Please tell me solution fast !!

Answer 1

first of all turn off ipv6 .because reliance is not giving ipv6 internet connection.i think you have problems regarding your ip address. restore default your routers setting or contact your isp customer care.they might fix it up with no charge.

Answer 2

Make sure the direct Ethernet cable from te modem is in the Internet port for the router then hook ur pc up to the 1 slot in the router. That's all I can think of. Or maybe ur router is on standby

Answer 3

Go to your start menu and type "Manage Wireless Networks" (Without the quotes) and press enter. Right click on the wireless network that you changed the password for then try to connect again, you will be prompted to enter a password now and can put the new one.

Answer 4

Hi friend, Check the settings.





Thanks
