• connection problem with my wired network:

  My multimedia PC running Vista (SP2) and is connected (wired) via a switch, and powerline Gigabit connection directly to my BT Home Hub. In the last month or two, I noticed a problem that when the PC starts it does not connect to the internet. If I open the network folder, I gives me the message that, because I'm connected to multiple networks, I can't connect to the internet. If I open the folder 'show all networks' it completely shows a connection to the Local network, but the connection seems to be two network - home and just describing it as 'unidentified network '.

  If I then turn off the adapter and re-enable it, it will connect to the correct home network and so to the internet without any difficulty, but every time I restart the PC I have the same problem.

  The reason for which mmediate why it's a nuisance is that I can not receive Windows updates, because the update is disabled at startup if no internet connection is present and cannot (I think?) be restarted by restarting the PC (cue endless loop according to the above).

  So my question is how to remove this 'unidentified network' if ever it shows up as a separate in a list. I prefer not having to try to reinstall the whole damn OS, but am at my wits end otherwise!

  When you have changed the Norton, have you used this tool to remove it?

• VMware View 5 PCoIP get a black screen on wide AREA network

  Hello community,

  I got a VMware View 5 Infrastructure with a vCenter Server, a connectionserver of view and some clients such as VMs.

  Internally, everything works - connections PCoIP and RDP do their job very well.

  Know that we want to publish the vDesktops over the WAN. Users must connect to the virtual machines in their laptops or iPad (or iPhone) at home. So, we have configured our firewall to open the IP Wan (194.209.166.xy) to the internal IP (192.168.199.xy). A DNS entry for view.xy.com shows the IP WAN. If the WAN connection to infrastructure display RDP works - but PCoIP connections shows a black screen after 10 to 30 seconds after logon. We never see an interaction of oder break Windows. The screen is black after the logoninformations in the client view.

  We have configured the connectionserver display settings as described in some articles here... 7

  The external url HTTPS: https://view.xy.com

  checkbox activ: tunnel connection secure user desktop

  PCoIP external url: 194.209.166.xy:4172

  checkbox activ: use pcoip gateway secure for pcoip Desktop connections

  We have forgotten to do some settings or is it an another workaround to work with PCoIP over the WAN?

  Kind regards

• Cannot connect HP D110 to my network using WPA2 wireless

  Hello

  I have a linksys router 160n with two apple airport expresses in bridge DHCP mode.  Each wireless access point's own channel: 1, 6, 11.  They share of SSID and password.  Security is WPA2. I have not activated the MAC filtering. I have multiple and varied devices connected to this network.

  Here's the problem: I can not connect my D110 printer to the network with WPA2 security.

  The printer can connect with security disabled but obviously that is not an option (or just WPA).

  Thus,.

  1) has any related person a D110 printer to a WPA2 wireless network?  If so, how?

  (2) the printer does support WPA2? (no WEP or WPA)

  (3) other tips?

  Thank you!

  OK, some other ideas:

  1. ensure that 802.11 g is turned on.  Other modes may be present, but g must be activated.

  2. change to channel 11 on the main access point (adjust others as required).  I know it's strange, but...

• Wireless and wired Internection connection problems

  Hello community,

  My first question concerns my wireless laptop connection (or lack of it). I rebooted my router (because I forgot my password), who restored the device to factory default settings.  When I've reconfigured the router, I was unable to connect to the Internet via a wireless connection. When I troubleshoot with Windows 7, it says that I need to connect an Ethernet cable from the router to the laptop.  However, it was not necessary when the connection to the local area network (LAN) via a public network worked without error.  In addition, when I check my wireless network connection, it shows that the signal strength is excellent and a connection is attempted, but without success.  When I open the network and sharing Center, there is no LAN.  Is it possible that something is blocking access to the LAN? It wasn't a problem, before I changed the router username and password the default user and password. Something is flooded with this situation.

  A second problem occurred when I tried to connect my desktop computer directly to the external modem from my ISP in which I work around the router. There is no Internet connection when this happened.  Before configuring the router via wireless connectivity, the direct connection between the external model of my ISP and my office worked without error. Your thoughts on these two issues are very popular.

  Thank you in advance.

  We're going to do in the first place the wireless and see if we can make it work.

  Go to the router configuration page (it can be www.routerlogin.com or an IP address, depending on your brand.) See your documentation for him.). Under "wireless" parameters must be a place to enter the password you will need to know to access the router. If it is always the default value (which will be probably if reset you factory default), then change to something unique.

  Open the network and sharing Center and click on 'Manage wireless networks' in the left column. Right click on your wireless connection and on the Security tab, select the settings of your router is to (WPA, WPA-2, etc.) and the type of encryption. Then enter the password that you put in the router in the box "network security key. On the connection tab, uncheck "automatically connect...". "for the time being. OK, and then restart. Check if your wireless network is working now.

  To connect to the modem, you may need to recover from the IP. Open a command window, type ipconfig/release and press ENTER. When that finished, type ipconfig / renew and press ENTER. Now you should be able to connect directly through the modem.

  Thing, that I forgot to mention, while you are in the configuration of your router, make sure that "Enable SSID Broadcast" (or a similar expression) is checked.

  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.

• 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!

• Connectivity problem - problem with the modem or the router of network

  I had a network with 2 computers.  The main computer was a Windows XP operating system and the secondary is a Windows Vista operating system.  There was a modem connection and the router. Due to a storm and a leak in my ceiling in my main computer got wet and I couldn't use it.  I have connected the modem without the router directly to the secondary computer, but it is not recognize the modem.  "Internet Explorer cannot display the webpage." So I ran the diagnostics and received a message that there could be a problem with the modem or the network router.  I did the thing 'ipconfig' and there is no gateway.  Is there anything I should do to make this secondary computer main computer?

  Hello

  If you use a router there is no primary and secondary, all the computers connected to the router are equal.

  Many Internet service providers allow you to control some form of autehtication (ID, PW) online journal.

  Your router and the computer humid probably were installed to authenticate.

  If the router does not use it.

  Otherwise, contact your ISP and ask for the help of authentication.
