Thanks. I think I will go with a wireless router. That way I can occasionally use internet on mobile phones too. How much will a decent one cost?
1100/- TP Link single antenna router.
Also, I am still not totally clear about how login in Reliance broadband will work. My perception is that if nobody is using the connection at a point of time, then any device can use the login credentials to connect. And when the second device needs to connect, then it won't need to login. Am I correct?
Yes, your perception is totally correct.
