I can't get it to work... Please help me!

Here's what happens to me. When I go from the title screen to Multiplayer, after the screen with [Multiplayer], the one with the "Do you wish to proceed?", the game pauses for while and then says "There was a communication error." then gets stuck there. It does not freeze as the background is still animating but none of the controls except home button work anymore.

When I go from the title screen to Mission List, when I get to the start of the mission (I mean the actual start as in the one where you move around already), it also says "There was a communication error." and the signal icon in the upper right corner indicates no connection.

I must have done something wrong but I can't figure out what. In my router, I enabled DMZ with my PSP's IP, disabled UPnP, even set authentication to open, and reserved IP for PSP (192.168.0.5). In my PSP, I put the IP (192.168.0.5) that shows up on my network settings in the server.txt (says 192.168.0.5 while my router has 192.168.0.1). I put the right SSID in the hotspot.txt (DIR-600). All Pro Online files are in the right place in my memory stick. In the advanced settings, I have NoDRM Engine disabled, Inferno & NP9660 Use ISO Cache disabled, Force High Memory Layout enabled.

I should probably specify that my router is not connected to internet as I don't have a modem and I use my Galaxy S4 for internet. I bought the router specifically for connecting my PSP and my laptop. I tried connecting my S4 and laptop and it does work but I can't get my PSP connected.
