Wifi Adapter missing

[sreekanthu]

Hi,

Please note i have an Acer Aspire E5-574G Windows 10 laptop. The notebook is just more than 8 months old. I just noticed that i am unable to connect to a WiFi network. I tried going to network sharing and adapter options, and the wireless adapter itself is missing. Is my WiFi adapter dead?. If it is, how much would it cost for replacement?.

Try on a different WiFi network. If you still can't get connected then I would try connecting via Ethernet.

In the end, you will probably need a new WiFi card. You then have the option of replacing the internal one or getting an external one, that connects via USB.

This is far from "Best solution", @ErAnkurPaul. In fact, who said it's even a solution? Not OP. Who's monitoring this? Replacing hardware without testing is NO SOLUTION.

Terrible advice without further troubleshooting. Something about the Intel drivers could be amiss. Shut down, power off [Is this truly necessary? Why not; it may be hardware related], and restart?

Go to Control Panel > System > Device Manager and look under Network Adapters.

Is your adapter listed?

* If so, right-click it and click Properties. Does the Device status box say "This device is working properly". That speaks for itself. Repeat for anything whose name resembles that of your adapter (like "Intel WiFi adapter....").

* If NOT, look for its name as its own entry in the list. If not there either, maybe you DO have bad adapter. Maybe.

At this very time, I'm using the internet successfully, wirelessly, despite the message "No supported Intel Wireless adapter is found." Fifteen minutes ago, it was there, but Disabled and refusing to let me Enable it. Other days, it's Disabled but lets me Enable it. Meantime, I'd done nothing. Crazy. I don't really know what might be missing or wrong. Bugs in Intel software, no doubt. But no updates available. Maybe Dell's problem.

I only need it to be Enabled today to try to link my wireless earbuds to the computer. Whatever. Using my phone.

Just don't run out and get a new wireless adapter just yet.

I criticized the "Best Solution" a few days ago. Those comments still hold.

New thoughts:


Replacing the adapter isn't always necessary. The message doesn't say the adapter is defective. Something is keeping it from being recognized, though. (I've been told WiFi adapter wasn't found WHILE I WAS USING THE INTERNET THROUGH A PUBLIC WI-FI connection. I only found the message [for the 100th time] when trying to link my wireless phone to the laptop.]

Intel or Dell (my brands) has some problem that's lasted at least six years by my count.

Usually the problem soon goes away without me having done anything except opening and closing Properties and such, Friday, the message persisted.

So I nosed around everywhere I could think of and found nothing promising, as did Windows troubleshooter.

So nosing again, I stumbled onto Intel Centrino Wireless-N 1030 Properties > Advanced and checked how the values were set.

I set Bluetooth AMP to ENABLED (AMP stands for Alternate MAC/PHY and uses the 802.11(Wi-Fi) as the high-speed transport. If disabled, Bluetooth HS is turned off). After I clicked OK, problem disappeared immediately.

It doesn't seem like that should have done anything, but given a bug elsewhere, who knows how the settings interact.

So, MY problem: *FIXED* by toggling a setting. Will it return? Probably. Not yet, though.

=========================================

While I was in there and reading anyway, I set Roaming Aggressiveness to LOWEST:

"Use default value to balance between not roaming and performance.

"Lowest: Your wireless client won't roam. Only significant link quality degradation causes it to roam to another access point."

I noticed my Ad Hoc QoS Mode was set to WWM ENABLED, which isn't the default, so I disabled it.

"The Quality of Service (QoS) control in ad-hoc networks prioritizes traffic from the access point over a Wi-Fi Local Area Network (LAN) based on traffic classification. WMM* (Wi-Fi Multimedia*) is the QoS certification of te Wi-Fi Alliance* (WFA). When WMM is enabled, the adapter uses WMM to support priority tagging and queuing capabilities for Wi-Fi networks."

Still no problem today.
