Wireless broadband stopped working,can anyone help?

    Last week,my wireless broadband at home stopped working.
    The failure happened simultaneously on both my laptop and that of my housemate so we've ruled out problems caused by changed settings on the computer etc.
    Computer is still picking up an excellent signal and says its connected but I cannot access any websites.
    Our service is provided by BT (who have been utterly useless),Linksys is the transmitter and the modem is XYZeL (I think).
    The lights on the modem appear to be flashing incorrectly,could this be a line problem?

    Any suggestions would be greatly appreciated.
    Cheers

    I take it that your broadband is wired and your LAN is wireless? That's quite different from wireless broadband. Unless you got the wireless router from BT they can't, and shouldn't, provide any support for it.

    Can you connect the Zyxel modem directly to an ethernet card on one of the computers? If so, does your broadband work?

    Also, try to ping the wireless router or the Zyxel modem. Open a command prompt and type ping 192.168.1.1, that should work for the modem. If you get a response then the compoter is seeing the modem. Try to access the modem configuration screen by entering 192.168.1.1 in a browser window. Go to the diagnostics screen and run them.

    What lights are flashing incorrectly on the modem? There's an orange DSL sync light that should be on when it's connected to the DSL. There's a 10/100 light that flashes to show ethernet activity on it's port and an ACT light which flashes to show that data is being transmitted or recieved over the DSL line.

    Many thanks jor_el
    In command prompt I typed ping 192.168.1.1 and my result was: "Request timed out, Reply from 192.168.1.1:bytes=32 time=3ms TTL=64"

    I also tried to access the modem congiguration screen by typing 192.168.1.1 in the browser window. When I did this,a box appeared titled 'WRT54G" asking for my username and password which I entered but to no avail.

    I then checked the lights on the modem: DSL was green constantly, 10/100M orange constantly and the ACT was blank.

    I then tried connecting directly to the modem from my laptop but the local area connection did not work. The messages I got were that there was limited or no connectivity and the network did not assign a network address to the computer.
    I tried to repair the connection but this didn't work either.

    Any thoughts?

    Strange. I know that the default IP address for the Zyxel modem that BT supply is 192.168.1.1, so if the Linksys router, identified as WRT54G in the borwser is also 192.168.1.1 then that is a problem. Though how this was working previously for you I don't know, it shouldn't have been.

    When you tried the username/pass for the router what did oyu enter? Normally it's something like admin for username and 1234 for password. This isn't your BT broadband username/password. The manual for the router should give you more information on this.

    If both modem and router have the same IP then you need to change one of them. You should also dissable the DHCP function in one of them. I dissabled the routing and DHCP on my wireless router and let the Zyxel take care of everything. It's IP is 192.168.1.1 and the wireless router is 192.168.1.3.

    Without seeing your setup I'm at a loss as to what's gone wrong. I know the Zyxel modems do break down, mine did last week but I had a spare. Others have made claims that these are completely crap modems so maybe yours has just broken. If you can't get a connection with a direct link from laptop to modem then it could well be faulty. You did you a crossover cable to connect them right? The red cable that came with the modem should do. If you used a straight through cable (for connecting modem to wireless router) it wouldn't work.
