Only chance without the remote is to use a wired connection (Ethernet) instead of WiFi, that's provided your TV has an Ethernet port of course. If router is nowhere near the TV, you can provide an Ethernet port next to the TV by using a pair of powerline adapters.
What's puzzling me is why you have no remote for the TV - - seems to crop up quite regularly on various forums - - and it's always Vizio televisions - - don't Vizio give you a remote with their TV sets
