Dell Inspiron 13-7352 Wifi Dropped Cannot Connect!

I also wanted to return the laptop after talked to Dell's Technical support. They asked more then $100 to fix it or buy one year support for $250. Hopefully I got help from my son-in-low who is experienced licensed network engineer and we spent an hour or more on phone to fix the problem and find the correct Wi-Fi setup.

Here is the solution that works for my 2015  Inspiron 13 7000 2-in-1.

1. Go to Setting from Start button.

2.  On Setting window go to "Network & Internet"

3. On "Network & Internet" window open "Network and Sharing Center"

4. On Network and Sharing Center window find Connections: Wi-Fi (your wi-fi name)

5. Click on Wi-Fi and open Wi-Fi Status window.

6. On Wi-Fi Status window click Properties button and open Wi-Fi Properties window.

7. You will see the list of items for this connection.

8. Pay attention on two items: Internet Protocol Version 4 (TCP/IPv4) and  Internet Protocol Version 6 (TCP/IPv6). On my laptop both protocols were checked.

9. Uncheck TCP/IPv6. click OK and close other windows.

10. Restart the laptop.

After that my problem was fixed and I got Internet.

Hope it will help for some of you.

It may or may not be related but I had the exact same symptoms and I solved it by updating the Network Adapter Driver, which is tricky when your network adapter is disabled!

Here is how I solved it.

1.) Go to Device Manager (Either from the Control Panel or searching in the cortana search).

2.) Scroll down to Network Adapter. It should show the problematic adapter (Mine was Intel) with a yellow exclamation mark on it. Double click on it.

3.) Go to the Advanced Tab.

4.) Change the wireless mode from "Auto" or "a/b/g" to "b".

5.) Click "Ok" to save.

6.) Your adapter should appear and connect. If it doesn't, repeat above and try changing the wireless mode to "g".

7.) Once you are connected. Don't stop there. Go back to Device Manager and update your driver.

8.) Double click on your Wireless adapter, go to the driver tab, click on Update, and click on Search Automatically.

9.) Follow the prompts and VOILA!

(Figure 1. Error Message from Device Manager before following the steps above)

I received a model 7359 a couple of days ago and the wireless connection would not last more than a minute or two before it would be dropped and the wireless card could not be seen.

I went to the Dell support page, entered the service ID of the machine (7 digit code on the bottom) and looked at the available updates.  Under networking, there was this file, released 15-Dec-2015 (I think that was the date, but I might be off by a bit):

Network_Driver_RWMWW_WN32_18.30.0.9_A01.EXE

I recommend that you do the same procedure for your machine (probably will have to do it from another computer, as I did, and copy it to a USB stick) and see if there's a similar update.  In my case, it turned a piece of junk that I was very seriously considering returning into a functional laptop.

Good luck!
