Since forever, we've always used static IP addresses on the LAN for all hard wired PC's / Plotters / printers on the SOHO network (Small Office / Home Office). Most of the devices are laptops / TVs / Consoles phones, etc have their IPs assigned by DNS. All data is stored on one PC, backed up to another daily and backed up to Hot Swap drive for storage off site.

Just this morning, the local PC that receives the backups didn't run the backups scheduled for 5, 6, 7, 8 am schedule ... checking I saw, from the main PC, that the backup network drive was "not connected". Thinking I solved the problem, I noticed that the PC had been changed from a static connection to a DNS assigned connection and that the address has been changed from 198.68.1.4 to 198.68.37.110.

Looking at the router, I saw that the IP address for that PC was still the assigned value of 198.68.1.4 .... changing the unconnected PC back to the 198.68.1.4 / 255.255.255.0 and adding the typical default gateway and rebooting it did not fix it.

So I went to the 2 other active machines w/ static IPs on the network to check their settings and all of them were set to obtain and address automatically from router. One other thing I noticed was and extra Local Area Connection:

Local Area Connection 2 - Asus Router (GT-AC5300) * network map shows this one as the one being used.
Local Area Connection 3 - Network Cable Unplugged - Kaspersky Security Data Escort Adapter (Red X)

I had never seen that before, guessing it was installed with the latest update. Can't find any info about what it does or how it works but I did disable and uninstall it as a troubleshooting step ... and for a few seconds thought I had it resolved. As the machines was rebooting, the tray icon seems to indicate we had network access but after a few seconds the icon changed to no connection.

1. I can't imagine what would have caused all machines on the network to switch to automatically assigned IP addresses.

2. I get a "network path not found" when I try and access the drive which I am assuming that is not on my end but on the puter receiving the backups. All backups ran fine yesterday, but this morning that PC had no network access.

Every time the machine reboots, have to go thru this process:

1. Go change IP4 properties and change IP address to 198.68.1.4
2. Soft or Hard reboot router
3. Change IP4 properties and change IP assignment to automatically

Besides the problem on the SO side of the SOHO network, the HO side has been off .... my Linux Lappie no longer streams anything full screen; I have to shrink window to 4 x 4 inch to get away from the stop action animation looking thing. The Den TV's fire stick continually reboots id you move the cursor before a page finished loading and then even after.

If I can't resolve this soon gonna do a factory reset and see if it solves the issues but that's like a weekend headache

Any suggestions ?

Sounds like a Windows Update did something as you've got a new connection labeled #3. (On one of my older laptop computers I think it's up to 4 or 5).

Instead of assigning the IP address on the computer(s) let them get assignment from the router's DHCP. Log into the router configuration and go assign the IP address manually using the router (EDIT) with the computers' MAC address.
(I wasn't able to easily find a link with instructions but hopefully you can do this. If not I'll search again). Sometimes the DHCP server has a hard time with manually assigned IP addresses via the Windows settings. (I know the old days it worked just fine I used to do that so I wouldn't have to fix printer settings every time the computer reboot).

Crossing my fingers!

By the way the DNS server as I understand works to change your typed web address into a numerical IP address...

www.yahoo.com -> xxx.xxx.xxx.xxx

1. Windows update has never been "on" such as it auto installs anything ... most of the updates were manually installed with DISM++, these days are the Malware and AV updates

2. I set up this network n late 2013 so it's a bit foggy. Last time I had looked before this started abut 3 months ago, when I viewed the addresses in Windows, I saw:

"Use the following IP Address
198.68.1.4. "

When we tried letting the router assign ports to the MFP and Wide Format Plotter, assigning the ports at the router didn't work. We had to set them in the MFP / Plotter themselves. Oddly enough, the Canon MFP shows up in the router config, the HP does not.

Canon 5335i 192.168.1.215
HP 1055CM+192.168.1.216

Any suggestions on the sudden loss of usability with TVs and lappies ?

A few comments:

1. For the IP address range of all network devices I prefer the first three parts to be exactly the same:

abc.def.hij.xxx (where only the last xxx changes 1 - 254 if I'm not mistaken)
So if your router IP address is 192.168.50.1 (pretty common for ASUS all devices should have IPs that start with 192.168.50

I wasn't sure what you meant by "typical default gateway". If you meant the IP address to access the router then that is correct as far as I know.

If you had everything set up and working I would change the IP address of the router and range DHCP server to match what your current router uses. I think there are 3 settings to accomplish this.

At least for our new to us AXE16000 the device list is buggy. I have a Brother HL-1470N connected to a AXE11000 node and it sometimes shows as directly connected to the AXE16000 not the AXE11000.

My workaround was printing a test page from every computer I setup to use it.
