Aspire E 15 cannot connect to wifi

My laptop suddenly cannot connect to WiFi (error "Unable to connect to this network").  I run the Acer care center, and it says that my system is up to date (including drivers).  I used the health check to identify the problem, but "Troubleshooting couldn't identify the problem.

The wireless network card is Qualcomm Aheros QCA9377. I went to http://www.acer.com/ac/en/US/content/drivers and there are 3 Atheros drivers listed.  I don't know if I should install a new driver and install since there are 3 of your choice.

Please advice.  Thank you.

I solved the problem by installing the driver Wireless LAN Driver (NFA435) (ver. 12.0.0.102), available at http://www.acer.com/ac/en/US/content/drivers#_ga=1.265780556.217261961.1453001145.

  • Aspire Z3-615 cannot connect to WIFI 5 GHz

    Hello everyone, I'm just curious. I currently have 2 lines wifi, a normal 2.4 and 5 GHz WIFI.

    However, my computer, the Z3-615 Aspire on windows 8, is not able to read the 5 GHz WIFI.

    My network card is atheros ar956x 5 GHz qualcomm.

    I was browsing around the forum and am sure that my adapter is a single channel, which I guess means he can't read 5 g :/

    My phones are able to connect, so I wonder if there is a way to ensure that the computer can read 5g?

    Thanks for the help :-)

    I don't know if the link below is your computer, but if this is the case, it says b, g, n, which means it lacks a 5 GHz radio.

  • E5 - 571 cannot connect to wifi at all

    I bought the Aspire E5-571 yesterday and I tried to connect to wifi with no luck what so ever. It is running windows 8.1 x64bit. I've updated the network adapter atheros a.285 provided on the acer driver downloads section. but still no luck. WiFi connections are displayed but I can't communicate with them, I have infinity of bt using the bt hub 4. I go as far as to type in the access code for the router but says that it cannot connect. my other devices can connect (iPhone, portable under win7). the only way to connect is to sit on my staircase using an ethernet cable. Thanks in advance for the help.

    I found a solution!

    running all the updates and not having anything work, made me think of getting a new network card. It is clear to see that the problem lies in the qualcomm atheros so after watching youtube videos, I thought that it would be difficult for everyone to open their laptop and reinstall the network adapter. siimply so quite, I use a plug usb adapter you can get on amazon/ebay/or a store with an it Department for a simple tenner. Although this has not resolved the problem with the qualcomm's atheros card, I am able to connect to wifi, so I am very happy. Thanks for the reply.

    Anyone have any ideas on how to fix the Acer One wifi to connect?

    I use my phone to take a picture, then blow up the images to read the tiny letters usually.

    I guess you have already forced the tablet to forget the network, rebooted and then retried connecting? It is sometimes difficult to get them to really forget a wrong entered password.

  • Somes devices cannot connect to WiFi TimeCapsule more

    Hi everyone, I am facing a weird situation.

    Current configuration: the home Wifi is provided by a TimeCapsule, which has its firmware updated. A couple of device (10) are regularly connected (printers, iMac, MacBook Air, iPhone, iPad, iPod, etc.). Nothing very complicated.

    The situation:

    This morning, I had 2 friends at home with their personal devices (one tablet of Nexus and an iPad 1st generation). I tried to connect to my Wifi and it never worked. On the iPad, the wheel turned in the parameter space WiFi and no internet connection was possible. No Wifi setting has been provided by the TimeCapsule (no IP, etc.). On the tablet of the Nexus, I got more details: he was blocked at the stage of IP address get.

    Obviously, my first thought was to restart my TimeCapsule. Unfortunately, nothing has changed: these new devices have been blocked at the same stage and... my daughter iPod also got stuck. Exactly like the iPod from my friend. But has been connecting iPod to my daughter to my wife for the last 3 years!

    My friends finally left, so the problem is "over", with the exception of the iPod of my daughter. Until this morning, he was perfectly able to connect as usual, but now no.: the wheel keeps turing in the Wifi configuration. I have obviously reset network settings: nothing has changed.

    On the TimeCapsule, I see that the iPod gets an IP address. Also, when I change the name of the iPod in the control area, I can launch a sync to iTunes on the iMac and the iPod name is updated! So, this means that the iPod IS connected via Wifi, but it is not possible to browse the Internet or connect to what. The WiFi icon does not even appear in the top bar.

    All other devices (iPad, iMac, etc) works perfectly.

    Any ideas?

    M.

    ... except for the iPod from my daughter. Until this morning, he was perfectly able to connect as usual, but now no.: the wheel keeps turing in the Wifi configuration. I have obviously reset network settings: nothing has changed.

    As you probably already know, reset the network settings deletes saved passwords and network configuration details. It also exports the residual caches and preferences. Most of the time, it should be fixed.

    As it didn't, the only other suggestions I could give are:

    • Go to the option "forget network Wi - Fi" in iOS settings and then manually try to join the wireless network yet.
    • If this does not resolve the problem, then possibly one or more of your Wi - Fi connection settings for your wireless network may have to be changed:
      • Make sure that the network name does not include spaces or special characters.
      • Don't 'hide' your Wi - Fi network.
      • Try temporarily disabling Wi - Fi security to see if the iPad will connect now.

  • Smartphones blackBerry 8320 cannot connect to wifi at home

    I recently got a BB8320. All right, I get emails and can send in public hotspots that I am able to connect to Wifi, download EDGE or sometimes UMA. But with my home network wireless, I have a connection problem. Searching for networks brings my router. I select Connect and enter the WPA key but I get an "impossible to associate with the network" error message. This could be to do with my ISP? (Tiscali, in the United Kingdom). Mobile operator is Orange. Any ideas, anyone?

    Got home last night, looked at the phone and guess what? Display of SSID wireless and also UMA! Phone has been turned off at night, so I guess I should have restarted after notice of the folling baseball. Thanks for this and hope it helps others :-)
