New Win 7 computer cannot access the IP address of the network printer. Help, please.



UPDATE: we have found the solution to this problem, we, and that I posted an explanation as well as two ways to solve the problem in my 2nd post on May 5, 2015. Scroll down to it for the solution. Unfortunately, Microsoft does not allow the OP to mark one of their own messages as 'the Answer' so this thread continues to be listed as "no answer" when he actually answered me.


The original message follows...

We cannot sign a new Win 7 (64-bit) computer to a printer ethernet established in our local network of 'working '. We have reached the limit of our troubleshooting skills and expertise assistance.

Our Local network
The printer is a Dell 5100cn workgroup laser that is connected via an ethernet cable to a 10/100 workgroup switch 5-port Cisco/Linksys. The switch is connected to the built-in cable Motorola modem / 4 port gigabit router / WiFi access point. There is no server between the printer and the network.

Other computers on the network run also Win 7 and have no trouble seeing and using the printer. Some computers are connected via a gigabit ethernet cable to the router Motorola. Other computers connect wireless WiFi (once again, by the same Motorola device). All computers, including the new ones, are attributed to the same workgroup.

The printer has a static IP address. It also has an integrated Web page accessible within the network via a browser to view the status of the printer. All previous computers can view the status of the printer Web page by entering its IP address in a browser.

The new Win 7 computer
At the Windows command prompt, we successfully ping the IP address of the printer and received a return signal. However, we are unable to connect to the IP address of the printer (and status Web page) with a browser. And we cannot find the printer when install us the printer driver. We have tried to turn off the Windows Firewall and it did not help.

When we install the driver, move us as a 'local' printer and create a new "Standard TCP/IP Port" for her. We enter the static IP address of the printer and name the port. Define us the Protocol to "LPR", enter the name of the queue ("lp") and activate SNMP State with name of the 'public' community and the index "1". These settings have worked very well with our previous computers.

When the time comes to 'choose printer', we select 'have disk... '. ' and use the Dell 64-bit for this printer driver. But it does not work and do not print a test page. We even tried to install the printer as a 'network' printer driver, but it does not, either. In addition, the 'local' method always seemed to work best in the past.

The new computer has no harm to see other computers and devices on the network. For example, there is a NAS connected to the same switch Cisco/Linksys like the printer and the computer can access the NAS via its static IP address. The new computer can also access the internet. He can't use the IP address of the printer. We even tried to change the address IP of the printer, but that did not help either.

Despite the fact that the work - the network troubleshooter Windows command prompt ping indicates that the printer is not responding. What do we lack? Help, please.



I hope that this will be our last post on this subject. We have discovered the source of the problem and can offer two 'fixed' in case someone else runs into the same situation.

With the help of MSConfig and a process of elimination, we have disabled non-Microsoft services that were running on the computer until we discovered that "Qualcomm Atheros Killer Service V2" was the source of the problem.



Our new Win 7 computer contains a communication module ethernet/WiFi/Bluetooth e2200 Qualcomm Atheros. The manufacturer provides a '' Killer Network Manager '' for this system. Its purpose is to monitor and control the flow of data over a network connection in order to optimize for. For example, the user can choose to give the program A high priority and program-B low priority. This ensures that the program-A is less lag in the network traffic.

The primary market for this function, so far, has been the online game (where the name of 'Killer'). It allows players to channel the bulk of the bandwidth available to their game and away from other programs and services that are running at the same time. A response faster online gives the player the advantage it needs to get "kill him" before someone else.

This system of control of bandwidth has interfered with data packets of return of our network, clearing communication between our computer and our printer printer.

Difficulty 1


The simplest solution for us was to disable 'Qualcomm Atheros bandwidth control' for the ethernet NIC that has been accomplished by going to: Windows Control Panel > network and Internet > Network and Sharing Center > change the settings of the card (in the sidebar). Then we clicked on our connection to the LAN (our NETWORK ethernet card) and select the 'Properties' command Finally, on the Networking tab, we have disabled 'Qualcomm Atheros control bandwidth' and clicked 'OK' button to close.

All that was needed after that was a quick restart and we were able to access our printer even with the killer Network Manager and functioning of Qualcomm Atheros Killer Service V2.

Either way, we left the control function of bandwidth enabled for wireless (our) network connection because we do not plan on using this network printer when the computer is untethered to ethernet.

Difficulty 2


If you don't want the killer running Network Manager on your computer, you may be tempted to uninstall. Do not! Uninstall will also uninstall the drivers needed for your ethernet, WiFi and possibly your Bluetooth as well. We heard that some users have communicated with Qualcomm and were able to coax, on their part, the necessary drivers comm without luggage "Killer". But you don't need to do it, either.

All you need to do is: (1) remove the 'Killer Network Manager' of the '"start up" folder of the start menu of Windows (under "programs") and (2) using MSConfig, uncheck "Qualcomm Atheros Killer Service V2" under the ' Services ' section. Then reboot and you're good to go. The killer Network Manager and his service will not work.

Moreover, the reason for which we did not chose this method, ourselves, is because we see one deserves that available Killer Network Manager so that we can block network traffic to select programs. Solution 1 converts this easy thing because the Ethernet bandwidth control can be quickly activated again if she is ever desired. And we're leaving it enabled for our WiFi.

    To all those who can help you:

    I just got a new 550-110, windows 10 and I go through the initial Setup on Windows 10.

    So far, I can't find or access one of the titles of software included with the computer, such as cyberlink or Bang & Olufsen Play.

    The package contained little documentation, only a start guide and warranty brochure. No other established place of discs or other items, only the keyboard, mouse, and power cord.

    How can I start accessing these programs, in particular the Bang & Olufsen Play? I chose this model for the best acoustics, not the old sound DTS who never worked at the time where to play music.

    In Win7 ol ' well, you will get a list of all programs on the start menu, but the boys at microsoft know what we want, whether we like it or not. I know where to look in Win 7, but not the slightest idea in Win10, I tried a search of the whole and even computer watched the program folder files, but found nothing other than Amazon and Trip advisor (already in the taskbar).

  • Cannot access the network ERR_NETWORK_ACCESS_DENIED

    I have Windows 7.  Nothing works, I tried chrome (which will not even load) and Firefox (it has been a constant problem with gmail for well over a year).

    Cannot access the network

    Google Chrome has access to the network.

    Maybe it's because your firewall or antivirus software wrongly think that Google Chrome is an intruder on your computer and it blocks to connect to Internet.

    Chrome allow access to the network in your firewall or anti-virus settings.
    If it is already listed as a program allowed to access the network, try to remove from the list and Add again.

  • Win 7 computer cannot see the computers on the network

    We have 3 computers on our network. A desktop computer running a laptop running Win 7 x 64, an office equipped with Win Vista and Win XP. All 3 are connected to the same workgroup and are properly connected to the internet. The two workstations can see and the laptop on the network and can move the files to the laptop, but the laptop cannot see other computers on the network. Whenever I try to open the network to move files to another computer, the icon just mouse sits and turns and the page remains blank.

I don't understand why, if all the computers are on the same network, they can see me, but I don't see them. I am obviously connected properly so they can move the files to my computer.

  • Cannot access the network drive after trying to change the shared folder.

    I had a 80 GB drive connected to my E3000 for a few years and it worked without problem. I recently turned to a 250 GB Maxtor One Touch drive. When I plugged it, the router automatically creates a shared folder. I was able to connect to this folder without problem, but I wanted to share the whole score. When I made this adjustment and tried to save the settings, I temporarily lost access to the router. He gave me the standard page cannot be error message appears. When I got access changes seem to be made. When I try to access the drive of my laptop I get this error message, "the mapped network drive could be created", "the name specified network is no longer available". I rebooted and power rolled my router as well reconnected the drive.

    I think that since you have replaced your hard drive, old settings are configured may still on the hard drive of old. You can change the users and group so that it syncs with the new hard drive or start from scratch (reformat the hard drive).

    I have an old aio by one year of the HP Deskjet 3520 printer (a little over a year old).

    Recently, my computer (Dell) crashed (about 2.5 years).

    I have now purchased another HP Pavilion (8.1 64-bit-with 'apps' instead of programs) and when I now click on the printer icon to access the interface of the printer nothing happens...

    I tried uninstalling and reinstalling programs, but also updates etc., but it still does not work.

    I can now not for example do scanning to PDF and not to scan several pages in a single document, that I have a great need of.

    Everything has worked with my old Dell computer, but when I bought a new HP (!) it doesn't work anymore.

    HP support will not give me support due to that they claim it's a printer problem. And it's just maginally on a year - so not supported... It was when I bought a new HP computer, that he has stopped working! :-(

    The printer worked fine with my Dell computer recently. The problem came when you buy a new HP computer...

    Really bad HP Support to claim that it is a printer problem, which is a bit more than 1 year and refuses to support me, when the problem occurred the first time I tried with my new HP computer...

  • Cannot access the network - Get unspecified error 0 x 80004005

    Hi all

    I have a strange problem that I hope someone can help me with.

    I have a PC Windows Vista Ultimate, newly installed, all the patches applied. Any other installed apps don't except MS Office.

    Not my problem, I have a NAS drive on my network and can be accessed by different machines on my network (IE. \\NAS)

    However for some reason any my Vista machine has ceased to recognize this. Now I can only connect via an IP address (IE. ( \\

    Whenever I have try type \\NAS he says "Windows cannot access \\NAS... etc etc" with a "unspecified error 0 error Code 80004005 x.

    He used to work, but now it does which is very weird. When I click on diagnose says that it cannot find \\NAS. However, as this network drive has a web front end, when I type its IP address there is no problem at all and I can access it, but not through windows Explorer! I use a TP-Link wireless adapter. I have a LAN connector normal that I disabled and enabled with no effect (although I have not physically connected them)

    I can navigate to Windwos Vista machine to it seems to work very well.

    Any ideas?

    Thanks in advance.


    If the regular way, you connect a reader could not be used and that you were forced to connect by ip, get error 80004005 would make sense, because it means that the rights or false refused/insufficient access permissions. Your network can have a parameter saying denied access by ip address, so either you might find this setting, or find a way to solve the original problem, making it impossible to connect as normal to you.

    I would check the firewalls, because your firewall or the firewall of the NAS could have been changed to not connect to the NAS or do not allow you to connect, respectively.
