IP configuration not valid - interference from ethernet adapter?
Hi guys, I have a self built desktop that I only connect to the internet with using WiFi. But lately the connection on this PC is very intermittent and this is the only device in my house with this problem (so it's not the modem/router?). My PC has an Asus P8Z77-V motherboard with an Intel 82579V ethernet adapter and a Qualcomm Atheros AR9485 Wifi adapter, and I am running W10. Admittedly, I don't know much about networking but regardless this problem seems mind boggling!
Many times throughout the day my wifi connection will become 'Limited' and I cannot access the internet. I've noticed that during these times my IP address assigned by DHCP will be some useless 169.x.x.x number, but the strange part is sometimes the problem can be fixed by disabling my Intel ethernet adapter in Device Manager. Of course this is only temporary and I have even 're-fixed' the problem by enabling the same adapter after I have already disabled it.
I have even tried disabling the ethernet controller in BIOS in a moment of frustration but it didn't have any effect.
Windows troubleshooting gives me a variety of messages, most often 'IP configuration for wi-fi is not valid'. I suspect the ethernet adapter is interfering with this somehow but the troubleshooting application has also told me my security settings for the network are wrong, which I know they are not, or that there is a 'problem with the wireless adapter or access point'.
Thank you for any help you all can give! This is driving me batty
Here is my ipconfig /all while I have managed to have my wifi working (this time with the Intel ethernet adapter enabled).

And here is that same instance after it stopped working (no wifi).
