Well since your iPhone can auto-connect to other wifis then you can safely say that the problem isnt with your iPhone but with your router.
I would try to take any security off your router to make it public and see if that helps. Your router could also have an update for its firmware. If none of that works, I would get in touch with who makes your router and see if they can assist you with that or reset the router back to default and set it up again with you on the phone.

I tried again by keeping the router security off, but its still the same. Didnt find any update for router firmware as well. Will contact the router company and will get back to you. Thanks!
