Aspire 771G V3 - no network via Wifi

Dear Acer community and support,

I use an Acer Aspire V3 771 G model computer laptop that I bought about 2 years ago from the Finland. It has Windows 8 is installed since the time I bought it. It also uses the Qualcomm Atheros AR5BWB222 wifi/bluetooth model component I think with the 10.0.0.225 drivers. I get very well recently with her. My wifi started acting like turning and return after some time spent. So I advanced and checked by users who have various problems with which they all reinstalled their drivers and it seemed to solve the problem they stated. So I decided to reinstall mine so I don't know what I thought so but I uninstall the drivers from Device Manager, which could be a mistake. I then visited the page of download from Acer for pilots and had the pilot-263, which is newer and wanted to install that instead, he asked me yet again to uninstall the drivers (since I did not uninstall completely before I guess, I don't know), and I did it and then reinstalled. After it's over, he asked me to restart and I went and restarted the computer. But after that, I noticed that there are no networks available in the networks to the taskbar section. I tried to uninstall properly then and reinstalled it restart each time of course. Problem remains even if I installed the old drivers. So I panicked and did a system restore (which was from the start > General > advanced since the control panel boot does not work "because of my firewall" as it is said could be due to DEP - no idea on that too-) and restored to a point which is 4 days before this date. He seemed ok, but I thought that the problem with the disconnection may still persist so I did correct this time reinstalling but same thing happens again and no network was found. Now I can't restore the pc at this point yet since him restore point removed somehow and I'm stuck with its current state as it is now. Can someone help with that, what should I do to solve this problem I have in my hands now, it confused me a lot. Can it be due to DEP or my Antivirus/Firewall (Zone Alarm installed on it now) maybe? I don't want to lose my current data and want to keep the pc as it is if possible. Thanks in advance.

P.S. The reason for me to uninstall the drivers via Device Manager has been to install the unofficial drivers from here: https://www.atheros.cz/atheros-wireless-download.php?chipset=74&system=7 but he said the drivers are for another system that Windows 8, but it's for Windows 8, which is what tells the site on the link? Can anyone confirm this drivers for Windows 8 or the site is a legitimate/trustable? If Yes can I manually install this driver whql by chance?

Found a huge thread on this subject, the intention to change the card wifi with a processor intel one now, if you are interested: http://answers.microsoft.com/en-us/windows/forum/windows8_1-hardware/windows-8-wireless-issues-qualc...

    I have been troubleshooting for weeks and am now bald from ripping my hair!

    Computer: Dell Inspiron 537 s Slim Desktop  w / Pentium Dual - Core CPU E5200 @250 GHz

    Cable router: SBV5220 Surfboard Motorola

    Now several months ago this desktop computer once more had SOME programs lose the ability to access the internet via an Ethernet cable.

    Affected programs:

    MS Internet Explorer

    Mozilla Firefox

    Avast! Security Suite

    Work of MS Security Update

    Ping works sites (Yahoo, etc.)

    Other computers connected to this network via WiFi - no problem getting on the internet.

    Run the network troubleshooter advises all is working properly, no suggestion.

    Attempted fixes:

    Turn off all extensions on IE (but don't forget Firefox and Avast! are also unable to access.)

    Disabled all start-ups and the package process

    Restarted in Safe Mode - still not able to access.

    Ran check complete virus, then check virus run start. Minor ad-ware 'virus' not found, all corrected automatically.

    Rebooted the router and the computer to infinity and beyond! s

    Tried other computers using the same ethernet cable connected to this wireless routers cable, no problem accessing the internet.

    Disabled functions package

    Off MS Firewall

    IP Reset configuration (memory: netsh ip net reset c:\resetlog.txt - without DOUBT NOT EXACT - OF THE MEMORY.) Command worked)

    As I said, this had happened before and then miraculously fixed itself after a short period (less than 1 week). This time, no joy.

    Of course, it's one of two things:

    (1) a configuration problem I just can't find/understand.

    (2) the problem of equipment more strange, more selective, in the universe.

    Anyone? Anyone? Bueller?

    Thank you more can I possibly Express for assistance.

    Hello team zig - zag,

    I wanted to thank you for your help. I finally broke down and reached out to our friends at Microsoft directly for assistance. They had me a role through all the things that you suggested (again). And finally (after many hours of phone and chat discussions) came up with an answer: "* shrug * we don't know what is the problem - choose a restore point and come back to that.» What I did. This has solved the problem of internet access, but created other problems I'm trying (nothing that I have to post here, they are specific to a particular program package).

    Still, I wanted to thank you for your time and effort on my behalf. I'm very, very happy!

    All my best,

  • You can remove an iPhone to iCloud via WiFi (no cellular network)?

    I recently bought an iPhone from a friend 5s. My friend's daughter had used the phone on the AT & T network until the screen was broken and their families have opted to get a new phone on a different network. Having managed to unlock AT & T iPhone (so they could be used on another GSM carrier), I asked my friend to make sure that the phone was "unlocked" from AT & T. All I can say at this point, the phone is no longer with AT & T.

    Preparing the iPhone for my own daughter, I realized that the phone was still connected to iCloud for my friend's daughter by the intermediary of find my iPhone.

    While I'm trying to get hold of the girl and the hope that we can use its AppleID password for my friend's iPhone settings, I now wonder if she'll be able to do remotely if the phone is not connected to the cellular network AT & T. I have consulted my home wifi network , but I hope someone out there can clarify if this can be done remotely via WiFi or if my friend's daughter must enter his AppleID and the password (or give them to me) directly.

    Thanks in advance for your answer.

    Sorry was a little confused, you ask a question on a Microsoft Forum Android.

    On android, you try to perform a "tie".  Depending on your operator, which may require add them a feature to your account to make it work.  There are several applications out there, that you can use to root your phone to install applications that will try to fake on the carrier.  Here's a piece of Security Council 'Root never your phone', it will cause problems and make you more vulnerable to exploitation thereafter.

    But back to tie, I guess that you do not want to pay for an app for a quick search of the Amazon AppStore poster a few promising ones:

  • the running program on myRIO with access to controls via wifi

    I built balancing robot using myRIO. It does not perform very well and I can control it via wifi. I have now the Setup is simple enough: I can control and set PID and Kalman (accelerometer gyroscope) values. However, there are significant delays associated with the wifi connection. Therefore, if I am happy with my performance robot WiFi (all the controls value) and then I deploy my program on myRIO - changes in performance of robots since the program is run on myRIO now and there is no bottleneck related to sending the data back and forth between computer and myRIO.

    To avoid this: is it possible to run the program under myRIO but have a link with all the necessary controls on wifi?

    Kind regards

    Drakon,

    Looks like you want to use your computer as a GUI that will read and write variables shared network your myRIO can also connect to.

    http://www.NI.com/white-paper/5484/en/

    It is quite common to all the treatment more push to a real-time controller while having a user interface on a computer that will basically just reading and writing shared variables.  I don't know if this is what you were asking, could you explain what you are currently on your myRIO and your computer, problems you have with your current setup and you want to change?
