Presume you have a laptop, to use with the above BB connection, provided by BSNL.
PPPoE: to avoid confusion :
"Dialer Mode" You have to log in , with your ID/PW in a system Window
to connect to Internet.
PPPoE"Always On" mode :
Your userId/PW entered/stored in WAN menu page of your modem, and you get connected , as soon as you switch on the system laptop/modem/router.
An Id called SSID will appear in your laptop . ( this may require a security key to get connected ) Also some other WIFI connections may
appear which you may /can not connect if "secured"
Para two:
(1)
To get connected to BSNL BB, in other Devices/laptops/smartphones etc select the PPPoE" alwaysOn " mode.
(2)
Check settings in your modem/router with this link.
(3)
Also enable DHCP ( usually in LAN page) and give a range say 192.168.1.3 to 192.168.1.20
(4)
Enable UpNp button , if seen .
SAVE . Go to management and SAVE/REBOOT. wait for two minutes.
Para three:
(5)
Check laptop works ( connects to Internet)with RJ45 connected and in wifi ~~~ mode without any connection.
Confirm SSID say "Harmanjit" appears in other Devices.
Regarding TV with built-in WIFI, simply could have addition wireless Lan card incorporated. ( consider it as another laptop computer.!!)
