Wireless router works if wired won't work wireless

How many wired and wireless computers do you have ion the network.
Do you have any wired computer ?
Connect your laptop to the router with the Ethernet cable and try to access Internet. See if the wired connection is working or not.
If the wired connection is working then I think you will need to check the wireless settings of the router and the laptop.

How to connect to the wireless network

Sounds like a loose connection or a bad ground wire

computer says its connected to an Unidentified Network Wireless router not working

Try rebooting both the modem and the router. It could be that the modem didn't pick up it's ip number when the internet went down. Then try pluggint you computer directly into the modem first to make sure it is setup and working properly. Then plug in the router (to the modem) and the PC plugged in directly to the router and check.

Once you have it connecting at that point then check the wireless settings on both the router and the pc. Then enable the wireless on the pc, unplug the LAN and switch to wireless network on the pc and see if it won't work.

If it works plugged in on the LAN but then not on the wireless then either your configuration isn't correct (ie wrong gateway ip number...gateway should be the same ip number as the router...ie 192.168.***.***) or perhaps the wireless part of the router died. It is possible for the wireless to die and the LAN (hard wired connection) to still work.

Replacing the router will not have changed any settings in the camera. The IP address 192.168.0.253 is the factory default for the camera, unless you assigned a new one when you set the camera up.

This is a wired/wireless camera, and if you're trying to connect wirelessly you probably have a router setup issue. Like any wireless device, the camera needs to provide the right key to connect. If you haven't set up your new router's wireless security yet, or set it up with a different key than the old one, the camera won't be able to connect. If the camera's not on your network, you won't reach it and you'll have the problem you described.

The simplest thing to do is to start fresh. Reset the camera to factory defaults with its rear-panel reset button. The button is recessed and you'll need a pen or other object to press it for a couple of seconds. Connect the camera to the router using a cable, and you'll be able to reach it again on 192.168.0.253. Set up the wireless network in your router (assign network name, security key, etc.). Then go through the camera wireless setup steps so it can connect to your network and you'll be back in business.
