Selective WiFi malfunction

Greetings guys.. A few days ago I traveled to to my wife family residence. I tried to log in my XZ to their DSL broadband. WiFi and noticed that I got IP connection failure. I checked the connection and it's unable automatically generate an IP. I TRIED to modify the settings by clicking the. Static instead of the DHCP.. But when. I tried click Save. It becomes shaded.. So I was unable to connect to the broadband connection.
This is the first time that happened to an Xperia device.
Does anybody have similar experience like this,, where your gadgets have Selective WiFi connectivity..?
Is this related to nougat update as my previous Xperia are kit kat and marshmallow OS....? 2

Re: Selective WiFi malfunction

To set a static IP, you need to know what to use for that specific router so there's no general static IP-settings that will always work i'm afraid. You need to know what IP-range that is used by the router and the routers IP address. If you don't know what IP-addresses that are already in use on that network there's also a risk that you set an IP already in use which will not work either.

 

With that said, most consumer routers i've seen are by default on 192.168.0.x or 192.168.1.x range. I have seen other ranges used by default as well though.

For 192.168.0.x, valid settings would be:

IP address: 192.168.0.x where x is a number between 2 and 254

Gateway: 192.168.0.x (this is the IP of the router, usually x is 1)

Network prefic length: 24

DNS 1: usually can be set to same as gateway or you could use Google DNS, 8.8.8.8

DNS 2: Not necessary but if using Google, can be set to 8.8.4.4

Re: Selective WiFi malfunction

have you tried connecting to the router while on safe mode?

 

try to restart both router and phone, and try to set up connection again

Re: Selective WiFi malfunction

Sorry to hear that you were unable to connect with WiFi.

I'm afraid it's hard to say what might have caused the phone to not get any IP from the router but if it works with other networks i would not suspect there's anyting wrong with your phone. Possible reasons are that the router was not set up with DHCP or that it had MAC-filtering enabled. Later versions of Android also has a new DHCP-client. I've seen a couple of cases where it was needed to switch back to the old one from the phones developer options with a certain router.

 

If "Save" is greyed out when you modify a network to a static IP, please make sure that you have typed in a valid IP-address. It might also be prefilled with an IP when you select "Static" but you still need to type one in yourself to be able to save.
