How can I upgrade my router if I have optik TV?

[wireless]

I have a telus T3200m router and I have been having problems with port forwarding on it for over a year now (see below link for info). Regardless, if I wanted to upgrade my router, what could I do to make sure optik TV still works, but also make the new router work (and hopefully be able to forward ports). I have fibre internet by the way. My I don't have a lot of knowledge about this type of thing, but if anyone knows how I could go about this I'd love to know. If I can't upgrade please refer to this post https://forum.telus.com/t5/Internet-...00M/m-p/117615

Thanks in advance.
