  • afp/smb transfers caps at 2 megabytes/sec, wireless N

    - by RD.
    I wanted to transfer files between two mac computers. The network is wireless-N and both computers have wireless-N modules in them. The problem is that when I transfer files between them, via file sharing (afp) the network speed caps at 2 megabytes/sec. Just downloading files from the internet I can get faster speeds, so this isn't a constriction of my wifi bandwidth, it appears to be a constriction of the protocol being used. My wifi-n is set to 130mbits, so I should see real world transfer speeds around 12-16 megabytes/sec I did this command on both computers sudo sysctl -w net.inet.tcp.delayed_ack=0 which is supposed to lower tcp overhead, but this did not affect it. How can I get the speed I am expecting?

  • Microsoft Wireless Keyboard 3000 v2.0 not working, but paired Wireless Mouse 5000 on same receiver does?

    - by John Straka
    I have a Microsoft Wireless Keyboard 3000 v2.0 that was bought paired with a Microsoft Wireless Mouse 5000. They're both Bluetooth and use the same receiver. The keyboard no longer works. The receiver is fine, as the mouse still works. The keyboard is still detected by Windows when the receiver is plugged in. The batteries have been replaced. There are no on/off switches on the keyboard or mouse, and no re-sync button on them or the receiver. Results are the same when using the receiver in a different USB port, or on a different machine. Anything else I might try to fix this, or should I hold a funeral for the keyboard?

  • Best use of new express card on Windows

    - by jckdnk111
    I just bought a 48GB SSD express card for my laptop and I am trying to decide how best to use it. I will be running some sort of virtualization (prob VirtualBox) to test / learn Windows Server administration. I am running Windows 7 Ultimate 64 bit. I have 4GB of RAM and a 7200 RPM SATA hard disk. The express card will read at 115MB/s and write at 65MB/s. So how best to use this new disk? Readyboost, relocate pagefile, store VM disks, mix / match?

  • Share the DVB card on windows 7 [closed]

    - by Bashar Kernel
    I have 2 computers connected to a router and I have a DVB card in one of them. I want to use the one DVB card to feed both of them. I read about it and I know that I want to share the DVB adapter with the Internet Connection Sharing on the LAN network. But when I use the connection sharing, I lose my internet access I tried to use "Bridge Connection", but then I also lost my internet access too. Can any one tell me how to fix this problem? And how to view the channels (for example how to use the VLC)?

  • Issues with new graphics card and drivers

    - by Ortund
    With my onboard graphics card (Intel HD 4000) I was able to use 1680x1050 screen resolution. Using the same screen and an Asus ENGTS250 graphics card with 296.10 drivers installed, I'm not able to use that resolution anymore. Also, I've been having other trouble with driver installations. Using 340.52 or 337.88, I can't boot into Windows 7. I see the Windows Welcome screen and then the screen goes black, loses signal and the computer locks up. I think the drivers issues and the resolution problems go hand-in-hand. I have a feeling I could use a newer driver than 296.10 which would give me access to use the 1680x1050 resolution I want to use, but I'm terrified that if I update or install another driver, that the computer will lock up again. Can anyone recommend a [better] driver for me to use?

  • Is Ubuntu recognizing and/or using my NVIDIA graphics card?

    - by user212860
    This is my first post here, and I'm pretty new to Ubuntu/Linux. I currently have no other OS except for Ubuntu 13.10. (I used to have Win7 until i got a new terabyte hard drive). My current PC build, if any of this helps: CPU: Intel i5 quad-core Graphics: NVIDIA GeForce GTX 650 RAM: 8 GB HDD: 1 TB SATA 3 Motherboard: MSi Z77 A-G41 OS Ubuntu 13.10 So I recently installed Ubuntu 13.10 and put Steam on it, and I'm seeing that my games run a lot slower than they did when I had Win7. I figured it was a graphics problem, so I checked System Settings Details Overview. It says in "Graphics" that I have "Gallium 0.4 on NVE7" (don't really know what that is). Does this mean that Ubuntu is not using my graphics card? In System Settings Software & Updates Additional Drivers, it clearly shows like this: NVIDIA Corporation: GK107 [GeForce GTX 650] -This device is using an alternative driver (And then it shows a list of drivers that I can switch back and forth to) So this is a bit confusing. In Software and Updates, it clearly shows that I have my NVIDIA card installed, and that I have a driver selected for it. But in System Settings, it shows I have some Gallium 0.4 thing. I had done a bit of research, and ended up typing command: "lspci|grep VGA" in the Terminal. It showed this in response: VGA compatible controller: NVIDIA Corporation GK107 [GeForce GTX 650] (rev a1) The Terminal seems to recognize my graphics card. What it looks like to me, is that I don't have the proper driver, and I might be using my CPU's integrated graphics. When I switch around which driver I am using in that list, it still does not see my card in System Settings. Some of the drivers in the list give me some sort of OpenGL error when I try to run a game. It might just be that my games are running slow because the game developers have not optimized it for Ubuntu that well. However, that still doesn't take away from the fact that System Settings is not showing my NVIDIA card. TL;DR Version: How do I know if my video card is being recognized/used? If my video card is not being used, what is the best way fix that? Please make your answers easy to understand. I do not mind wordy responses, as long as I can follow what you're saying. Any help would be greatly appreciated! Thanks, Jabber5

  • No HDMI Audio with GeForce 9600GT and nForce board

    - by Bobby
    I've been trying to get HDMI with sound working for the last few days, and I'm a little bit out of ideas. (I've verified that the hardware/Setup works via Windows.) aplay does not list my HDMI device: $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: NVidia [HDA NVidia], device 0: ALC662 rev1 Analog [ALC662 rev1 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: NVidia [HDA NVidia], device 1: ALC662 rev1 Digital [ALC662 rev1 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 I've already compiled the alsa drivers (1.0.24) from a snapshot (with --with-oss=no) and added the line options snd-hda-intel model=auto # Tried 3stack-dig and 6stack-dig too to /etc/modprobe.d/alsa-base.conf. Still, the device does not show up. If it is important, the HDMI TV is at the moment not configured to be part of the X session (I've tried that to, at least with X restart, and it didn't change anything).

    Is it possible to to connect to multiple networks at the same time using the AirPort wireless card on my iMac 21.5"? Can I connect to an ethernet-based network at the same time as I'm connected to one (or more) wireless networks? Can I share files directly between a PC and Mac via ethernet? How so? Thanks.

  • Windows XP ad-hoc networking

    - by Abhinav
    I have been using a Windows XP ad-hoc wireless network to connect my Macbook to the internet. Everything was working fine until after a restart of the XP machine, the network stopped appearing in the "Choose a wireless network" screen. It does not show up as an available network on the Macbook as well. But when I try to create a new network it shows me the network name. Creating a new network does not work either.

  • CSMA/CD and CSMA/CA

    - by Zia ur Rahman
    CSMA/CD is used in wired LANs, CSMA means that the computers on the network sense the medium if the medium is idle, the computer transmits otherwise it defers sending.CD refers to collision detection. I don’t want to write about CD because its not related to my Question. Now in case of wireless LANs we use CSMA/CA , here CSMA refers to carrier sensing , the Question is how carrier sensing is done in case of wireless LANs? the collision avoidance is done by sending the control message to the intended receipient.

    - by Fellknight
    I recently bought a Toshiba X500 laptop with decent speakers & sound card in it. I want to use headphones but im unsure if they also need to have the same audio channels as the sound card (5.1 in this case). Also The laptop itself only has the two standard sound ports - headphones and microphone, does 5.1 headphones require a special kind of connection?.

    I'm interested in hooking up three things to a wireless router: speakers, a printer, and a hard disk. At first the obvious solution was Airport Express, but then I found out that Airport Express does not support hard disks. Any ideas as to other wireless routers that would have the requisite feature set?

    When I run wireshark on a wired network it works fine and reports all of the packets. When I run it on a wireless network though I only see my own traffic. The wireless card I have is supposed to support packet capture and go into premiscous mode, but I don't see any other system traffic. What is wrong?

    My in-laws are having trouble with signing into their Verizon Webmail account at webmail.verizon.net, only when they are on their wireless network. When they try to log in from wireless they get "Error 324" in the browser, in both Google Chrome AND IE8. But they can access any other site, and they can get on their Verizon email when they plug in directly to the browser. Does anyone know why this is?
