Hi,

 

I have been experiencing limited wifi connection issues to my network from my laptop, even when I tried safe mode with networking.

To clarify, I have two laptops. One, an HP pavilion running Windows 7, which I am able to connect to my network from with no issues, so it isn’t the router. The other is an Acer Aspire V3-7772G, which runs Windows 8.1 which is only 4 months old which originally I had no problem connecting to the internet wirelessly to begin with. I can’t fathom whether I have a faulty network card, despite the laptop being relatively new. Normally I check it with safe mode to identify if it’s a faulty driver first or not; but that was after I went through all the troubleshooting methods available as follows:

  • Checked that airplane mode was turned off and wireless communication was turned on.
  • Made sure the network adapter was enabled
  • Checked powersaving plan, ensuring maximum performance for ‘On battery’ and ‘Plugged in’ under balanced plan
  • Ran troubleshooting, resetting network adapter
  • Ran network troubleshooter, clicking identify and repair network problems.
  • Ran Avast and Malwarebytes Anti-malware, both premium versions, and no malware or viruses were affecting my laptop.
  • Updated my network drivers:

My network driver is Qualcomm atheros ar5bwb222 and the current driver that was installed was version 10.0.0.264 for my Acer Aspire V3-772G. So I updated the driver finding one which was version 10.0.0.276 for my laptop. Anyways, after running the exe setup for the 10.0.0.276 driver and installing, I rebooted, flushed the DNS but it remained as limited connectivity. Then I tried an older version than the one that was preinstalled, a 10.0.0.255 version, rebooting and flushing DNS as before, but once again, it remained the same

  • Reset the TCP/IP stack and rebooted
  • Reset TCP/IP Autotuning and rebooted
  • Made sure I had disabled sleep mode (Wake up Wi-fi adapter)
  • I then decided to reset the PC back to its original factory setting since I did not have a lot on it, yet the internet connection was still saying limited. It still says problem with wireless adapter to access point.
  • Then as a check, I tried connecting from safe mode with networking and it still remained limited connectivity, unable to connect. Thus, I don’t know whether it’s corrupted or incompatible drivers, or a hardware issue, such as my network card.

I think I have tried every method available to me. I would appreciate kindly any assistance regarding my problem.

Hello there,

 

Did you use "Windows update" to automatically get recommended drivers and updates?

Hi, thank you for your prompt reply. If you mean since I reset it to the original factory settings, no I haven't to be honest. I think when the problem occured before I went through all the messages mentioned, may have been because of a windows update possibly. Should I do so now anyway?

Being that it worked and then stopped. Doing a factory reset and the same issue happening even using different drivers and Microsoft Update, I would call Acer and RMA the computer before trying anything in the links I posted below.

 

There have been other people with this same issue. Is your model the 772G and not 7772G as in your post title?

 

From things I have read, Windows 8.1 can be driver hell. This article is from a year ago but it gives you an idea about what I mean.

 

See if doing any of the steps listed here helps. I know you reset TCP/IP but there are other setting that can be changed.

Hi JohnC

 

That was an error. Yes, my model is 772G not 7772G as originally posted. I have heard about how Windows 8.1 drivers can be hell. Nonetheless I will go through the steps from the link first and post my reply.

Hi,

 

It appears the problem is my router's firmware needed to be updated. I spoke with my ISP and after explaining that my windows 8.1 laptop was having limited connection issues they explained I probably needed to update my router for compatibility. After linking me to the latest firmware and what I needed to do, my network adapter is now wirelessly communicating again.

 

Much obliged to you guys for any assistance and recommendations on here.
