So, as the title says, my desktop disconnects from Wi-Fi exactly every 30 seconds, like if there's a software doing that on purpose. It started about 7 hours ago, I had already been using my pc for 3 hours and all I did was starting another match on the same game I've been playing the whole time, nothing different. For the whole match I experienced lag. That kind of lag where everything freezes for almost a second and then it reconnects. It usually happened to me once per hour or so, but since that match it happens every 30 seconds, even while not playing. I tried a bunch of things and nothing seemed to help. Also, I bought a LAN cable from Amazon since I already planned to do so and thought this was a good time to do it. Obviously, I hope that the LAN cable won't have any problems, but I'm curious to know what the actual issue might be so here I am.
My PC: Lenovo Ideacentre 720-18ASU (yeah I bought it from a store), Windows 10 Home, Build 19043.
Network adapter: Realtek 8821AE Wireless LAN 802.11ac PCI-E NIC, updated to the latest driver (that's what Windows says, the driver is from 2018 tho).
Modem: It's an optical fiber modem called FASTGate that my ISP (Fastweb) gave me and it never had any problem. Still, it's italian tech crap. Don't expect too much.
If you need any other information let me know, I'm stupid and don't know exactly what might be useful or not.
What I tried:
First of all, let me tell how I know it happens every 30 seconds - I tested the ping to my modem's address on CMD prompt and every 29 pings, it pauses for a second, then starts again with a "Request timed out" or a "2000/3000ms" (then goes back to 1ms for the next 29 pings).

- Switching from 2.4GHz to 5GHz connection and viceversa (I do that all the time when I start lagging);
- Disconnecting and reconnecting to the wi-fi;
- Restarting the modem;
- Restarting the Desktop;
- Restarting them both at the same time;
- Disabling the Anti-Virus (Kaspersky);
- Resetting the network settings;
- Resetting the modem;
- Resetting them both at the same time;
- Resetting them both at the same time and waiting an hour before turning them on because I got angry;
- Disabling and enabling the Network adapter;
- Uninstalling and installing the said Network adapter;
- Uninstalling the IPv6 protocol thingy (I just read to do it somewhere and did it, I'd smash my monitor at this point if someone told me it could help);
- Testing the ping on my smartphone with some random app I found (no problem at all);
- Connecting pc to the same modem via hotspot on my smartphone (same issue);
- Connecting pc to 4g via hotspot on my smartphone (same issue, so I'm pretty sure it's the adapter's fault);
- Writing that magic formula in the CMD prompt (ipconfig /flush, /renew, netsh ip and all that stuff I don't remember right now);
- Restarting PC again because why not;
- Trying again the hotspot just in case.
- Calling my ISP - they would say to restart my modem, then since it's all fine for them, it's my problem and they can't do anything about it;
- Going deeper into changing the adapter's option, I didn't even try to change the DNS (I had a problem one year ago where my pc would disconnect after 5 minutes online until I restarted it. Nothing fixed it and it went on like this for 2 months until I changed my ISP lol. So now I get nausea just by thinking about network issues);
- Doing a backflip;
- Resetting my desktop (I really don't want to buy an HDD to backup and install every software again);
- Smashing the modem;
- Connecting with a LAN cable (I should have it by tomorrow);
- Connecting to another modem (if smartphone's 4g hotspot doesn't count);
- Go to sleep and wait.
- The problem started while the PC was already on and I was using it;
- Nothing similar happened in the last year with this modem;
- Just once, after the first modem reset, the "lag" did not happen for about a minute after starting the ping test on CMD prompt;
- Three or four times it disconnected after 50 pings, not 30;
- Other devices such as my smartphone do not have this same issue;
- I just think my adapter chose to die in the most annoying way possible;
- As you can see by what I wrote, I've been staring at the command prompt for 7 hours, I just spent another hour writing this, it's 6 in the morning and I need to sleep. I'm going crazy over this and sorry if I wrote something stupid or not useful. Please send help.
