  • NetworkManager refuses to manage my WLAN interface

    - by user104167
    I'm using Ubuntu 12.10 with Gnome 3.6 on a brand-new Samsung NP900X4C. The installer detected the wireless adapter, took in the SSID and WPA passphrase, wrote these into /etc/network/interfaces and connected perfectly. Once installation was finished I wanted to switch to using NetworkManager to manage the wireless adapter, since this is much more convenient than fiddling with /etc/network/interfaces every time I find a new hotspot. Therefore I edited /etc/NetworkManager/NetworkManager.conf to set: [ifupdown] managed=true When I rebooted NetworkManager, the problems started: - The NetworkManager tray applet changed from saying device not managed to device not ready - I lost all internet connectivity as wlan0 would not associate to the Access Point - if I set managed=false in NetworkManager.conf and restarted both NetworkManager and networking services from the command-line, the Gnome desktop "semi-crashed" and lost all its Window Decorations, the panel, the launcher and basically became unusable. However if I restart the computer completely after setting managed=false, wlan0 once again works perfectly.

  • Getting wifi working on 14.04

    - by user286114
    I have installed Ubuntu 14.04 on my laptop. When I plug in the ethernet cable the internet works fine, but I can't see any wireless network in the networking manager. The wifi switch is definitely on on my laptop! It's a Dell XPS M1330. I'm not sure what the network card is - how can I find out? nm-tool gives me this: NetworkManager Tool State: connected (global) - Device: eth0 [Wired connection 1] ------------------------------------------- Type: Wired Driver: tg3 State: connected Default: yes HW Address: 00:23:AE:28:FE:A2 Capabilities: Carrier Detect: yes Speed: 100 Mb/s Wired Properties Carrier: on IPv4 Settings: Address: 192.168.1.26 Prefix: 24 (255.255.255.0) Gateway: 192.168.1.254 DNS: 192.168.1.254

What do you suggest? keep on track on what experience I have or make u turn start a new path. Thanks

  • 3 Steps to Establishing an Internet Presence

    In today's World Wide Web, establishing an Internet presence could mean a number of things. From, starting a simple personal website, to setting up a profile on a social networking site, to starting a blog using any of the several hosted blog platform solutions. But if you're starting a home business - on or offline, establishing an Internet presence begins with creating a website for your business, where the introductions between potential customers and the products and/or services you offer take place. In many cases, this involves obtaining a domain name, getting reliable web hosting, and building your website.

  • What languages should I learn before I go to college? [closed]

    - by CLUEL3SS
    I've been working with PHP, MySQL, and some html for the past 3-4 years now just as a hobby. I'm only 19 and college is going to come soon, I want to go for Web and Software development and/or Network Security and Administration, I know the networking is a whole different ballpark, but as for programming, which languages do you suggest I get under my belt before college? I was thinking the C languages (C++, C#), Java, .NET; Should I learn any more Server Side Scripting languages? Python, Perl, Ruby? I used to be somewhat familiar with writing Java, but haven't written in Java in a good while, what would you suggest? Thanks!

  • What is the best .NET web development framework?

    - by tjjjohnson
    I'm looking for a framework to simplify the creation of a website with social networking features and plenty of custom functionality. I'm quite keen to use an ORM like nHibernate or similar for data access. Would DotNetNuke be a good choice? Or are there other options which are better. Added: I'm quite keen not to have to reinvent the wheel for the social network features like secure login, open id, friends etc.

  • Http requests / concurrency?

    - by maxp
    Say a website on my localhost takes about 3 seconds to do each request. This is fine, and as expected (as it is doing some fancy networking behind the scenes). However, if i open the same url in tabs (in firefox), then reload them all at the same time, it appears to load each page sequentially rather than all at the same time. What is this all about? Have tried it on windows server 2008 iis and windows 7 iis

  • Best FTP Objective-C wrapper for iPhone

    - by jamone
    I know you use the C based networking API to do FTP communication but I'd prefer to use something a little higher level. I've seen a few Objective-C based wrappers but I'm not sure what to use. I don't need that complex of FTP interaction. Its just the typical create/delete dirs, upload/download files... What do you recommend?

  • Should I use a recruiter?

    - by Dubs
    Knowing how to find a good job is an important part of being a programmer. I know it's a good idea to post my resume on different sites like Monster and Dice. I also know that networking is important. But, what I'd really like to know is how everyone feels about using a recruiter (aka headhunter). What are the pros and cons? Is it better to deal with a company directly? Thanks!

  • My iPhone app needs a persistent network connection...how to specify UIRequiredDeviceCapabilities?

    - by Greg Maletic
    I'm trying to set the UIRequiredDeviceCapabilities properties in my Info.plist file. My app requires a persistent network connection. If I look at the definition for the "wifi" key, it says: Include this key if your application requires access to the networking features of the device. So: does the "wifi" key indicate that I need WiFi, as the key name would suggest? Or does it mean that I simply need network access, as the key definition would suggest?
