am looking for a solution, but nothing works... anyone can help?

Hello..

Maybe corrupt network preferences.

Open the Finder. In the Finder menu bar, click go > go to folder

Type or copy paste the following text:

/ Library/Preferences/SystemConfiguration

Click OK, and then move all files in the SystemConfiguration folder to the trash.

Restart your Mac. See if that makes a difference.

Your Mac will generate a new SystemConfiguration folder for you.

  • How can we keep our ipad to disconnect wifi?

    We use an ipad to connect to our timeclock but it keeps disconnecting WiFi. We have other computers and Kindle that are in the office, but they

    Don't disconnect wi - fi. We need the ipad to stay connected 24/7 for use as we are a company that is open 24/7. How can keep us connected?

    Thank you!

    Do you have connected? If the iPad goes to sleep and is not plugged, it switch off Wifi. But even if it does, it should resume as soon as you wake up.

    The problem may be on the side of the router, too. You can check your router settings.

  • Update iOS 9.2.1 keeps disconnecting wifi

    Since that I upgraded my iPhone iOS 9.2.1 as my wifi guard disconnection during the use of the Internet. I tried to restart my phone but without success, not even when disconnecting wifi and turning back on.

    To THE point that I had to go back to the settings wifi and turn then in 2 or 3 times every minute at its maximum; normally all less than 20 seconds as he attempted to enter the suppor of apple. Thank God I also use the edge of s6 Samsung Galaxy on my other number and sync all items from my iPhone to it. I will use my Samsung until fix you this and I'll get back to the iPhone as I prefer to use it on any other phone.

    Settings - general - reset - Reset network settings

    (You may lose the saved WiFi passwords)

    Then restart your phone - without loss of data - hold down the buttons off / on and at home until you see the  logo and allow the normal up to start

    See if that makes a difference

    If not, then reboot your router - cut its power supply for 30 seconds and then plug it back

  • External hard drives, disconnect WIFI

    HP Pavilion g7 2269WM W / Windows 8.1(64bit)

    I recently bought an insignia powered USB 3.0 hub to connect 2 external HARD drives to my PC via 2 USB 3.0 ports 1.

    HARD DRIVES-

    1 western Digital My Passport Ultra 500 GB

    2-500 GB SATA for another laptop put in an envelope.

    Both work very well plugged alone, plugged into the hub with the hub plugged on the USB 3.0 port NO.

    But the second I connect the hub on a USB 3.0, wifi off, and sometimes 1 records are found.

    When I unplug the hub, the wifi continues to work.

    I tried to do this with the hub plugged into the power supply and no, same results.  What is the question a problem wifi? I don't understand how all this is still linked to a network connection.

    Hello, @alyusha22

    It seems that when you have your external hard drive connected via usb 3.0 there is a conflict with the wireless. I will try to help you with this.

    First update all the drivers that you can. You can do this with the Wizard Support HP, or from this page: drivers for laptop HP Pavilion g7-2269wm.

    Other possible causes to this, is the radio frequency.

    This is an Intel document that passes over the issue in depth: USB 3.0* Radio Frequency Interference Impact on 2.4 GHz wireless devices

    I hope that it helps anything here.
    Thanks for posting on the HP Forums.

  • Satellite C660 - yellow warning sign - wifi access

    I have internet problems. I connected the laptop to my internet and she just this yellow alert sign in the bars of the connection. -L' display there is no internet. IM using windows 7.
    When I click it, it says: "restricted access". I used internet on my PC and netbook, wii and they don't seem to have these problems.
    Sometimes, it works very well. However, it only works for a few minutes, then stop working again.

    In addition, the quality of the webcam is really poor. It's really blurry!

    Hey Buddy,

    I found some similar discussions on the problems of Satellite C660 WIFI:

    It seems that you need to disable management feature in Windows to energy WLAN power management and update the WLAN driver to the latest version.

    The user ghostruane has also written an interesting publication. He disabled the network adapter in the Device Manager and it helped :)

  • Fuze 4 GB warning disconnect and reconnect to Windows 7 pc... when the battery is low.

    So I just got a rocket and I love it.  Done a good deal about it.  Windows 7 picked it up and transfer of music is not a problem when the unit is fully charged.

    What IS a problem, is that when the battery is low and I have to plug the "rocket" on my PC to load... it keeps connection / disconnection.  The program of control of rocket guard Center popping up and go, arise and disappear... frustrating.  I tried the DPW and MCP modes (actually in DMC mode on the control panel is not everything and it does not recognize that the device is connected).  I've tried different USB ports.  No hub at issue here.

    Here's the kicker... If I load the "rocket" first (plug into a USB Kindle charger), once it has loaded it connects very well.

    Ran the update of the firmware and I'm on the latest firmware it was available, 1.02.31.

    I would like to know how to solve this problem, because I don't always have the small USB Kindle charger with me, and that would well be load from a PC... which is what the original, right intention was?

    Except that I like it and really dig the FM radio tuner.  It is very bad!

    Hosers, all.

    Usb hub 4 ports powered solved my problem.  'duh, I think yer cable is bad' I DO NOT.  Apparently, the "rocket" sucks just too much power.

    So I solved my problem with a $ 5 usb hub.  Yippee.

  • Linksys router WRT160N v3 warning disconnect and reconnect

    Hi all

    I know that you've all probably seen this thread before. (I know I have).

    I have a WRT160N v3 Linksys router and it keeps disconnect them and then reconnect. It disconnects wireless only. LAN still works fine.

    I tried many different methods to solve this problem, but none does not seem to work.

    I'm very disappointed with the quality of the product. He did everything since it was purchased. I personally would have sent in for repair, but others in my household would not have agreed to that.

    Additional features:

    -Firmware Version 3.0.03 (no later than as of July 2010)

    -A a SSID set to broadcast

    -A encryption WPA2-Personal

    -Mixed-mode network

    -Width of the channel set to Auto (20 MHz or 40 MHz)

    -Channel set to Auto

    Please help me solve this problem.

    Thank you in advanced.

    In my view, that it is corrected. I'm using dd - wrt firmware instead of ciscos

  • warning disconnect Wi - Fi, laptop computer freezes when troubleshooting

    I have an Acer Aspire 5742, running Windows 7 Home Premium.I have had problems with my connection Wireless for 3 months now. It keeps disconnecting after 2 min 3. When I troubleshoot the laptop crashes as soon as it comes to solve. I turn off the power button. So basically I can't use the wireless connection and I can't troubleshoot it no more. No one knows how to fix? My network provider is unable to help because it is a real problem with the laptop and not on the network.
    Thank you
