Hey Guys,
So my school has this problem with their network. When a WiFi device such as a computer connects to it, instead of assigning an IP address like 192.168.1.24, it will assign 192.168.0.24. This will prevent internet access because the network doesn't use this configuration. It will also assign duplicate IP address. The lease on the IP is 8 days. I have no idea what's going on. The router IP is also not right. Please help.

I would need the model number of the router to look up any specifi cofiguration settings. Are any of the pc's on the Ethernet experiencing p roblems? Have you tried setting a static ip address and dns on a wireless computer correctly ex:192.168.1.*** and seeing if you have access to your network And the internet
It appears your subnet mask is different in your dhcp server (your router). Your network 192.168.1.1 has a subnet mask of 255.255.265.0 if the router assigns 192.168.0.24 the subnet mask would be 255.255.0.0. If the subnetmask is not defined some routers have default settings (Cisco) that it will assume. If your subetmasks are the same on both networks then there is another configuration error.

192.168.0.0 is the start of the class C private addressing so the subnet mask could still be 255.255.255.0 My first though is just a simple configuration error. Almost sounds like they used a wireless router to extend the wired netork and someone forgot to turn off the the DHCP in the wireless router. Either that or they left it on the default password and someone is playing games. A router make and model would be helpful to know what we are dealing with.

Hello again,
I'm sorry, but as of now, I'm not sure what equipment my school is using. I'm a student there, but the school has me help them and manage parts of their network instead of a Tech-ED class mostly because what they are teaching is bare-minimum word processing skills which I fly far over for my age. But anyways, when I go back to school Tuesday, I will get every piece of hardware they use marked down.

Thank you so much for your quick reply!

Regards,
Eric Bennett
