ok this is going to seem complicated but isnt
go to start and in the search box type CMD. It will come up with a file named cd.exe
a black window will pop up with a dos prompt
type in ipconfig
a bunch of stuff will come up and most of it you will not need. What we need is
ipv4 address (example: 192.168.1.5)
subnetmask (should be 255.255.255.0)
default gateway (example: 192.168.1.1)
Write these things down.
Now lets go to the phone go into wifi in the system settings menu. The first thing we will check is if you are set to DHCP. Press and hold the network nae you are trying to connect to. a dialog will pop up to either forget the network or modify. Choose modify
click show advanced options
under proxy it should say none, under ip settings it should say DHCP. It either of these say something different, set them to what I have above and try to connect. If it connects, forget everything else I am going to type because we found the issue.
If they say that and you still cannot connect, change DHCP to static.
Here is where those numbers we wrote down come into play. under IP address we want to increase the last digit by 2 from the number we wrote down above (the example: 192.168.1.5 changes to 192.168.1.7)
under gateway, we want that to be the same as the number above (example: 192.168.1.1)
If the rest of the settings are filled in, leave them as is. If not, here are my settings to try:
network prefix: 24
dns1: (the same as your gateway above)
dns2: 71.242.0.12
key index 1
hit save and hopefully it connects.
If not, I got nothing else. I will be here all afternoon if you have a question
