  • HP Pavilion DV6 doesn't recognize wireless networks

    - by Mike N.
    Okay so about a few weeks after I got my laptop the wifi would connect and disconnect, off and on. And every time I troubleshoot it, a message comes up saying there's a network cable not properly plugged in or broken... It's been doing this for about a year and I usually just tap the bottom of the laptop or something and the wifi connects again but now it refuses to turn back on, how do I fix this?

  • Using a Blackberry Bold as an IP Modem on Windows 7

    - by Lawrence
    I recently installed Windows 7 and now cannot use my Blackberry Bold as a modem (via a USB cable): When I query the modem it is successful. I have added the correct "at" commands. When I try connect it says "connecting modems" but then it times out with the following error: Error 638: The remote server is not responding in a timely fashion. I also have the latest desktop manager software installed.

  • Is minimum latency fixed by the speed of light?

    - by JavaRocky
    Suppose i had a fiber optic link from one side of the planet to the other side of the planet. Is it safe to say, that with current technology, the latency of communication can never be reduced? Understand that a fiber optic cable is not a perfect medium thus data only travels close to the speed of light. Also lets consider that i will not be drilling a hole thru the center of the earth and it is just running along the ocean.

  • Why is SMB from a Windows 7 64-bit to OS X Server so slow when using DNS vs IP?

    - by chuboy
    When I connect my 64-bit Windows 7 to a OS X server using \servername, my transfer rates are around 400KB/s. However, when I do the same thing using \192.168.0.10 (which is the IP of the server), transfer rates jump to 30MB/s. All of this happens via a gigabit ethernet cable with my wireless disabled I heard Samba itself "doesn't use DNS", but if that's the case, how am I able to connect to the server in the first place?

  • Creating an ad-hoc wireles network on a router

    - by bo7ons
    My router is a Wag200g with openwag firmware. My laptop is connected to the university's internet through an ethernet cable and i have to set the browser proxy settings to connect. I want to create an ad-hoc network with a router so that i can let my laptop do the proxy routing/forwarding itself and that my android phone can connect to it and use my university's proxy (I've tried setting the proxy on my phone but it wont work).. Or am i approaching this the wrong way?

  • Get 5.1 surround sound from computer through a VCR config?

    - by Wedding Nails
    I'm posting to see if my idea of this setup is right and can be done. I currently have the following "equipment": a JVC VCR -quite old-, which has built in surround sound (aka it has several speaker outputs, which I believe is 5.1 and are connected to several speakers that are in every corner of the room), a computer with SPDIF optical output and a new flat screen TV (with built in HDMI). I want the computer to take advantage of the VCR's surround system (all the speakers in the room) in order to play mainly music and video always with all the speakers (5.1) and with the maximum sound quality. Currently, the computer plays sound only through the front speaker (I connect one output to the on board pc audio input) and the quality is really bad. As a side note, the computer video runs with S-video (old school), and the picture quality as you would imagine, is really bad with the new big LCD screen. My main goals are: to upgrade the picture with a new video card which would support HDMI (my tv has HDMI). to buy a SPDIF optical cable, connect one end to the VCR SPDIF input and the other end to the PC output This is theoretically what I've researched so far, and I came out with several questions: in this case, with the SPDIF cable connected, and all the configurations done in windows allowing the 5.1, will I get every content I play "converted" or played through all of my speakers? (I read this forum post). I already know that in order for this setup to play from all the speakers, the content/audio source has to be 5.1. but my question is, if there is a way to play from all of the speakers no matter what type of content I'm playing (that's why I said conversion there) I already know that HDMI cables carry digital sound. Is there a way I can only use said HDMI cord to the tv, and get sound through the VCR? (I'm not too sure about this, I would have to disable the TVs speakers and use the VCR surround as default, but I have no clue wether this can be done or not). Update: The ultimate question is, do I really have to rely on "sound virtualization" technology to get sound from all the speakers, no matter what content I play? (do I require a newer sound card, like a creative soundblaster with said technology?) Thanks!

  • applescript: establish PPPoE connection

    - by user26700
    how would an Applescript look like that connects to a specific PPPoE configuration? i want to trigger this via Launchbar. (or a more fancy script which checks if the current chosen network location is the right one and if an ethernet cable is plugged in, then connect to the PPPoE service automatically. i'd be completely satisfied with the simpler version though)

  • Burnt SATA Drive

    - by luvieere
    By stupid curiosity, I've connected the FDD power cable to the jumper pins of a SATA drive, and powered on the system. The SATA drive's controller burned out. What now? Can it be replaced, and still be able to read the disc?

  • Remote Router Access For Linksys WRT54GL

    - by Tim
    Hi, I just set up a wireless network at home using a Linksys WRT54GL. All was fine except that I can still access 192.168.1.1, the configuration setup page of the router, within the local wireless after I disabled "Remote Management". I think if remote access is indeed disabled, one can access my router setup page only by using a cable connecting from his computer to the router. Is this true or am I wrong? Thanks and regards!

  • Can I prevent tv-out from disconnecting when monitor sleeps?

    - by Damon
    I have my TV connected to my computer (windows 7) through an HDMI cable that also carries the sound. I like to put on music on my TV, but the problem is when my monitor goes to sleep back in my office, it switches off the hdmi connection completely and the audio goes back to my PC. I would like a way to stop this from happening without turning off sleep mode entirely. I have an ATi Radeon 5700

  • Flickering issue in external monitor when used with Acer Aspire One D260 netbook (Intel GMA 3150)

    - by seyenne
    I recently purchased a Acer netbook, Aspire One D260. It runs flawlessly. Yesterday I bought a Samsung 23" TFT with a native resolution of 1920x1080. According to the information found in the internet and my local computer dealer, the Intel chipset can handle the native resolution of the monitor. However, this is only partly the case. I use the VGA cable to connect, the monitor instantly switches to the native resolution and now the problem: Occasionally, especially the first 2 hours after booting up, I have a flickering all over the screen, sometimes the entire screen is shaking and spinning around like crazy. I figured out that lowering the resolution avoids the flicker but this helps only for some time. I can rule out that it's the monitor's problem since I found no issues with another notebook. Right now, I have no problems with the netbook, for about 30 minutes I didn't experience any issues... But I don't know for how long, it occurs without warning :-) I'm worried that if I would bring the netbook back to the dealer and explain my problem, after testing it on an external screen in the local shop, everything works just fine... And I won't get helped with the problem because I can't prove it. (I'm currently in Thailand and over here, customer service is nothing like back home in Germany) What can I do? Is this a driver related issue? (I installed the latest GPU driver) Is it because of the VGA cable? (But why does it work sometimes without any problems and with no issues on the other notebook) I monitored the GPU/CPU temperature, nothing changes really over time.. Can it simply be a faulty GPU and is a replacement justifiable? I'm really stressed now because for the time I'm writing, the flickering didn't occur... but for sure, soon or later it will happen again.. I forgot to mention, the problem also happens if the netbook runs on battery, unplugged. So the only hardware that is plugged is the TFT screen. ...........and here it comes again, flickering has just begun. NEED HELP! Thank you all for reading through this and giving any suggestions if possible. Cheers

  • Idiots Guide to Setting Up Myth TV?

    - by Jared
    I want to build a MythTV back end. I don't want to compile things if I can help it, and I'd like to know what hardware will work with the cable system in the US. Are there any guides to building a MythTV box? I've found several but they all appear to be three or so years out of date and I have no clue how Linux hardware support has changed since then.

  • Connecting to internet via phone on Linux

    - by Bart van Heukelom
    I have a Sony Ericsson C702 phone with a flat fee internet subscription (GPRS/UMTS). I'd like to connect my Linux (Kubuntu 9.04) laptop to internet via this phone, using bluetooth (I also have a cable connection but that's propietary, doubt it'll work). How can I do this, preferably via GUI / NetworkManager / the BT applet that comes with KDE? In Windows I use SE's PC suite software which works great, but is not available for Linux.

  • TCP/IP & throughput between FreeNAS (BSD) server & other LAN machines

    - by Tim Dickerson
    I have got a question for someone that knows BSD a bit better than me that are in regards to my LAN setup at home/work here outside Chicago. I can't seem to fully optimize my network's (LAN) thoughput via my FreeNAS (BSD based) file server. It runs with the latest FreeBSD release which is modified to support several protocols for file transfers and more. Every machine that is behind my Smoothwall (Linux based) router is on the usual 192.168.0.x subnet and for most part works just fine. Behind the Smoothwall box, all machines are connected to a GB HP unmanaged switch. I host a large WISP here and have an OC-3 connection here at home/work and have no issues with downloading/uploading from/to the 'net'. My problem is with throughput. When I try and transfer large files...really any for that matter..between any of the machines to/and from the FreeNAS server via FTP, the max throughput I can achieve say between a Win 7 or a Linux box is ~65Mbit/sec. All machines are running Intel Pro 1000 GB NIC's and all cable is CAT6. Each is set to 'auto negotiation' and each shows 1500 MTU Full Duplex @1GB so I know the hardware is okay. I have not adjusted the MTU on any machine as I understand it to be pointless unless certain configurations are used (I assume I am not one of those). My settings for the FreeNAS machine are the following: # FreeNAS /etc/sysctl.conf - pertinent settings shown kern.ipc.maxsockbuf=262144 kern.ipc.nmbclusters=32768 kern.ipc.somaxconn=8192 kern.maxfiles=65536 kern.maxfilesperproc=32768 net.inet.tcp.delayed_ack=0 net.inet.tcp.inflight.enable=0 net.inet.tcp.path_mtu_discovery=0 net.inet.tcp.recvbuf_auto=1 net.inet.tcp.recvbuf_inc=524288 net.inet.tcp.recvbuf_max=16777216 net.inet.tcp.recvspace=65536 net.inet.tcp.rfc1323=1 net.inet.tcp.sendbuf_inc=16384 net.inet.tcp.sendbuf_max=16777216 net.inet.tcp.sendspace=65536 net.inet.udp.recvspace=65536 net.local.stream.recvspace=65536 net.local.stream.sendspace=65536 net.inet.tcp.hostcache.expire=1 From what I can tell, that looks to be a somewhat optimized profile for a typical BSD machine acting as a server for a LAN. I might be wrong and just wanted to find out from someone that knows BSD better than I do if indeed that is ok or if something is out of tune or what. Are there other ways I would find better for P2P file transfers? I honestly do not know what I SHOULD be looking for with respect to throughput between the NAS box and another client when xferring files via FTP, but I am told that what I get on average (40-70MB/sec) is too low for what it could be. I have thought about adding another NIC in the FreeNAS box as well as the Win7 machine and use a X-over cable via a static route, but wanted to check with someone first to see if that might be worth it or not. I don't know if doing that would bypass the HP GB switch and allow for a machine to machine xfer anyways. The FTP client I use is: Filezilla and have tried both active and passive modes with no real gain over each other. The NAS box runs ProFTPD.

  • Why is Wifi data transfer is slow?

    - by Ali Azam Rana
    I have a wifi router which was attached with my modem, and the pc was connected to the wifi router through an ethernet cable. Yesterday I moved my modem and router to another room and connected my PC with wifi through an external wifi usb dongle (tp-link tl-w722n). I noticed that the file transfer speed from my cell to PC via wifi is greatly affected. I am not clear why is this happening because although PC is now connected through wifi but the dongle supports more than 54Mbps which is still enough.

  • Ethernet run tests green but won't connect

    - by Simon Gillbee
    I have a single ethernet run at home that I just added. I have a cable tester that tests for pin/pair crossover or miswired pins. The entire line tests green (all 4 LEDs light up green on the tester) but I can't get any PC to connect through the link. No link light on the ethernet connection. Any simple tests/fixes, or do I rip out the wall sockets and do it again?

  • Fiber optic internet, final connection to lan

    - by RayQuang
    Hi, We have fiber optic internet coming to our office soon, and i would like to know if it would be worth installing fiber NIC's in our servers and machines instead of using cat6 gigabit. Here is the layout: (fiber) cable from distribution point in basement - fiber optic modem - Network gateway (debian lenny) - network computers and servers I was wondering if it would be worth installing a fiber connection from the modem to the gateway and the network clients. Will the costs be worth it in terms of speed, latency and stability? Thanks, RayQuang
