Wired internet ADSL modem connected to Wireless Linksys WRT54G Router. I got same ping address 192.168.1.1 on both wire ADSL modem and wireless LINKSYS.

The problem is that the connection is not stable. It goes off when other computer is connected on the wireless at the same time. Is there any good software to monitor my home wireless network?

    What do you mean by ping address? 
    If both the ADSL modem and the WRT54G are using the IP Address 192.168.1.1 you have an IP conflict which will very much result in regularly dropped connections because either device will go "offline" at random.

        Both 193.* and 183.* are public IP Addresses probably assigned to your modem by your provider. On the internal network your modem should have 192.168.1.1 by default.

        Frankly it's hard to troubleshoot a modem setup with an additional router from afar especially with some providers using custom configurations and/or firmware on the modems. Also one has to understand that devices like the DSL805EU are not traditional modems but residential gateways that combine modem & router into one device.

        My first guess would be that your DSL805EU is configured as a Router that means it connects to the internet automatically and provides full network connectivity.

        My first question would be if you can access the internet if you connect your computer directly to the DSL805EU (wired). 
        If this is working you only have to make sure your WRT54G is configured correctly.

        Basically you will want to set the Internet Connection of the WRT54G to automatic and connect the WAN/Internet port to the ethernet port of the DSL805EU. This should ensure the connection between the modem and the WRT54G.

        As for the network setup of the WRT you will want to use an IP range different from the modem for example 192.168.0.1 with Subnet Mask 255.255.255.0 (restart required). 
        DHCP and Wireless settings can be setup as you wish or as you already have on the WRT54G.

        The key is having a working connection between the DSL805EU and the WRT54G. You can see this in the status window of the WRT54G ~ it should have an IP Address similar to the modem e.g. 192.168.1.2 and the modem IP 192.168.1.1 as gateway.

        Once this is working there should be no problem accessing the internet both wired or wireless.
