win7 losing internet conn after reboot

[dblake2]

Local telco cable modem with netgear router
I have multiple os on this computer, xp-32bit, win7-64bit, win10-32bit,etc.
This problem only affects win7-internet conn is fine in xp & win10 so pretty sure problem with win7 config, or losing its config.
win7 keeps losing the internet conn.
I restored recent backup & conn was ok-rebooted & conn gone.
I've since done this 3 or 4 times & get same result:
internet conn ok immediately after bu restored but goes away as soon as I reboot back into win7.

Hi dblake2,

Did you try using the built in network troubleshooter?
If you can connect via Ethernet/wired, can you reboot & access internet?

the troubleshooter was no help.
I got it back by restoring an older (2 weeks) backup.
so far its been good thru 5 reboots.
I did disable most of the adv system care cleanup stuff which is my best guess of the culprit.

try to use inconfig to check your network. or update the network drive
