wifi keeps disconnecting

Along with a genuine WIN10 fresh install, I replaced a hdd to a ssd for my mom's HP laptop a couple weeks back and ever since, she's had a wifi disconnection issue but just in her own house's room. Watching Youtube it would stop, browsing the web - I think it says something generic about DNS too, but then I can reconnect to the wifi less than a minute later. Happens once every hour, half hour or so.

They have a Dell laptop 7ft away from hers that sits right next to the FIOS router using wifi that never drops. Also, my smartphone was still connected when her laptop dropped. You'd think it's her laptop issue, but here at my and another house, her wifi on her laptop never dropped. I went over there to reset her router but it did disconnect again. I notice she had it plugged into some makeshift extension cord box and that seems to be the only difference between their 2 laptops.

She then started using another outlet without an extension cord, and it drops her a lot less often, but it still drops her. Could this be an electrical issue at all, where the wifi antenna in the laptop is cutting in and out? New SSD-related somehow? I should also mention the laptop battery, though now always plugged into AC, doesn't hold a charge on its own anymore. The house too has had some electrical problems... I think it's only rated at 100 amps and when I lived there, my PC would sometimes cause electrical issues too.

Go to a CMD prompt and ping something like www.google.com and then ping direct ip of something like google dns 8.8.4.4. If the second works then the computer is suffering from a weird Win 10 bug where DNS is basically broken. I had a laptop that was going this and after scouring all kinds of MS support forums the only solution is basically to reformat and start from scratch.

^ thanks for that - but if that's the case, wouldn't a bug like that exist on all WIN10 installs, which the Dell laptop is also? Although, that Dell was a WIN7 upgrade, not a fresh install (from Media Creation Tool from MS like the problem laptop)

On a related note, since WIN10 free is over after tonight, if I revert to WIN7 (fresh), can I still use my USB stick (from media creation tool) to get it up to WIN10 at a later date for free since the laptop is genuine and had WIN10 on it?

No because it's a random bug that seems to happen after a certain update gets pushed through which means it could be related to the wifi card and since the odds are low of the card being identical on your two machines that is why you are not getting it on all machines.

As far as free Win 10 once you do the free upgrade you can install it on your machine as many times as your heart desires. The machine gets registered on MS servers so it will always activate without you needing to put in a key.

Well I've disabled the DNS Client service altogether - we'll see how it goes.
