  • Broadcom 4313 Signal strength very low on an HP Pavilion dv4

    - by thegreyspot
    I have a HP pavilion dv4 4141US laptop running fresh ubuntu 11.10. This laptop has a broadcom 4313gn chipset for the network card. The network card is using the brcmsmac driver. Which, I heard else where on askUbuntu that its the best driver to be using for this card. I can connect to my network, however I have extremely low network signal. Right now I am right in front of the router, and I only get 72%. If i go to the room directly behind the router's wall, i get no signal, where as with windows 7 I get a nice 70% percent. UPDATE: I use WEP at home and an open wireless connection at work. Both have same result. Both are completely different routers. Also you G What can i do?

  • How do I get my RTL8192ce based wireless device working properly?

    - by JonnyTruelove
    I am using the rtl8192cu chipset (on a Belkin wireless USB adapter N300) combined with 64 bit architecture and the 3.8 kernel. Some of you may know that this doesn't work. I tried this fix - RTL8188CU USB Network Adaptor on ubuntu 13.04 and now my internet is super slow. I am totally new to Ubuntu and I am concerned I do not have the right driver. The "stock" driver was the RTL8192cu, but it didn't connect 99% of the time and if it did the upload speed was higher than the download. Right now I am connecting through my laptop with a crossover cable, so my internet connection is just fine in my apartment. Relevant output from lsusb is here: Bus 002 Device 002: ID 050d:2103 Belkin Components F7D2102 802.11n N300 Micro Wireless Adapter v3000 [Realtek RTL8192CU] (bonus question: is that [050d:2103] the actual physical address straight from the hardware? Or does it change when I put different drivers on it? I am concerned I do not have the right driver)

  • dig @server doesn't work

    - by JustTrying
    I have Ubuntu 12.04 with BIND9, working just as a caching server (forwarding to 8.8.8.8). When I use, for example, dig +norecurse @l.root-servers.net www.uniroma1.it, I obtain the following output ; << DiG 9.8.1-P1 << +norecurse @l.root-servers.net www.uniroma1.it ; (1 server found) ;; global options: +cmd ;; connection timed out; no servers could be reached Using Wireshark I discovered that the outgoing queries are correct, but there aren't any incoming answers. Why? P.S. Using simply dig www.uniroma1.it I obtain the correct answers.

  • Simpler Times

    - by Simon Moon
    Does anyone else out there long for the simpler days where you needed to move a jumper in the jumper block to set your modem card to use IRQ7 so it would not conflict with the interrupts used by other boards in your PC and your modem card came with a 78 page manual telling you everything you would need to know to write your own driver for the board including a full schematic along with the board layout showing every chip, capacitor, and resistor?  Ahhhhh, the simplicity!I am wrestling with UserPnp issues for a USB software licensing dongle that is needed by some third party software in one of our production applications. Of course, every machine in production is virtual, so it could be anything in the chain of the software application library to the device driver running on the VM to the configuration of the simulated USB port to the implementation of the USB connection and transport in the virtual host to the physical electrical connections in the USB port on the hypervisor.If only there were the virtual analog to a set of needle-nose pliers to move a virtual jumper.Come to think of it, I always used to drop those damn things such that they would land in an irretrievable position under the motherboard anyway.

  • brother MFC-J435W wireless scanning issue

    - by ogreen32
    Thanks for taking the time to read this. I have a brother MFC-J435W and I was able to get the printer set up for wireless printing, but it is not allowing me to scan wirelessly. It gives me the message to "check connection". I'll tell you what I've done so far and maybe someone can help me out. I've installed the scanner driver and scan tool I installed Xsane (to see if it would allow the scanner to communicate with the computer and that didn't help). I've tried restarting the computer. After those things I am now at a loss as to where to go from here. Any help would be great. Thanks. I've also searched for this question in the Brother FAQ as well as on here and I haven't found an answer. Thanks again.

  • x11 Remote Desktop with Ubuntu 12.04

    - by BSchlinker
    When I was running Debian, I was able to start a remote session over x11 by just typing gnome-session However, with Ubuntu 12.04, this only seems to result in my desktop and background being forwarded over x11 -- the top bar (where the clock is) and dock are both missing. I tried starting all of unity by executing unity, but that just resulted in a segfault. How can I start a Unity 2D session over x11? Edit: I prefer x11 as I need to tunnel the connection over 2 other servers. I would need to do a good amount of port forwarding within SSH to get any other connections back. Of course, if someone has any other suggestions, I'm willing to listen.

  • Install vim offline

    - by rosemary
    I have Ubuntu 12.04.02 desktop in my college Lab of around 15 pcs with no internet connection. I used to install packages : sudo apt-get install vim It was just fine. But, now I want to install vim locally(i.e.,using a pendrive or CD drive). Where and how can I accomplish this,as I am new to it. Through googling, I could get some sites offering packages, but I have merely any idea on how to carry on: https://launchpad.net/ubuntu/precise/+source/vim http://www.ubuntuupdates.org/package/core/precise/main/base/vim http://pkgs.org/ubuntu-12.04/ubuntu-main-i386/vim-gnome_7.3.429-2ubuntu2_i386.deb.html What should I exactly download and where to store it in my ubuntu machine and run commands to properly install vim offline? Any word of advice is appreciated!

  • HTG Explains: Live File System vs. Mastered Disc Formats in Windows

    - by Chris Hoffman
    When burning a CD or DVD with Windows, you’ll be asked whether you want to use a Live File System or a Mastered disc format. Each has its own advantages and disadvantages. Windows 7 refers to this as “Like a USB flash drive” or “With a CD/DVD player.” But how exactly can a non-rewritable disc function like a USB flash drive?

  • Unusable network, packet losses between router and NIC

    - by KáGé
    I have this setup: Gigabyte P35-DS3P motherboard Asus NX1101 PCI network card (the one on the motherboard got fried a few years ago by a power surge) Asus RT-N16 router Windows 7 x64 I think the other specs are irrelevant here, but I'll post them if you say so. Until a week ago everything was fine, but then my network became unusable: websites start loading but timeout before anything would come through (true for the web interface of the router as well), I can't reach the computer from my notebook and Windows' ping utility measures a ~50% packet loss between the computer and the router. Pinging localhost is good. The router works completely fine when wired to my notebook. I also tested different ports on the router, different cables, different router and connecting directly to the modem, but it's still the same. Sometimes it works for a few minutes right after turning on the machine, but then it becomes crap again, but mostly it's useless from the start. I've tried updating the firmware on the router, updating the driver for the network card (after which I started getting BSoDs in every 15 minutes), reinstalling Windows, swapping to Fedora 15 but none of them changed anything. Does this mean that the network card is dying, or could it be something else? If it's the card, what model do you recommend as a replacement? (Could be PCI or PCI-Ex x1) Thanks for your help.

    I can't believe I'm raising this question after years, but after a fresh installation of Ubuntu 12.10, I'm unable to connect Pidgin to Google Talk.

I had used these same settings on 12.04 and it had worked like a charm. Any help will be appreciated.

  • What software is responsible for connecting to the wireless net specified in /etc/network/interfaces?

    - by zuba
    I'm curious what software (package, utility in bin's) handle interface parameters in /etc/network/interfaces and decides to connect to the specified wireless net. I use wifi usb stick dlink DWL-110 attached to wlan0 with ndiswrapper driver. Sometimes wlan0 sees my wifi net - iwlist wlan0 scan shows it, but does not connect to it - iwconfig shows AP Not-Associated, until I replug the stick. Neither reinserting module with ndiswrapper, not ifdown/ifup or restarting networking helps. That is why I need to know what OS entity handles connection/reconnection to wireless net. EDIT: shame on me, I use wireless-tool package with wep encryption

  • PASS Summit '12, Day One

    - by AaronBertrand
    I had an incredibly interesting experience getting to Seattle this week. I flew out of Providence through Philadelphia. Apparently there was some smoke in one of the towers at PHL, so our flight was an hour delayed. I missed my connection by three minutes . I was absolutely amazed that after a one-hour, full ground stop, flights shortly afterward were leaving exactly on time. It was like anti-Aaron magic. I got to the gate and watched my plane back away. My luggage never would have made it but it...(read more)

  • Where is a postgresql 9.1 database stored in ubuntu 12.04?

    I installed and created a Postgresql database on ubuntu. I then created the database using the following command: sudo su postgres createdb mydatabase However, I can't figure out where the database was initialized. I would like to be able to edit the hba.conf file and postgresl.conf files.

  • Ubuntu Freezes w/ Proxy

    - by jrc03c
    Ubuntu 11.04 freezes completely after a little while when using a proxy. It's fine when it's got a direct Internet connection, but it completely grinds to a halt after about 10 or 15 minutes of traffic through a proxy. Any ideas? UPDATE: Here's some more information. I have a second-generation MacBook, which has both OSX 10.6.8 (Snow Leopard) and Ubuntu 11.04 (Natty Narwhal) installed on it. When running through a proxy, Snow Leopard works fine, but Ubuntu freezes frequently. Any suggestions at all? Or, rather, what other kinds of information do you need?

  • CentOS 6.5 new Kernel not active after reboot

    - by Kristofer
    Today I was running some yum updates and wanted to verify that everything went through fine by making sure I had a new kernel. To my surprise I noticed that CentOS was still running 2.6.32-431.5.1.el6.x86_64 even though it looked as though 2.6.32-431.23.3.el6 was installed. Indeed 2.6.32-431.23.3.el6 shows up in /etc/grub.conf but not in the upstart boot options. Any ideas why?

  • Test Doubles : Do they go in "source packages" or "test packages"?

    - by sbrattla
    I've got a couple of data access objects (DefaultPersonServices.class, DefaultAddressServices.class) which is responsible for various CRUD operations in a database. A few different classes use these services, but as the services requires that a connection is established with a database I can't really use them in unit tests as they take too long. Thus, I'd like to create a test doubles for them and simply do FakePersonServices.class and FakeAddressService.class implementations which I can use throughout testing. Now, this is all good (I assume)...but my question relates to where I put the test doubles. Should I keep them along with the default implementations (aka "real" implementations) or should I keep them in a corresponding test package. The default implementations are found in Source Packages : com.company.data.services. Should I keep the test doubles here too, or should the test doubles rather be in Test Packages : com.company.data.services?
