• Ad Hoc network. even if the network is active and is connected to the internet my devices cannot connect and then the network shuts down.

  I'm living in a college dorm and only have access to the internet via a hard line to my computer. So I wanted to give my other accessibility of consumer electronics set up an Ad-Hoc network and share the internet connection. When I originally set up the network it works fine, but after the devices go to sleep or I leave the room it stops working. I had problems to keep the internet connection to share continually, which I fixed it. I then had a DHCP problem with the hard line that has been resolved through troubleshooting function. Now, even if the network is active and is connected to the internet my devices cannot connect and then the network shuts down.

  Is there a way to create an Ad Hoc network that works similar to a wireless router, so when my computer is turned, it works automatically? If so, how can I make this happen without these problems?

  Hello

  I suggest to activate temporarily the antivirus as well as windows firewall and check if it helps.

  Important note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you need to disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network, while your antivirus software is disabled, your computer is vulnerable to attacks.

  Disable the anti-virus software

• Wireless devices cannot connect to each other using the router EA6900

  I use the 2.4 Ghz network and none of my wireless devices are able to communicate with each other...  I could not connect to a wireless printer to my laptop wireless (through the router) and thought it was unusual.  I tried ping does not work either.  I then plugged a cable ethernet to the laptop and could ping the printer wireless without a problem.   I tried other devices (wired and wireless connections) and it seems that no wireless device can ping any other wireless device.  If, however, one of the devices is connected, it works fine...  All wireless devices to connect to the router and internet without problem... It's just when they try to communicate with each other.  I have experimented with the desktop using the ethernet adapter, then the wireless adapter... same results.  My wireless using my previous router devices could communicate with each other.  It's almost as if this device has insulated AP running if this so-called it doesn't support that.

  Customer service said: I'm the only one with this problem.  Does anyone else have this problem?

  I have an ea6900 and it works fine for me. Sounds almost like you are connected to the guest network which would be sort of this way. Did you do a power reset? It has never worked? Try to remove the power and back to see if it clears up it.

• Cannot connect to the foglight suddenly

  Hello

  I was able to connect on foglight without problem in the past.  Currently I get "user has been imported successfully, but you cannot connect until an administrator grants the necessary permissions. Please contact your administrator.

  I get this message without worrying if I try to log in as myself or other AD id, what is the browser, and it also happens when I connect to a remote machine.  All other users can connect fine.  Has anyone ever heard talk about this?

  I also cleared my browser cache and rebooted my workstation.

  Hello cgolla,

  You must ensure that your username has some assigned roles so that you can navigate with vFoglight. It's basically what the message says.

  I assume that you are familiar with the steps to assign roles to a userID in User Administration dashboard in vFoglight.

• Cannot crop all of a sudden in preview

  I was just a preview photo editing and all of a sudden all the files I open already has "rectangular selection" checked. 'Culture' is grayed out. I can't uncheck the rectangular selection or choose another option to change.  I don't know what happened. Someone at - it ideas?

  It may be useful as you mentioned the versions of your operating system and application overview.

  For each preview version I've worked with, you use the "Rectangular Selection" tool to select part of your image, then on crops from harvest to this selection tool. (If the harvest menu item is grayed out unless you have made a choice which you can crop.)

• Some devices cannot connect to X 2000

  Hey guys, I've been setting up my new router Cisco X 2000 wireless recently and I have that works well for my laptop/desktop computers and even the PS3, but for some reason when you try to use the wireless on some of the other computers in my house it does not work unless you use a wireless guest account.

  Can someone point me in the right direction? I can't imagine what could be the cause.

  Oh and also, I use the Version of the Firmware: v2.0.01 if this is useful.

  Thank you

  James.

• 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?

  ... 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.

• Cannot connect on DMM & SnS suddenly

  Hello

  We manage the Cisco DMS 5.2 VmWare demo installation and today we are experiencing strange behavior. First license expired suddenly and after that the VmWare image has rebooted and same license apply again, he returned to normal.  Now, we are unable to connect to DMM or SnS of nowhere!

  I tried to reboot the system, but without any vain. Also tried with 3 different admin combination name of user and password and (root/admin) without success.

  However, the username/password admin working in the Cisco Digital Media Manager Appliance Administration Interface (IAA) and SnS!

  

  Any input would be appreciated. THX!

  Maxim,

  
  

  Since it is a configuration of VMware, the best is to go forward and

  reinstall devices in VMware.  You have access to the

  the IAA so you should be able to back up the configuration and

  then perform a reinstall and restore the configuration.

• Devices cannot connect to Mobile Hotspot

  When other devices attempt to connect to my access point mobile (Thinkpad is Windows 10 3rd gen x 1 carbon), it shows 'failed to connect to the network'': search DHCP failed. "

  I tried to use MaryFi and Connectify before (I forgot that Thinkpads have come with this ability) and they did not work.

  Then I tried Mobile Hotspot in settings of Lenovo and it didn't work so I uninstalled programs 3rd third and rebooted and Mobile Hotspot still does not.

  I would try to reinstall parameters of Lenovo, but I don't see how.

  UPDATE: I reinstalled the parameters of Lenovo and the problem is still there

  This is because the laptop itself must be on the active network connection such as LAN or devices that links won't be able to read the ip DHCP

• vCenter 5.5 device - cannot see all users/groups of ads after you configure SINGLE sign-on

  I'm playing with the device of vCenter 5.5 (studying if it is possible to move the device to Windows hosted vCenter).  We are running 5.0 vCenter, so I have no experience with SSO to date.  I've joined with success the vCenter for AD unit (I can see the object in AD) and then I added our field as a source-SSO in vCenter.  I made sure to use a host name COMPLETE of the device that I've seen a few problems with join the domain if the hostname was not in FQDN format.  When I set up SSO, I used "Active Directory (Integrated Windows Authentication)," and then "use machine account" - which, from what I understand, all that is necessary is that I joined the field of unit - which, as I said, seems joining our field.  When I added the SSO domain, there is no errors and I now see in the list.  So as far as I know, the configuration for the SSO was entirely free of errors.

  However, when I try to add resources to AD to vCenter (for example to add ad users/groups to the vCenter administrators group or assign role permissions to objects in vCenter) navigation for our domain window just, hangs in the web interface, I see a little blue bar progress turns forever and in the Windows GUI for vSphere client the browser window just hangs and I have to kill the process.

  I missed a critical step in the configuration of SSO for AD?  I'm not supposed to use "computer account"?

  Any help is appreciated.

  I had the same problem as you and and the fixed by adding a PTR DNS for a Windows domain controller in DNS. I came across a VMware troubleshooting document (not exactly the same problem, I had) and I gave it a try and it solved my problem.

• Satellite C660 2QH WLAN problem--loss of connection all the ~ 30 min

  Hello world

  I just bought a SAT C660 nine Toshiba and I faced a strange problem - I lose the internet connection every 30 minutes for about 3-5 minutes, then it connects all of a sudden again.

  I've been reading about the problem here and I fixed my power settings (although this also occurs when the laptop is plugged in), and I installed the new WLAN driver: 1005.19.0420.2011 (my Wireless LAN Adapter is: 8188CE). I thought that he that could have the problem in my anti-virus program, so I uninstalled. A few restarts later everything was as before - problem persists.

  Help, please!

  PS. I'm from Germany, where this is relevant.

  Hello

  Are you sure this isn't question of Wlan router?
  It would be interesting to know if you have the same problems with other devices connected to the Wlan.

  Next to the idea that this could be a router issue I think you should check some WLan Card settings.
  In the Wlan card-> properties-> tab Device Manager to disable the option to turn off the device to save power.

  You said that you have installed/updated test driver the driver from Realtek page too.

• Cannot connect to more than one mail account after the upgrade to Sierra

  I have several provided ISP e-mail accounts that work successfully for a long time on elCapitan.  After the upgrade to Sierra this afternoon cannot connect all accounts and I asks me to enter the password.  Why isn't Sierra pick up the passwords of my trousseau?

  Oddly enough, my Hotmail account seems to be ok.

  How can I fix this without having to re - enter all passwords?

  As a result of the foregoing, I found that my connection Keyring contains entries for all of my email accounts.  However, these dates are back in July 2011.

  After an episode of lost or stolen iphone, I had to update all of my passwords by e-mail in February this year (2016).

  Search in my keychain, I found dated entries for my email accounts in iCloud Keychain section.  I don't think that I never activated iCloud for my email.

  How the entires of e-mail account eventually sub iCloud and why the old entries from email account not updated?
