I keep an old laptop, Win 7, next to the bed for checking email. When it resumes from hibernation mode, the wi-fi doesn't work although it does see the signal. I have to reboot, then it works normally. Same if I start from scratch. Only resume from hibernation has this problem.

I suspect this is a known issue. Does anyone have a quick fix?

What does device manager show for the Wi-Fi module when this issue happens?

Installed the latest wireless drivers?

OK, I have only done this twice but it looks real: When I go to Device Manager and click on Network Adapters everything appears normal though I don't have a connection (the circle on the network icon keeps swirling). So I click on the adapter (Atheros) and then the Advanced tab. If I then click on Network Address, which is blank, it suddenly starts working. The Not Present box is ticked so the value remains blank, but the circle immediately stops swirling and I suddenly have a working connection. I don't think this is a coincidence. I will keep checking it to make sure.

Don't know anything about drivers. The laptop was a gift and I did not clean install, I just got rid of everything from the previous owner. I know that's not how you are supposed to do it but it's an old machine and I don't want to have to go through the hassle of finding bits and pieces for it for the limited use I want to make of it. So I kept the OS install and ran Defender and Malwarebytes and CCleaner to clear out most of the rubbish. It seems to work okay, except for the hibernation issue.

I vaguely recall hearing things about this at one point or another so I thought it might be a known bug with an easy fix. If not I will just live with it. It is not a biggie.

What about Device Mgr, Adaptor, Properties, Power Management - Set Don't allow it to be turned off to save power. Worth a try.

First thing is always to look for the latest network driver for the WiFi adapter.

That sounds good but it seems to be working again. Don't know why. I haven't changed anything but the last few times it has come on normally. I will wait and see.

I have an old but otherwise (mostly!) trusty Lenovo laptop that does this from time to time. Wireless is connected but no data will flow. Needs a restart to fix which isn’t a major due to having an ssd drive.

Of course it has latest drivers.
