Unable to connect to internet in Win10

Hi thai,

Not sure if your problem is connected, but the recent update has caused different problems with different users and some have reported that the update messed up their internet connection.

First I would check the update history and if the timing of the update matches when the problem occurred, then I would suspect the update. If so, then a reset to a restore point before the update could undo the problem.

If the above timing doesn't match out, then use the network trouble shooter (built into Windows) to help determine the problem. To use the network trouble shooter in Win 10: Enter in the Ask me anything box Network and select Network and Sharing Center. When it opens select Trubleshoot problems. If it can fix the problem it will. If not, post back what it said.

Hi thai,

Since the other two devices can access the Internet, then its not the access point but the adapter. The adapter built into Acer. I suspect that the adapter drivers have become corrupt. See if you can download the most recent driver for this adapter. Usually these drivers are available from the maker's web site (Acer). Download to a flash drive with one of the other working devices and install the driver to the Acer through the flash drive.

Let me know how it goes.

Hi thai,

This site may have what you need. Scroll down to Network and Wireless adapters. Select the driver for your adapter. You'll notice that the driver works for Windows 10, 8 & 7 for both 32 and 64 bit systems.

Hi thai,

The verification code is the same numbers to the left of the box. This is to make sure a human is downloading and not a link from another web site. The download opens the Explorer window of where to save the download. Just Browse to the flash drive to download the file to. It will be a zip file which will have to be unzipped to get the driver file. Driver files are .inf files and some can be .exe files (that contain drivers and software). Alternatively, the Acer website offers the driver too at this web page:

Acer Drivers and Manuals

Since the Acer can't access the Internet you have to download the driver to the flash drive. Plug the flash drive on one of the other devices with Internet access to download the file. Move the flash drive to the Acer. If needed unzip the download to extract the .inf driver file. Now go into Device Manager and select the adapter and select Update driver. Select that you have the driver file and Browse to the driver file on the flash drive to have it updated or replace the driver that you have now.

Notice that the same driver for this adapter works for many different versions of Windows so the driver most likely will be the same driver that was originally installed (which has become corrupt).

I gave you the other site rather than the official Acer site because the first site does downloads and the Acer site seems to want to directly install the driver to your Acer device which you can't because it won't connect to the Internet. If the Acer site will allow a download then download from them. Make sure you get the correct model number of your Acer when choosing the driver to download.

Let me know if you need further help.
