Inspiron 1545 - Broadcom Gigabit Controller Not Connected - How Fix?
This laptop suddenly stopped connecting to anything 3 days ago. Since then I've confirmed that the wireless adapter is working (can see access points).
If I plug in a working ethernet cable there's no light at all.
Device Manager that's set to show 'hidden devices' shows the Broadcom 57xx Gigabit Controller as 'not connected, Error Code 45.'
How can I fix this? Is the device accessible without totally disassembling the entire laptop? Point me to some diagrams that show where it is and how to access it?
Or, is it possible to just leave it alone and get a USB ??? that takes it's place and allows Wi-Fi to fully connect to the internet?
Really need to get this machine working ASAP if at all possible.
Thanks,
Ken

If you are connecting to the internet over wifi, why are you concerned about your Ethernet connection?

Please re-read my post.
Neither a WiFi or an ethernet connection will fully connect to the internet. With wifi, I can see access points in the 'available connections' list but the laptop will not complete the negotiation to get an IP from the routers and fully connect to the router. Note: This is the same whether I use the internal WiFi OR a separate USB Wifi adaptor I have. This has occurred on multiple access points that the machine easily connected too a few days earlier. Plus, like I said, even if I plug in an ethernet cable no light comes on.
So, I began searching for networking components that weren't working and found what I described in my initial post. Can you tell me that the Broadcom Controller being 'disconnected' according to device manager has no impact on the machine's ability to negotiate an IP connection with various routers?

Thanks.
Can you answer my question #2? Is there a product that will work via USB ?
