The DEP, yah I had to do that to fix my error with ranged attacks. It isnt a psobb.exe error. The affected player freezes and after a bit will get a No100 no connection error.
1) Do you have a bunch of phones and tablets and shit idling on the WiFi? Each device makes a WiFi connection less stable, because of how WiFi works,
even if they're not actively using the connection. Basically, every device gets a "turn" to "talk" and only one device can talk at a time. So if you've got a bunch of phones idling on the WiFi, they will all be allocated a "turn" every few milliseconds, slowing down everyone else. So while you are playing PSO, turn ALL your other WiFi devices OFF, and ONLY leave the 4 laptops on. Keep in mind that some devices (such as a Wii), depending on how you set them up, will idle on the WiFi even when you turn them off (since it's not actually "off" but is simply on "standby"). If you have devices like this, either fix the setting or unplug it. Here's a long answer:

2) PSO doesn't use a lot of bandwidth, so your friend's operating system or possibly your router might be "deprioritizing" him. Try running some low bandwidth programs in the background to stop this from happening (Skype on idle, "ping
www.google.com -t" etc). Back when I used to tether my smartphone to play PSO, if I didn't have stuff running in the background my carrier would go "oh you're barely using your connection? Okay here have 500+ms ping since you're not using it"
3) Is your WiFi set up to use 2.4 Ghz (old) or 5.0 Ghz (newer)? 2.4 Ghz is more reliable. I had to turn my 5.0 Ghz switch off because it would have like 5x more packet loss than my 2.4 Ghz switch. Even though 5.0 Ghz is "newer" it has tons of issues (packet loss and inability to penetrate walls effectively being two of them).
4) On 2.4 Ghz make sure your channel is NOT set to auto. Make sure it is set to 1, 6, or 11. Those 3 channels are the only 3 channels that don't have any overlap. Use a program like Vistumbler to see what the networks in your area are using, and then pick 1, 6, or 11 based on what is least saturated. When looking at your neighbours WiFi, keep in mind that anything on channels 2, 3, 4, and 5 are going to overlap with channel 1 and 6, and anything on channels 7, 8, 9, and 10 are going to overlap with 6 and 11. Signal strength is also relevant (stronger signals will interfere more than weaker or almost undetectable ones). Here is an explanation of "why 1 6 and 11"

If none of that helps then idk lol.
