I have three laptop pcs of varying ages - one brand new, the others 1-3 years old. They have been working fine with my Netgear 7500 router.

Out of nowhere, two of them (for sure - not sure about the third as I do not use it as often) have been giving me trouble.

The older of the two (that isn't a factor, it is still maybe 2 years old and is a gaming machine and still very fast/relevant/uptodate) is doing worse. It drops connection daily. My younger son uses it and in the morning it will have lost connection overnight.

Usually it SAYS it is connected to the wifi with no internet.

At the same time, you can easily access internet via iOS and my wife is still using Netflix and other internet devices with no trouble.

Up until a few days ago, my son and I could use minecraft on the local wifi and he would start up and open a world to lan and I could find it (it automatically showed up on my machine - the new one) and play over lan. USUALLY it was fast and solid. Recently it started to give me some stuttering. Now it doesn't find the world at all.

We are all on the correct wifi access point. I don't know of any ap isolation going on.

I don't understand why it was working FINE and just quit. And other devices are connecting fine.

Here's a data point. I'm on this computer now. A few minutes ago, no matter what I did, including rebooting, I couldn't get to the router even though it SAID I was on the wifi with no internet. So, I picked up an ipad sitting in the same chair and did a reset of the surfboard modem using the 192.xxx.x.0reset.htm or whatever it is that resets the modem. Then I loaded the netgear router page on the ipad and hit reboot the router.

Once the router and modem were rebooted, I am able to access the internet just fine (haven't checked to see if I can minecraft across lan or not yet).

So what could this be? I went in to see if there were any killer bigfoot drivers and it appears that this is not using any. I don't understand WHAT CHANGED? I'm betting windows did one of its nightly updates and wiped something out - but WHAT? I am fairly savvy and can change it back but I cannot figure out what is doing this? I guess I'm going to have to make a couple of ipad icons to reset the modem and router so my son can just do that each morning, but it is very frustrating to have $5k in laptops that were working just fine a few days ago, CRIPPLED - apparently by MS. At the very least, they don't make it at all easy to fix the problem.

I could do a rollback to a previous time when it worked, but eventually it will update and screw it up again I expect.

This is incredibly disheartening.

TL:DR My PC's have suddenly required daily resets of the cable modem and netgear wifi router to connect to the internet. At the same time, other devices like roku, oppo dvd players, smart tvs and ios devices have no trouble - they connect just fine.

I'd say it's a problem with your router. Is it running hot? Most routers aren't designed to have a good ventilation, let alone a way to clean the insides, it may just be that it's running hot and isn't able to handle it. Ir it may just be dying and it's time to get a new one. But I'd check how hot it gets first. I don't think it has anything to do with your devices if nothing has changed (unless one of them had any kind of firmware/software update that could somehow be causing this).
