  • Turn your laptop into a wireless Access Point with Windows 7!

    - by David Nudelman
    Windows 7 offers a very cool feature where you can connect multiple devices to any wired and wireless network connection (hotel, cable, 3G, UMTS, EDGE, WIFI, RJ45, Ethernet, etc.) by turning your own laptop into a wireless AP (Access Point) to relay those devices not directly connected to the internet. For this just enter these two commands to an elevated (right click on CMD.EXE, run as administrator): netsh wlan set hostednetwork mode=allow ssid=YOURFRIENDLYSSID key=SOMEPASSWORD netsh wlan start hostednetwork At this point, if Internet Connection Sharing (ICS) is setup, anyone can connect to your SoftAP (if they know the PWD of course) and the traffic will be sent through whatever adapter you want. You can actually bridge it across an entirely different adapter... or the same on a different Wifi LAN. A GUI to set this up can be downloaded for free here: http://www.connectify.me/

  • How to set up an ethernet and wireless network using /etc/network/interfaces?

    - by den-javamaniac
    Hi. Currently I have ethernet and wireless networks configured through a network manager (further NM) but it seems to be a bit buggy (I need a different MAC for ether which is never applied if using NM), so I would like to move all the network configs to interfaces file. I know (or can google for) configuration code, but I'm not sure how NM works and it looks like it overrides interface config. Please advice, how I can handle this issue. NOTE: I also would like to be able to locate and connect to various wireless networks but not sure how to do it.

  • Java Socket Connection is flooding network OR resulting in high ping

    - by user1461100
    i have a little problem with my java socket code. I'm writing an android client application which is sending data to a java multithreaded socket server on my pc through direct(!) wireless connection. It works fine but i want to improve it for mobile applications as it is very power consuming by now. When i remove two special lines in my code, the cpu usage of my mobile device (htc one x) is totally okay but then my connection seems to have high ping rates or something like that... Here is a server code snippet where i receive the clients data: while(true) { try { .... Object obj = in.readObject(); if(obj != null) { Class clazz = obj.getClass(); String className = clazz.getName(); if(className.equals("java.lang.String")) { String cmd = (String)obj; if(cmd.equals("dc")) { System.out.println("Client "+id+" disconnected!"); Server.connectedClients[id-1] = false; break; } if(cmd.substring(0,1).equals("!")) { robot.keyRelease(PlayerEnum.getKey(cmd,id)); } else { robot.keyPress(PlayerEnum.getKey(cmd,id)); } } } } catch .... Heres the client part, where i send my data in a while loop: private void networking() { try { if(client != null) { .... out.writeObject(sendQueue.poll()); .... } } catch .... when i write it this why, i send data everytime the while loop gets executed.. when sendQueue is empty, a null "Object" will be send. this results in "high" network traffic and in "high" cpu usage. BUT: all send comments are received nearly immediately. when i change the code to following: while(true) ... if(sendQueue.peek() != null) { out.writeObject(sendQueue.poll()); } ... the cpu usage is totally okay but i'm getting some laggs.. the commands do not arrive fast enough.. as i said, it works fine (besides cpu usage) if i'm sending data(with that null objects) every while execution. but i'm sure that this is very rough coding style because i'm kind of flooding the network. any hints? what am i doing wrong?? Thanks for your Help! Sincerly yours, maaft

  • Is it possible to use multi keyboards with multi keyboard layouts simultaneously?

    - by mono
    Considering to switch to dvorak layout, but this terminal is used by multi users as the same user account. It is unacceptable to ask all people to switch layout, plus it is hard to use dvorak layout with a keyboard qwerty-ly labeled. But there are spare (USB,qwerty) keyboards, so if I plug another keyboard in and be able to use multi layouts on different psyical keyboard simultaneously (I will rearrange letters on keys), the problem get solved. solution for either windows or linux is fine. anyway thanks all.

  • Basic connectivity issues between Win 7 and XP mixed wired/wireless network.

    - by Pulse
    Setup: Windows 7 x64 Ultimate desktop hard wired to Asus WL500gp router (WL500gpv2-1.9.2.7-d-r1445 firmware) Several Bridged VirtualBox VM's running XP, 7, ubuntu server 10.04, Mint 9 and SuSE 11.2 Win XP Pro SP3 notebook with D-Link Airplus wireless network card. No firewall or other security software currently running on either platform (at least for the duration of the test) Situation: Router is acting DHCP server Clients are receiving correct addresses and additional parameters Internet connectivity is available from all clients Windows 7 sharing is set to Network type = work (not home group) NetBT is disabled on all clients using smb over TCP What I can do: I can ping the router and internet addresses from the wireless XP notebook I can ping the Win 7 desktop and any VM from the XP wireless notebook I can ping all devices from the router All VM's and 7 can ping each other and the router as well as Internet addresses What I can't do: I cannot ping the XP wireless notebook from either The Win 7 desktop or the VM's it alwats returns a destination host unreachable. Tracert resolves the name or the XP notebook but also returns a destination host unreachable. From the above it would seem that something is blocking connectivity in a single direction (from the Win 7 box to the Win XP notebook) only but the router can ping the XP notebook. Some fresh input would be most welcome, as this is beginning to drive me batty. Thanks

  • Ericsson f3507g WWAN (3G Broadband) and AT commands

    - by JD
    I have a lenovo x200t tablet with WWAN built into it. I'm trying to connect to the internet using AT commands and a C# program which I am making so that the program can connect to the net and upload information on demand. I don't want to use Lenovo's "Access Connections" as it is too complicated for the end user. So far I have been able to use terminal to turn the card on and off, ring landlines and send SMS messages. However I can't seem to access the internet using it. I could access the net through it before I removed "Access Connections" software/bloatware. The commands I am using to try and access the net are: Connect on COM7 to the modem Send initialisation string "AT+CFUN=1" Send AT*ENAP=1,1 as suggested here (http://www.thinkwiki.org/wiki/Ericsson%5FF3507g%5FMobile%5FBroadband%5FModule) Windows says it is "Identifying" the network and a yellow exclamation mark appears on the networking icon in the task bar, but the connection fails and drops off. An IP is assigned to the "Local Area Connection 2" of 169.254.1.192 with a subnet of 255.255.0.0 - no gateway or DNS. Definately no net connection... Anyone got any ideas?

  • decoding 802.11 b

    - by stan
    I have a raw grabbed data from spectrometer that was working on wifi (802.11b) channel 6. (two laptops in ad-hoc ping each other). I would like to decode this data in matlab. I see them as complex vector with 4.6 mln of complex samples. I see their spectrum quite nice. I am looking document a bit less complicated as IEEE 802.11 standard (which I have). I can share measurement data to other people.

  • Vehicle 2 Vehicle Communication Questions

    - by pinnacler
    I have a rare opportunity to meet the man in charge of implementing vehicle 2 vehicle communication for the US Department of Transportation with 2 others in a few hours. Do YOU have any questions for him? I know this is a little outside the normal, but this is a 'reverse' thread and I felt he has some great knowledge on the subject that I want to share with this community. I'll post his answers later today to his questions. Ask about V2V implementation, privacy issues, use cases, or if you've thought of a great way to use V2V and want me to share it with him, he can at least think about it. He is in charge of panel that creates the standard. Or anything else...

  • Verizon SongID - How is it programmed?

    - by CheeseConQueso
    For anyone not familiar with Verizon's SongID program, it is a free application downloadable through Verizon's VCast network. It listens to a song for 10 seconds at any point during the song and then sends this data to some all-knowing algorithmic beast that chews it up and sends you back all the ID3 tags (artist, album, song, etc...) The first two parts and last part are straightforward, but what goes on during the processing after the recorded sound is sent? I figure it must take the sound file (what format?), parse it (how? with what?) for some key identifiers (what are these? regular attributes of wave functions? phase/shift/amplitude/etc), and check it against a database. Everything I find online about how this works is something generic like what I typed above. From audiotag.info This service is based on a sophisticated audio recognition algorithm combining advanced audio fingerprinting technology and a large songs' database. When you upload an audio file, it is being analyzed by an audio engine. During the analysis its audio “fingerprint” is extracted and identified by comparing it to the music database. At the completion of this recognition process, information about songs with their matching probabilities are displayed on screen.

  • Voting software with remote units - architectural questions

    - by David Neale
    I'm looking at designing some software that registers live votes (let's say A,B,C or D). The vote needs to be picked up and processed by a .NET engine. The remote voting units should be as small as possible. What form of data transmission should be used for the voting? The data is obviously very simple but there is a need to make sure each unit can only vote once per question. How would the data be received by the computer running the software?

  • Gobi 2000 WWAN Adapter C#.net SDK

    - by jonhilt
    We have some software running on Windows 7 on a mobile device (Panasonic Toughbook) which needs to initiate a 3g connection to download data. The WWAn adapter in question is a Gobi 2000. Is there any way of controlling the adapter direct from .net or should we fall back on Windows to initiate the connection as required (battery life is important).

  • Verizon Fivespot firewall exceptions

    - by Patrick
    I have a Verizon Fivespot Wi-Fi router and am having issues connecting to the computer that uses it to get on the internet. I am able to connect to the Fivespot admin pages remotely and I am able to connect to the internet from the computer behind the Fivespot. I've tried asking this on superuser but have gotten nothing, I figure this is pertinent to programmers working on remote computers as well. There are two sections pertinent to this issue, Port Filtering And, Port Forwarding I've tried each individually and both together but cannot access anything through the router except for the admin page. I am trying to connect through SSH on Port 22 to an Ubuntu 10.04 box over wifi. I have called Verizon Tech Support but they were unhelpful, the person essentially read what it says on each screen without any elaboration. Any help is greatly appreciated!

  • Sending a Java object from my Android phone to my Computer

    - by TehGoose
    Hi, I was wondering what the simplest program for sending an object from my Andriod phone to my computer wirelessly (via LAN) would be. I have created Java RMI programs with a server and multiple clients, so I have a grasp of the concept. However with android I'm just not sure where to start. What I am aiming to do is send some sort of information (could simply be text) to my computer and my computer will do an action. I have the GUI interface's and the actions to be carried out all worked out, just the sending of some sort of information is getting me. Could anyone help me out?

  • Can I run Linux on the HP Mini from Verizon Wireless, with a built-in 3G modem, and connect using the built in modem?

    - by Parker
    I apologize if my question made little sense, I am very tired at the moment. Anyway, Recently I purchases the HP Mini from Verizon Wireless. It runs on the Intel Atom processor and came with Windows 7 Starter Edition, which is quite possibly the worst and most restrictive OS I have ever used. I plan on installing CRUX, after doing a little research on minimal, free, Linux operating systems, as I am working on web programming using Python, among other things. My only worry is that, because my HP Mini uses a built in wireless card (and I have no wifi connection, only a 3G connection) that has a "mobile access" connection to Verizon wireless, I am not sure if after installing CRUX that I would still be able to connect using this option. I have never used Linux before, and am hoping this will work. So if anybody has experience with this...please answer, can I connect to vzw 3G with linux, using an internal mobile access card...

  • Wireless WAN (WWAN) on a Lenovo T500 - built-in or do I need a WWAN modem?

    - by Justin Grant
    I use a Lenovo ThinkPad 2055-3AU at work and I want to get a Wireless WAN data plan with a local mobile telecom provider. I've read conflicting reports online about whether my system is "WWAN-ready" or not. How can I find out which wireless WAN providers (if any) my system can support without buying a separate modem? I looked through Device Manager for anything resembling a WWAN device and didn't see anything, but I also wiped the machine when I bought it and clean-installed Windows 7 with only out-of-the-box Windows and Windows-Update drivers, so it's possible that the device is there but the drivers aren't installed. FWIW, the support page at http://www-307.ibm.com/pc/support/site.wss/quickPath.do?quickPathEntry=20553AU does not specfically list anything about Wireless WAN.

  • How can a Virtualbox host connect to a guest VM when host wireless is disabled / host Ethernet cable is unplugged?

    - by uloBasEI
    I have a Virtualbox VM running on a computer connected to Internet via an Ethernet cable. The guest has a network adapter attached to a NAT. 2 ports (22 and 80) are forwarded so that the host can access them respectively on localhost:2222 and localhost:8080. When the Ethernet cable is plugged, both machine (host and guest) can access Internet and the host can access the SSH server/Webserver which ports are forwarded. When I unplug the Ethernet cable from the host, the host can not access the SSH server/Webserver of the guest anymore. Same situation with a Laptop connected to Internet via wireless when I disable the wireless adapter or set a wrong WPA key. My question is: is there a workaround for the host to access the guest services even if its Ethernet cable is unplugged / wireless is not available?
