  • Meraki wireless access point disconnects clients

    - by resolver101
    We have a Meraki MR16 Cloud Managed AP and it disconnects certain clients. The clients with Intel wireless cards work without any disconnects. The Meraki reports the follow in its event log: Sep 4 09:55:47 WPA authentication Sep 4 09:55:47 802.11 association channel: 11, rssi: 64 Sep 4 09:55:38 802.11 disassociation client has left AP Sep 4 09:55:38 WPA deauthentication vap: 0, radio: 0, aid: 1633956416 An example wireless network card which the Meraki disconnects is Realtek RTL8191SE 802.11b/g/n WiFi Adapter. The realtek laptop is sat 2 meters away from the AP and has a lot of signal and the Meraki reports minimal interference. Any ideas why it disconnects non-intel wireless network cards?

  • How to bridge multiple wireless access points (and internet entry points) into one network

    - by amccormack
    I have two DSL lines coming in to wireless access points and then running to a RV082 Gateway/Bridge. The gateway then runs to a switch, which runs to multiple PCs and a Printer (See picture below). Normally, I would set up the wireless access points behind the gateway, but they are also the modems for the dsl. I have found that I can not print to the network printer if I am connected to the wireless network, but only if I am connected to the wired network. How can I configure the Gateway and APs (Routers) so that the PCs and Printer are all on the same internal network? I have tried turning DHCP off or redirect on the APs and redirect them to the Gateway. However, neither of these worked. Furthermore, I tried pinging the Gateway from the AP but got no response.

  • Refresh devices - reconnect CF card drive by script (unplug-plug equivalent)

    - by Chris
    Hello I plug a completely clean CF-card into my USB card-writer. Then I dd a mbr block of 512 bytes size to the device, which contains the partition table and the definition of one partition. Problem: While "fdisk -l /dev/sdx" correctly displays the partition, it happens that there is no device like "/dev/sdx1" after these operations (as it was not present before). Unplugging and plugging the card-writer solves the problem and makes the device(s) appear. Since I use this procedure in a script, manually unplugging and re-plugging is no option whatsoever. Is there a way to "refresh" the devices or to "unplug and re-plug" the drive by script such that /dev/sdx1 appears? Thanks for any help, Chris

  • MacPro 1,1 video's card

    - by alexus
    I just bought a Mac Pro 1,1 from my coworkers and I'm looking to upgrade video card as the one inside is very noisy. What are my options? Basically I'm not looking to spend a lot of money, in fact i'd rather to spend as little as possible and get low end or mid range card, I'm not really playing games all that much so pretty much anything will do, I'd prefer 2xx series though. Current Mac Pro sells w/ GT120, Apple sells upgrade kit for $149 (which is okay, I just not sure if I'll be able to use this card on such an old Mac Pro)

  • Buying Video Card for 1600x900 monitor?

    - by Yar
    I just bought a monitor for a relative's computer (Intel 82915G chipset) which should produce 1600x900. Though the current card can produce 1600x1200, there's no way (that I know of) to force it to produce 1600x900. Assuming buying a card would be a solution, how would one find a cheap video card that can do 1600x900? They don't seem to list the modes in most ads. If I'm missing something in Windows, please let me know, but I've looked around quite a bit and tried many things (including unsupported resolutions, etc).

  • Recommendation for PCI SATA addon card?

    - by edmicman
    I have a couple of dead PCs from my wife's office that have working SATA HDDs. Sorry, I don't know if they're SATA I or II, just that they're SATA. Unfortunately, all my spare hardware at home is pretty old; all I have is IDE support. I was thinking I could get a PCI addon card on the cheap that would support SATA and put together a budget server of sorts to play with and be able to use those drives. So I've got a couple questions: After some searching it looks like I can get an addon card for ~20 bucks, but it looks like they're all SATA I? Would that matter? It looks like going to SATAII bumps the price up to $40-$60 or so. Are there any recommendations on a card to get?

  • How to go about scheduling a task in windows 7 to change wireless connection

    - by Skindeep2366
    This may or not be something that can be done. I cannot find anything on the wireless connection manager built into windows 7 let alone methods for passing params into it. Problem is as follows: I have 2 wireless routers. One provides internet access, the other provides sole access to the local network. Every day at 4am the main system creates a backup in 2 locations. One is a External usb drive, the other is a location on the network. This is all cool if it is remembered to change over to the local network router before leaving. But if it is forgotten the roof will collapse, the walls will burn, and I will be... well you get the idea. Solution: there is already a custom event that fires a automated backup program at 4am everyday. I need someway to force the wireless network to use the correct connection at say 3:58am everyday. Any ideas????

  • Open source system for swipe card access?

    - by Moduspwnens
    We're looking at replacing our campus-wide magnetic swipe card system with something more robust. The "programmer" side of me says there's got to be an open-source, scalable solution that already does this, but all I've been able to find are proprietary vendor-specific solutions. Ideally, it'd have the following: Based on some open standard that allows us to select from a wide selection of card readers (like IMAP or HTTP) Support different kinds of card access (magnetic strip, RFIDs, etc.) Future-proof (to the extent possible) The lack of information I'm finding leads me to believe I'm not searching for the right things... or such a solution doesn't exist. Is there not some basic, open-source solution to this (like MySQL for databases, or Moodle for an LMS, or Apache for a web server)?

  • New video card? [closed]

    - by TutorialPoint
    I ran into some problems with my ATI Radeon x1200. I want it to support vertex shader 3.0, but it only does 2.0. This is because Call of Duty: Modern Warfare 2 only works with 3.0. So, I want a new video card. Can someone help me, with a more clean look to it? I bet if I would stick to some seller, I would end up with a video card that does not support what I want, or is too expansive. I really do not want it to be above $75, if possible. Some info about my PC: Manufacter: XXODD Processor: AMD Athlon64 X2 DualCore 4000+ 2Ghz (but running currently 32 bit OS) ATI Radeon X1200 video card (the problem) 1 GB RAM DDR2 MS-7367 Motherboard Windows 7 Ultimate OS 32-Bit Build 7600 RTM

  • ID Card printers and software

    - by Chris
    My company of about 60 people currently uses a Magicard Pronto ID Card printer and the Magicard ID card software. The printer is would be OK (not great) if they released 64 bit drivers for it, but Magicard ID is without a doubt one of the worst pieces of software I have ever used, ever. It would be OK for occasional hiring, but my company is looking to add a lot of people rather quickly. Does anybody know of decent ID-card printing software, and possibly a replacement printer? I might just "accidentally" run over this one with my truck a few times.

  • Enable/disable wireless interface in a bat file

    - by Herms
    Is there a way to enable/disable a wireless network interface via the command line (so I can put it in a bat file)? When I'm in the office I use a wired connection, but Windows still occasionally bugs me about my wireless connection not being connected (even though I turned off the option for notifying me when there's no connectivity). I'm guessing the only way to stop it from bugging me is to disable the interface, but I'd rather not have to go into the network settings every time I need to do so. I'd like to set up a bat file or a shortcut that I can use to enable/disable the wireless (preferably a single one that toggles the current state), and then just set up a keyboard shortcut for that. I just have no idea how to do so from the command line.

  • Using a CF card as an IDE HDD

    - by dartacus
    I have an old Sony laptop (Vaio TR1-MP) that I like. The HDD has died and since it's a hard-to-find 1.8" IDE hard drive I'm considering buying one of those little CF card adaptors and a 16gb CF card. The total cost of that is about £30 and replacement HDDs for this model are far pricier. Has anyone replaced their HDD with a CF card in this way, and, crucially, is the performance utterly horrible afterwards? ;-) I've seen a couple of threads which hint it's possible but the advice eventually given was just to buy a SSD, but I'm not even sure if its possible to get a 1.8" SSD with an IDE connector that'll fit my laptop. (I freely admit that the most sensible thing to do would be to bin it and just buy a cheap netbook which would be smaller, faster and lighter than the sony, but it does have a very nice widescreen display and dammit I just like it !) Thanks, G

  • Cannot install wireless lan service on windows 2012 RTM offline

    - by user1763118
    I'm having trouble installing the wireless lan service offline with a fresh installed windows 2012 server RTM. I tried "install-windowsfeature wireless-networking" in the non-gui mode and using the server manager in the gui mode to enable the wireless lan service, but both of them show a "failure configuring windows updates" message after the installation restarted the system. I checked the event log and I think messages about "The WLAN Autoconfig service depends on the following service: nativewifip. This service might not be installed" are the source of the issue. Google shows it is a service called "native wifi filter", but I cannot find anywhere to install that service. I don't have a Ethernet adapter for that computer, so have to install everything offline before the wifi's working.

  • When RDP as a Domain User, Smart Card Requested

    - by Paul
    My W8 machine is connected to domain zen. If I rdp to the W8 machine, I can log in as a local user without problems. If I try to log in as a domain user, I am prompted for a smart card instead of a password. Any ideas why? Note that Interactive login: require smart card is disabled in group policy: And here is the output from rsop.msc: Some additional information on this one. If my connecting machine is on the same domain/network as the W8 machine, then I am prompted for a password as usual. If the machine is remote, on a different domain, then I am prompted for a smart card. In addition, the machine I am connecting from that gets the smartcard prompt is an XP box. I haven't isolated exactly which of these factors triggers the different response.

  • DELL U2410 Monitor(Display Port) & Graphic card

    - by Anj
    I was looking for a 24" monitor and bought the Dell 24" inch ultra sharp monitor which has DisplayPort( new keyword for me) seems it is equivalent to HDMI. Now I would like to enhance the display capabilities for my laptop and desktop(both have VGA output as of now). Couple of questions in mind: Is there a single HD graphic card which i could use for both desktop and laptop? I understand it has to be external but if its costly then I would stick on internal graphic card for my desktop. Please recommend external if its cost effective else I would go for internal one(Budget is around $70 or Rs 4000. Is there a HD card which I could use for both HD video and 5.1 channel audio output? I generally use the computer for office work/ listening music and watching movies, not gaming.

  • TV Card Problem

    - by MladenB
    I have DVB-T card (CE9500B1) and it doesn't work. I've tried everything I knew (but I don't know much). It doesn't show any problem, but shows "No Signal". I used another TV card USB, found channels, put mine card again, and again nothing. I don't think it's broken, when I put USB in my laptop, it recognizes it. Also, these little lights on USB are never turned on. OS is Win 7. Help, please.

  • Driver denied access to PCI card

    - by Corin
    We wrote a Windows device driver to access our custom PCI card. The driver uses CreateFile to get a handle to the card. We recently had trouble at one installation were the card appeared to stop working. We tried replacing the card (the replacement appeared not work either). The computer vendor replaced the motherboard and both cards still failed to work. We put the cards in a different computer and both worked fine. We now have the computer at our office for examination. The Windows Device Manager lists our card in Other Devices as usual and says it's working fine. However, our driver initialization fails when it attempts to connect to the card. We created a test version of our driver with some extra debugging and determined that CreateFile is failing. It returns INVALID_HANDLE_VALUE as it is supposed to on failure. GetLastError indicates the error is Access is Denied. Since we're logged into the system as a local administrator, what can deny access to the device?

  • How to Add a Business Card Image to a Signature in Outlook 2013 Without the vCard (.vcf) File

    - by Lori Kaufman
    When you add a business card to a signature, an image of the business card is inserted into the signature and the vCard (.vcf) file is attached. If you don’t want to attach the vCard file, you can insert the image only into your signature. To insert only the image of your business card without the .vcf file, click People on the Navigation Bar at the bottom of the Outlook window. To get a business card image we can use, we must view the contacts in any form other than People, so we can open the full contact editing window. To do this, click on a different view in the Current View section of the Home tab. We chose to view our contacts in the Business Card format. Double-click on your contact in the current view. The full contact editing window displays with an image of the business card on the right. Right-click on the business card image and select Copy Image from the popup menu. To close the contact editing window, click the File tab and click Close in the menu list on the left. NOTE: You can also click the X in the upper, right corner of the contact editing window to close it. To open the signature editor, click the File tab. Click Options in the menu list on the left side of the Account Information screen. On the Outlook Options dialog box, click Mail in the list of options on the left side of the dialog box. On the Mail screen, click Signatures in the Compose messages section. NOTE: You can also access the Signatures and Stationery dialog box from the Message window for new emails and drafts. Click New Email on the Home tab or double-click an email in the Drafts folder to access the Message window. For more information, see our article about assigning a default signature. In the signature editor, right-click and select Paste from the popup menu. The image is inserted into the signature. You can also use this method to copy a business card image for use in other documents and programs. It’s also possible to insert the vCard (.vcf) file into a signature without the image. We’ll cover that topic tomorrow.

  • How can I get a Belkin N600 DB (F9L1101v1) to work on Ubuntu 12,04 64-Bit

    - by rheide
    I could use some assistance to trying to get a Belkin N600 DB Wireless Dual-Band USB Adapter to work on a Dell Inspiron 1525 with 64-Bit Ubuntu 12.04. The device won't work out of the box. Tried to go the NDISWrapper route, but using the GUI, received the following message: Module could not be loaded. Error was: FATAL: Module ndiswrapper not found. Is the ndiswrapper module installed? Despite the fact that it showed up listed in the GUI, the device still did not function properly. How should I proceed from here?

  • wpa_supplicant ioctl[SIOCSIWENCODEEXT]: Invalid argument

    - by RobinJ
    I just installed Ubuntu Server on a spare computer with a broken graphic card, and I needed to setup my wifi. I thought No problem, I've done it before from the command line, in Arch Linux., only the steps I had to take in Arch Linux didn't work in Ubuntu Server (that's odd, wasn't Ubuntu supposed to be so much more user-friendly? :/). This is what I'd normally do: ip link set wlan0 up wpa_passphrase <ESSID> <WPA KEY> > /etc/wpa_supplicant.conf wpa_supplicant -B -Dwext -i wlan0 -c /etc/wpa_supplicant.conf dhcpcd wlan0 Only at the wpa_supplicant I get some strane message: ioctl[SIOCSIWENCODEEXT]: Invalid argument ioctl[SIOCSIWENCODEEXT]: Invalid argument And if I try to run dhcpcd then (which I manually installed, as it didn't come preinstalled with Ubuntu Server), it times out. Help on how to do it would be much appreciated. My wireless driver is iwl3945.

  • How to set wifi driver settings to prefer 5 GHz channel above 2.4 GHz

    - by Wouter
    Currently I'm in a new building of my university. In this building my wifi often breaks down and then restores connection again. This is really irritating since it happens a lot. Now as a coincidence there were some tech guys running around here and where asking everyone if the wifi was doing fine. I told them that my wifi tears down all the time and then reconnects. They figured out that my wifi is switching all the time between the 2.4 GHz channel and 5 GHz channel. They asked me if I could acces the driver settings of my wireless card. Unfortunately I don't know how to do this is in either Linux or Windows. And unfortunately again they only knew the windows solution xD. So I hope somebody can tell me how I tell my wifi that it should stay on the 5 GHz network and not disconnect and switch to the 2.4 GHz channel?

  • Unity GUI pauses/freezes for less than a few seconds

    - by Ahmad Nassri
    I've just got my new Lenovo ThinkPad X220 with Intel HD graphics (I'm not sure what the chip is) and I've installed Natty. Everything works great out of the box, except there are short pauses/freezes in the UI that randomly occur, they last less than 2 seconds, actions are still taking place in the background (like typing) when the UI un-freezes I can see the characters I've typed, the app I've clicked, loaded . I can confirm that this is only happening with the new Natty 3D interface, I've tried 2D and the classic interface and there were no issues. Googling this topic seems challenging as I can't relate the problem in keywords. And I keep getting results relating to full GUI freeze which I don't have. This is troubling since I have Natty 3D running on older machines without any issues . I wonder if anybody else have experienced this or came across this issue before. Thanks.

  • Turn-based Strategy Loop

    - by Djentleman
    I'm working on a strategy game. It's turn-based and card-based (think Dominion-style), done in a client, with eventual AI in the works. I've already implemented almost all of the game logic (methods for calculations and suchlike) and I'm starting to work on the actual game loop. What is the "best" way to implement a game loop in such a game? Should I use a simple "while gameActive" loop that keeps running until gameActive is False, with sections that wait for player input? Or should it be managed through the UI with player actions determining what happens and when? Any help is appreciated. I'm doing it in Python (for now at least) to get my Python skills up a bit, although the language shouldn't matter for this question.
