My roommate and I recently installed WiFi in our apartment, but since the beginning 3 devices have consistently been able to connect and 2 have consistently not been able to connect.
-My Lenovo Thinkpad
-Roommate's HP 2000 Notebook PC
-Roommate's HP Compaq desktop
-My HP Pavillion laptop
-My Dell Precision desktop
All devices are running versions of Windows.
On the HP Pavillion laptop (Windows 7), when I enter the password to connect to Wifi, I just get the message, "Could not connect to [network name]." This message seems to pop up too quickly, as if the computer didn't really have to think before rejecting the attempt. It seems like it took even less time than when you simply enter a wrong WiFi password on any given computer, which leads me to think that the HP didn't really try to establish the connection.
On the Dell Precision desktop (Windows 10), the problem is stranger: I have apparently connected to the network, but I still have no internet access; so when I look at the network in the queue, it says "Secured, no internet."
Also, I repeat that the problem is consistent, not sporadic. All devices consistently either work or don't.
1. Signal strength: Definitely not--it is strong throughout the apartment.
2. Versions of Windows: Probably not. My non-connecting laptop and desktop are running different versions, and my connecting laptop is running the same version as the non-connecting desktop.
I did just a little bit of searching for similar problems. Here are some potential causes that I have found which may or may not have anything to do with my problem:
3. Modem channel needs to be changed.
4. Devices' security settings are blocking wireless signal
I apologize that I'm not totally sure what information would be useful, as I am a bit of a noob.
Any help is greatly appreciated.
