Wireless network adapter disappearing?

Hi, I've had an Asus Q400A for about 4 years now. A few months ago, it started doing this thing where I'll be working online, and suddenly I'll lose wifi connection. Then the wifi bars at the bottom of the screen have a yellow exclamation mark on
them, and then a few seconds later it turns into the Ethernet sign with a red x on it. My wireless adapter disappears completely. If I go to my device manager, all that is listed under my network adapters is the "Qualcomm Atheros AR8151 PCI-E Gigabit Ethernet
Controller (NDIS 6.30)." I am missing my "Intell Centrino Wireless-N 2230" wireless network adapter. It's like my computer's wifi is completely disabled, and I am only able to connect to the internet via Ethernet. Sometimes I am able to fix it with the troubleshooter
before the adapter shuts off completely and disappears, as it always turns yellow with the exclamation mark for a few seconds before disappearing. If I am fast enough I can run the troubleshooter and it will reset the wireless network adapter before it disappears.
But when this doesn't work or I am too late, not even restarting or shutting down my computer will bring it back. It just kind of comes back on its own after I let my computer sit turned off for a few hours. This is INCREDIBLY annoying, as I am a busy high
school senior, and most of my school work and internship work is done on my computer. I have tried reinstalling the intell wireless adapter driver, and that did not work. What should I do? Is this a hardware problem? I have an Asus Q400A notebook running Windows
10. I have also tried turning off the option for the computer to turn off the adapter to save battery and that did not work.

 

USB Wireless adapter not connecting to Wifi

Hello

I am having trouble making my new USB Wifi Adapter to work. The drivers are working fine but the issue is it is not connecting to wifi.

1. I am using Windows 10
2. The adapter which I am trying to work is Alfa AWUS036NHA 150Mbps
3. I have also one USB mini wifi adapter attached to my other USB through which I am currently using internet

From the above screenshot, the Wi-Fi 2 is which I am trying to connect. When I right-click on Wi-Fi 2 and click on Connect/Disconnect, It shows the already connected Wifi through USB mini adapter.

When I Disable WiFi and try to connect through WiFi 2 then it shows an error "Change settings, such as making a connection metered"

The device utility does not show any Wifi available connections though there are 2-3 wifi connection is there.








any idea how can I make connect to internet using my new Alfa AWUS036NHA 150Mbps Wireless USB Adaptor - Wi Fi 2 on Windows 10 ?

 

Wifi Network Adapter disappearing Win10

I'm having wifi problems but I can't figure-out whether it is hardware or software. There is evidence that recent versions of Windows 10 have been causing wifi problems. If the problem is with Windows and they are going to fix it, then I can stop worrying about trying to fix the hardware (I am travelling abroad and it is near-impossible to find expertise/parts/tools).

Gory Details:

System: Levono Yoga2 Pro laptop. Intel Core i7-4500U. 8GB RAM. Windows 10 64 bit.

I have been using Windows 10 since it came out without any problems. I have been keeping it updated.

Precursor to this problem: On 4th November 2016, mid-session, apropos of nothing, my wifi stopped seeing the wifi network it was connected to; or any other wifi networks. (My phone could see plenty). This was evidenced in the Taskbar, Action centre, Settings dialogs of the PC. The Windows version was upto date at the time, but downloading the next week's Microsoft Patch Tuesday updates (9th Nov) fixed the problem. System working AOK. Yay.

(MS update: KB3200970 "Addressed issue with the system tray showing no Wi-Fi connection even when Wi-Fi is present")

System fixed - I made a system-restore point.

The "fix" held for 24 hours, then a new, more severe problem started occurring (='the current problem').

Current problem: After 3 to 5 hours of normal, troublefree operation, the PC stops seeing the wifi entirely. Any menu options associated with wifi networking disappear entirely. The Device Manager can no longer see the Network Adapter (Intel Wireless-N 7260) or its driver software. (That statement is somewhat summmarised - see Note 1 at the bottom of this post for more details).

I can't see any Events in Event Viewer which would explain the disappearing Network Adapter.

If I do a (whole) system restore back to my restore point, then everything is fine for a few hours, then the Network Adapter disappears again, along with any chance of seeing any wifi controls.

System Restore consistently fixes it for a few hours. Then the Network (adapter) consistently disappears again.

So, is that hardware or software?

One might think it is temperture/overheating related, but the problem also once occurred overnight when the PC was switched off (it was fine when I went to bed and switched it off, but was 'broken' when I switched it on again in the morning).

One might think it is Virus related, but everything shows-up clean in MBAM and Avast.

If it is a hardware problem, why would a system restore (to a point a few days ago) fix it?

I'm thinking/hoping that the problem is caused by recent versions of Windows 10 (f,g below). But I can't find examples of other people suffering.

If it is caused by the OS, how does one inform Microsoft about it? (I don't want to join the 'Insiders Community')

Any ideas?

TIA

p.s. I have done as much diagnostics as possible - gory details here:

Note: the text "Result: FAIL" means that after a few hours of normal operation, AOK, the Intel Wireless-N 7260 Network Adapter can suddenly not be detected and any wifi activity/option becomes unavailable. Restart doesn't help. Restoring the system to a previous state fixes the problem (for a few hours).

Scenarios a-e all have the wifi switched on and connected to a wifi network.
a) System status up-to-date at 10 Nov. Result: FAIL

b) System status reverted to a Restore Point made in OCTOBER 2016: Result: FAIL

c) System status up-to-date at 10 Nov. Updated Network Adapter DRIVER to a newer version found by Device Manager (but not listed in the manufacturer's website's list of drivers). Result: FAIL

d) System status reverted to a Restore Point made in AUGUST. Retained old NA driver. Downloaded and applied November 9th MS Updates and updated Browser (Firefox) Version and Virus definitions: Result: FAIL

e) System status reverted to a Restore Point made in August. Retained old NA driver. Update Browser (Firefox) Version and Virus definitions, but DID NOT download/apply November 9th MS Update: Result: RUNS FINE FOR THE 4 HOURS UNTIL MS FORCES THE LATEST MS OS UPDATES TO BE APPLIED, then runs OK for a few hours then FAILs.

.

Scenarios f-g have the wifi switched OFF; or switched on but not connected to a wifi network; so that Automatic Updates can't be forced onto the computer.

f) System status reverted to a Restore Point made in August. Wifi switched OFF. Result: RUNS FINE FOR THE 14 hours I tested it. (i.e. the Network Adapter appears to be fine, as reported by the Device Manager)

...

g) (follows on from (f))... Wifi now switched ON but options set to "forget" known wifi networks, (so wifi is ON and polling nearby networks, but is not connected to any of them). Result: RUNS FINE FOR THE 6 hours I have (so far) tested it. (i.e. the Network Adapter appears to be fine as reported by the Device Manager)

Conclusion: f and g seem to suggest that the problem arises from later (current) versions of Windows 10. But this is inconclusive, because in scenario (f), the wifi card is not being used and and (g) it isn't being used for sending/receiving internet traffic

(N.B. I am abroad and using my hotel's wifi network(s) to try and use the internet. I have no control over the network itself).

Note 1:

When I say "The device manager can no longer see the Network Adapter" - this is a summary of what happens - infact, it seems to go through 4 separate stages:

1) normal operation - everything AOK.
2) The PC reports it is still seeing the wifi connnection that it is/was connected to, but is seeing no other wifi networks. The wifi network it connected to can no longer send/receive any data
3) The Device Manager shows a yellow warning triangle on Network adapters> Intel Wireless-N 7260, and 'Properties' shows "No drivers are installed for this device."
4a) The Device Manager shows a yellow warning triangle on Network adapters> Intel Wireless-N 7260 and Properties shows "This device cannot start. (Code 10). This device does not exist."
or
4b) Device Manager, Network adapters> doesn't show Intel Wireless-N 7260 at all.

A few minutes pass between each step through the stages occurring. Other apps running on the PC (e.g. mp3 player) freeze up for a couple of seconds when each stage changes to the next.

edit:
just found these in the event log immmediately before the latest fail

6 of these:

followed by two of these:
