Hello, I am currently using Verizon Fios as my ISP (Gateway router). I intend to add the TL-WR841N as my secondary router where I will plug in a TV streaming device to watch TV.
I do have a few questions.

-How can I set up the TL-WR841N as a bridge to my Primary FIOS router?
-I tried to use the western digital powerline adaptor to extend my network but lately this unit is causing issue with my primary router, slow and very unstable speed on both my primary and TL-WR841N unit. Can this bridge be set up wirelessly without the use or need of a powerline adaptor? Please advise how.
-Last question, the TL-WR841N will be connected to a VPN service via L2TP. If the above set up is possible, can I still utilize L2TP service for my streaming device?

Sorry, i am not a networking pro so pardon the dumb questions.

Thanks!
