Hello.

I have been having problems recently with my Acer Aspire E 15. Since my sister brought my laptop to a friend's house, my laptop won't connect to our home wifi. I have tried a lot from resetting the router to resetting the wireless adapter and basically all that I can see on google. Whenever I try to connect to our home wifi, it always says "Unidentified Network. No internet access" even though the wifi symbol has excellent signal connection. I am contemplating on bringing my laptop to the store since it is still under warranty but I can't because I need my laptop for school.

Also, when I first tried restarting my laptop the internet worked. But now it never connects. I am just connecting my phone to my laptop and am using USB tethering to connect to the internet since all our other laptops and phones can connect to the wifi.
Any help is very much appreciated. I am very very frustrated already.

Thank you so much.

I bought an Aspire E5-575 and had the same problem. It's the first time I bought ACER so, I had no idea in what I was getting into.
I tried to work the problem out with the ACER online chat help. Don't waste your time.
Then I went to the source of all contemporary knowledge: the Internet, which to begin with showed me this has been a common problem for ACER for a very long time. I was already regretting the purchase with all my guts and after reading multiple treads about this, I did what finally worked for me. Here it is:

Go to "Device Manager" and click in the little arrow to the left of "Network Adapters" to open all the devices.
Right Click on "Qualcomm Atheros" and click in "Properties"
Click on the "Resources" tab and click on "Wireless Mode"
Change "Value" to "01-11b" (it was set in "12-11a/b/g/n/ab")
Click "ok" and make sure you are connected to your wifi network.

That's it. That worked for me although, to be honest, I don't know what I did so, if somebody think this was a bad idea for any reason, let me know.
Otherwise, enjoy your wifi.

Worked Fine, when I changed the value from 7 to 11.

Glad it worked for you.

I would like to add that, when I took the laptop to another setting, the problem of connecting to the wifi was back. This time, I did the same, but set the value back to 12 and it worked.

My conclusion (rather, my guess) out of these different results is that this has got something to do with the technology of the router that is being used. More recent technology seems to work with higher wireless mode values.

If anyone can confirm/negate this hunch (I know literally nothing about wifi tech) would be highly appreciated.

Hello,

Try this 1

1) Click on start --> In search bar, type ncpa.cpl and press Enter.

"Network Connections" will be opened.

2) Right-click on your "Wireless Network Adapter" --> Properties -->

Select "Internet Protocol Version(TCP/IPv4) --> Click on "Properties"

button --> Make sure "Obtain an IP address automatically" is selected

--> Click on OK --> OK.

3) If the problem still exists then check your SSID and the wireless password.

Good Luck

Hi! Thank you so much for answering. Unfortunately, I've already done those things and it still doesn't work. However, I do remember after troubleshooting the wifi that a message popped up and it said that the "Wi-Fi doesn't have a valid IP configuration". Can you please explain that? Thank you so much.

Hello,
Let us know your router brand name and model number. Do you have any other laptop connected to the WiFi?
Good Luck

Hello,
Try this 1
Go to your working laptop --> Click on Start --> In search box, type cmd --> Then "CMD" will be displayed in the search --> Now right-click on "CMD" ---> Select "Run as administrator". Now enter the below command
ipconfig /all > d:\ip.txt
Note: If D-drive doesn't exist in your laptop then change the letter d to c.
Now go to your D-drive --> There will be a notepad file with named "ip" --> Upload that file and paste the download url here.
Good Luck
