Wi-fi/lan connection only works on some devices

Hello... I have problem with wi-fi/lan connection. I work in a school with about 100 children. The problem is that some computers/phones/laptops can connect normally to a connection wi-fi/lan but some cant. The internet icon actually shows normal connection, but you cannot browse the internet. When this happen the only thing I can do to help temporarily change the mac address of the device with software changing Mac and which usually resolves it. So maybe the problem is that too many devices are connected at the same time or mac addreses interfere with each other or something. I have tried almost everytnig, reseting routers, change the settings of the router, changing channels, etc. of mac filtering... It was working fine before. Maybe you can help. P.S. Sorry for my bad English :)

  • LAN Connection stopped working on my computer running WIN XP MEDIA CENTER

    My LAN connection stopped working on my WIN XP MEDIA CENTER-based computer. I have access to the internet with optimum online. I have a router connected to my cable modem (US Robotics) wireless and desktop with the functioning of the wired connection stopped. My wireless connection on my laptop works very well on the same network. I first stop the modem, router, computer and re started at all. Modem Router 1 2nd, then on computer. Usually works, but not this time. Contacted optimum online and went through some procedures to correct the problem. Open cmd prompt, ping tried only to get 3 of any answers and 1 reply. Tried ipconfg / renew, did not work.  Firewall had closed during all of this. Service representative from optimum online said that he could see my modem was working but something like a firewall was blocking my computer access. Tried ipconfig/all and gave him the ip address he asked which showed, 169.254.80.196, he said that address will not work and we continued trying to renew the ip address, and we could achieve.

    Now I mention here that this problem occurred when I had a power surge while I was online. I rebooted and this is the problem that I was. I asked the rep optimal online what else could be the cause as a virus or damaged surge my LAN or OS and he said for me to try to get in touch with microsoft and perhapse they could help me more. I hope someone has an answer for me.

    Please... Help!

    Thank you

    Don Soutar

    Watch 169.254.x.x IP address only:

    • The connection to the LAN is configured to obtain an IP address automatically, and:
    • He cannot communicate with your router to get the address.

    The surge may have damaged the computer's Ethernet card.  If so, replacing it with a new adapter will fix the problem.

  • Form with active user rights only works on some machines.

    I created a pdf file that contains video media. For this I have attached an acrobat form created with extended user rights. When send a certain number of respondents, some are able to open and fill out the form, and then return the form (in pdf format) while others experience a message "this operation is not allowed.

    The pdf of media is created in Acrobat 9 pro on the Windows XP platform and the form in Acrobat as well. The form has three drop-down menus and the three fields to fill.

    If the form is sent on its own, everyone is able to access.  It is only when the form is sent as an attachment to the pdf of video media that this is a known issue. The pdf file must be retro-compatible with Acro7.

    My problem is that I do not understand why it works with some and not others. (These are not coprorates but people.)

    You will appreciate the help. Date deadline has passed.

    For use with Acrobat you don't need extended Forms user rights.

  • Scanner only works on some computers

    I recently bought a Canon LiDE 220 scanner which is supported by El Capitan according to apple of supported scanners page, but whenever I try to scan on my computer it says "Scanner reported an error. Cannot communicate with scanner ". I installed the Canon software before you try to analyze, and I wonder if that's a problem because it works on two MacBook Pro (Non-retina display) without the Canon software. I restored my computer from a time machine backup I made before I installed the software, and I still had no luck. Any ideas?

    So in summary:

    Does not work on MacBook Pro (Retina Display) OS X El Captain with or without software and drivers from Canon.

    Does it work on MacBook Pro OS X El Captian without Canon software.

    I tried to use a snippet, page printers and preferences system, Capture of Image Scanners and scanner Canon proprietary application all to nothing done.

    Has anyone run into this or know why it works on some computers, but not mine? I love a fix or work around.

    Thanks in advance

    Hello Mos Fett,

  • sharing is only working for some websites of Internet connection

    Wi - Fi my laptop is steady as a rock, but the wireless adapter I have for my office to cancel very often, so I decided to connect both via an ethernet cable and use internet connection sharing so that the Office can enjoy wireless laptop. Both computers have Windows 7 Home Premium installed.

    The Installer seems to work, but only for some Web sites - for example, it has no problem to connect to google and microsoft.com using ICS, but he absolutely refuses to connect to facebook but also many other Web sites. My laptop has no problem connecting to websites that my office cannot connect, so I'm puzzled as to why it seems to be able to relay connecting to some Web sites, but not others. Can someone help me understand what is happening here, so that I can access more than just pieces of the internet on my desktop?

    I'm sorry, but you can understand how annoying it can be when someone does not even time to read your question and posts nothing but completely irrelevant, canned solutions (who would would realize that they were not relevant if they had taken the time to read it instead of just copy - paste * based on the title of the post). It's worse than no help at all, because then people who might bring if not actually useful assistance will see oh, "this question has already been answered" and move to one that was not. In any case, I'll try to ask in this forum. Thanks for the suggestion.

  • Satellite C660 - 115 WLan connection only works when the power cable is connected

    Hello

    A few weeks ago, I bought a Satellite C660-115. I want to surf the internet anywhere in my house without any son/cables.
    On the first day, I had this problem: when I disconnect _power_ cable, the wireless connection will stop working.

    The Web page on my screen will always be there, but a new page loading is a problem.
    It is sometimes useful to recharge (by pressing F5), - sometimes not. It is always useful to "ip address of repair", but not for long.

    The only solution is to atach regardless of how much power the battery has still the power cord.
    When I do, it is no problem whith the connection at all.
    I went back to the store where I bought it, they related to their own wireless network and they have had the same problem after a few minutes. In the shop too attach the power cable solved the problem.

    So the problem must be in my lap top, not in my network (modem or almost).

    Doesn't this all seem familiar, and if so, how can I solve this?

    I hope that my English is understandable, I live in Holland.
    Thanks in advance!

  • Create Bluetooth earpiece function only works in some cases

    The function create a listener Bluetooth generates an ID of listener that lets wait for an incoming connection of Bluetooth. Because every time that you run a VI that contains this function, it must create a new listener ID, otherwise the block following that wait on the listener will crash.

    I found that for the listener to create function work properly the entry that the Service Description must be connected to a control element. If its connected to a constant run only once, then creating a new id of the listener, but she keep this id indefinitely. In this case, you will need to close all the screws and reopen to be able to run the function again.

    (See attached VI for an example.)

    Can someone tell me, why is this? Is there a difference in the compilation/execution screw using controls instead of constants?

    Thank you!

    I could reproduce the error. I presented a report to R & D. I'll let you know when I get a response from them.

    For now, you can try using a control instead of a constant and make it invisible in the façade.

    Kind regards

  • DateTime liquid switch only works on some browser form input fields

    I have a form of agreement where I would like to have the current date is displayed only (readonly) in the form of entry.  This will display the date perfectly well a range of browsers and OS but my client always reports that the form field displays the date + time (22-June-2015-12:00). Apparently, it still shows 12:00 for the time. I was unable to reproduce it in any of my tests with several browsers and operating systems.

    That's what I wrote to add the date:

    {% assign dateVariable = {{globals.site.dateNow | date}} %}}

    < b >

    < td >

    Must I add another filter to indicate to the server does not add a time in there? Or maybe add some Javascript for him say look for a while and remove it?

    Any help would be much appreciated.

    It's weird.

    It will not be something to do with the browser because liquid is script server-side and today's date is server only side not the client side too.

    | date displays only the date but not the time, and I did not add time.

    I do not notice on your input field you after the aaaa: a dashboard - that needs to go just in case where but I don't think it would be. You need javascript.

  • Intel 3945ABG wireless connection only works for a Windows profile

    I have an Inspiron E1705 with Intel 3945ABG WiFi and my Windows user profile it keeps me gives error msgs. On the other profile in Windows, it works fine. The first problem I had was when I started once I got an error saying that Intel wireless has been updated of the profiles, please wait.

Now, if I use Windows to control the connection I can connect, but whenever I try to open the Intel PROSet / Wireless, I get: Intel framework MFC Application has encountered a problem and needs to close. We are sorry for the inconvenience. I also received a msg saying that zcfgsvc has a problem as well. I downloaded the latest driver, but which is not good. Is it possible to get just a new installation of the software? or would even help? I don't know that I have a disc with which, since that it is pre-loaded from Dell. Please help me, it drives me crazy!

  • Record mic using SampleDataEvent only works on some computers.

    I did a swf file that records your microphone and allows you to read.  I load the soundBytes in a float and re-read the float.  It works fine on the computer, that I developed it on (in IE, Chrome and Firefox).  It does not work on my second laptop.  And a few people in some forums have said that is not no longer works.

    Here is the file.  http://www.buttonbeats.com/images/MicCapture.html

    Here's the code.  I need some plugins in addition to the flashplayer?

    micRec.addEventListener (MouseEvent.CLICK, recordMic);

    function recordMic(event:MouseEvent) {}
    micRec.x = - 250;
    stopRecord.x = 0;
    const DELAY_LENGTH:int = 4000;


    var mic:Microphone = Microphone.getMicrophone ();
    mic.setSilenceLevel (0, DELAY_LENGTH);
    MIC.gain = 80;
    MIC.rate = 40;

  • FMS3 localhost connection only works

    I have seen a lot of topics with somewhat the same title and number, but have yet to find a solution. I'll you give as much information and if anyone can help it would be appreciated. I installed Flash Media Server 3 on a Windows Server 2003 developers edition. I've set up a simple project that has the following code:

    "" Head< script type = "text/javascript" language = "javascript" src = " http:// < server_ip > /flash/swfobject.js" > < /script & gt;
    Body< div id = "videocontent" > this content requires Flash and Javascript enabled. "" < a href = " http://www.adobe.com/products/flashplayer/" target = "_blank" > download the latest Flash Player < /a > < / div >

    < script type = "text/javascript" >
    var so = new SWFObject (" http:// < server_ip > /flash/mediaplayer.swf", "player", "555", "335", "8");

    so.addVariable ("file", "rtmp: / / < server_ip > /Vod/");
    so.addVariable ('id', '02_Alt_DB_Bi_Curls');
    so.addVariable ("backcolor", "0 x 262626");
    so.addVariable ("frontcolor', '0xffffff');
    so.addVariable ("image", "' http://10.1.1.1/images/stories/images/personal_trainer.jpg ' ");
    so.addParam ("allowfullscreen", "false");
    so.addParam ("scale", "noscale");

    so.addVariable ("autoplay", "false");

    so. Write ("videocontent");

    < /script >

    The player can be found here ( http://www.jeroenwijering.com/?item=JW_FLV_Player). anyway, when I connect via Firefox or IE on the localhost, video playback and the server registers a connection. When you connect to any other host that is not the local host, it will display will show the circle of progress and nothing happens. In the server, it shows the server connects but then instantly disconnects and the server connect it simply shows that disconnects the connected host, no message of. If you need more information let me know, I will try to provide.

    Thank you

    Video works sometimes on YouTube, not at all on most of the other sites.

    Audio player not working do not at all. Not yet visible or Real Player downloads against playing within the application like Amazon.

    Just as there should be in Internet Explorer.

    On my WordPress site has MP3 audio files and uses a flashplayer to view and play music files. With flash player on, nothing appears, (Bank space where audio player would normally displayed)

    If I turn off the flash of the shock wave, a text link that Downloads MP3 in a new window (quick player), also video does not work on any Web site. If I turn off the Flash and quicktime, text link to downloads of audio file in realplayer.

    Thank you. I uninstalled Flash 11.3 and installed the old version, 10.3. Everything works fine now. I don't know if it is a problem of Mozilla or Adobe, but it seems strange that either would such a problem of incompatibility to exist.
