Windows 10 Wi-Fi Networking not working intermittently

Question

Hi,

I have a laptop of Acer Brand (Acer Aspire V3 - 575 VT). It is an 64 bit, i7 CPU laptop with 16 GB RAM and 1 TB Hard Drive. My system is fully updated.

I use it both at Office as well as Home. At home as well as Office, we have an Airtel Broandband Connection with a Broadband Router which provides both Wireless and Wired access to Internet. At both Office as well as home, I connect to internet wirelessly through these two modems.

I am facing a strange problem for last one year. After every few days, my laptop just cannot find the network either at office or at home. It can discover all other networks around it (all neighbourhood networks) but either it will not find office network or home network or both. However, it always finds my mobile phone hot spot without any problem - never falters over there. And strangely, after a few days, it again re-discovers Office or home network (wherever it had a problem). I am yet to find a logical explanation. I have done everything I knew - like enabling / disabling network card, re-initializing TCP/IP stack everything - however no solution till now in sight.

I would greatly appreciate it if you could let me know any resolution.

Many Many Thanks,

Manoj

Hello Gloria,

I am afraid the situation has gone from bad to worse.

Now everytime i hibernate / shut down my laptop and restart it later, my Wireless lan card disappers.

I go into "Computer Management" admin console and it is not listed their as a hardware. I try to detect any new hardware, it doesn't work.

Ultimately, I have to do "Network Reset" again and reboot my laptop to get it detected again.

It happened again today morning. After resetting it, I looked into events related Lan card and noticed following Warning:

@Manoj Kumar Hi,

Thank you for posting in Q&A!

I'm so sorry to hear that. But usually "network reset" is an official and common suggested method to fix network problems, which wouldn't cause some problems theoretically.

Based on your description, it seems that your system fails to detect the wireless NIC, there might be some problem with your system or wireless NIC. As you mentioned before, you disabled and enabled your NIC, have you ever tried to reinstall and update your NIC?

If that still doesn't work, it is suggest that you can backup your important documents and reinstll the system.

Hope you have a nice day : )
Gloria

Hi Gloria,

The only update is that I am back to square one... I am back where I began. My laptop is able to find networks both at home as well as office, but only to lose it after 2-3 days....

I have now decided to replace this laptop.

Thanks,
Manoj
