What does it say with admin Command Prompt  NOT POWERSHELL

C:\WINDOWS\system32>netstat -b -o -a -r -n

I normally disable IPV6 and ISATAP and Teredo.

I also TURN OFF update strangers on the internet for windows update.

I also TURN OFF All live tiles on the start menu.

netsh int ipv6 isatap set state disabled
netsh int ipv6 6to4 set state disabled
netsh interface teredo set state disable

My ethernet adapter is set up as "public" so I should be hidden. Today I'm getting pinged (9 times an hour) by the public IP address automatically assigned to this PC when I booted it today and also by 169.254.13.148 which is a bogus IP address. So I'm clearly being seen, but at least the McAfee firewall is blocking them.

My ISP shrugs and says I should connect the PC to a WiFi router and not directly using ethernet. So what was the point of them installing a FiOS ethernet port in every room when this house was being built...?

 

 

169.254.XXX.XXX  means it cannot find DHCP server.

This is the fail over position for windows.

127.0.0.1 is loopback.

Qualcomm QCA9377 is 802.11 AC and Bluetooth built in.

So the driver for this device is borked.

802.11ac combo SoC Bluetooth 5

 

Key Negotiation of Bluetooth (KNOB) attack, the vulnerability could allow remote attackers in close proximity to targeted devices to intercept, monitor, or manipulate encrypted Bluetooth traffic.

The Qualcomm WiFi+BT driver works fine. It connects to my WiFi router on either 2.4 or 5 GHz. The problem is the signal is weak because my router is on the second floor. I need it up there to connect to a lappy, cell phone, e-reader, etc - things that don't have an Ethernet port and tend to migrate up to the third floor. So it's easier to connect the desktop PC directly to the Ethernet port next to it on first floor.

Turns out one of the IPs that's been pinging me, not just my own assigned IP, also belongs to my ISP. They finally looked and found that one of their other customers has been "probing" their network. Guess that's a polite way of saying it's a hacker looking for unsecured devices. They promised to put a stop to it so we shalll see...
