Problems with the WLAN configuration

I can connect my raspberry using PuTTY on a static IP, but it does not work using WLAN.

WLAN using my router sees a device no is not an IP address, which I suppose Raspberry.

I guess that the tutorial is wrong, as it provides the same IP for the eth0 and wlan0, and it does not show the 'network' line in the section wlan0.

Or I do something wrong?

Here is the final solution to my problems. At the same time, there had been several configuration errors:

  1. I provided the two devices, eth0 and wlan0, the same IP address, as has been requested by the guidelines of Tom. Of course, this won't work. I had to provide separate IP addresses as @stainsb correctly pointed.
  2. My router was set to "isolate the wlan" which means that wlan is routed to the internet but not lan. Certainly to be able to communicate between lan and wlan, there must be no insulation. So I dropped this security feature.
  3. My router was set to "restrict the mac addresses" which means that only devices can connect to WiFi. Of course, I had to relax this restriction by adding the MAC of the WiFi dongle to the list of allowed devices.

With this three changes I use eth0 and wlan0 successfully at the same time!

BTW, it was not necessary or use wpa pairwise or wpa-group, as suggested by @khooke_acn.

Thanks to all and sorry for bothering with my stupid administrative problems!

  • Satellite U300-13U - iTunes has detected a problem with the audio configuration

    Please can someone help me? I have a laptop U300-13U and that you have installed iTunes on it. However, when I open iTunes I get an error message saying 'iTunes has detected a problem with the audio configuration and may not play correctly' which is an understatement - it does not at all!

    I uninstalled, reinstalled iTunes and Quicktime, but in vain. I have searched and exhausted the iTunes support boards but have nowhere either. The sound is fine as I can read CDs with no problems at all. The only suggestion I can get is that there may be a problem with the audio device magnet is not Apple and vice versa.

    Does anyone have AN idea at all as to what might be going on here? I'm completely out of my depth, I'm just a simple girl who wants to play his music!

    Thank you so much.

    Hello

    I don t use iTunes so I m not an expert player but first of all, you must give us some important information:
    -What operating system do you use?
    -Are you using the factory settings (Toshiba Recovery disk) or your own version of Windows
    -Do you have the yellow exclamation marks in Device Manager?

    OK, iTunes says that there is an audio configuration problem so do you trying to update the audio driver? If this isn't the case, you should try it.
    See the Web from Toshiba site for an update and see what happens. Then validate your result:

  • What is the problem with the BizTalk configuration tool?

    I just installed BizTalk Server 2010 (developer edition) and I restarted my computer, but the Configuration tool will not charge. Instead of loading the configuration tool, a dialog box displays saying "another instance of this program is already running" with the title saying "error". I am sure that no other instances of the configuration tool are already running. What's not here? If anyone can help me, that would be greatly appreciated.

  • Problem with the new configuration of the computer

    Hello. Read some guidelines for the installation disc in a new PC and I would like to ask for your help with my setup:

    My PC is msi x99a sli + i75820k, 32 GB of ram, msi gtx970, I use the CS6 version

    The problem is with the installation of drive: Samsung 950 pro ssd 512 GB, the SSD ultra more than 256 Sandisk, Toshiba 3 to dt01aca300

    The Sandisk SSD will be my OS, programs + pagefile

    The thing is: raw material should stay on the slower toshiba or should I put it with projects and media on the fastest ssd cache?

    The default location for them being on a SATA III SSD, I just leave them in the default location on the boot drive in the users folder.  Since they regenerate if necessary there is no reason to check them, just delete the every once in a while

  • Hanging Hyperion Distributed Environment to VM - problems with the DB configuration

    I prepared our torches and pitchforks to March at Redwood Shores, on this

    OK here you go, we are on a distributed environment three box, Oracle EPM 11.1.2.1, Windows 2008 SP2 (not R2) with databases SQL 2005 SP2

    We try to go to a virtual machine environment that is Windows 2008 R2, Sp1, SQL 2008 SP1 (I think on the SP) (even distributed structure, 3 images for essbase, for a web-EN of the report)

    We take a picture of our production to be applied in the VM, upgrade and secure DBs to 2008 and try to run the Setup.

    Sometimes we are bombing in various areas, that the services do not start, missing components, configuration failed, you name it.

    Someone had as much heartburn the transfer of an image of a box of existing production to another box?

    JTS

    OK so we just got the phone with Oracle and they are not favorite images-clapping fans either and were impressed that we got the system at least partially upwards.  Fine support oracle mode, we asked what is causing the conflict which we got the answer "I don't know".

    why we went this route is because during our dev environment set up, we had a horrible time migrate all Bishop calc (11.1.2.1 to 11.1.2.2) business rules so that we wanted to avoid this problem

    We will build from scratch on the new environments but want to build to 11.1.2.2 and migrate BRs, but do not find effective and smooth.  So we will probably build 11.1.2.1, download our existing applications, then migrate to 11.1.2.2 then migrate BRs

    If you have a better way to migrate the BRs I'm all ears

  • Problem with the Audio Configuration

    All of a sudden, I can't play Itunes, Windows Media Player, bec.of this audio configuration problem. I prefer not to take it to get fixed, can get expensive. Anything I can try/do, before having to take in? I have zero noise, my speakers don't work either, for no apparent reason...

    Hi nan18,.

    You could check in the Device Manager; Make right click on my computer then left-click on Properties, and then click the hardware and Device Manager.  Check if there is no yellow exclamations next to all audio devices, if there is then try to uninstall all the drivers sound card first to the Add / Remove Programs, restart your system and then reinstall the audio drivers. You need to restart your system to see if your audio works again.

    The problem you are experiencing may have been caused by an infection, but may also be due to a failure / interrupted the update of Windows.

    In some cases, that I've been able to solve the type of problem you encounter in doing a complete reinstallation of Windows XP, but this is a last resort!

    Let me know how it goes anyway.

    Well, I have a problem when a change to an alert (this would activate when free disk space is less than 10%), when the percentage of free space is 83% alarm color is red.

    I am doing wrong?

    You do not have something wrong. The red color is something that we felt as unhealthy. It's natural behavior.

  • Mac Air 1.3 Ghz i5, 4 GB ram end of 2013 everyone upgraded to El Capitan with the same configuration?

    would appreciate an answer from people already have the upgrade.problems with the same configuration? slower?

    FWIW, the El Capitan applications are no different from Yosemite. In fact, it is easier on resources in some areas. The main thing you need to worry is to make sure the software and equipment to use is compatible. Make sure you have a good backup in case you change your mind and want to downgrade.

  • There might be a problem with the configuration of your DOMAIN NAME SERVER

    Last week one, I noticed some problems with my internet connection. I have a BSNL broadband connection. I am connected to the internet, and after some time all of a sudden, I'm not able to connect. My modem lights are all on and on my laptop, I see the symbol of 2 computers with a note on it, which means that I'm connected. But still the pages not displayed. When I run Network Diagnostics (I Windown Vista) I get the error message saying: "there could be a problem with the configuration of your DOMAIN NAME server. I turned off the computer and the modem and switch it on after a long time... He would return but loses the connection with the same error message again. What can I do? I tried to reset the modem, also tried the system restore. What can I do? Please help me. I have laptop Dell Insipiron with Windows Vista and I connect wireless.

    We do not know how your system should be set up - including the DNS configuration and settings.  I recommend you contact your ISP's technical support group and get help from them in the configuration of your computer (and test lines and modem - the problem could be the modem and not on the computer or it could even be the service provider itself).  It can be something as simple as a typo or a box checked or not checked - I do not know because I do not know their settings (different for each access provider).  Give them a call.  I do so often when I have connection problems, and they are almost always useful, or schedule a service call if they cannot help.  I think it's your best chance to solve this problem.

    I hope this helps.

  • problem with the connectivity of customers after mixing several models with WLC 5508 Setup WLAN ap

    Hello

    I have 2 5508 wlc and AP 1130 and 1200 in my test harness.

    Currently, WLAN set is in place and works very well but the customer become a frequent problem with the power of the weak signal same AP is installed very near the place of the customer.

    I have my doubts, if I have a question because I use several models of AP in my set-up?

    How to rectify the same question?

    Some time customer gets limited connectivity, means that they usually get IP also.

    What are all the parameters to check in WLC?

    (1) very difficult for a person on a forum to respond. Check if your AAA server was indeed seen as inactive at the same time for other devices.

    If this is not the case, check the network connectivity between the 2. Maybe packets are lost between wlc and aaa server...

    (2) as I mentioned, it may have nothing to do with clent near or far from the AP. What happens if your DHCP server is not responding to the client? What happens if the dhcp request never reaches the level of the DHCP server for some reason any?

    You must investigate all along path to find out why the customer is not getting an ip address.

    Troubleshooting involves trace of sniffer, debug, client, etc...
