Recently, I lost wifi connection completely on my XPS 8700. The computer cannot detect any router. I noticed that the Realtek wireless adapter was missing in the device manager. Fortunately, the Dell wireless adapter was still available. After enabling this adapter, wifi connection worked again. However, during this trouble shooting, I found that the aux_pwr light turned on even if I shut down the computer.
My questions are:
1. Is the Realtek wireless adapter dead?
2.Why does the aux_pwr light turn on - solid amber light? Is it related to the Realtek wireless adapter issue or it indicate some other issues in my computer?
3. Can I turn off the aux_pwr light or how to trouble shoot? I don't think the aux_pwr light on is normal.
So far, the computer is working fine. Surely, I haven't tested all functionality.
Any help is appreciated!
