  • Wifi randomly drops on Windows 8 laptop

    - by JosiahS
    First of all, I did a lot of research on this problem, and I wasn't able to come to any helpful conclusion. I've finally decided that I need advice from those who might know where to look. So don't let me down. :P I used to have an older Windows 7 laptop, which worked great for basic office and web browsing. However, I wanted something that would play actual modern games. So I recently bought a Sager NP8235 with the Intel Wireless-AC 7260 wifi card, and installed Windows 8 Pro on it. And ever since, I've been having problems with the wifi. Generally, what happens is if I leave the laptop on but inactive for an extended amount of time (I've estimated it around an hour to two), the wifi will start dropping randomly. If I happened to have a download going at the time, it usually causes the download to fail. Or, if I put the laptop to sleep overnight, the next morning I usually have to restart the computer because the wifi device apparently stops working (it literally won't turn on). Also, and most frustrating, whenever I'm on a video chat (like Skype), after about ten minutes, the connection will start lagging like crazy, until it forces Skype to end the call. After that, I usually have to disable and reenable the wifi to get it working again. I know it isn't our internet, because all the other computers in our house (~8) don't have any issues. Even the old Windows 7 laptop (connected also over wifi) works just fine, scoring the normal ~3Mbps average on speedtest.net (yes, I know our internet is slow, we live out in the country). Additionally, when I connect the Sager directly to the router via ethernet, the internet instantly starts working just great. Like I said, I've done a lot of googling to figure out what's going on, and I haven't been able to find anything that worked for me. Is it Windows 8 conflicting with the Wifi drivers? As of this writing, I have the Intel drivers v16.1.5.2 installed (without the extra Intel software). Or is it our router? It's a TP-Link TL-WR841ND, set to the default settings. The Sager is currently being assigned to a static IP, if that makes any difference. And yet, the old windows 7 laptop has a much more stable connection than the Sager. Anyone have any ideas? At this point, I'd appreciate even knowing what the problem is.

  • Index fragmentation and reorganizing database pages

    - by TiQ
    Say you have a database with heavy index fragmentation. Say this database also has a lot of free space due to frequent deletes in its data file. This free space is not contiguous. If I rebuild all indexes to remove fragmentation and then reorganize the database pages so allocated pages and free pages are contiguous, would this cause further fragmentation in my indexes? I guess the question can be posed as: if it matters, which should I do first, reorganize or rebuild?

  • Exporting members of all DLs in an OU

    - by Bo Shubinsky
    I'm trying to export all the members of all the DLs within an OU (either to a single file that's categorized or individual files). I tried to use: csvde -f "C:\Documents and Settings\root\Desktop\AD Export\DL Export\DL.txt" -r "OU=DLs,OU=Personnel,DC=csi,DC=org" -l "cn,mail" but that only works for individual DLs and there are a lot to input each time. Any help on getting this done in the most efficient pattern would be helpful.

  • Using watch with pipes

    - by Tom
    Hi! I'd like to run this command: watch -n 1 tail -n 200 log/site_dev.log | grep Doctrine But it does not run, because "I think" that the grep tries to run on the watch instead of the tail... Is there a way to do something like watch -n 1 (tail -n 200 log/site_dev.log | grep Doctrine) Thanks a lot!

  • How to limit the number of concurrent CGI script invocations in Apache 2.2?

    - by hsivonen
    How can I limit the number of concurrent CGI invocations in Apache 2.2.x? More specifically, my problem is this: I have Apache hosting a Bugzilla instance and other stuff on one server. There's very little legitimate concurrent use of Bugzilla. However, it's trivial to mount a Denial of Service attack on the whole server by ignoring robots.txt and simply fetching a lot of bug pages that fork a process and hit a database.

  • Server Hardware on the Desktop

    - by jcnnghm
    When I rebuild my desktop, I'm thinking of using server hardware instead of desktop hardware. I want to do this so I can easily add a lot of ECC memory (~20GB), and possibly more than one processor. I know that video hardware could be a problem, especially because I use 4 monitors. I should be fine with this, as long as I have two pci-e channels. Are there any downsides to doing this? Anything I'm not seeing?

  • palmtop tablets with Android?

    - by Stefano Borini
    I was looking for a WiFi enabled palmtop tablet with Android (to replace this indecent tablet I bought just one week ago from a well known trendy company). At the moment, I see a lot of phones, and the only tablet is the Archos 5, which is not available yet. Am I missing something ? Please note: no phones. Just tablets. And no Nokia. I'd love Nokia, but it's not available here.

  • Prefork or Worker MPM for amazon xlarge server?

    - by Netismine
    I'm trying to measure would it be better to have prefork or worker mpm apache module for the server I'm working on, which is Amazon X-Large 15 GB memory 8 EC2 Compute Units (4 virtual cores with 2 EC2 Compute Units each) and that will run a Magento website with about 50 active users at once. Site serves a lot of images and about 45 requests per page. Images sometimes hang, so it seems worker would be a better option? Thanks

    I have a couple of ebooks as PDFs with passwords, however my ebook reader (sony prs600) doesn't seem to support PDFs with passwords. What is the easiest of removing the password from a PDF (I know the password, which presumably helps a lot).

  • MySQL server installation problems (windows)

    - by waitinforatrain
    Hi guys, I'm trying to install some CMS software (Wiccle). I was using XAMPP's MySQL but was getting a lot of errors (the same configuration works on another machine) so thought I'd install MySQL Community Edition to see if the proplem was related to the MySQL server. When I install and run the MySQL Community Edition service, however, it only works with my XAMPP password, and contains the same tables as the XAMPP install. Is there a common local database file where the database and login info is stored? Any help appreciated

  • Shopping for a very compact and powerful workstation [closed]

    - by qdot
    I'm on the market for something small, size of an Mac Mini, could be heavier, that packs a lot of compute power - goal is to have a fast, known development machine at customer's site, but still easier to fly with than desktop-replacement laptops. If Mac Mini came with a quad-core i7, it would be my likely choice. Any other manufacturers to look at? Or perhaps a Mini can be upgraded beyond official specs?

  • Bringing TechNet licensed server into production

    - by David Heggie
    I am currently trialling an install of Windows Server 2008R2 + SQL Server 2008 R2 using license keys from my company's TechNet subscription. If the trial is successful, I'd like to bring the server into production as is (there's a lot of config needed for it that I don't want to repeat) so my question really is is it possible to change the Windows and SQL server licenses from TechNet ones to "proper" volume licenses and legally use the server in production? Or do I have to reinstall everything with volume licences?

  • Permit any user to mount any CIFS share

    - by A.K
    Essentially, I want the Ubuntu pre-10.10 behaviour back. The setuid method (see notes) does not work anymore. I search a lot on the Internet, but I haven't found a satisfying solution. I have read a solution that involves editing the sudoers file (ALL ALL=NOPASSWD:/sbin/mount.cifs). But then, the users would also be able to specify a directory as a mount-point they normally would not have access to, right? This is not what I want.

  • What is the most efficient way to scan in thousands of pictures? [closed]

    - by leora
    My parents have a number of really large albums and the pictures are starting to face in a lot of cases so we thought it would be a good idea to scan in all the pictures and move them to online albums. The issue is that the task is daunting given that there are thousands of pictures. Are there any services or ideas on how to scan in albums of pictures that won't take up hundreds of man hours for me?

  • Lots of dropped packages when tcpdumping on busy interface

    - by Frands Hansen
    My challenge I need to do tcpdumping of a lot of data - actually from 2 interfaces left in promiscuous mode that are able to see a lot of traffic. To sum it up Log all traffic in promiscuous mode from 2 interfaces Those interfaces are not assigned an IP address pcap files must be rotated per ~1G When 10 TB of files are stored, start truncating the oldest What I currently do Right now I use tcpdump like this: tcpdump -n -C 1000 -z /data/compress.sh -i any -w /data/livedump/capture.pcap $FILTER The $FILTER contains src/dst filters so that I can use -i any. The reason for this is, that I have two interfaces and I would like to run the dump in a single thread rather than two. compress.sh takes care of assigning tar to another CPU core, compress the data, give it a reasonable filename and move it to an archive location. I cannot specify two interfaces, thus I have chosen to use filters and dump from any interface. Right now, I do not do any housekeeping, but I plan on monitoring disk and when I have 100G left I will start wiping the oldest files - this should be fine. And now; my problem I see dropped packets. This is from a dump that has been running for a few hours and collected roughly 250 gigs of pcap files: 430083369 packets captured 430115470 packets received by filter 32057 packets dropped by kernel <-- This is my concern How can I avoid so many packets being dropped? These things I did already try or look at Changed the value of /proc/sys/net/core/rmem_max and /proc/sys/net/core/rmem_default which did indeed help - actually it took care of just around half of the dropped packets. I have also looked at gulp - the problem with gulp is, that it does not support multiple interfaces in one process and it gets angry if the interface does not have an IP address. Unfortunately, that is a deal breaker in my case. Next problem is, that when the traffic flows though a pipe, I cannot get the automatic rotation going. Getting one huge 10 TB file is not very efficient and I don't have a machine with 10TB+ RAM that I can run wireshark on, so that's out. Do you have any suggestions? Maybe even a better way of doing my traffic dump altogether.

  • Photoshop: left-handed copy/paste?

    - by Diodeus
    Being left-handed, I use the mouse in my left hand. In most applications I use CTRL+INSERT/SHIFT+INSERT to copy and paste (with my right hand). For some bone-headed reason, this is not supported in Photoshop, so I have to use right-click COPY sub-menus, which is a lot slower. Is there a way to configure Photoshop to use CTRL+INSERT to copy and SHIFT+INSERT to paste?

  • Is there an online identicon creator?

    - by wonsungi
    I thought the pictures associated with our profiles were automatically generated until they were manually changed. A lot of people have these cool identicons based on their IP address. How can I get my own identicon? I am looking for an online generator. Gravator does not seem to have any options to generate identicons. Edit: I will probably accept your answer if you just tell me how you made your identicon (and it did not involve downloading/installing stuff)

  • Where is the statusbar in Firefox 4? How do I get it back?

    - by lovinglinux
    Since version 4.0b7pre, there is no more statusbar in Firefox, which has been replaced by the new add-ons bar. The main problem is that a lot of users like me are missing some valuable information that was displayed in the statusbar on previous versions. For instance, when hovering a link the url is now displayed in the address bar and you can't see the entire address. Other information like which servers are being contacted when you load a page are no longer displayed.
