Problem using static IP address

[Orange Heart]

I've got a bit of an issue here. First of all I come back to my Dreampi setup that I'd done a few months ago, working fine at the time. Suddenly it's not working, and I figure out that it's because my dreampi was now using the .98 IP address and therefore connection was being refused to servers.

Therefore I followed this guide: https://dreamcastlive.net/pi-static-ip-address/
and I've actually ended up in a worse situation, while the dreampi lists no errors itself, and supposedly its connected to my network that I can tell using my router network page as well, but my USB modem now only shows one light rather than two, and therefore it's not even connecting to dreamcast services in the slightest and is immediately failing on dialing.

I've gone around in circles over the last two days repeatedly resetting it and making sure I've done everything correctly, it pretty much comes down to, either using the default easy connect method with a non static IP, that allows me to connect to dreamcast online, but does not allow me to make that final step into an actual game, or a static IP which straight up doesn't connect for some reason.

Things to know, I'm in the UK, using a PAL dreamcast, using BT internet with their standard BT homehub - connected via wifi (using DreamPi 3 kit, running latest firmware). Was working fine until a few months ago. Games I've been trying are Quake 3 and PSOv2

Any help would be appreciated!

just to clarify are you having an IP conflict with .98? Is some other device trying to use it?

[Holsten]

i suggest to set a static ip for the pi inside your router settings and not within the pi. i had the same issues.

[Orange Heart]

No other device is using .98 from what I can see, but the Dreampi itself is using .98. which is apparently something that shouldn't be the case.

And I'm not quite sure if that's possible on my router setup, I wasn't aware you could force a device to use a certain IP externally through the router. I'll do some investigating in that area, but it would be the most ideal solution as setting a static IP through the dreampi made everything way worse.

[Orange Heart]

Just an update here I tried seeing if I can change the IP through the router itself but while it seems to have that functionality, it doesn't seem to actually change the IP or do anything.

Are all your addresses on your network on the same subnet, e.g. the first three set of digits match? This includes any routers, modems etc. you may have. Do you have any options in your router to set the DHCP address range?

[Orange Heart]

Yeah they're all on the same subnet, the range is from 192.168.1.65 - 192.168.1.253 so quite a large range which the dreampi/dreamcast should fit into. I also went ahead and removed most of the other devices from the network just to make sure nothing was conflicting.

Can you use putty to log into the pi? I would first start with a clean flash and setup of dreampi then try the following commands:

Code: Select all

ping -c 4 www.google.com

If that succeeds, it means there shouldn't be a network issue and you should be getting two lights on the modem, so something else is going on.

If that fails, try:

Code: Select all

ifconfig

Under wlan0 you should see an inet entry, this is your IP address. It should make sense, i.e. same subnet, valid IP address.

Then run:

Code: Select all

route -n

There should be a gateway associated with wlan0 and it should be your modem or router IP address.

You could also try setting the DHCP range so that it excludes 192.168.1.99/98. Have it go 192.168.1.100-255 or something like that. Restart all network devices if you make that change.

[Orange Heart]

So, if I connect through the regular method, I've got no issues at all pinging google and I do indeed have two lights showing up, the problem is that while I get through all the steps of connecitng, it always fails on the last step (normally the 'authorisation' stage).

The only real option here I have is to play with the DHCP range so I'll give that a go and see what happens.

Edit: So at this point I feel like it's a router issue, while I set the DHCP range, and I restarted everything on the network, the dreampi still defaults back to the .98 ip regardless, even though its not within the range, in fact the same thing seems to happen to all devices. Not sure what's going on there.

Is it normal for the dreampi to always use .98? it's quite literally never ever any other IP

[SEGA RPG FAN]

It wants to use .98 by design. It's so you have a predictable IP address to port forward to. What do you have for your username and password in the dreamcast browser settings? It sounds like you don't have the issue you think you do. The authorization step failing means you probably don't have the username set right. it should be "dreamcast" for the username and password can be anything but I usually just use "dreamcast" as well.

Also, any game other than PSO or Q3 will need port forwarding to fully work.
