Initial Wireless Troubleshooting

Hi Folks
How we start initial Troubleshooting Wireless related  issues,we have WCS/WLC 4400 along with LWAPP?
thanks
Ibrahim

do you want to troubleshoot connectin between WLC to AP (i.e. AP join problem) or
client connectivity issue?
In general, you should use debug mac addr to limit the debug. Then, run debug capwap packet or debug client to troubleshoot AP join or client association problem.

  • Photosmart D110a Wireless Troubleshooting with D-Link DIR-655 and Mac OSX 10.8

    Good evening all,
    Apologizes if this has already been posted. I've googled this issue a couple of times, but I still haven't found a solution for this problem.
    I have the Photosmart D110a and I'm running Mac OSX Mountain Lion, and my router is a D-Link DIR-655 and my security is WPA-Personal and the router is running in 802.11gn mode. My ISP is Optimum Online.
    The issue that I've been having is that the printer works wireless when everything has been recently booted up. As does the scanner. However, if it hasnt been used for a while, the printer shows up in the OSX Print & Scan settings page as idle, but when I try to print, the dialog just says "looking for printer" and never finds it, and just says "The printer is not connected" under the item in the OSX Print Queue. Because of this, I have to restart the computer or restart the printer for them to find each other again. 
    I've seen other solutions on here, such as giving the printer a static IP address, and this hasn't worked either. The printer is still accessible with the static IP address, which means it's still got a connection to my network, but for some reason the OS isn't recognizing it or something. 
    It's obvious that the printer works when everything is freshly rebooted, but I still haven't been able to figure out this issue once it's been idle for a while.
    Any help would be greatly appreciated!!

    Hi,
    Try following my post below, I believe it might be relevant as the router drops the Bonjour connection:
    http://h30434.www3.hp.com/t5/Printer-Networking-and-Wireless/losing-connection-to-airprint-a-few-min...
    I would also suggest updating your router's firmware and check if that may help:

    For any help with this proccess I would highly recommend contacting Dlink support.

  • Wireless Troubleshooting Questions

    We have a Cisco 4400 WLC with about 70 Cisco AIR-1131AG-A-K9 access points.  The controller runs and the access points run 4.1.171.0 code. 
    We work in a hospital enviroment and nurses from one of our floors (3N) are complaining about poor/low signal when they enter a patient room with a mobile/nursing cart.  They say that the low signal strength really slows them/their medical applications (Meditech POM) and they are forced to move to a computer with an Ethernet connection to work.  They are then forced to basically communicate with the patient by yelling or move back in forth between the wired computer and the patient room.  The mobile/nursing carts are just specialized mobile workstations with a dell laptop and a battery backup. 
    The native Windows XP wireless management bit says that in one particular problem area we get about two bars and are connected at 11 mpbs.  I can set my dell laptop ontop of the mobile cart and while I more-or-less get the same signal strength my connection speed is faster.  We found that we were both connected to the same AP, but the slower device connected over the 802.11g and the faster device connected over 802.11a.
    I also know that each 802.11a radio only had between 1-3 clients associated with them, while our 802.11g radios each had between 3-8 clients associated with them.  We do not allow 802.11b, so I am not sure how to explain the difference in speed.  My guess is that it is due to the number of clients associated with the 802.11a radio vs the 802.11g radio, or am I am totally off?
    I think our biggest problem is the low signal strength in the patient rooms.  I unfortnately, did not document the RSSI in that room or even conduct any type of performance tests.  I think we spent too much time trying to blame the issue on some type of interference or rouge AP, but that didn't return anything.  We did have two of the three access points show that they failed the interference profile, but that seemed to have been transient.  What types of things should I do to determine if the signal strength is at fault or it is just the scape goat, futher more the only means of addressing the poort/low signal that I know of is by increasing the power level on the access points.  they are currently set to 1.  How much would you increase the signal to begin with?
    I added a AP placement map.  I indicated the location from which we tested with a blue dot.  Please let me know if I need to add or clarify anything.  Thank you all for any assistance or suggestions you can offer.

  • Macbook wont move past initial wireless setup

    I got my macbook yesterday and it started up with the welcome sequence, asked me to select languages and then asked to connect to a wireless setup
    I selected my router, put in the password and it said "configuring computer"... I thought it would take a moment, but 3 hours later it STILL read "configuring coumputer"

    I would recommend calling 1-800-My-APPLE and have a tech help you out. That will be the fastest way to resolve your problem.

  • C4580 wireless troubleshoot

    My current network setup:
    1x LINKSYS WRT310N wireless N router
    1x vista 32 bit connected to router via ethernet
    1x xp pro laptop connected to router via ethernet
    1x vista 32 bit laptop connected via wi fi
    1x vista 32 bit laptop conencted via wi fi
    Situation:
    On first run of installation, went smoothy with the two computers connected to the router via ethernet. Could successfully print wirelessly. However, on first attempt of installation on one of the wireless laptop, problems occured. At first, it could not automatically find the printer (the 2nd etherneted laptop could) through installation, I then had to manually enter the printer's IP. (At this point, i would like to point out that I had a COMODO firewall running at the same time of installation, but the firewall was set on installation mode. ) Things then we normal until installation appeared to have finish, however, my printer suddenly lost connection with my wireless laptop. I then checked the the previous etherneted computer, and both had lost connection with the printer as well. Twiddling with manual IP input did not help and i decided that during installation on the wireless laptop, it must of messed up the printer's settings. So I then uninstalled software off of all machine.
    On second uninstallation, things turned for the worst. On my etherneted PC, i encounted an error code "100 VSA" after the input of WEP kep for my network. I then chose to proceed with installation anyways. The result was that USB printing works, however, as soon as i unplug the USB, the printer loses connection with my etherneted PC. I also attempted to reinstall on my wireless laptop, but i then encountered an fatal error, something along the lines of "stub -wXXX" ( i cannot remenber exactly)
    Attempted fixes:
    restore to default network settings, and then reinstalling software
    enabled/disabled MAC filtering on router
    power resetted
    resseted all network devices
    Help would be greatley appreciated!
    This question was solved.
    View Solution.

    First, let's restore your network configuration to a known state:
    Turn off MAC filtering on the WRT310N.
    Turn off any static IP address you may have set in the WRT310N.
    I think you are using WEP to secure your network.  If so, what is the length of the key?  Does it contain only number and the letter A through F?
    Power cycle the C4580.
    Wait a minute and print the network configuration page from the C4580 and tell me the IP address.
    Verify that you can browse the internet from all computers.
    If the printer's IP address is of the form 192.168, then it may be on the network.  Tell me if you can access the printer's internal web page from your computers.

  • Wireless drivers will not work properly in Win XP

    Hi,
    I have a late 2007 white macbook and when I got the computer then I immediately installed Windows XP so I could have Microsoft Office. When I did so I installed the Boot Camp Drivers from the Mac instal disc 1. It worked fine for about a year, I don't use Windows much at all except for maybe powerpoint and for some reason the wireless internet stopped working.
    I've tried reinstalling and repairing the drivers to no avail. Some of them like the iSight camera work and the eject button/ right click with two fingers.
    The gray diamond for Boot Camp that used to appear in the windows toolbar (bottom right corner) does not load anymore. I'm not sure why not. that's probably the problem but I used the same install disc I used the first time (reinstalled them twice now) and this time it will not work completely.
    Windows XP wireless utility does not recognize the signal, when you click "refresh network list" nothing happens....it doesn't even search.
    Finally I tried installing the third party driver from Broadcom which has a wireless utility. this utility at least recognizes my network but cannot connect. the log for the utility just keeps saying:
    "Initializing Wireless State Machine"
    The network conects fie to OSX and the three windows computers in my house....there is no protection.
    Thanks for the help!

  • Can't Connect OfficeJet 7410 to new wireless network - used to work on old one

    Hi, I'm on a Mac OS.  I just upgraded my wireless network to use an airport extreme.  I have a verizon fios router - same as I had when it used to connect.  The only change was adding the airport extreme.  Now, the officejet 7410 all-in-one will not connect to the wireless connect.  It SEES the name of the network, and asks me for a WEP Key, which it didn't used to do.  It used to ask me for the network password.  I found the WEP key on the router and it acts like it is trying to connect but takes a long time and then gives me an error.  One time it never gave me an error and seemed like it had worked, but was not connected.  It just gave up. 
    My configuration page indicates offline with no active connection and wireless status disconnected.  
    I restarted everything with no change.  I don't know why it would be asking me for a WEP key this time and then not accept it but that was the first indication that something was different when it didn't ask me for the network password.
    Also, as a separate issue but related.  In trying to fix this, I deleted my drivers to reinstall and see if I started over that it would work.  That created another problem in that now it seems that HP no longer supports a driver for this printer.  Is that even possible?  It's not that old.  It says it does not exist on the software update.  Please help!

    Hi YSJA,
    I'm sorry to hear you've had problems accessing your Officejet 7410 since adding the AirPort Extreme to your home network.
    I have included a link to HP's Wireless Printing Center troubleshooting section. It has section, "Was anything changed or updated on your router recently?" that has detailed steps to help you resolve the issue.

  • New problem with wireless connection since 27th No...

    Main desktop computer (windows xp) is connected directly to the internet via ethernet cable to BTHub3. No problem exists with this  connection.
    We have previously had no problem connecting Tablet, laptop, and internet radio via wireless connection to our Hub. Problems now exist with wireless connection to all of these devices:-
    - When attempting to use any of the devices wirelessly, we are unable to obtain a connection to our Network (shown on the list of those available) - indicates -  "out of range" or "obtaining IP address" or "authenticating" or "network disabled - poor connection"
    - On occasions, the devices DO show that they are connected wirelessly but are unable to access the internet or use any programmes requiring an internet connection. Messages indicate - "no internet connection" or "connection timed out - retry" or "cannot access this webpage", even when we are in the same room as, and only a few feet away from the Hub.
    - One anomaly has occurred in that the internet radio did connect and function normally on 2 occasions recently , for a duration of a couple of hours, before loosing the connection. However, during this time, the other devices still refused to connect.
    Measures we have undertaken to try to resolve the problem are :-
    - We have visited the "Wireless troubleshooting" part of the BT Helpdesk on several occasions, but had already tried the measures suggested here, including changing channels and hub reset.
    - We have spoken at length to the BT tech. helpline who have been unable to resolve the problem.
    - We have emailed BT Help and received a reply from India suggesting all the things that we have already tried (ie. a "stock answer").
    - We are not confident enough to access the Hub Manager as we feel feel this is beyond our capability.
    We would be most grateful if someone could help us.
    Solved!
    Go to Solution.

    Wingman2, the first thing I would do is uninstall BTDesktop Help if you have it installed. It can cause more problems than it solves.
    I would also suggest that the first thing to try is a factory reset of the homehub by pressing a pin into the recess button on the rear for about 20 seconds.
    After you have done a reset if you still have problems, download, install and run inSSider. It will show you the wireless channels and which one your Homehub is on. You want to find the channel with the least congestion, ie. least number of users. Once you have that you need to change your homehub onto that channel.
    See link for insider. Use the free version.
    http://www.metageek.net/products/inssider/
    See link how to change channel on homehub
    http://bt.custhelp.com/app/answers/detail/a_id/14094
    After that if you are still having problems you could try setting the home hub to b/g only instead of b/g/n. If one of your devices is not "n" capable it could help.

  • Trouble Connecting Printer to my Wireless Network

    I cannot connect my HP Photosmart C4599  to my wireless network. When I try to access the URL for the EWS http://0.0.0.0/ (listed as the EWS on my network config page) , it says no data received, and hence I've hit a roadblock. I've visted the support page at http://h10025.www1.hp.com/ewfrf/wc/manualCategory?cc=us&dlc=en&lc=en&product=3757826& but still haven't resolved the issue. Please help, thanks!

    Hello @MikeDSF,
    Welcome to the HP Support Forums!
    I understand that you are experiencing issues when connecting your HP Photosmart C4599 All-in-One Printer wirelessly to your Mac OS X 10.9 Operating System. I would like to offer you my assistance with this. Now, support options are limited as you do not have a downloadable HP Full Feature Software and Driver for your HP Photosmart printer on the Mac OS X 10.9 operating system. Therefore, you will be relying on your Apple Updates to load the driver functionality of your printer on your computer. This also means that you cannot run the standard wireless setup that you will see under the HP Photosmart User Guide as you have no standard Wireless Setup utility without any HP Drivers. In saying that, the IP Address of all 0's is not valid. All 0's tells us that your printer is not on your wireless network at all. At least we have a nice clean slate to work with.
    Because your HP Photosmart has no HP Full Feature Software and Drivers on Mac OS X 10.9 the wireless setup is going to be very challenging, unless you have a computer that is using a supported Operating System. We could run the wireless setup on the supported Operating System and simply 'add' your printer into your Mac OS X 10.9 computer once the wireless is setup.
    Your printer is supported with HP Full Feature Software and Driver on Mac OS X 10.4 to Mac OS X 10.6. There are no HP Full Feature Drivers for Mac OS X 10.7, 10.8, 10.9, or 10.10.
    Your printer is also support with an HP Full Feature Software and Driver on Windows XP through to Windows 8.1.
    Please let me know if using a supported Operating System is an option just for the initial Wireless Setup. Once I know what option works best for you I will be able to provide additional support options. I look forward to hearing from you!

    I connected my Airport Express on my existing wirelle network.I have a wireless printer connected to this network. How can I use this printer?? only using USB??

    Hello @DoraMae,
    Welcome to the HP Support Forums!
    I understand that the wireless feature on your HP Photosmart 7520 e-All-in-One Printer does not appear to maintain a consistent connection. I would like to assist you today with resolving this connectivity issue. However, before I am able to provide you with accurate step-by-step support to resolve this issue I do need to know what Operating System you're using on your computer?
    In the meantime, can I have you click here to access the standard wireless troubleshooting steps. Once the support document opens please select your Operating System. Next, follow through the listed Solutions to resolve this connectivity issue.
    Please respond to this post with the result of your troubleshooting. Should the issue persist, be sure to include you exact Operating System in your response so I can easily guide you to a Solution. I look forward to hearing from you!

  • T61 Wireless Repeatedly Turns Off Windows Control

    Upgraded firmware in my wireless router, and now my T61 can't connect wirelessly.
    Wireless Network Connection is properly identified, Signal Strength is Excellent, speed is 54 Mbps. Status is Limited or no connectivity.
    Something keeps turning off my Wireless Zero Configuration Service. EIf I start it manually, and check off "Use Windoes to configure my wireless network setting,", I get wireless access back. But those actions get reversed when I reboot the computer.
    What can be causing this?
    In case it's relevant, the Lenovo PC Doctor 5 wireless troubleshooting test fails on the TCP/IP Network Connection Test, saying "Cannot Run". That happens even if I've gotten my wireless connection working.

    Hello,
    Have you tried upgrading the ThinkPad T61's wireless drivers as well?  If so, did that make any difference?
