconds, then plugging it back in again. Also make sure that the router firmware is up to date.

    Does this happen on other wi-fi networks?

    Hi B.D - Thanks for taking the trouble to reply. I´ll Try the router as you suggested. I don´t use the tablet much outside the home but in the cases I have it didn´t give any problems, which I assumed it was either the router or the tablet. As the router causes no problem whatever with telephone or tv I assumed it must be the tablet. I´ll try the router as I sais. THanks again.

    You have intermittent Wifi while other devices work fine, the problem is not from router if you have similar problem with another network.
    Try use another network, if it's the same, you need to change the main board as Wifi is built in on the main board.
    A working one costs only around $80
