  • Names of the devices connected to the router

    How can I tell the names of the devices that are connected to my router E2000? Cisco connect says I have 4 devices but I only have 3. I'm trying to understand source of the 4 device.

    Open the Cisco connect software. Go to "Setting up the router" and click "Advanced settings". Who will open the router configuration page.

  • EA6500 unable to connect to the router after Time Machine

    Just got an EA6500 - updated to the latest firmware available.

    I have attached 2 x WD NAS and 1 x WD through the USB port of the device.

    Each time after I finished running Time Machine on the MacBookPro (written to one of the WD NAS), I can no more connection to the router as neither the local IP, or the cisco connect cloud. The error message I get (loosely formulated) is: unable to connect to the router. Please ensure that the router is connected to the internet.

    At this point, all the devices connected to the router (wired and wireless) still can access Internet perfectly. Only the console of the router is therefore more accessible.

    Anyone else have the issue?

    Any ideas on how to solve it?

    Contact support for Cisco and the person advised me to do a factory reset (even if the router is new with no customization!). Regardless, it now works correctly. Cisco Cloud Connect works always before, during, and after a Time Machine.

  • Satellite L500D: WiFi remove connections to the router

    My bars of Toshi Saturday 1,2,3,5 equates to dropped the WiFi but when WiFi is at 4 bars, it's the best thing since the fire.

    Recently, my laptop started to remove connections to the router and the router is that a step of 4-5 come out in the kitchen of my house. And another problem is that my room seems to be a dead zone.

    If I turn on my laptop, I am required to get out of the kitchen and stand near the router until it connected, but if I'm sitting in my room, 3 bars, and said "(the WiFi name) cannot be detected/connected."

    Any who want to enlighten me on what's going on?

    Mr.Delta

    Simply said, the Wlan router signal is too weak and this causes disconnection
    I have some advice for you;

    -Update the WLan driver
    -Card Wlan definition of control; You should go to Device Manager-> properties-> Advanced tab WLan card. You will find some options that allows you to change the standard WLan (802.11 A, B, G, etc.) and you can also check the WLan channel and improve the signal
    -Disable the Wlan Card saving

    Good luck

  • Get the IP addresses of the devices connected to the WiFi network

    Hello guys,.

    I've been looking around and trying to understand this point, but I don't have a solution. The problem is to get the local IP addresses of all devices connected to the WiFi point of access/router connected to my BlackBerry. Similar to the way in J2SE nature you can get the IP using InetAddress.getLocalAddress () and then browse ip addresses and call InetAddress.getByAddress (ip) to check whether the device is accessible. Possible is something similar in BlackBerry or not?

    No, the fault was entirely mine, I misread your message.
    no idea how to do that, there is no access from low level of the network interface and the API is really limited.

  • WIFI connects to the router but no internet connection on 15R 3521

    Hi, the new laptop 3521 with Win7 Pro the WLAN will connect to the selected wireless router but is unable to establish an internet connection.

    WLan Driver 1703 was duly installed once the Chipset driver was installed, as recommended.

    Fortunately, other mobile devices to connect to the same router. Ubuntu on this laptop was also happy to connect to internet on WIFI, only Win7 fails.

    Disabled the Win7 firewall, but no change. This connection, unidentified in the network and sharing Center.   Router SSID etc have been entered correctly. Remove the WLAN profile and not reinstated, no change.

    Tried to connect to another router wireless with the same result. I can only run this laptop on wired connection to the router.

    I am at a loss as to what other steps I could take to correct this key WLan / internet access.

    Any suggestions would be welcome. See you soon.

    Hi love,

    Thanks for your advice. I deleted the profiles (two identical found!), also removed all entries of all WiFi routers in Win 7 registry. This step has not resolved the problem.

    However, I found the reason for the connection problem and the solution is the following:

    In the wireless connected (TP-Link) router, wireless--> channel settings is set to 'AUTO' (which is to select automatically 20 MHz or 40 MHz).

    In the device driver Dell WLAN 1703 (properties--> advanced--> bandwidth 802.11 n, the value has been set on (ie the Atheros is the default!))  "20 MHz.

    Once I put the option value "20 MHz / 40 MHz Auto", the connection comes to life.

    What a relief!

    The question is now completely resolved. Thank you to all who have contributed.

    Better with respect to Dzsino.

  • 9.3.4 disabled wifi on an Ipad, but it connects to the router. Just don't download at all

    IPad was working fine, but I've updated to 9.3.4. Now Wireless does not work. Shows connected to the router, but nothing happens, but say unable to connect to the server, error trying to access the internet or by mail. Also turn continuous flashing VPN gray to green, then again, but we have never set up a virtual private network. Don't know if it is connected. Have you tried

    1 disconnection / reconnection to 2 routers that work very well for other devices

    2 reset wireless via settings > general > reset > reset network settings and then hang up again

    3 airplane mode on, wait a few minutes, then shut off again

    Overall, the router will connect to any time, we put the password, but there is no transfer of data. 3 other devices work fine with the router. Don't know where to go from here, or if it is possible to back out from the upgrade. Anyone else having this problem? A research increase the same problem.

    Thank you

    Anything that causes the problem is not specifically 9.3.4, which fixes just a security breach. Have you tried to restart routers?

  • iMac connects to the router of Linkysys WRT1900ac

    I am trying to help a friend get his iMac 12.1, that is running 10.11.4, to connect to a new Linksys WRT1900ac router.  The router is a novelty in this House, is in the same room of 10 x 12, as the computers listed below, and the installer was using the Linksys recommends the method, which is to let the Linksys to make adjustments.

    Here are its configuration;

    The router is connected to a cable modem, ISP and the following devices are connected to the router and works well;

    Via ethernet

    Windows 10 PC

    AT & T cell phone extender

    Ooma VOIP

    Wireless

    iPhone

    iPad

    Notebook PC

    While troubleshooting my MacBook 5.1 also allows to connect without problems to the Linksys router.

    Note that her iMac connects without problem to the wifi network Netgear Guest unprotected from its neighbor.  I also installed in his room my 1st generation Airport Express, which has added a second wifi network but without access to the internet and his iMac connect without problems to this wifi.

    Here are the steps I took to try to solve this problem, and they were unsuccessful;

    ➔ Scanned for malware/adware with Malwarebytes and found nothing.

    ➔ Ransacked after the files in/Library/Preferences/SystemConfiguration and restarted

    com Apple.Airport.Preferences.plist
    NetworkInterfaces.plist
    Preferences.plist

    ➔ When the previous did not work I trashed all the files in the folder/Library/Preferences/SystemConfiguration except "com.apple.boot.plist', which would not remove and rebooted

    ➔ Created a second user account and still not able to connect to the Linksys router

    ➔ Repaired permissions

    ➔ Created a new location in System Preferences > network and added the OpenDNS addresses and in the material value MTU 1453

    ➔ restarted in safe mode and not still could not connect

    Firmware on the router Checked ➔, which is updated

    ➔ Reset SMC

    ➔ reinstalled El Capitan via the App Store

    That's all I could think about.  I'm puzzled.

    I checked the router and everything seems ok, but I'm no expert.  There may be something I'm not contagious.  I have seen that he has no MAC filtering set up in the router, so this isn't everything.

    Please tell me if there is something that I'm on.  Is there something in the router, that I need to change?  There are other files in the Mac, I need to delete?  Is there any other troubleshooting steps I can take to identify this problem.

    Any help would be appreciated as it is a total mystery to me.

    There are a lot of variables, but start with some basic info. So on her iMac, if you click the wifi at the top right, you can see his router listed?

  • iPad can't connect to the router

    Hello

    I have a WRT320N router with firmware version 1.0.01 build 008.  I just got an iPad and so that it can find my router, I can't access the WiFi when I enter my password.  I can use the router with my laptop so I know the login and the password are correct.

    I saw two directors here suggest the same thing.  And one person said it worked.  The same directions were:

    Try changing some wireless settings on the router.

    Connect the computer to the router with the Ethernet cable. Open the router configuration page.

    Click on the wireless tab and put in manual configuration. Change the channel to 11 wireless. Save the settings.

    Go to the wireless tab and click the settings advanced wireless.

    Change the tag to 75 interval, RTS threshold to 2307 and 2306 fragmentation threshold. Save the settings.

    Try to connect to the wireless network again and see if it works.

    My problems are:

    1. I think that my computer is already connected to the router with the Ethernet cable - I want to say that it is an Ethernet cable attached to my computer and my router - in slot 1 on the router

    2 - the only thing I know how to access is the Linksys EasyLink Advisor.  What and where is the router configuration page?

    Thanks - I wouldn't think that if I can't get my router to work, I just lost money on an iPad only WiFi and will instead get one of these devices to attach to the iPad that allows you to connect to wireless internet - like device "clear."

    Read the user guide. The web interface is at http://192.168.1.1/ unless you changed the address LAN IP of the WRT.

  • EA6500 only shows no device connected to the switch of working group 5 ports

    I just replaced a defective Linksys e4200 with an ea6500.  After assistance by phone, I got to the top and work, but only one computer on my LAN is not displayed.

    I connected an 8 port 10/100 switch Linksys my 4200, and my wife's computer was connected to that.   The computer displays the IP as 192.168.1.133 and it is connected to the internet with my router again.  But the ea6500 does not show a device with the ip address.  Instead, he shows what he calls a network with the IP 192.168.1.130 device.

    How can I see the devices connected to the switch 5 ports and determine which ip addresses, they have been assigned?

    I use a switch with my network with a router EA and it shows the devices correctly. Turn off the computer which does not appear in the list of devices and check to see if any device will appear as offline adter who. Remove from the list of devices, and then restart the router. Once the router is ready, open the page of the router again and turn on the computer and check if it will be detected correctly. I hope this helps.

    Edit: Check and make sure you have the latest firmware loaded. Otherwise, update the firmware and do a reset after the update of the firmware. Check your list of devices after that.

  • HP 4500 g510n-z-printer connected to the router but not responding do not

    Hello

    I got this printer (HP4500 G510n-z) for 3 years. This worked without any problem until I changed my router and installed a nas on the LAN Server.

    Now the printer is connected via WIFI to router and is perfectly installed on computers connected to the router. But it does not work. I used HP Print-Scan doctor and he finds the device, but it was not connected. I tried to connect to the printer IP of all computers, but I have not received any response (using ping, it doesn't have 75% of the package). On the router configuration page, the printer is connected to the usual IP and on connected computers the TCP - IP is configured correctly.

    I have tried everything and I managed only to reboot the router. But it did not last, each computer remains connected only until you restart the PC nex.

    Sorry if I'm not too clear, please don't exitate ask for more details. Thanks for your help!

  • HP Envy 4500: Printer connected to the router, but will not print wireless Macbook

    I want my wireless printer to work on my macbook, but I can't. I tried setting up on the HP utility to connect with the router as the mac and printer on but it does not work! It indicates that the download was successful, but the device was not reachable. I don't really know where to go from here and any help would be really appreciated. Thank you.

    Hey @miriamnimmo,

    Welcome to the Forums of HP, I would be happy to help you! I understand that you have the printer set up on your network, but the software says that the device is not accessible. Sometimes the IPv6 may interfere with the connection, and I suggest we disable that before anything else. On the fornt of the printer Panel, scroll down to and then select Wireless. In the wireless Menu, select Advanced settings, then IPv6 and.

    Now we are going to let the router and unplug the power cable (NOTE: do not reset the router), then do the same with the printer and shut down the computer. After a minute, plug in the router, wait to fully turn on, then plug the printer back in and wait for the wireless light become solid. Once the router and the printer are on, go ahead and re - turn on the computer. This will refresh the network connection.

    Please let me know if this solves the problem by marking your post as solved (click on Accept as Solution button below). If the problem persists, let me know, I'll watch for your reply.

    See you soon!
