• HP LaserJet M1522nf begins to lose the network connection

  Hello! I have HP LaserJet M1522nf and I use it for about 1 year maybe, but since last week, he begins to lose the network connection (ping failed, web interface does not work too). To be correct, the printer is connected directly to the network through an ethernet cable, and the cable is perfectly fine. His work when you turn it on and for the next 5 to 15 minutes, but after that it lost connection (tasks start fails).

  I really like using little aid, some perhaps of advice. Any suggestions?

  Hard reset the router to factory settings and reconfigure your settings.  Pass the cable to a different port on the router.  You said that the cable was good... change anyway.  Try now.

• Continuous wireless network adapter lose its network connection

  It used to work very well in the beginning, but after a many windows updates, my laptop has started to lose the Wi - Fi connection every several minutes.

  ... I suggest you to update BIOS, chipset and wireless network drivers these links and check if it helps...

  Hi, Yann,

  I updated the driver, but it did not help. Update the chipset has probably not because I have AMD (the update says that I don't have the required devices). BIOS has been updated some time (I have the latest).

  I also searched other topics and did the following:

  Disabled IP assistance service;

  Value another configurtion IP: manual and entered a fixed IP address and the default gateway.

  Turned off the Windows Firewall for this network.

  The problem seems went, at least for now, although I don't know what stage did.

• Satellite A110-378 loses the WLan connection during downloads of big

  Hi all
  I have a Toshiba Satellite A110-378 series and a wireless network problem. The card is an Intel 3945abg. I can connect with the router ADSL (USR9106) with WPA security is enabled. I can navigate on the Internet, but for a large download (or shall file a copy) the connection stop responding. Windows still displays the connection, but after a few minutes I got an error message.

  To re - establish it, I need to 'fix' the connection. The driver is the latest in Intel, and I tried to disable the power settings. Seems that the problem is the same with my ethernet card (I'm the check).

  Any ideas?
  Thank you very much.
  Alessandro

  Hi Alex

  In my opinion, there is always possibility of losing the motivations and download WLAN connectivity more I prefer the LAN connection (sometimes runs during the night). Check this with connection to the local network, but perhaps is another side responsible for the interruption of the download.

• SG 300-28: duplication of port: loses the network connectivity of the destination host

  Hello

  We have two SG 300-28. On one of them, I have configured the port mirroring because a host behaves strangely. When I create the mirror, the host connected to the destination port is not available any longer, for example, it does not meet a ping. Port source packages appears on the port of destination, but no package intended to be the host itself. East - this behaviour right? I agreed that the host on the destination port is always accessible, as it would be without the mirror.

  Bernd

  HE Bernd,

  Yes. This behavior is just. That's how Port Mirroring works. The host connected to the Destination port loses its connectivity and it can act as a monitoring device using programs like WireShark (and monitor packages coming to and from the Source port (s)). All configurations on the destination port are substituted.

  Let me know if you need assistance,

  HTH,

  Vijay

• Satellite Pro L300D loses wireless connection randomly then can never find

  Hello

  My Satellite Pro L300D loses the wifi connection at random times and I have to turn off the network for the L300D BT box to connect again. Throughout this, my other laptop Toshiba works fine on the network, as does my PC, so the network is fine.

  It's incredibly frustrating because I have a new baby and get NO SLEEP - I just need the L300D blasted to work!

  Any help would be good and would save me lose any more hair.

  Thank you

  James

  one of the two: or the Ruter have electrical problems, but you said that another computer is not working properly, so it must be a physical problem with the unit your problematic computer wireless, if wireless is the drop of water at all times, you must check this problem with a service provider.

  If you don't know where you can find one, visit this Web page to locate your nearest Prov. Serv.

• Apple TV loses network connection

  Why my Apple TV loses its network connection? Each article I found said it's your network... It is not my network. I have 4 other Apple TV on my network of 5 ghz and they work great. I've seen articles that say it is the signal of my AirPort Extreme. It is not the case... As I said previously I have 4 other Apple TV scattered throughout the House and Apple TV that has the problem is sitting right next to the AirPort Extreme. All 5 Apple TV are Gen 3 and the updated version. So is there anything else I can try before buying a new Apple TV?

  Other devices work does not have a network problem.

  You can get a report ffrom istumbler, netstumbler or similar to see a current state of the network. This will give you the strength of the precise signal, noise, networks nearby. With the help of Ethernet will also check. You can also test it on another network

• In loose wireless network connection once the last update of definition for Windows Defender - KB915597 is installed.

  Hello.
  The problem I've been is that I lose my network connection to my wireless network when windows downloads and installs the latest update of Windows Defender (definition 1.55.1119.0).
  It can detect the network and others nearby, but cannot and does not connect to my network.
  The only way I can solve the problem is to do a system restore to an hour before the update was installed and disable automatic updates.

  I have a HP Pavilion dv9000 running Windows Vista Home Premium.

  Thanks for any help.

• Printer all in one, loss of network connection

  I have a Photosmart HP 5510.  This is only about a year, but is now always lose the network connection.  I configured correctly (it actually worked!) to the wireless router.  Most of the time now when I need to print, it tells me that the printer will not communicate with the computer.  I took it out of the network, put it back on, and he said: it is connected.  I have not printed the network status page, everything is OK, no problems found.  So I'm still not able to print? It's very frustrating.

  I set it up to my Macbook Pro and my iPad.  He has worked on both devices, but I can't seem to get it back in shape now.

  I have looked on the forum here and have seen many many people with the same problem, but most seem to be using a Windows operating system.  Any ideas on what to do?  I really need to print!

  I did reset the router that worked. It happens every few weeks for some unknown reason. I'm in. fiber.

• HP1102w continues to lose the network SSID

  My Laserjet 1102w wireless worked fine for about a year.  Now he has started to lose my network connection.  When I print a status page, it shows that it is "connected" to SSID HP8AA7DC, which I assume is the default value of HP, and had no IP address.  I re-installed the printer 3 times in 4 days and it works fine for a day, then the same thing happens.  I am running Windows 7.  To my knowledge, nothing has changed recently other than to have an extra laptop using the network (never printed however).  This could be the cause?

  OK, thanks for that.  We will set an IP address of the printer:

  -Print a the front of the printer Network Setup Page. Note the IP address of the printer.
  -Enter the IP address in a browser to reveal the internal settings of the printer.
  -Choose the network tab, then wireless along the left side, then on the IPv4 tab.
  -On this screen, you want to set a manual IP address.  Set the IP Address of the printer to the same as its IP address but replace the latest figures with "250".
  -Apply the subnet 255.255.255.0 (unless you know it's different, if so, use it)
  -Enter the IP of your router (on the Page of the Network Config) for the gateway.
  -Enter for the first DNS 8.8.8.8 and 8.8.4.4 for second DNS. It's Google DNS. You can choose a different external DNS if you wish.
  -Click 'apply '.

  Now, stop the router and printer, start the router, wait, and then start printing.

  After that, you will have to redo 'Add printer' using the new IP address.
