Dell Inspiron 1521 Wi-Fi problem

Recently Windows 10 force updated me to the earlier creators build that came out this year (had Windows update service disabled so I wouldn't get updates) and the original Wi-Fi card wouldn't work. Found some driver that "worked" but the connection speed was under 100KB/S. Ethernet after the recent creators update works just fine though, when it was broken with the previous update.

I bought an Intel Dual Band Wireless-AC 7260 because it has Windows 10 drivers and I now get a weird problem.

Upon booting to the desktop I only see the Ethernet icon in the notification area of the taskbar and in device manager I see the two adapters

Broadcom 440x 10/100 Integrated Controller

Intel(R) Dual Band Wireless-AC 7260

Now if I disable and re-enable the Wi-Fi card I get the WI-FI icon in the notification area of the taskbar and I get the red X meaning no available networks. In device manager I get this.

Broadcom 440x 10/100 Integrated Controller

Intel(R) Dual Band Wireless-AC 7260

Microsoft Kernel Debug Network Adapter

Microsoft Wi-Fi Direct Virtual Adapter #2

RAS Async Adapter

Teredo Tunneling Pseudo-Interface

WAN Miniport (IKEv2)

WAN Miniport (IP)

WAN Miniport (IPv6)

WAN Miniport (L2TP)

WAN Miniport (Network Monitor)

WAN Miniport (PPPOE)

WAN Miniport (PPTP)

WAN Miniport (SSTP)

None of that ever appeared at any time before the earlier update which I only received maybe 3 weeks ago.

Also when I boot up if I go to the airplane mode setting page under wireless devices it says it couldn't find any, but if I disable then enable the WiFi card it shows up on the airplane mode page.

If I run network troubleshooter I get the WiFi icon with an asterisk and if I put the cursor over it the pop-up says connection are available but if I click on the WiFi icon it says no WiFi networks found.

When I do manage to get a list of connections I try to connect to mine and when it tries I see the device manager act like I did a manual scan for hardware changes which it does 2-3 times then the Wi-Fi shows the red X and I can let the laptop sit there and it will still keep trying to connect to my network and doesn't seem to time out or anything.

That just about covers all the issues I think.

Any idea what the problem could be or if it is just a bad update Windows pushed out?

I did read online where a lot have had problems with this card and the previous creators update which was supposedly fixed in the most recent update. They also gave some fixes which sadly didn't work for me.

Thank you for your message.


This system is not tested for Windows 10 & there are no official drivers available for this model. There are only Windows XP & Vista drivers available.


There will be driver conflictions, this is the reason you have this issue.


The wireless card has drivers compatible with Windows 7 & Windows 8. You can try to install these drivers in compatibility mode & check if that works.

Interestingly enough Windows 10 runs great on this laptop only having to use an older display driver so the screen turns off when the lid is closed.

That particular card does have Windows 10 drivers available from the manufacturer.

The issue from what I have read about others with similar problems is that the problem cropped up after the earlier creators update this year and that the newest drivers don't seem to work, but the Windows 8 version did work. With the newer drivers the card in device manage has a problem  but with the Windows 8 drivers the card shows as being fine in device manager.
