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.
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.
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.
Thank you so much I spent a day trying to get my new acer to connect to wifi convinced I was doing something wrong and I was just about to give up and take it back to the shop when I found your post it worked perfectly thank you so much - how do you figure these things out?? I'm so happy
I just tried this on my Acer V 15 nitro and so far so good, the only thing I'm noticing is that I no longer have access to 5G wifi. Which is a small price to pay to be able to stay connected, but do you know if there is another setting thats just as effective but also lets me use 5G?
I don t have a wireless mode optin in there, all I have is memory range and IRQ. my laptop won t connect to home wifi but it will connect to mobile hotspot, I have deleted and re installed my drivers several times and nothing. I check for updates but it says my driver is up to date.
Go to advanced tab, at the bottom you will see "wireless mode selection". click that and change the value on right side. It worked for me. Big thanks to Carl M5
When I open all network adapters, "Qualcom Atheros" is not present. How do I get it back? I reset the network adapters and all I get is the ethernet adapter. Wifi is gone.
I have a new acer aspire E1-522 that's has never been able to connect to wifi. It doesn't detect any networks although all of our other devices are able to connect. I have reset the entire system to factory but still not working.....help
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,
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
