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 220.127.116.11 to 18.104.22.168.
Looking at the router, I saw that the IP address for that PC was still the assigned value of 22.214.171.124 .... changing the unconnected PC back to the 126.96.36.199 / 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 188.8.131.52
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 ?
