Hi all, can anyone help?

I am living in Cape Verde, Sal for six months of the year, I have internet although it's not great, the router the company supply is a zyxel, I have seen various tp-link routers in shops and businesses so I know I can use a tp-link routers on the island.

when I went through set up, it asks for the country and provider, however, Cape Verde and Alou or cv model are not listed.

Is there a way I can still use the to link archer vr400 router I have ? Can I set this up manually some way? 
appreciate any help, thanks
