tl;dr New internal wifi adapter can't connect to home network, but it can to any other
I have this Dell Inspiron 15r 5537 which came originally with a Qualcomm wifi adapter. I left the notebook turned off for about five days last week, out of the power socket/outlet, and comming back to home, the notebook wouldn't turn on anymore (this note has a previous history of problems with power management that includes the battery being short circuited several months ago, rendering it a desktop/home device only and also had a very annoying process so it could get started and couldnt be resumed from sleep or hibernate anymore)
Well, I left it at the shop so this guy would find out what and fix it. He tells me he discovered that the previous wifi adapter (Qualcomm) was with a bad connection at the board, causing fluctuations on the current as it tried to turn on, which in turn wouldn't let the processor cooler fan spin properly or at all, and so it wouldn't turn on.
This explained why before this the notebook had the annoying problem of sometimes get beeping at turning it on, so I would have to force it shut and turn it on again and then it would boot properly.
So this guy replace the wifi adapter with a Realtek RTL 8191SE (which does not show on realtek's website) and the notebook turns on again with no problem and never beeping anymore. I test the notebook at his shop, and there it was connected to the shop's wifi network.
I get home and at first try Windows 10 says it "Can't connect to this network" every time I attempt to connect to the home network. Which is weird, since nothing was changed on router and every other device still connects to it.
So I put my cellphone to share it's 4G network via internet sharing through wifi. The notebook connects to it flawlessly.
Since it was late afternoon on a friday, I couldn't get back to the technician who "fixed it" and so I spent the weekend tweaking settings, unninstalling and reinstalling the adapter's driver (which is only the microsoft generic one provided by the system and can't find any other 'official' one) and what not.
I tried reseting router, changing SSID name, changing password, removing security password, allocated specific IP address to the new wifi adapter MAC adress. No success. Did not tried to reconfigure the router since I don't have the ISP password to reconfigure it.
I tried pushing the WPS button on router: Windows 10 states it "Can't get router settings. Insert password"
I tried ipconfig /release and /renew which states it can't release wifi's IP since the media is disconnected.
I can't "forget" the home network since it's not on the known networks list. MAnually connecting to the network doesn't help either.
I unchecked the IPv6 protocol.
I check with the internet technical assistant over the phone. We tried to specify a DNS server and do some pings, but to no avail since obviously it was not connected to the router (cable disconnected as per instructions)
The thing is that while trying to connect to the home network, the adapter icon flicks to disabled mid-throug trying to connect. After typing the password and connecting, it goes "wifi available -> wifi disabled -> ethernet disabled -> wifi problem -> wifi available" icons, and then it states "Can't connect to this network".
Can't confirm if this icon-cycle happens on connecting to other networks.
Also, with Device Manager opened, it simultaneously refresh the list of hardware devices as the wifi/internet icons flicks.
Well, back at this guy's shop, I explained what happened. Again, the notebook gets connected to the shop's wifi. Back home, "can't connect to this network". I test an external usb wifi anthena and that works. The ethernet port (which wasn't replaced) still conects through cable.
So
tl;dr again: new internal realtek rtl8191SE wifi adapter can't connect specifically to home's network while connecting to any other.
Please help.
