No matter what I try, or the revision of OPL I use, I am unable to see my network share

[NerdcoreMC]

I know it works, I can pull up the shared area in SMS, but for some reason opl 0.8 doesn't show anything, and 0.9 tells me that I have an error:300. I have everything set up properly (open port listed, ip correct) Is it because I am not connected via ethernet? I am using wireless on my laptop, but that shouldn't matter should it?

edit: Even with ethernet in I am having problems. If it's not error 302 it's error 300. I have been trying to get this to work for about 10 hours now, and it's driving me insane.

Second Edit: Got it working with usb, so I know it isn't the games. No matter what I try I just can't connect. My router isn't running a firewall, and everything should be wide open. my PS2SMB is shared (Made a separate partition for it, even) I have the folder architecture proper and everything. OPL 0.8 shows nothing. Depending on which open port I route it through depends on the error in 0.9. I know both are open, because I checked for listening ports and all. I would appreciate any kind of help that can be given!

I really need something to go off of here. Having a slim I can't load from internal HDD, and I hear USB is a horrible way to play games. Can someone please help?

If you have an error 300, it means OPL fails connecting to your SAMBA/CIFS server, so it can be due to:
* bad IP address for your PC
* bad port
* false credential (or guest account not allowed)

What is the path from your PC to the PS2-slim? I know that you said Laptop-Wireless> Router... Network Patch Cord from Router to PS2? Are you sure it is Securely Plugged in? Have you tried using a different cord?

PS2 IP is something like 192.168.1.10. For ease, change it to +/- 1 from whatever you computer's IP is. Make sure that you change it in each application that needs to see your PC, and set it in Router. For mine, I use 192.168.1.103 for PC and 104 for PS2... also keeps housemates from asking what it is, as its next to my "Assigned" IP, they know that its mine.

I think OPL uses Port 445 to communicate with the PC, Make sure that your PC Firewall (Windows Security Center/Firewall???) is set to Allow it through. Windows Firewall allows you to set up the port to only allow a certain IP to use the port. I set mine up to Open Port 445 to 192.168.1.104, everyone else is blocked... Sharing the folder still allows people on my network to access the shared folder though.

If you have a Network Crossover Cord, have you tried direct connection from the PS2 to Computer?

And the silly question, Have you thought about possibly Modding your PS2-slim for HDD usage?. Google "Slim PS2 Hard drive" or "PS2 Slim HDD". Switch to Pictures for quick looking, or skim the titles for whatever catches your interest.
