• How can an iPhone access another non-iPhone device over wireless or bluetooth?

  - by Tai Squared

  I'm trying to figure out if an iPhone can connect to another non-iPhone device over wireless or bluetooth and have seen conflicting information. Much of what I've found was before version 3.0 of the SDK came out, when it certainly wasn't possible. Looking at questions like this mention you can't connect to an arbitrary device unless if it's part of the "Works for iPhone" device. Do I need hardware that is part of this program? Looking through the Apple documentation, it mentions connecting two iPhones, not an iPhone to another Bluetooth device. Then there are articles like this that includes this quote ...and with the newly-announced "standard support" should allow file transfer between the iPhone and a computer, as well as between nearby iPhones Other questions mention Bonjour, and the Apple documentation talk about connecting to Bonjour devices, but can an iPhone connect to any Bonjour device? Does it have to have a wifi connection, or can it use Bluetooth? Even if I could use Bluetooth to connect to another device, it won't be available on first generation iPhones and iTouches, I believe. Is that correct? I'm thinking of an iPhone application that would need to communicate with other non-iPhone devices in the area, probably using Bluetooth, but possibly a direct wireless connection. What are the possibilities and limitations of this approach? Is it not possible to have an iPhone connect to an arbitrary Bluetooth device? Does the other device have to be on a wireless Bonjour network that? I'm trying to figure out if it's even possible for this to work or if it's not worth the effort.

• Stable ubuntu distribution for a broadcom bcm4313 wireless driver and an nvidia 630 graphics adapter

  - by Vivek Pradhan

  I have been trying to completely shift to ubuntu or a linux distro for almost 2 years now. I have tried all the ubuntu distros starting from 10.04 through 11.10, but there has always been some bugs with the display drivers or the wireless cards not being recognised and the additional drivers suggested from the ubuntu community not doing the trick always. I tried a lot to fix bugs, checked a lot of forums, launch pad, got some of them fixed, but could not really get a neat and complete ubuntu machine set up till now. Now I really like the whole open source community and the linux platform, my pc at home runs ubuntu 11.04 perfectly but there have been some glitches always with ubuntu on my laptop that has forced me to stick with windows only. Now I am currently on an hp dv6 laptop that has the broadcom bcm4313 wireless driver and the nvidia 630gtm graphics(optimus) driver. Now I tried to do some research on the support of these drivers in linux machines but could not get anywhere. So I would really appreciate if you guys could suggest some linux distro that I could use that has full support of these drivers or has stable bug fixes for these kind of issues. I tried precise pangolin (LTS) through a live CD but i still see a problem with wifi networks which is a little frustrating. Please help me find the perfect match for my laptop :P I would gladly provide any other information necessary.

• Old Lock Retrofitted for Wireless and Key-free Entry

  - by Jason Fitzpatrick

  What do you do if the old key your landlord gave you is poor fit for your apartment’s lock? If you’re the geeky sort, you build a wireless unlocking module to do the work for you. Instructables user Rybitski writes: The key to my apartment never worked quite right because it is a copy of a copy of a copy. I am fairly certain that the dead bolt is original to the building and the property manager seems to have lost the original key years ago. As a result unlocking the door was always a pain. Changing the lock wasn’t an option, but eliminating the need to use a key was. To that end, he built the device seen in the video above. An Arduino Uno drives a servo which in turn opens the deadbolt. The whole thing is controlled by a simple wireless key fob. Hit up the link below for the full build guide including code.

• How do I connect my NetXtreme BCM5755M Gigabit Ethernet PCI Express in y Dell latitude d630?

  - by Stanton.Sculpture

  Trying to get my 09:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5755M Gigabit Ethernet PCI Express (rev 02) working with my wifi.

I've tried sudo apt-get install b43-fwcutter firmware-b43-installer because it worked on a bunch of old Dell laptops that I converted over before, but it didn't work on this one. Is this driver even compatible with wifi? Please help.

• Wifi range issues and intermittent dropouts, Thinkpad Edge

  - by jimbo

  If I am more than a couple of metres from my access point (and I'm seeing this across various APs) with my newish Thinkpad Edge 15, running 10.10, the wifi performance becomes ... flaky. When this is happening, I see the following in dmesg, although I'm not sure if it's related: [ 2497.011099] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2502.012711] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2507.009254] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2512.008367] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2517.007467] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2522.006558] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2527.008157] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2532.007251] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2537.003838] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2542.005427] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2547.004496] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2552.003611] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded lspci -vvv has the following to say about my wireless adapter: 03:00.0 Network controller: Intel Corporation Centrino Wireless-N 1000 Subsystem: Intel Corporation Centrino Wireless-N 1000 BGN Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 49 Region 0: Memory at f0500000 (64-bit, non-prefetchable) [size=8K] Capabilities: <access denied> Kernel driver in use: iwlagn Kernel modules: iwlagn If I get within a couple of metres of the access point, I still see that output in dmesg, but the connection stabilises.

As ever let me know if there's other information that would help! Edit: I am using this machine in exactly the same locations I used my previous Thinkpad (T61) running various older versions of Ubuntu, so I definitely feel there is something wrong, rather me having unreasonable expectations of range!

• Can not access Internet (DNS names do not resolve) after update today

  - by Aras

  I have been using Precise for a few weeks now for work with no problem. Today, I am not able to access any website using either wired or wireless connections. I installed the updates today which included nautilus, xserver, and a new kernel (3.2.0-24). After restarting I no longer was able to browse the Internet using firefox or chrome. Trying to ping google in terminal gives ping: unknown host google.ca I have tried: Connecting to wireless or wired networks (both working on other machines) Restart the machine and boot with previous Kernel Manually configure opendns on my wired connection Restart the network and the laptop and the wireless card Without any success so far. I am not sure where to go next. Please let me know the cause of the issue or help me troubleshoot it. Note that the laptop does receive an ip address, and it can ping ip address of google.ca (74.125.127.94) but not the domain name, or any domain name for that matter. This system was upgraded from 11.10 to 12.04 more two weeks ago.

• Use Network-Manager to Connect to a wifi Access Point on the command-line

  - by Stefano Palazzo

  I'd like to connect to a wireless access point from the command-line. ideally, I'd only need the name of the AP. But the hardware-address would work as well. I know I can use nmcli to connect to a managed network connection, but in my case, the access point may not be configured for Network-Manager yet (See the difference between the output of nm-tool and nmcli con). Example output of nmcli: Auto pwln 3a3d62b1-bbdf-4f76-b4d2-c211fd5cfb03 802-11-wireless [...] Wired Network aa586921-accf-4932-98c4-c873c310f08e 802-3-ethernet [...] Cisco-UDP Uni 7f94847b-04dc-40b7-9955-5246fb77cc65 vpn [...] T-mobile (D1) 867f345a-cbbf-4bd4-b883-a5e5ae0932f0 gsm [...] Example output of nm-tool: State: connected - Device: eth1 [Auto pwln] ---------------------------------------------------- [...] Wireless Access Points (* = current AP) *pwln: Infra, [...], Freq 2472 MHz, Rate 54 Mb/s, Strength 80 WPA WPA2 WLAN: Infra, [...], Freq 2422 MHz, Rate 54 Mb/s, Strength 20 WPA WPA2 [...] How do I connect to an access point that may or may not be known to NM? Extra: Finding out if the connection needs a pass-phrase, and submitting it on the command-line as well would be great too (that is to say It'd be nice if network-manager wouldn't pop open any keyring dialogues or errors on the gui)

• Network Issues only on one network with a Broadcom BCM4312

  - by Ryan McClure

  My Ubuntu 11.10 laptop is having network connection issues...only on one network. I have a BCM4312 card and I'm using the proprietary driver. Whenever I connect to a network over wireless connection, I have no trouble except for one network. In my dorm, if I try to connect to the wireless network, it stays connected from anywhere to 30 seconds to 30 minutes before it will still be "connected" according to the indicator but there is no incoming/outgoing internet connection. This only happens in this building. Other networks with the same name at other buildings on my campus have no issue whatsoever. I took it to the tech department here and they keep claiming it's my laptop; but, if I can connect to other networks with absolutely no issues, why can't my laptop connect here? So, here's my question: Is it my laptop, or is it the network? As a side note, no one else that I know has issues on this network but one; she's running Windows 7 and I forget what kind of laptop it is. One of the people in my hall runs Ubuntu 12.04 and has no problem with the wireless. What do you all think of this?

• Just installed 13.04 and everything is fine except I cannot connect to the internet. Any thoughts?

  - by razorccatu

  I just installed Ubuntu 13.04 on my HP G62 laptop and the install went smoothly. I did the install off of a USB drive after trying ubuntu. While I was testing it, I connected to my Wireless with out issue and surfed a little. After the install, no wireless. I can still connect to my wireless network (at least it tells me I'm connected at full strength) but No servers can be found. I attempted to ping Google to no avail and I attempted to ping my router to no avail. I tried to then hard wire the machine and once again it told me that I was connected but I was not. When I ran dmesg, I got the following message: Warning: nss-myhostname is not installed. Changing the local hostname might make it unresolvabe. Please install nss-hostname! Is the hostname the issue? if so, how do I resolve it with out internet connection? If it's not the issue, how do I move forward? Thanks for any help. EDIT. I forgot to attach the image of my ifconfig if that might help.

• How to get Wifi Working Properly - I am Noob

  - by user287853

  I'm a noob to Ubuntu, but not computers. I installed a full version of Ubuntu version 12 whatever it is. I run it on a machine that has Win7/Win8 on another hard drive. My wireless adapter is some tiny USB stick I got on eBay - it works great in Windows, but I can't get it to work in Ubuntu. More precisely, Ubuntu is providing me a list (sometimes) of wireless networks in the area and when I try to connect to mine it just keeps password prompting me even though the one I use is correct. I looked over all the settings multiple times and don't believe there is anything in error regarding what it takes to connect to my network. So, I thought maybe it is a driver issue and came across NDIS. I thought I should try installing it, but I don't know how when I can't connect the Ubuntu machine to the Internet. I tried some commands to no avail. I have the Ubuntu installation disc and it shows a NDIS common and utils .deb files in there. Can someone out there help me out to get this wireless setup so I can get online?

• Cannot connect to Internet via Wifi

  - by lvogel

  I have a laptop that's currently configured as a dual-boot. The problem: I cannot connect to the Internet in the home wireless network through Ubuntu in the apartment where I currently live. The strange part: I can connect to it just fine through Windows (as right now), and I can use the Internet through Ubuntu on this computer with all the other wireless networks I have tried. The problem is only with this particular combination. The only possible explanations I can think of are either that this network is WPS, or that it's a driver problem--Vodafone router. The router 'sees' the computer--and it says it's connected; however, I keep getting prompted for a password, and I enter the key that works with Windows, but in Ubuntu it just keeps asking for it repeatedly, and I can't access the Internet. I don't have an ethernet cable at the moment, but if someone would be so kind as to ask me questions I will gladly answer, and if you have suggestions, I will do them--the only thing is, I am subletting this apartment from someone who is away on vacation, so I don't want to screw with the router settings unless I know what I'm doing! - I do not have Wicd - Yes, I have the router's information (key works in Windows) - Feedback of lshw says that the wireless card is Ultimate N Wifi Link 5300, vendor: Intel Corporation, physical id: 0 ,etc. The first two commands I was told to try work OK, but when I typed sudo ifconfig wlan0 essid ..... I got back 'essid: Unknown host' Would my question be better on the Ubuntu forums than here on AU?

• If I can ping my DB server, is my SQL Server connection guaranteed to work?

  - by Matt

  If I can ping my DB server, is my SQL Server connection guaranteed to work? I am using a default connection string in my code. My program runs fine locally but overseas sites are having issues and I am wondering if SQL might be using a TCP or UDP port that is still blocked. Here is the connection string "Data Source=xxxx.xxxx.com; Initial Catalog = xxxxx; User ID=xxxxx;password=xxxxx"

• Java: Sharing a connection pool accross other J2SE Apps...?

  - by Zombies

  So I have a connection pool setup. Which is great and all since I have an application that really needs it. However what I would like to know is if it is possible to share this connection pool with other J2SE apps? Would this even be worth it, as opposed to creating a connection pool based on each apps needs? If it would be prudent, how can I accomplish this?

• Can a stateless WCF service benefit from built-in database connection pooling?

  - by vladimir

  I understand that a typical .NET application that accesses a(n SQL Server) database doesn't have to do anything in particular in order to benefit from the connection pooling. Even if an application repeatedly opens and closes database connections, they do get pooled by the framework (assuming that things such as credentials do not change from call to call). My usage scenario seems to be a bit different. When my service gets instantiated, it opens a database connection once, does some work, closes the connection and returns the result. Then it gets torn down by the WCF, and the next incoming call creates a new instance of the service. In other words, my service gets instantiated per client call, as in [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]. The service accesses an SQL Server 2008 database. I'm using .NET framework 3.5 SP1. Does the connection pooling still work in this scenario, or I need to roll my own connection pool in form of a singleton or by some other means (IInstanceContextProvider?). I would rather avoid reinventing the wheel, if possible.

• How do I take advantage of Connection Pooling with Apache Active MQ?

  - by ScArcher2

  I'd like to know how to properly use connection pooling with Active MQ. Currently I have a Connection Factory that creates a new connection every time I want to send a message. I'd like to be able to pool Connections so I don't incur the overhead of connecting every time.
