So I've tried port forwarding before and it worked, but I've since changed my setup and now I have a modem connected to a router and it doesn't seem to work anymore. When I used to use only the modem it worked as a wireless router but I believe the signal was too weak for other devices so we got a Tenda router.
Now I'm looking for a way to change some settings or change the setup in order to be able to port forward again. Keep in mind I know only the basics. I'm willing to ditch the router if it is causing these issues.

Have you made sure the host has the proper static ip? Dynamically assigning it via DHCP using the mac address works well. The router might not accept a self appointed static. The host can't have a firewall blocking that port either.

Another thing to compare is the modems/router wan assigned ip against a website that shows your ip. The ISP might be running a NAT.

It sounds like your "modem" isn't just a modem. It is a combo modem/router. S9ou you would have to portforward on the modem/router to your new router and your new router would have to portforward to your end host.

You should check the user's manual for your modem/router to see if it can be used in a bridged mode. That would avoid having to portforward twice.

How would I port forward from modem to router, which IP and port should I use, and what would the end host IP and port be?

Port forwarding is used to reach hosts behind NATs. You have two NATs now.

It's ideal to only have one.

A few options are to put your modem into passthrough mode and setup portforwarding on the new router or to configuring the new router as a wireless access point, eg no NAT, no DHCP, no firewall.

I'm not too tech savvy so I would probably need step by step help to do it, but I can try turning it into a access point.

Try logging into it and seeing if it has any mode types.

Some of them will let you select WAP and it changes all the settings needed.

If you're still in the window to return it. You probably only needed a WAP in the first place, Unifi one's are great. Lot's of wireless routers have the WAP feature.

I've tried removing the router entirely and only using the modem but the issue persists. But it can't be double NAT can it? I have friends from the same town under the same ISP that are able to port forward without issues.

What you should try is to configure your second router as an access point rather than a router. Here is the sticky on how to do that -- http://www.tomshardware.com/forum/36406-43-convert-wireless-router-wireless-access-point

If the second router is an access point rather than a router, then you don't have to port forward through it. This is what @failboat said above.
With it configured as an access point, you would have only one router in your network.

I have successfully turned it into an access point, but the issue still remains, my port still isn't being forwarded.

I've done exactly that, but when I try to connect to the server or when I go to canyouseeme.org the results are still the same as before.
