I posted this earlier in the networking forum, but I think it is also relevant here.  Let me know if anyone has any ideas:

 

Need some help on a DNS issue - stop me if you've heard this one before...

 

I recently resolved a longstanding DNS issue on my PC; I was getting "unable to resolve the servers DNS" messages, etc. While I _somehow_ managed to fix the issue on the PC, my son just got a Samsung Galaxy Tab4 which seems to be having the same issue. Actually, now that I check, the iPhones cannot connect but my iPad can connect. Not so much worried about the phones, but if I don't get his tablet online, and quick, I'm not sure what he's capable of...

 

I tried to change the DNS settings in the "Modify Network Config" fields of the Tab4:

 

I read that in order to change the DNS settings on the Tab4, you had to change from DHCP to static, so I did that. When I tried to change to the recommended DNS settings, the "Save" field at the bottom greyed out and wouldn't let me save the changes.

 

The settings are as follows:

 

Static IP - 192.168.1.111

 

DNS 1 - 192.168.1.254

 

DNS 2 - 8.8.4.4 - (this field is greyed out from the outset)

 

Anyway, any help on the matter is appreciated.

 

Thx,

I'm guessing DNS 1 is your gateway ip address. I am also assuming your static IP is outside the IP range that your DHCP server is using. DNS 2 is one of Googles DNS servers. Try changing DNS 1 to 8.8.8.8 . This is the other DNS server of Google.

Can't change the DNS fields....actually, I can change them, I just can't _save_ them when I change the numbers in the field.  The "Save" button greys out when I change anything in the DNS 1 field.  DNS 2 field is greyed out always.

If 192.168.1.254 is your router can you change the DNS servers in the router Web interface?

 

8.8.8.8

8.8.4.4

8.8.8.8

8.8.4.4

 

I suppose, but will that affect all the other devices?  Will I need to change them all, as well?

If your other devices are using the gateway for the DNS server then nothing changes. Even if you change the DNS servers on the router, the devices will still use the DNS servers in the Windows settings.  I am not sure of the Apple devices though. You router may have your modem IP address at the DNS server. Just make a note of what the ip is now so you can revert.

Changed the DNS settings in the router to no avail...

Sorry, I am pretty much out of ideas on this. When you tried connecting to the wireless network with the Galaxy, did it ask you to provide a password?

I figured it out - set all the devices, including the Galaxy, to the trusty 208.67.222.222 DNS; worked like a charm.  Thanks for your help...

Yep, I was going to mention OpenDNS but I saw that one Google DNS. I'm surprised Google DNS did not work though. Glad you got it sorted out.
