  • D-LINK DIR-615 router keeps giving my wireless devices bad ip addresses

    - by mlsteeves
    I have a D-LINK DIR-615 router, and wired devices have no problem getting an IP, however; wireless devices end up with a 169.254.. address (subsequently, they cannot access the internet through the router). I have removed all wired connections from the router, so there is no other dhcp server running. I've also gone back to the store, and replaced it with another, thinking that maybe it was defective. According to the router, it gave 192.168.0.101 to the wireless device. According to the wireless device it got 169.254.67.71. I've tried both a laptop and an iPod Touch, both exhibit the same behaviour. Has anyone seen this type of behaviour, or have any ideas of stuff to try? NEW INFORMATION I looked at the logs on the router, and when the wireless device tries to connect, this is what is logged: Sep 10 18:13:39 UDHCPD sending OFFER of 192.168.0.111 Sep 10 18:13:31 UDHCPD sending OFFER of 192.168.0.111 Sep 10 18:13:26 UDHCPD sending OFFER of 192.168.0.111 Sep 10 18:13:23 UDHCPD sending OFFER of 192.168.0.111 Sep 10 18:13:21 UDHCPD sending OFFER of 192.168.0.111 I connected a computer directly to the router, and here is what it looks like: Sep 10 18:14:18 UDHCPD Inform: add_lease 192.168.0.110 Sep 10 18:14:14 UDHCPD sending ACK to 192.168.0.110 Sep 10 18:14:14 UDHCPD sending OFFER of 192.168.0.110 Not sure if that helps or not.

  • Wireless signal changes from strong to weak after connecting

    - by gibberish
    Router (primary AP) is a WRVS4400N, WAP (signal booster) is a WAP4410N. Problem: User is physically located within ten feet of WAP (200 feet from main wireless router). Signal is at 5 bars as user connects to wireless network. Within seconds, signal is at or below two bars and connection is poor. Background: Trying to solve problem of weak wireless signal in back offices. Desired result is for client laptops to automatically switch to the stronger signal. WAP is connected to network via Ethernet cable. WAP is set to AP mode (instead of Wireless Repeater mode) WAP does appear to boost signal. Using Windows 7 sys tray Connect To A Network applet, can observe signal boost as laptop approaches the WAP. Above-described problem happens to users located near or beyond the WAP. It does not happen to users in close proximity to the router. Secondary Question: If using WAP in AP Mode, do WAP and Router (primary AP) need to be on the same channel?

Show Notes Feature Interview James Gosling received a BSc in Computer Science from the University of Calgary, Canada in 1977. He received a PhD in Computer Science from Carnegie-Mellon University in 1983. The title of his thesis was "The Algebraic Manipulation of Constraints". He spent many years as a VP & Fellow at Sun Microsystems. He has built satellite data acquisition systems, a multiprocessor version of Unix, several compilers, mail systems and window managers. He has also built a WYSIWYG text editor, a constraint based drawing editor and a text editor called `Emacs' for Unix systems. At Sun his early activity was as lead engineer of the NeWS window system. He did the original design of the Java programming language and implemented its original compiler and virtual machine. He has been a contributor to the Real-Time Specification for Java, and a researcher at Sun labs where his primary interest was software development tools.     He then was the Chief Technology Officer of Sun's Developer Products Group and the CTO of Sun's Client Software Group. He briefly worked for Oracle after the acquisition of Sun. After a year off, he spent some time at Google and is now the chief software architect at Liquid Robotics where he spends his time writing software for the Waveglider, an autonomous ocean-going robot.

  • getting Internet connection sharing working in a slightly more complicated configuration

    - by tirichitirca t
    I have the following configuration: Computer A - Mac OSX 10.8.4, wireless & wired adapters Computer B - Windows 7 (64 bit), wireless & wired adapters, has internet connection via the wired adapter (ethernet) d-link wired/wireless router. Problem to solve: Connect from computer A to the internet through the wired connection of computer B. I tried the following: I set up a local network between A and B using the d-link router. The configuration is this: D-link router - 192.168.0.1 A - wired connection to the d-link router, static 192.168.0.101 (I could have used the wireless but I preferred the wired connection) B - wireless connection to the d-link router DHCP 192.168.0.102 (but I made sure it always gets the same address) B - wired connection to the internet using some address that begins with 10.x.y.z. In this configuration A can see B. I enabled ICS on the wired adapter of B. I set up the Gateway of A to point to B and DNS servers to point to the DNS servers specified for the 10.x.y.z address. It doesn't work, A goes only as far as B. It can ping the 10.x.y.z address of B though. I then found this article: http://terrybritton.com/windows-internet-connection-sharing-ics-not-working-with-linux-bridging-is-the-solution-916/. Terry is suggesting that a bridge should be defined on B between the two connections. I tried that but basically computer B is screwed as soon as I create the bridge. It can't connect to the internet anymore. It is as if the network bridge seems to think the traffic to the internet should go from the wired connection to the wireless and not the other way around. The other thing that puzzles me is the router itself. In general the router needs an internet address. In a normal configuration it is the router that gets the ip address and the internet traffic goes through the router. In my case I am not interested in that. So, any suggestions to get this working? I wouldn't shy away from using a commercial software but I would think windows 7 should allow me to do it. Thanks

    My colleague and esteemed JavaFX hacker Stephen Chin is currently on the road on his NightHacking Tour through Europe, geeking with toys and projects, hacking code, and interviewing Java luminaries along the way. You might know the guy on the left – James Gosling was the first stop of the tour. What’s more, you can follow live on UStream at each stop along the way. Very cool! To learn all about the NightHacking Tour, check here.  Stephen will swing past my place in Freiburg, Germany, on Saturday (Nov 3). We’ll be chatting about all the stuff that’s happening in the embedded space these days and play with the latest small Java – if the demo gods allow For the latest UStream schedule and past recordings, go here. And follow #nighthacking on Twitter. Cheers, – Terrence Filed under: Mobile & Embedded Tagged: embedded, Java, Java Embedded, nighthacking

  • Toolkit & Habits for Linux Network & System Administration [closed]

    - by slashmais
    I am tasked with the administration of a small office network as well as several workstations running mostly Debian and Ubuntu. There are two servers: one database & print-server, and one backup & file server. Being relatively new to this side of things, knowing enough to help myself to some degree on Linux, I would like to know what software tools and tasks/habits I can use/acquire to learn this field and be effective while doings so. I don't need to know what is the best, just what a newbie sys-admin can use as a starter-pack to learn and use as a base to grow into proper system administration. [edit] What I need is those few basic tools to start with, and the kind of things I need to do regularly, e.g.: which logs to check, when & what to monitor, the kind of 'right' place to start and to which I can ad as I need.

  • How to use java ee 6 @Resource annotation

    - by javamonkey79
    The java ee 6 api has an annotation @Resource with an attribute 'lookup', however, so does the java se 6 api (here). However, since java ee 6 is dependent on java se 6, it seems you can not get at the ee version of the annotation and the 'lookup' attribute. Is this a bug or is there some other way to use this annotation that I am missing. TIA

  • Java Play Mustache NPE Error

    - by zanedev
    We are getting a mustache play error in production (amazon linux EC2 AMI) but not in development (MACs) and we have tried upgrading the jvm, using the jdk instead, and changing from a tomcat deploy model to match our development environments as much as possible but nothing is working. Please any help would be greatly appreciated. We have lots of shared code in java and javascript using mustache and it would be a big deal to rewrite everything if we had to ditch mustache on the java side. 20:48:52,403 ERROR ~ @6al2dd0po Internal Server Error (500) for request GET /mystuff/people Execution exception (In {module:mustache-0.2}/app/play/modules/mustache/MustacheTags.java around line 32) NullPointerException occured : null play.exceptions.JavaExecutionException at play.templates.BaseTemplate.throwException(BaseTemplate.java:90) at play.templates.GroovyTemplate.internalRender(GroovyTemplate.java:257) at play.templates.Template.render(Template.java:26) at play.templates.GroovyTemplate.render(GroovyTemplate.java:187) at play.mvc.results.RenderTemplate.<init>(RenderTemplate.java:24) at play.mvc.Controller.renderTemplate(Controller.java:660) at play.mvc.Controller.renderTemplate(Controller.java:640) at play.mvc.Controller.render(Controller.java:695) at controllers.MyStuff.people(MyStuff.java:183) at play.mvc.ActionInvoker.invokeWithContinuation(ActionInvoker.java:548) at play.mvc.ActionInvoker.invoke(ActionInvoker.java:502) at play.mvc.ActionInvoker.invokeControllerMethod(ActionInvoker.java:478) at play.mvc.ActionInvoker.invokeControllerMethod(ActionInvoker.java:473) at play.mvc.ActionInvoker.invoke(ActionInvoker.java:161) at Invocation.HTTP Request(Play!)

  • Home networking - Wireless switch?

    - by gamers2000
    I currently have a Linksys WRT160N that has a couple wireless clients and a few wired clients. We are planning to switch from DSL to cable and unfortunately, there isn't a cable point in a location close to the wired clients (i.e. the new location of the router would be too far from the wired clients to lay Ethernet cables). Thus, I was wondering if there was a wireless switch of some sort in which it would be a standard Ethernet switch that would connect to my wireless network? (This is a home network,of course.)

  • Windows XP does not list WPA wireless networks

    - by Tomalak
    What can be the reason that Windows XP does not show WPA-encrypted wireless networks? The laptop I have problems with is an older model (Toshiba Satellite Pro 6100) with Windows XP SP3 on it, fresh install. The wireless network card in it is an Agere product that lists as "Toshiba Wireless LAN Mini PCI Card". The networks showed up perfectly before I first tried to connect to one (it was set to WPA2). The connection failed (the card supports WPA only), then something must have happend and Windows hides these networks now. A manually configured WPA setup via Windows' own wizard works, I'm using it right now. The network just won't show up in the list of available network on its own. I suspect that XP incorrectly set a flag somewhere that this network card does not support WPA. Is there such a flag, and if so, how can I change it back?

  • Netgear Wireless-n 150 wrn1000v2

    - by Jordan
    I'm not sure if this is the place to ask this question, move it if it's not. I'm trying to fix a wireless network. It only connects to a few devices and when it does work the connection is spotty. The router is a netgear wireless-n 150 wrn1000v2. Connecting to the router isn't a big problem, but connecting to the internet via WiFi is. I can't upgrade the firmware becuase it is from Comcast and it seems as though they only allow their versions of the firmware. I've monitored the network with wireshark and I see that the devices that are having trouble connecting are constantly asking "who is 192.168.1.1 tell 192.168.1.x" where x is the ip for the device. 192.168.1.1 is the router. This is from running wireshark on the wireless device. What does this mean. At this point I feel like buying a new router is the only option.

  • Setting up multiple wireless access points on same network

    - by SqlRyan
    I'd like to add wireless to my network, and I need multiple access points to cover the whole area. I'd like to set them up so that there's only one "wireless network" that the clients see, and it switches them as seamlessly as possible between access points as they wander around (if that's not possible, then at least have it so that they don't need to set up the security by hand on each one the first time, if possible). I've searched online, and there are quite a few sets of mixed instructions (same vs different SSID, frequency, does the security need to match exactly, etc.). Can somebody who has some experience doing this please let me know what they did? I imagine it's pretty simple, but there seems to be no clear cut "yes, you can do this" online, even though I know you can. I have a mid-size LAN with about 20 workstations and two Domain Controllers on it. Also, I'll be doing this with consumer wireless components, if it makes a difference, not enterprise-level components (ie. Linksys rather than Cisco).

  • Mac claims to have connected to wireless network, but hasn't

    - by Mick
    I am attempting to connect a new mac OSX 10.6.5 laptop to a wireless network (I am a windows expert but a mac novice). It used to connect without problem to the network when I had the security set to "64 bit wep". Now I have changed the security on my belkin router to "WPA-PSK (no server)". I have two PC's and an old mac connecting via the new security setting without problem. Now I have the problem that on the new mac, the wireless icon is indicating a good connection (5 dark bars). Also the network name has a tick next to it on the wireless drop down menu. But I can not view any websites. I can not even connect to the router by typing 192.168.2.1 into a browser address bar. Any ideas where I went wrong?

  • Driver choice for addressing ubuntu wireless card issues

    - by Holly
    Hello, this should be a relatively simple question. I'm attempting to get my windows wireless card to work with ubuntu, booted from my portable hard drive. This is the guide I'm attempting to follow is on help.ubuntu.com, /community/WifiDocs/Driver/Ndiswrapper My wireless card is a Broadcom Corporation BCM4318 AirForce One 54g 802.11g Wireless LAN Controller. My computer is an HP Pavilion Entertainment dv5 notebook, which came with Vista 64. I would like confirmation about which of the drivers I should use. At this point, I'm leaning towards Broadcom BCM4318 HP Pavilion zv6000, but I thought it best to ask advice before taking action. The drivers I have to chose from are listed on this page http://sourceforge.net/apps/mediawiki/ndiswrapper/index.php?title=Category:Broadcom Thanks! Holly

    - by n179911
    I have running Windows 7 on my hp laptop with 802.11n wifi adapter. Some times, I lost wireless internet connection. Under the 'Wireless Connection' when I click the notification area, it said 'my home network is 'connected'... But in the header 'currently Connected to' it said 'no internet access' instead of 'internet access' I can 'fix' my problem by going to the 'wireless connection' my home network, click 'disconnect' and then click 'connect'. And when it comes back up, it gets connected again. any idea how can i fix this problem? Thank you.
