  • Intel Wireless 4965AGN not achieving N throughput when connected to an Airport Express N network

    - by BenA
    I have an Intel Wireless WiFi Link 4965AGN adaptor in my laptop (HP Pavillion dv2000 series) which is connecting to a 5Ghz-only 802.11n network provided by an Apple Airport Express. The network is using WPA2 encryption. My desktop is also connected the Airport, via a Linksys WUSB600N USB adaptor. Both are running with the latest drivers, and the Airport is running the latest firmware. The Airport is also configured to use wide channels. The problem I have is that I never get throughput above 4MB/s when transferring files between the two machines. Even a pessimistic calculation shows a 270Mbps network as being capable of transfer rates at well above 10MB/s. I'm pretty sure I've isolated the issue to being the Intel adaptor, as wiring the desktop to the AP, and using the Linksys adaptor on the laptop immediately yielded speeds limited by the 100MB/s ethernet connection. I know that 802.11n is still a draft standard, and so mixing kit from different manufacturers can easily lead to poor results, but I was just wondering if anybody else out there has had success with this Intel adaptor on an N network? Or even better, connecting it to an Airport Express? Can anybody give me any advice on how to troubleshoot this issue? I should also mention that the Airport Express doesn't allow you to manually specify channels when running in N mode, and that I've been able to rule out interference from other Wireless LANs by scanning. There aren't any other 5GHz networks in my area. All ideas welcome! Update: A while later, I've just updated to the most recent drivers for both the Intel chip in the laptop, and the USB adaptor. Unfortunately this hasn't improved things :(. If anybody has any advice it would be be gratefully received.

  • Is there really a need for encryption to have true wireless security? [closed]

    - by Cawas
    I welcome better key-wording here, both on tags and title. I'm trying to conceive a free, open and secure network environment that would work anywhere, from big enterprises to small home networks of just 1 machine. I think since wireless Access Points are the most, if not only, true weak point of a Local Area Network (let's not consider every other security aspect of having internet) there would be basically two points to consider here: Having an open AP for anyone to use the internet through Leaving the whole LAN also open for guests to be able to easily read (only) files on it, and even a place to drop files on Considering these two aspects, once everything is done properly... What's the most secure option between having that, or having just an encrypted password-protected wifi? Of course "both" would seem "more secure". But it shouldn't actually be anything substantial. That's the question, but I think it may need more elaborating on. If you don't think so, please feel free to skip the next (long) part. Elaborating more on the two aspects ... I've always had the feeling using any kind of the so called "wireless security" methods is actually a bad design. I'm talking mostly about encrypting and pass-phrasing (which are actually two different concepts), since I won't even consider hiding SSID and mac filtering. I understand it's a natural way of thinking. With cable networking nobody can access the network unless they have access to the physical cable, so you're "secure" in the physical way. In a way, encrypting is for wireless what building walls is for the cables. And giving pass-phrases would be adding a door with a key. But the cabling without encryption is also insecure. If someone plugin all the data is right there. So, while I can see the use for encrypting data, I don't think it's a security measure in wireless networks. It's wasting resources for too little gain. I believe we should encrypt only sensitive data regardless of wires. That's already done with HTTPS, so I don't really need to encrypt my torrents, for instance. They're torrents, they are meant to be freely shared! As for using passwords, they should be added to the users, always. Not to wifi. For securing files, truly, best solution is backup. Sure all that doesn't happen that often, but I won't consider the most situations where people just don't care. I think there are enough situations where we actually use passwords on our OS users, so let's go with that in mind. I keep promoting the Fonera concept as an instance. It opens up a free wifi port, if you choose so, and anyone can connect to the internet through that, without having any access to your LAN. It also uses a QoS which will never let your bandwidth drop from that public usage. That's security, and it's open. But it's lacking the second aspect. I'll probably be bashed for promoting the non-usage of WPA 2 with AES or whatever, but I wanted to know from more experienced (super) users out there: what do you think?

  • Play Halo on the Xbox360 Arcade

    - by Jeremy Rudd
    I'm looking at purchasing a Xbox360 because I've wanted to catch up with the Halo trilogy. Does the cheap Arcade edition console support Halo 2 Halo 3? Halo Wars? Would I be able to save my game progress in single player? Would I be able to play online in typical maps? General questions: Would I be able to play games using the DVD drive or do I have to download everything? Does the tiny HDD hurt even if I don't download any games, trailers or music? Are there any other differences in comparison to the Xbox360 Pro? I have a regular TV that uses the composite cable, so I don't need the HDTV support in the Pro edition.

  • Why can't I reconnect to my Philips SHB9000 bluetooth headset?

    - by Thomas Eyde
    This is so annoying. When I connected my Philips SHB9000 bluetooth to my Windows 7 (64 bit) for the very first time, it worked well. I had to manually change the default playback device, but otherwise it worked. Then, when I start up my computer from standby, it's nearly random when I can reconnect or not. My last option is to remove the bluetooth device and reconnect it. But now, even that doesn't work. The sad thing is, this used to work better on Windows 7 beta. Windows Update has a new driver which fails to install. Searching for this driver yields nothing. I thought all vendors had an official site for their drivers? Well, Philips seems to have none. If there is no answer to this problem, my advice is to NOT buy this headset. It's good looking, the sound is nice, but what need do we have from that if we can't use the bloody device?

  • Spoofing UserAgent in Opera

    - by PoweRoy
    I'm trying to spoof Opera (under linux) to be an other browser, in this case iPad for some testing purposes. Now I know sites can check which browser is accessing the using for example in PHP $useragent = $_SERVER['HTTP_USER_AGENT']; and in javascript navigator.userAgent (or navigator.platform). In firefox you can use an addon to easily switch your useragent and other relevant information, but in Opera it seems it bit hard to do. First in opera.ini you can do: [User Agent] Spoof UserAgent ID=1 But this is limited to a predefined list of UserAgents. No room for custom ones. Also in opera.ini [ISP] Id=iPad This will add iPad to the User Agent of Opera. It's a start and works most of the time on the sites. In opera.ini you can set a 'User JavaScript file' to load a custom JavaScript file before loading a website: [User Prefs] User JavaScript File=/opera_dir/userjs/load.js In load.js you can do: navigator.userAgent = "Mozilla/5.0 (iPad; U; CPU OS 3_2 like Mac OS X; en-us) AppleWebKit/531.21.10 (KHTML, like Gecko) Version/4.0.4 Mobile/7B334b Safari/531.21.10" Because this file gets executed before loading the website I can modify the UserAgent, but this won't work when a site is checking the UserAgent via PHP, but it works for sites checking with Javascript) So here's my question: is there another way of spoofing a complete custom UserAgent?

  • How to overcome Local Group Policy Editor's 1023 character limit?

    - by Louis
    I want to reorder the SSL Cipher Suite Order applied as part of KB2919355, prioritizing the forward secrecy suites above all else. Trying to do this with gpedit at Computer Configuration Administrative Templates Network SSL Configuration Settings SSL Cipher Suite Order is a problem because the new list goes over the tool's character limit. Is there anyway to overcome this limit so I don't have to keep the current priority or omit something from the list?

  • Motherboard wiring

    - by ML
    I am putting a new motherboard in a chenbro chasis and I dont get how to plugin the wires for powerSW resetSW, etc. It is a SuperMicro P4DP6 motherboard. ** I cant post an image yet, but here is a long to the spot on the mobo where this goes: http://andrewslack.info/mobo.png The powerSW lead is a green and white wire. I have the wire for PowerSW in place as the white wire ground and I have tried the reverse even (green to ground). The wire is covering Pin 1 and 2 in the diagram And I press the power button on the machine and nothing happens. It worked before I replaced the motherboard, the 24-pin ATX power leas is connected as well as the 2dn 6-pin optional power. Thoughts?

  • TTY Resolution in Xubuntu 9.10

    - by Zurahn
    I've exhausted my ability to search through Google for this, so I'm giving it a go here. What I'm trying to do is increase the resolution (or decrease the font size) in the TTY terminals. Xubuntu 9.10 uses GRUB2, and everywhere I can find directs me to edit the /etc/default/grub File in order to add vga=XXX to the GRUB_CMDLINE_LINUX value, and this simply doesn't work. Out of endless fiddling with the file, nothing ever seems to change. On my Netbook running an earlier version, I had success with this command dpkg-reconfigure console-setup But once again it yields no change. Got any ideas?

  • 3 Monitors powered from a Nvidia fx580

    - by user26067
    I have a NVidia FX580 card in a Dell Precision T1500. The outputs of the back of the card are DVI and 2x displayport. I tried to run 3 screens from the DVI + 2x displayport to dvi adaptors, but the card won't have it... It'll only run 2 of these screens at the same time. http://www.nvidia.com/object/product_quadro_fx_580_us.html says; **Display Support:** Dual Link DVI-I 1 DisplayPort 2 # of Digital Outputs 3 ( 2 out of 3 active at a time ) # of Analog Outputs 1 To me this reads that it will be able to power 2xdvi monitors and 1xvga monitor. Anyone care to confirm or speculate?

  • How to connect two monitors to a macbook pro?

    - by CIRK
    I have a 13" macbook pro, and I need much more space right now, so I decided to buy two smaller monitors. (these from LG). But I don't really know how will I connect them. I've seen some products like this Diamond BVU195, but it's not currently in stores in my country. I've found these Equip 128450 USB 2.0 Display Adapter DELOCK USB 2.0 to DVI/VGA/HDMI Adapter The second one looks pretty cool, but it says that Windows is a system requirement or what, so I'm not sure if it will work with mac os x? So how did you connected multiple monitors to you mac, and are these adapters the best choices, if yes then is there an OS independent one?

  • Why is usable RAM less than total RAM?

    - by D Connors
    My girlfriend bought a laptop last week. It's a core 2 duo with 4 GB We installed vista 64bit, and one of the first things we did was right click on "My computer" to see gthe properties. Immediately we noticed something strange about her RAM, the line said: Installed memory (RAM): 4,00 GB (3,68 GB usable) I told her not to worry, thinking it must be something about the laptop hardware (considering her vista installation came from the same DVD as mine, and I never noticed anything like that on my 4 GB desktop). One hour ago, it got worse. We looked at Properties again, and it now says: Installed memory (RAM): 4,00 GB (2,98 GB usable) What does that mean? Are those 1,02 GB missing or being used by the system? EDIT: There is a possibility that the sytem information is wrong. I just noticed that it reports an intel T6500 processor, when it's actually a T6400. How can I find out how much RAM is really available to the system? EDIT2: Checking the resource monitors, it says 1003 MB are reserved for the hardware. Is that good or bad? Thanks

  • Recommended ADSL/ADSL2 router that supports PPTP VPN dial-out, 802.11n and gigabit ethernet?

    - by Throlkim
    I'm looking for a new router to provide a VPN tunnel for my home network. My plan is to pass all internet traffic over a PPTP VPN provided by the router, which should ensure that the connection stays alive and only passes traffic over that protocol. I'm normally quite a fan of Draytek routers, and their 2710n does seem to feature VPN dial-out but it lacks Gigabit ports (though I can make do with that if the VPN support is good enough). Has anyone got any suggestions or personal experience in a similar setup? I'm happy to consider anything that supports dd-wrt (as I believe that supports VPN-out, though I may be wrong). Bonus points for models available in the UK.

  • Windows 7 replacement of Vista's Windows Meeting Space

    - by Jason Pearce
    Microsoft Vista came with a free collaboration tool called Windows Meeting Space, which is not included in Windows 7 Enterprise nor can I find a stand alone link to download. Is there a similar tool included in Windows 7 that I'm missing or a replacement Microsoft product (perhaps Microsoft SharedView) that you would recommend? Ideally a tool that is compatabile with our existing Vista Windows Meeting Space users.

  • Disable SSD in ASUS 900 running Ubuntu 9.10

    - by ashays
    Recently I managed to completely mess up my ASUS 900, but I have no immediate desire to upgrade since it's only my travel laptop (and I'm waiting for a few months to see if anything interesting comes out). For now, though, I've hit an interesting problem. The 4GB SSD that is soldered onto the motherboard is broken. Since it's soldered on, there's really no hope of replacing it (I believe), so I've been solely running off the 16GB that is inserted into the mini pci-e slot. But since it can't read from the SSD it keeps giving me an error every time it tries to boot and read the ssd. Is there any way to either force Ubuntu to not check the drives on boot or disable the drive altogether, so that I don't have to sit through a 5 minute boot process each time I want to use the computer?

  • No network upsets gnome

    - by Darren Cook
    An issue that has been bothering me for over a year now. My notebook, running ubuntu 10.04, is almost all the time using a wired connection, with static IP address. And a remote DNS server. Network is configured with entries in /etc/network/interfaces and /etc/resolv.conf, rather than whatever the gnome UI tool was (*) But if I'm out, or simply unplug the network cable, a few things get weird. Specifically the gnome-panel stops working - it is still there, but isn't updating. And opening a nautilus window (e.g. to look at files on the local disk) has huge time-outs. By that I mean it will not open the window for something like 30 or 60 seconds; but when it does finally open it I can see the files and it is perfectly usable. Everything else works fine, alt-tab between windows, etc. I use the commandline to find the pid of gnome-panel, kill it, wait a couple of seconds, and it opens up a fresh panel which is normally usable. (Something like 10 minutes later it will have locked/crashed again; the same for the nautilus windows.) I'm guessing this is a DNS issue? Would setting up a local DNS server help? Guess number 2 was related to having a file server mount (samba, though running on another linux box), and symbolic links to files and directories on that file server on my desktop. My question is a bit vague... Does anyone recognize these symptoms, and have a suggestion? Or do you have some troubleshooting suggestions for narrowing down the problem? My /etc/hosts: 127.0.0.1 localhost 127.0.1.1 myhost # The following lines are desirable for IPv6 capable hosts ::1 localhost ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts 127.0.0.1 testsite.local #Other test website URLs here UPDATE: Some timings to open some desktop folder icons. This is after pulling out the network cable. A sub-directory of the desktop took 23 secs to open up. Content appears immediately (just 8 files, it has no further subdirectories). The home directory icon took 12 seconds to open up, but then took about 30 seconds for the files to appear. I closed it and tried again. This time it took 18 seconds to open up, but then 70 seconds before anything appeared. *: I couldn't work out how to use the gnome network tool for my needs, which include 3-4 static IPs for testing virtual hosts locally.
