Cannot connect to the internet using wireless, but dhcpcd passes...

Thanks for reading this in advance
So, I'm trying Arch Linux (going from XP/Ubuntu) on my desktop since all my friends at the university have been migrating to Arch, and even I loved the concept, and even installed it on a VirtualBox without problems.
Problem is I don't have a network card in my desktop, only a wireless one. So I NEED to get this one working. Ubuntu 9.04 delivered support for this card (SMC EZ-Connect USB 2.0 blabla, I'll save you on the details) so I tried Arch and after a LOT of googling and help from a friend, I managed to build a pkg to install the wireless firmware that was lacking to the p54usb module, and finally my wireless card was detected and appeared in ifconfig/iwconfig
However, after doing all the steps in the Arch Linux Begginer's Guide for configuring wireless, when I get to the last step (after using "dhcpcd wlan0" to acquire the IP from my wireless router, with sucess) that involves pinging just to test the connection, it fails. Unknown host. I've tryed almost everything and don't know the problem...
I'll post some of the details here from the commands I've used.

Windows 8.1 laptop cannot connect to the internet using USB Mobile Broadband stick.

I bought a new laptop and it came with Windows 8.1 installed. Well, things worked perfectly until I wanted to connect to the internet using my mobile broadband USB stick. I installed the software that came with the stick, and my laptop recognize
the stick but I still cant connect to the internet. The stick workes perfect in my Windows 7 and Windows 8 laptops, but IT DONT CONNECT WITH MY WINDOWS 8.1 LAPTOP. What can I do to troubleshoot this???
HOPE I AM SPECIFIC ENOUGH THOU...

The PC Repair Guy,
If you haven't already, verify that you can connect to the internet through some other means such as Wi-Fi or Ethernet with your laptop to rule out any network setting issues. If you are able to connect successfully to the internet, use that opportunity
to make sure you have
Windows 8.1 Update installed as well as any other applicable updates your laptop may require.
You may also want to check the
Windows Compatibility Center to make sure that your device is compatible with Windows 8.1.
Another possibility is that the driver your laptop is installing for the device isn't the correct one. Check the device manufacturer's site for the most up to date driver they have available for Windows 8.1.
Hope this helps!

Cannot connect to the internet using Cellular Data after iOS 6.0.1 update

While installing the iOS 6.1 update for my iPhone 4, I encountered an issue and had to restore it. Since completing the restore, I am only able to use a wifi connection to connect to the internet (apps not working when wifi isn't available, not even iMessage or safari - "Safari cannot open the page because it could not connect to the server"), although I have a mobile internet plan with my carrier. I also tried resetting the phone to its factory settings, but that didin't solve anything. Did any of you encounter this problem? How can I solve it?

Phone restart > if that doesn't work then do a reset of the settings. Full restore would be the last option.

NB200 Can connect to wireless networks, but cannot connect to the internet

I have been able to connect my Win XP netbook to my secure wireless network at home, other people's networks and public networks like the library and McDonalds. This week I'm away from home and discovered that while I can still connect to a number of different wireless networks, I cannot connect to the internet using Internet Explorer.
I've had this problem once before and fixed it by reinstalling Windows XP and all my other software. I have no idea why it has happened again. I'm hoping for a less drastic solution to the problem..?

Hi Nakia,
> I cannot connect to the internet using Internet Explorer.
Have you tested other browsers like Mozilla Firefox and does this work?
As MasterG wrote try to renew the IP address using the commend line.
Last week I had a similar problem and I could solve it by updating the WLAN driver. Just remove the driver, restart the notebook and install the newest one. :)

I have downloaded the new update for Firefox 3.6 and now cannot connect to the internet. I've checked my firewall and have uninstalled and reinstalled firefox, but nothing works.

After installing the new update for Firefox 3.6, no matter what I do, I cannot connect to the internet using Firefox. I can get on the internet using my other browsers (Google Chrome and Internet Explorer), so Firefox is the only one that doesn't work. I have already checked my firewall and have added and removed Firefox from my firewall to no avail. I've also already uninstalled and reinstalled Firefox, but so far it hasn't helped.

I have already tried removing firefox from my firewall. Even when I do that, my firewall doesn't detect firefox and prompt me to add it. And when I manually add it, it still doesn't work anyways. I've already tried the link as well, but it has been unhelpful. :/
I'm not sure if it matters, but a few weeks before this, I did download Microsoft Security Essentials.

How to restart base station from airport utility? I used to be able to do it remotely
I currently use a Mac Pro 10.8.4 and have a time machine for wireless 6.3 (630.34). Sometimes I cannot connect to the internet and use network preferences to diagnose the issue. This results in being told to restart the wireless. The airport utility includes the drop down option of restarting but is not clickable so I can't choose it.
With my prior macbook and same time capsule, etc if i had problems connecting to the internet I would run network diagnostics to help out. This included clicking on the airport utility ---> base station --> restart. This worked most of the time.
Bottom line, is there something I am missing in not being able to restart the wi-fi remotely? ]
Thanks in advance

You are likely forgetting a step.
Open AirPort Utility
Click on the Time Capsule icon
Click Edit in the small window that appears
Now click the Base Station menu.....top of the screen....not the Base Station "tab" in the center of the screen
Click Restart

I have a Power PC G4 which is running on OSX 10.5.8, it has the AirPort utility but cannot connect to the internet as my iMac can, I think I might need an AirPort Card? Is that the case or do I need something different to connect to a wireless modem?

Welcome!
Only one variant of the PowerMac G4 could use the faster Airport Extreme Card. The rest used the original Airport card that is pretty slow.
To get fast wireless without buying more than one thing, consider this:
http://eshop.macsales.com/item/Edimax/EW7722IN/
It goes in an available PCI slot
There are USB solutions also. However, all PowerMac G4 towers had only slower USB 1.1 ports, so any USB wireless adaptor can only run at about wireless 'B" speeds (slow) unless you also install a PCI USB 2.0 adaptor card. Doing that would allow a USB wireless adaptor to run at its maximum rated speed. These items working together would accomplish that:
USB wireless "dongle:"
Newer Technology MAXPower 802.11n/g/b USB Adapter + Plug and play direct or with extension cradle
USB PCI adaptor:
http://eshop.macsales.com/Search/Search.cfm?Ntk=Primary&Ns=P_Popularity%7c1&Ne=5 000&N=7069&Ntt=USB+PCI
Each approach has its advantages. The PCI wireless card is a one-piece solution that takes up no desk space. The USB2 card+USB2 Dongle gives you more fast ports for transferring date from other external USB devices (primarily cameras and external hard drives) at hugely faster rates than can the original ports. I have a USB 2 PCI card in my G4 tower strictly for transferring images from my digital SLR camera in a timely manner.

If not this:
iOS: Wi-Fi or Bluetooth settings grayed out or dim
One user reported that placing the iPod in the freezer fixed the problem.
Also heating sometimes works. See:
Why can't I select my wifi settings?
A trick that works frequently with iPhones:
Settings > AirPlane Mode ON, Do Not Disturb ON
Power down and wait 5-10 minutes
Power up
Settings > AirPlane Mode OFF, Do Not Disturb OFF
If not successful, an appointment at the Genius Bar of an Apple store is usually in order.

Then:
Does the iOS device connect to other networks? See other networks? If yes that tends to indicate a problem with your network.
Does the iOS device see the network?
Any error messages?
Do other devices now connect?
Did the iOS device connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on your router

Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.
Some Wi-Fi losses may stem from a problematic interaction between Wi-Fi and cellular data connections. Numerous users have found that turning off Cellular Data in Settings gets their Wi-Fi working again.
You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.

My PC can connect to the airport extreme but with encryption it cannot connect to the internet my iMac has no issues, any help.

My PC can connect to the new airport extreme I just purchased but with encryption it cannot connect to the internet my iMac has no issues. If I open the airport exteme up and provide no security everything is fine which leads me to believe it is something with the encryption between the two devices. Not sure what step I'm missing here this shouldn't be this difficult.

Sorry, I should have been more clear. I am asking if the DNS IP addresses, not the IP addresses assigned by the DHCP service, are the same. DNS is like the Internet's version of the Yellow Pages. Your ISP typically will provide them to you or you can elect to use those provided by another source, like OpenDNS.
DNS is the service that translates a website's URL to its actual IP address so that you can access it. I am just trying to rule out that the PC is not configured properly with the correct DNS IP information.
The other thing to check is if the PC is configured to use a Proxy service. By default, it would not be.
Finally, what is the make & model of the PC. More importantly, if the PC is using either a PCI or USB wireless adapter, what is its make & model?

Apple TV connects to the network but cannot connect to the internet.

Apple TV connects to the network but cannot connect to the internet. Works on other Apple TV's we have just not this new one. Defective??? Thank you!

This might help:
Apple TV (2nd gen.) saw my wireless network but did not accept my password (gave a network error message). It fixed instantly doing this:
Made a note of the Apple TV's MAC address. Get it by pressing Menu on the remote, then Settings > General > About. It's called "WiFi address."
Use your browser on a network connected computer to go to your router settings (usually 192.168.1.1).
Under "Wireless > Wireless MAC Filter" (or something similar) do these steps:
Enable Wireless MAC filter
Enable "Permit PCs listed below to access the wireless network"
Enter the Apple TV's MAC address
Click "Save Setting"
When I did this the network connection immediately started working.
Note: These instructions are based on a Cisco Wireless-N Broadband, model WRT160Nv2, firmware v2.0.02.
