I have a Dell Inspiron 15 3000 laptop for which I had to replace the hard drive back around April. Immediately after, I was having difficulty connecting to the internet. It would make a wi-fi connection, but would not recognize the internet. (I knew the internet was up as my other laptop and my TV connected fine.) It did this sporadically for a while, then the problem seemed to go away.
Last night, my ISP went down and when it came back up, the problem was back. Wi-fi connection was okay, but I had a hard time getting it to connect to the internet. It finally did, then this afternoon, it pulled the same thing again. As I am typing this on my Dell, it obviously finally connected. But does anyone have any idea what is causing this?
As I said, it is not my ISP, as my second laptop and my TV work just fine.
Is your modem also a wireless access point OR do you use a wireless router?
Do you have a USB wifi stick you could use to bypass the laptop wifi? Maybe you have a bad wifi HW in the laptop?
I assume all the drivers are installed.
Can you access your laptop from the other laptop sharing folders or even remote desktop?
for diagnosing stuff like this i usually boot up a gnu/linux live-usb to determine if its an real hardware problem or some random microsoft windows glitch.
I had a similar problem with my new HP laptop with windows 10. My old laptop with windows 7 had no problem connecting to the internet. Both were using Comcast internet via a wifi modem/router box to Comcast. TV worked fine.
After several days of using the HP help feature on the laptop to troubleshoot and connect to the internet - it told me to unplug the Comcast power cord from the wall, wait a few minutes and then reboot the entire system. Took 5 minutes for the TV to reboot. After that both laptops had no problems using the wifi connection and have had no problems since.
Not sure why a total system reboot solved the problem I was having with just my one laptop - but it fixed the problem.

Yep. I forgot to mention this. Thing is, this seems to solve "all or nothing" problems....he seems to be getting intermittent problems but yes, completely shutting down and letting the modems, routers, and wireless interface cards have a fresh handshake is a good idea.

Yes. I've rebooted the system....many times. That doesn't appear to be the issue.
