• WLAN LED randomly blinking when there is no traffic

  - by mrc

  Hi, I've got a Linksys WUSB54GC WLAN USB interface (Ralink chipset) and I'm running Debian GNU/Linux 6.0. The LED very often randomly blinks although there is no traffic in the network. I checked this with Wireshark. Sometimes, but rarely, the LED stops blinking. The issue is present in Ubuntu and Fedora too. It was not present in Debian Lenny with Linux 2.6.28. I checked an old live cd with ubuntu 8.10 with kernel 2.6.27 and it was also OK. So I guess that's an issue with Linux kernel and its wireless driver or firmware. Has anybody observed a similar thing? Does anybody know how to help this annoying blinking? Thanks.

• WiFi: Connect to a network with hidden SSID in Windows 7

  - by Dor

  I have Windows 7 with the following station: D-Link DWA-160 Xtreme N Dual Band USB Adapter(rev.A2) (driver version 3.5.0.21). I'm trying to connect to a wireless network that has an hidden SSID with the command: Netsh wlan connect name="myNetworkProfile" The profile is configured to connect even if the network is not broadcasting its name (SSID). Despite that, the command fails promptly every time with the message: The network specified by profile "myNetworkProfile" is not available to connect. Nonetheless, when trying to connect manually using the dialog box (see image below), it successfully connects to the network after about 10 or 15 seconds. Also, Please - no need to elaborate about how useless the hidden SSID feature is.

• 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????

• D-Link DWA-125 constantly disconnecting in winXP, but works fine on ubuntu..

  - by sil3nt

  Hey there, I'm dual booting winXp and ubuntu 10.10. I'm using a DWA-125 usb adapter to connect to my home wifi connection and I'm having this odd issue. First off, in ubuntu the adapter works fine and I have no trouble at all, but when I boot back in XP I get a dlink connetion wizard and the connection times out after every 2 minutes. It's odd because I can actually load up web pages and use the internet for 2 minutes, and then it would disconnect and the whole thing would repeat. I did a system restore on xp and this stopped the whole connect-disconnect thing but once I booted into ubuntu and came back to xp it started all over again!(?). Any ideas as to how I would go about fixing this?

• Backup and restore.

  - by Xavierjazz

  I have a Thinkpad T60 with a 150GIg internal hard drive. XP Pro SP3. I also have a similar hard drive that used to be in another laptop connected via USB. It contains only data. I have cleared out a lot of duplicate files and now would like to back both up. I have Retrospect and a brand new 1Tbyte drive for this purpose. Can I back up the whole computer (both drives) but, in case only one fails, can I just restore that drive or do I have to restore both drives at the same time? I don't understand how partitions work so might I be able to partition the 1T drive and restore each smaller drive independently? Thanks.

• Full Backup & Restore for Windows Vista

  - by Thomas Matthews

  I'm looking for a freeware or low cost application that will backup everything, including registry on Windows Vista Home Premium and to restore from a CDROM disk. The destination is an external hard drive on USB 2.0. Searching on SuperUser and Stack Overflow show articles, but don't mention full backup of the registry and complete restore using CDROM. I would also like to have compressed output and incremental backups. One article mentions CloneZilla, but their web page says that the incremental feature is not supported. I am using Windows Vista Home Premium, Service Pack 1. I need to backup 200 GB onto a 230 GB drive and would like to have multiple backups (thus the need for compression). Other requirements: Single file restore Quality is more important than performance. Application must run on Windows Vista. Extra: Run as daemon or background task on 4 user system. Thanks

• UPS for hard drive protection

  - by dimi

  I am in a place where electricity is not ideal (old house, no ground), sometimes it occasionally shuts down and supposedly there are some spikes. I consider using UPS with the goal to increase safety of my personal data. My first priority is the health of my internal and external USB hard drives which can be damaged due to possible power instability. I do not care that much about possible losses of not-saved work, instead I just want to let my system have a minimum time to turn off without any risk of physical damaging my hard drives. Would a cheap offline UPS suit my neads? Or do i need a better one with automatic voltage regulator (AVR)? How critical is AVR for the hard drives? The external ones require their own power supplies and will be plugged directly into UPS.

• Dell 620 display is too bright to use

  - by keith

  I have a Dell D620 with a display problem. In windows 7 the display seems to be too bright, the text is broken up, the only way to see the mouse is at a very oblique angle. Changing the brightness with fn and brightness control has little/no effect. When I put it in high contrast mode I can see all the colors, but any windows pictures etc are still useless. I cannot get it to connect to an external monitor via VGA port or via a USB-VGA connector.

• Printer Problems: Snow Leopard with Epson CX 4200 - worked and then didn't?

  - by user33521

  We got a new laptop in the office with Snow Leopard. We installed the new driver for the Epson CX 4200 printer we have and it seemed to be working okay. However, after an Apple update, the printer stopped working. A few days later we saw an update for the Epson driver and so we downloaded and installed that. However, the printer still isn't working. We plugged and unplugged the printer power cable and usb cable, and also tried replacing the ink (because the colour ink light was blinking)...however the printer still isn't working?

• Dual External Monitors Through Docking Station on ASUS G73JW-XT1

  - by user60695

  I am getting an ASUS G73JW-XT1; and I would like to set it up so that I can plug it into a docking station at my desk, and use 2 external monitors (not the laptop display and an additional monitor). The computer supports a DVI and HDMI output, but I cannot find any docking stations that will support two external displays, as well as audio ports and USB ports for other peripherals. Does anybody know of a specific docking station that will do this, or another workaround without having to plug in several things to my laptop every time I bring it to my desk?

• Netgear WNR1000 WiFi speed

  - by Kamil Klimek

  I have Netgear WNR1000 150N, Macbook Pro 13" with Broadcom BCM43xx 1.0, Network connection 60mbps When I connect through the cable I easily get around 60mbps. When I go through the WiFi it's capable to get only 32mbps at tops. Any ideas why is that? Is that my router limitation or maybe my WiFi card? If it is routers fault what router would you suggest. Best router would be with usb port for external hard drive. Forgot to add screenshot with connection details: Szybkosc transmisji == Transmission speed

• Linux says a kernel module has an unknown symbol, but another loaded module provides it.

  - by raldi

  I'm trying to install a driver for a USB DAQ box, which annoyingly, I have to compile myself. I believe I've succeeded -- I have two .ko files: -rw-r--r-- 1 root root 45271 2010-03-18 21:24 advdrv_core.ko -rw-r--r-- 1 root root 24312 2010-03-18 21:24 usb4761.ko I was able to run insmod on the first without incident, but when I try on the second, I get a flood of messages: kernel: [686782.106547] usb4761: no symbol version for adv_process_info_check_event kernel: [686782.106555] usb4761: Unknown symbol adv_process_info_check_event kernel: [686782.106691] usb4761: no symbol version for advdrv_unregister_driver kernel: [686782.106695] usb4761: Unknown symbol advdrv_unregister_driver However, advdrv_core.ko provides these symbols.

• How to install Windows7 on Hitachi HTS545050a7e380 harddrive?

  - by wurlog

  I have a Samsung NP530U3B with a Hitachi HTS545050a7e380 Harddrive. In the Bios it shows as one drive Hitachi hts545050a7e380 When I try to install Windows 7 it show 2 drives in the setup Drive 0 with 15 GB Drive 1 with 460 GB Guess it is a hybrid of SSD and normal harddrive, right? I tried to install it on the second drive, but after restarting it goes back into the beginning of the Windows 7 installation. The installation routine automatically activated a 100 MB partition on Drive 0. I guess for the bootmanager. Second try: Installation on the 15GB drive. The same. After reboot it wants to install win7 all over again. If I remove the USB Stick I get the message "Missing operation system" Any ideas?

• Suggestions for a SOHO/Home Asterisk system

  - by James

  I would like to buy a small embedded system that runs Linux and Asterisk. I would like two FXS ports ( to plug analogue phones into ) and one FXO port ( to plug in to my real line to allow access to the POTS ). I would like it to have a USB port to hold storage for voicemail. I really want it for home use so I would like it to be under £150 ( say $250 ), given that you can buy ADSL routers for around this much can any of them be made to run Linux and Asterisk? I don't want a PC as the power usage would be too high. I am looking for something like this ASDL router but open and able to run Asterisk or another open PBX. At worst I would like a box which had one FXO and two FXS and just made them completely available over IP to a full Asterisk system on a low power Atom system.

• increase performance of virtual machines on the 27" imac

  - by evan

  I'm using a 27" iMac (i7, 8GB RAM) at work and normally run two or three virtual machines at the same time, which hurts the performance of each virtual machine. I've learned on these forums the best way to increase virtual machine performance (aside from RAM) is to have them running on a separate hard drive from the one the OS is on. Of course with the iMac you can only have one hard drive and not even an SAS or solid state drive (well you could probably take it apart and put one in yourself but I wouldn't be permitted to do that). That being said, do you think it would help to run one or more virtual machines from a firewire external drive (or a usb 2.0)? Thanks for your input!

• Why does the EFI shell not detect my Windows DVD?

  - by Oliver Salzburg

  I'm currently looking into (U)EFI for the first time and am already really confused. I insert the Windows Server 2008 R2 Enterprise disc into the DVD-ROM and boot into the EFI shell. The shell will automatically list all detected devices, which are: blk0 :CDRom - Alias (null) Acpi(PNP0A03,0)/Pci(1F|2)/Ata(Primary,Master)/CDROM(Entry0) blk1 :BlockDevice - Alias (null) Acpi(PNP0A03,0)/Pci(1F|2)/Ata(Primary,Master) To my understanding, it should have already detected the filesystem on blk0 and should have mounted it as fs0. Why is that not happening? If I insert a USB drive, it gets mounted just fine. The board is an Intel S5520HC in case that makes a difference.

• Exchange enrypted messages with a single recipient [portable]

  - by Andy

  I need to exchange encrypted messages with another party. These would be in the form of email like communication (not instant chat). The solution needs to be portable (USB stick). I've tried "Portable Thunderbird/Enigmail/Gnupg/Hotmail account" but it's just impossible to setup portable, countless meaningless error messages. Anyway, I would prefer something more straightforward. Notes: We won't know each others IP addresses. Our computers will often be switched off. Encryption would ideally be using a common password. Is there a solution to this?

• Can't connect Alienware M11x wireless to internet thru families router

  - by Jim Kron

  Morning All, Have an Alienware M11x loaded with Win 7 Premium with the Dell half card wifi. Also have a Netgear and Belkin USB external adapters (b/g and N to include dual radios. No joy either. Families Internet is served thru Charter and they use a Motorola Router. No matter if we reset the router, I cannot connect to the Net but can talk to the router. BTW... my brother only uses WEP as a number of connected items are old and my folks are not in a high threat area for attacks. Frustrated, as I know what I'm doing but this really has me stumped. Any thoughts? Much appreciated, Jim

• Can't run Ubuntu from disc

  - by alex

  When I place the boot CD in my CD drive and boot from it, I get the Ubuntu menu. I have these options Try Ubuntu without any change to your computer Install Ubuntu Check disc for defects Test memory Boot from first hard disk I can use the cursor keys to select them, and I can push F1 for help etc. However, I can not select an option. I've highlighted the first and tried enter, space bar etc. I do have a KVM, so I plugged in a 2nd USB keyboard and tried it but no go either. I can push escape and then got to the prompt. Am I doing something wrong?

• Format External HD on Airport Extreme Base Station?

  - by David.Chu.ca

  I just got an Airport Extreme Base Station. I am planning to use this one replace my current Linksys router. This works fine. My another purpose of getting this device is to use its USB port to connect to several external HDs as my backup Time Machine. I can see one 500GB HD through Airport Base Station. However, I cannot format it by using Disk Utility. What I did is to connect the HD to my iMac directly first and then clean and format the disk by Disk Utility application. Then I move the HD to the Airport Base Station. After that I can designate the HD as my Time Machine destination. Is there any way to format the HD connected to Airport Base Station? Any issues to use an external HD through Airport Base Station for Time Machine backups?

• Properly configuring Linux keyboard on my laptop

  - by antoniocs

  Hey! I have a ps/2 keyboard connected to an Acer Aspire 1694 WLMI via a ps/2 to usb converter. The laptop is running Ubuntu 9.04. The keyboard is a HP model number: SK-250C. I have configured in the 'Keyboard Preferences' the layout to HP SK-250x Multimedia Keyboard. The big problem is when I press certain keys (like for example the arrow keys) I get the 'Save Screenshot' dialog. This is really getting annoying, sometimes I am tying to write an address in browser and just want to go back a few letters and can't. There are other keys that trigger the dialog also (windows key, insert key, home key, page up and page down key, delete key, end key) All works fine If I use the laptop keyboard, but I really want to use the HP keyboard. EDIT: I was testing this and it seems that if I have the 'Num Lock' key turned off the keys work properly. Strange but true!!

• Can make the proxy settings invisible when I share my internet connection via wifi?

  - by Neil

  This is probably a long shot... I have an HTC Desire and frustratingly found out after I got it that it doesn't support network proxy settings. We have a wireless network at my office that uses a proxy. My desktop at work runs ubuntu. I was wondering if the following set up would work: Plug a USB Wireless adapter into the desktop that has a working internet connection using the proxy. Setup the wireless adapter as an ad-hoc network Share the internet connection over the ad-hoc network. Make it so that the use of the proxy is invisible to users of the shared network connection. Connect the Android phone to the ad-hoc wireless network and utilise the internet connection. My question is this: Is this possible or should I give up now and not even try? I think I can handle steps 1, 2, 3 and 5. I just have no idea if step 4 even makes sense, let alone is possible. Thanks

• Easy way to restrict permissions in an elementary school computer lab?

  - by Andrew

  I'm putting together an elementary school computer lab. I have nine winxp pro machines that are not networked and do not have internet access (no money to do either). I've created separate student and admin accounts, and have the students set as limited users. However, I'm interested in further restricting their permissions. I want to make it such that they cannot: -delete any files, even just from their own profile -rename any files -move around the icons on the desktop -change any display settings -access a usb device without a password (they bring in their own from home which are chock-full of viruses) Oh, one last thing, they still have to be able to save word documents. Is this even possible? I can download software, but, like I said: no internet, no server.

• Darik's Boot And Nuke - ERROR /dev/sda

  - by user1403844

  I'm trying to wipe the drive of an old company computer with DBAN so I can install Redhat Enterprise and learn Linux (it's a Dell Inspiron 1210, if that matters). I burnt DBAN to a CD and boot from that CD (running on an external USB CD drive). Whenever I try to run the utility--whether it's Autonuke, or any of manual wiping methods-- it spits on the errors: ERROR /dev/sdb ERROR /dev/sda From what I've read on some other forums, there are some issues with other drives or removable media interfering however I've disabled all other drives in bios, leaving just CD/DVD and the Hard Disk but still no luck. Any advice on how I can reconcile these errors and wipe the disk?
