Facing TV Problems? Ask a TV Technician.
I'm reviewing your details and will reply shortly.
The TV itself has no bearing on the Roku picking up Wi Fi or not. That said, I need to ask you some questions to figure out what the problem is.
1) Which model Roku is this (1,2,3,4 - stick)?
2) Was it working before and then stopped?
3) What exactly do you see on your TV screen?
Simply send a reply back if you need help?
Okay, so did the issue occur right after the new modem was installed??
Because when a new modem is installed, you need to reset the Roku to factory defaults and set it up from scratch/enter the new model info. Did you do that?
No sir, I cannot do that. Note that the site will send you a phone call offer- that is NOT from me. It is sent without my consent and I am not available by phone. To see MY REPLY, "X" out of the offer and view the page that we have been typing on. Also note that any offers for subscriptions or promotions are NOT something I am privy to. I am an independent tech and am only paid with a positive rating for my service. If you understand, please simply say "I Understand" on this page, and we can continue with your Tech issue.

Since you're unable to reply to me, I will assume you do not need my assistance. I will opt out and open the question up for other experts.
I apologize that you had to wait a long time for a response.
Please let us know if you still need help with your question and if I am not able to help you, I can send it to other experts that can help you.
