Dreamcast can't connect to the internet

[The Mr. Video]

Hi, I haven't gone online with my dreamcast in a while, so I fired it up and tried to connect to the internet using Web Browser 2.0. When I tried to connect, it gets as far as connecting to the Dreampi, but when it tries to load a website it says "Unable to connect to host. Could not look up it's name." I also tried Quake 3, and it says it can't connect to the master server when it tries to look for an online match. I tried re-burning the Dreampi software onto the SD card, that didn't work, and I checked the internet settings on the Dreamcast, and all the settings were correct. The strange thing is that when I connected last time, it worked fine. Is this a problem with the Dreamcast or the Raspberry Pi?

what are you using for an LVI?

do both light on the modem light up?

have you changed your ISP or router or modem since it worked last?

did you try to manually connect to a quake server?

I use a homemade LVI that I never had a problem with before, both modem lights do light up, and I haven't changed routers, modems, or my ISP. What I didn't try was manually connecting to a quake server, I don't know how to do that though.

did you check the battery..?

Mine doesn't use a battery, it gets power from the Pi itself using USB.

Somehow re-entering the wifi names and passwords on the Dreampi got it to work. Now my Dreamcast is back online.

Nice! Welcome back!

Necrobump: I had to re-flash dreampi, and now the problem came back. Re-entering the wifi information does not work.

Edit: I figured out that I'm having the same problem that this thread is talking about, where my router gives my pi the same IP address as the Dreamcast. https://dreamcast-talk.com/forum/viewto ... 42&t=10318
