Dell Inspiron 15 3537 Issue

Hi Experts,

I had a customer's Inspiron 15 3537 laptop in my possession last week with a wireless adapter and LAN adapter issue the wired LAN was not appearing in device manager and the wireless had an exclamation mark next to it.

I downloaded from the Dell site all the latest drivers as I noticed there was an issue with the USB and Graphics as well.

I have fixed them (USB & Graphics) but attempting to install the only LAN driver available on the Dell website I get the message that the "Lan adapter is not present and cannot install...

I was however able to reinstall the wireless driver as it had an issue saying the airplane driver was not installed (bit weird)

With the wireless driver reinstalled and picking up that the driver is present and correct but not being able to see any available networks it was saying that it was now available but not turned on, which everytime I used the "F" key to do so it would only turn airplane mode on & off!!! there is no hard wireless switch on the laptop.

For now I have the customer working off a thumb size wireless adapter stuck in a usb port but at least it works but would like to resolve if possible... I can order a onboard wireless adapter replacement and try that I guess, but  wondering if the real issue maybe the MOBO?

any suggestions appreciated thanks in advance..

If the LAN driver doesn't show up in device manager like you say, then the NIC either doesn't exist at all, it is physically broken, or disabled in the BIOS. Otherwise you should at least see an unknown device or device with problems in device manager. Many BIOS allow you to disable the NIC so it isn't seen by the OS, so check that.

Any recent machine I have seen including laptops embeds the LAN card on the motherboard. The wireless card is usually a separate PCI card and replaceable.

So LAN card missing is almost certainly a motherboard issue.

The wireless card also appears defective.

The laptop looks like it might be 2 yeas old. Is that accurate?  It is questionable whether replacing the motherboard out of warranty is economically viable.

Thanks for your input John & Rindi....

Yes I believe it is older than two years John and out of warranty... I certainly wouldn't recommend to the customer in replacing the MOBO either!

but the customer quite like's this laptop and wants to keep it for now...

Rindi - The nic was working about a week ago, I will check the bios when I pop in thanks hadn't thought of that will post back after I have checked.

I do not get attached to laptops. True, I buy what I like, and my commercial units tend to last 5 years or beyond. But when it is time for new, I adapt to what is new.

Out of warranty means it is time now for the customer to move on.

There are four generations of Inspiron 15 3537 in the field each with a different WiFi card
(You can look in Device Manager for a Hardware ID or even take the keyboard off to see which you have):

Dell Wireless 1703 802.11b/g/n combined Bluetooth 4.0 + HS Driver (Foxconn)

Dell Wireless 1901 WiFi + Bluetooth Driver(Atheros)

Qualcomm Atheros AR956x series WLAN Controller

Dell Wireless-N 7260 (Intel)

Sounds like you already have the correct chipset and QuickSet drivers.

WAN is consistently controlled by Realtek LAN RTL8106E on the NIC

(Assuming 64bit Win8.x)
