• Wireless network connection problem

  Nice day

  I have a wireless network connection problem and I ask for help to resolve.
  What surprises me that this problem appeared suddenly, I used to connect to the WIFI correctly but two days ago my laptop could not connect to the WIFI and more.

  Other devices and computers connect with success so I think that the problem in my laptop.
  I don't have any changes on my laptop or windows, antivirus, drivers... updates or installed new software.
  Troubleshooting of Windows detected 'router or access point issues '.
  -Reset the router does not resolve the problem
  -Network adapter is enabled.
  -State of wireless card "working properly" and "update".

  I read a solution on this site, which was to change the properties of the wireless adapter, but the changes mentioned does not appear in the pilot of my laptop...

  * My laptop info. :
  DELL INSPIRON 3521
  Windows 7-64 bit
  Dell WIreless 1703 802.11b/g/n(5.2GHz)

  Sorry for this long to make, I appreciated all the help.
  Thanks in advance.

  Hello

  Have you tried to reset your laptop to a time before this issue started with a Windows 7 Restore Point?  If it is a parameter change or software this restore point can help solve what is at the origin of the problem.

  I'd also, of course, when you are resetting the router, to make sure that you let it sit for at least 30 seconds to a minute before plugging power back in.  You may need to do a few times to clear his memory to be able to connect.

  In addition, have updated the drivers for the wireless card?  What version of driver currently installed in the system?  You can consult our support site, enter your serial number and click on drivers & Downloads to find the driver for your wireless card.

  Finally, have you tried to empty the wireless profiles that are currently stored in your system?   If you delete the profile current wireless (which is to control your connection to the router), reboot your system, and try to reconnect Windows will rebuild the profile and hopefully allow you to log in again.

  I would like to know if any of this helps.  To help resolve this more effectively please click on my user name Dell Todd and send me a private message with the Number of Dell Service from your system.  Please keep all troubleshooting and discussions on this thread open so that others can find the information they need to solve their problems.

• Failure of the motorway E - there are network connectivity problems or this peer has different support encryption (AES / non - AES software)

  I do a bunch of highway E and C, but it I show error on cluster of highway E:

  Failure - there are network connectivity problems, or this peer has the support of different encryption (AES / non - AES software)

  This highway is part of a cluster, but is not the master of the configuration. Configuration changes made on this highway may be lost. More information about the Clustering help page.

  !

  What is the solution to fix it?

  Locally add cluster of highway or having to make cluster of 4 motorway between locations?

  How far are the peers of the highway on the other, what is the round trip time?  This should be within 30ms.

  Can you confirm that all highways in the cluster have the same keys option installed on all peers, as it is a requirement, call license quantities can be different, but the features option enable/disable keys must be the same.  Additionally, make sure that the version of the software installed is the same, that you have a version mismatch or could be active where encryption the other not.

  Regarding the "this highway is part of a cluster, but is not the master of the configuration... '. "this message is normal for a node that is not the master, as it is said just only make changes on the master, since all changes on the slave will be replaced by the master.

  Suggest you watch on creation of Cluster Expressway and maintenance Deployment Guide (X8.8) in case you have not yet.

• Home wireless network connection problems

  What should I do if I normally connect to the wireless network does not appear?  It is not a network card problem, because I can connect to other wireless and school and other places.  I tried to reset the router, ping and by unplugging and seeing what I could understand on the computer at home, but nothing does.  Any ideas or suggestions would be greatly appreciated.

  Thank you.

  Hello

  Have you tried other computers to connect to your router? You use both wire and wireless
  connection?

  Unplug the modem and Router 3 + minutes. And then reconnect the modem - when it is running
  Plug in the router - when it is running - restart the computer. This is known as a hard reset.

  Check with your router manufacturer support.

• With device log Insight network connectivity problem

  We manage the virtual appliance 1.0 - beta and I noticed that the virtual appliance will fall the network periodically for a short period. I had constant pings, it will and it will just stop respond for anywhere from a few seconds to several minutes. You can also see in the capture where the data is missing in the user interface of screen attached. I know that we are not the problems with our ESXi hosts or dvSwitch because there are many other virtual machines running on the same host ESXi and same VLAN and they are not network connectivity problems. Does anyone else know this?

  Sounds like a network problem. Perhaps you have a dual IP / MAC address on the network? Do you perhaps have a routing problem on the network log Insight's sitting on that?

• Satellite U300 - network connection problems

  I have problems with my laptop network adapters. The laptop is not able to connect to the internet with wired or wireless connections. I tried to update the drivers of the cards, but this does not solve the problem.

  In the Manager section of devices under network adapters, all cards have an exclamation yellow next to them and "Device status" is for the cards ' * this device does not work properly because Windows cannot load the drivers required for this device. (Code 31). Click "Find solutions to send data about this device to Microsoft and to see if there is a solution available".

  In addition, on reboot the computer, Windows prompts me to install the driver software for * Realtek PCIe FE Family Controller * and * Intel (R) Wireless WiFi Link 4965AGN *. "Whenever I try to install the drivers, it fails and the error message ' * cannot open the specific driver for this device registry key *" appears. I even tried to install the Realtek Vista diagnostic tool and the program fails to run but produces the error message ' * Please install protocol driver *'.

  I tried to restore the system to a date that I remember not having problems but the restoration does not end. I get a message telling me that the restore has failed.

  _Drivers: _ Realtek PCIe FE Family Controller - Version on laptop: 6.227.902.2009 (I think this is the most recent version)
  Intel (r) Wireless WiFi Link 4965AGN - Version on laptop: 12.4.3.9 (current version 13.0.0.107 do not install it)

  Can someone advise me on how I can fix this?

  Hello

  It seems the LAN and WLan driver are not installed properly

  Are you using the right drivers?
  What U300 do you have exactly?

  To my knowledge, the error message is usually for use of non compatible drivers
  Try to install a diagnostic tool of material such as Everest, Avast or Sandra.
  This should help you to get more details on the Wlan and LAN, then you might find the compatible drivers!
