Hello, sorry for the long message but I wanted to give as much detail as possible.
Short version: Lenovo laptop with Windows 8.1 says wifi is connected and that there should be an internet connection but every +/- 15 min the internet stops working till I use troubleshooter or turn it off/on again manually. After that or even long before trouble shooter comes to a conclusion, the internet works again. Problem happens at my student house wifi and parents house wifi, both from the same company. My mobile phone can use the same wifi without a problem at all times. My network adapter is: Intel Wireless-N 2230.
Tried all the solutions I could find but to no avail. It still happaned in safe mode (update: found out later there was an issue with my provider around the same time so it might still work properly in safe mode). Last thing I tried was uninstalled Lenovo Energy Management yesterday night and afterwards my internet worked for the entire evening till today, around 9 PM. Now my connection drops again about every 15 min.
Update: around 10 PM the internet started working again. I did nothing during this time period except continue to use Chrome when it worked and run windows troubleshooter which only said the usual "it's the router" thing. It didn't show it diagnosed or fixed anything. I didn't restart my laptop or opened/closed any other programs either so I don't know what caused the sudden disconnections or fixed them. There was no official reported issue from my provider around that time either.
The windows troubleshooter said Windows can't communicate with the device or the resource (primary DNS server) and in the past 2 days the message changes, now it keeps saying there's a problem with the router but that can't be it, I called our privoder and they checked and told me it's working fine. My parents and brother use the internet without issues, they use Windows 7 and 10.
I tried the solution in this video but it didn't work: youtube.com QcWCmLsORMo
I pulled the router/modem out for 10 seconds but that didn't do anything.
I tried this; https://www.kapilarya.com/your-comp...ource-dns-server-is-not-responding-windows-10 But my command gave me an error when trying the 4th thing so i tried this; http://www.kapilarya.com/windows-so...-required-for-network-connectivity-is-missing
I tried the winsock reset thing and after I restarted my laptop things were a bit better, it only happens about every hour instead of multiple times now buw now it still happens every 15 min)
The ipcondig flush doesn't work, tried multiple times
Open DNS/Google DNS also don't fix it
I've also tried to reset things in the command screen multiple times but that also doesn't seem to work
The drivers are also updated, from both my laptop and from Intel automatic updater and I've tried setting it back as well which doesn't make a difference
I've disabled bluetooth and all other network adapters including the hidden ones except my main one
IPv6 was disabled for a bit but that doesn't solve anything
I've forgotten the network and reconnected with the password
I've tried pinging google and other sites but that's going fine -as long as I'm connected- with no package loss. Sometimes a timeout request but it works after that
I've tried the safe mode and the internet drop still happened (update: just discovered that my provider had internet issues around the same time I tried safe mode so it might actually function properly in safe mode)
Malwarebytes ran a scan and found some stuff which I deleted and restarted the laptop but nothing changed
I've tried turning off my smart or slim firewall from Norton but it still happened. Chrome has full access and I have no other antivirus program
I've unchecked all the boxes in the LAN settings
I've downloaded all the important/priority windows updates
I've tried switching from Chrome to Firefox but internet won't work there if it's not working in Chrome either
I've deleted my cookies/caches from Chrome
The "let the laptop cut this performance off when on low power" or something was never turned on in my laptop settings
I just saw my cursor move a little about 30 minutes ago without me touching the touchpad or the mouse I have plugged in now. Also a website refreshed out of the blue without me doing anything.
Also, idk if it's realted but my touchpad hasn't worked 100% when I tried installing a driver update from the Intel update thing, my laptop kinda froze but the program still worked and asked me to restart. I did and since then it has been feeling kinda "heave" so I had to turn on the sensitivity all the way up otherwise I can barely make it move.
That's all I can think of on the top of my head. Please if someone knows what I should do I'm getting really desperate.
