    I'm having a problem with my internet connection via wifi. One day my laptop simply refused to connect. The day before no problem. I can connect by using the LAN cable, directly connecting into ADSL router, but when I try without the LAN cable plugged in, via wifi, there is no connection. What I have also noticed is that the Ethernet adapter, Broadcom NetXtreme Gigabyte Ethernet, v. 8.48, does not appear/load when I am not plugged in via cable. This was not the case when everything was working fine. Even to the point that it appears when I am on cable, but when I disconnect the cable, the Broadcom card disappears from my Device Manager.

    I have tried to update the driver, but cannot find a higher version than 8.48 anywhere. Note that in the 2nd case (with LAN cable), the Broadcom Ethernet adapter appears, while in the first case it doesn´t.

    Any ideas on how to resolve the Ethernet adapter issue? I could not really figure out how to update the driver properly. I tried downloading it from HP, but the system says it cannot find a more recent version, or even the one I have now.

    Here is my Ipconfig for both cases:

    Hi there,

    at first check out those possibilities:
    When you open your network connections and go to the properties of your Lan-Connection (Cable) uncheck the box in which is says that you should be warned if this connection has low connectivity. Do that also at your wifi connection.

    After that deactivate your Cable connection if you try to connect via Wifi.
