Cannot connect to the internet - No IP Address

I have seen variations of this problem but nothing that has helped me. I have a Linksys WRT54G Router in my office and connect through a ethernet cable to my Dell computer. My wife has a Dell in her craft room with a USB Adapter that receives the signal with no problem. Her Mac G5 is the problem. Up until last week her built-in Airport Extreme card picked up the signal with no problem. I am using WPA Personal for security. Four days ago she started getting no access to the internet with the "no IP address" response. I have tried everything I have read in these forums that best describes my problem with no results. I would greatly appreciate any help.
My configuration is -- cable modem -- linksys WRT54G router -- airport extreme built-in card. The G5 utility shows airport is connected to the linksys network and that the signal is strong, but no actual connection.
Thinking the linksys was the problem, I went to Best Buy yesterday and bought a Netgear router that said it was Mac compatible, but that didn't help either, so I returned it.
Thanks for looking!!

You have to power-cycle your modem to flash that information down to the TC. Who is your ISP btw?

AirPort does not have an IP address and cannot connect to the Internet.

Wi Fi problems
I have recently changed from a old netgear router to using a vigor 120 modem with airport extreme
Internet connection is established but my airport express reports "AirPort does not have an IP address and cannot connect to the Internet." although status is ON and the correct wifi address appears.
My iPhone also identifies the correct network but cannot connect
Any suggestions?

I don't have any phones, so not aware of the options, but on a Mac to fix this problem it'd likely be...
Instead of joining it from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed. Before I went through network diagnostics and all of that stuff in system preferences, and then I tried the "Join Other Network" method, and now it works like a dream.
https://discussions.apple.com/message/17028445#17028445
Or...
Go to System Preferences
Click Network
Highlight AirPort and click Configure...
Choose “By default, join: Preferred networks”
Select your access point and Remove your access point with the minus button.
Launch your keychain access in Utilities and delete your access point keychain entry.
Reboot

HT4628 My Mac Air OSX10.8.5 won't connect to the internet as it says it has a self assigned IP address and thus cannot connect to the internet. I can only connect to a network by manually typing in the configuration specs. Please help.

My mac air OSX10.8.5 won't connect to the internet. It says it has a 'self assigned IP address and therefore cannot connect to the internet'. Network diagnostics is unable to the solve the problem. It happened suddenly for no reason and now I cannot connect except by typing in the configuration settings manually. Please help me!

Use the Airport Utility or log into your wireless device via http and ensure the DHCP/NAT service is enabled. If accessing via HTTP, you will need to manually set an ip within your local subnet (eg: 192.168.0.x).

I cannot connect to the internet after switching providers. I've changed the email address associated with the new account but am sure there is something else I need to change. Can anyone help me?

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.

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. :)

Some programms cannot connect to the internet

Hi!
I have recently bought a new laptop with windows 8,1. Some of the programms that i mainly download from the internet and not from the store say that cannot connect to the internet. But i have internet... and all the other programms works correctly. I tried
to switch off windows firewall and windows defender but the problem is the same. So what can i do about that?

Some of the programms that i mainly download from the internet and not from the store say that
cannot connect to the internet.
Often that is just a misleading interpretation of "cannot do a DNS lookup fast enough to suit the program that wants one done" and further that the network topology is probably such that the program thinks it is on a LAN and therefore expecting
LAN level response time (e.g. you have it connected to a router with a local address for your DNS server.)
A workaround for such a scenario is making sure that the dnscache contains the full lookup that the program wants. E.g. you can use ipconfig /flushdns then ping -n 1 -w 1 <problem hostname> then ipconfig /displaydns to see how much
time you have to use it (e.g. look at the Time To Live values, which are given as seconds before the entry will be removed from the dnscache.)
Good luck

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?

My wifi diagnostic says I am connected, but I cannot connect to the internet (safari), iCloud Mail, or any other sites. Help?

Power cycle (turn off and on) the router. In System Preferences -> Network, under WiFi does it say Self-Assigned IP Address? Click where it says location in the network's pane of WiFi, click edit location, click the plus icon and type 'test' and press done, then press apply on the next window. Click advanced then in the preferred networks tab, make sure your wifi network is at the top of the list, if it's not then drag it to the top, on the TCP/IP tab, click renew DHCP lease, on the DNS tab, click the plus icon at the bottom left, add two new dns servers: 8.8.8.8 and 8.8.4.4, press OK, then press APPLY on the next window. restart the mac and see if it's fixed.

E3200 Cannot Connect To The Internet

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.

HT1595 Apple tv will connect to the network but cannot connect to the Internet

My apple tv is connecting to my network but it says it cannot connect to the Internet. I've already tried restarting everything and I've also connected it to my portable mifi network with same results. Anybody have any ideas?

This is what the MAC address clone looks like:
Should I enable it? If so, should I put something in the MAC Address? What? I was able to connect it thru my MiFi, but not my home network. Until today, it's been connected to my home network for about 8 months with no problem. Haven't used it for a while...not since I got a new router.

HELP!!!!! I Cannot Connect to the Internet!!!!!!

I just connected my WRT54G router to my modem and hard wired my computer to port 1 on the back of the router............I cannot connect to the internet, but can connect to the router using 192.168.1.1. I am on a DSL connection. Any suggestions???? THANKS!!!!

If you were able to access the router's set-up page using the default gateway 192.168.1.1 with the modem already connected to the internet port of the router, it means that the default of the modem does not conflict with that of the router. if you cant go online, check the status tab and check for IP address. If you got values/numbers there, it should get you online. if not, if they are all 0.0.0.0, it means that you were still not able to establish connection with both devices.
try to connect your modem straight to the computer, if you cannot go online (since you have DSL connection), try to remember if your ISP gave you a username and password. Your modem is set to full bridged so in order for the router to work with the modem, set the Internet Connection type to " PPPoE" (you can see this under Set-Up tab).. and try to check if you can have IP address.
Or if there's no user name and password from ISP. configure first the router without connecting the modem. then change the router's IP address. then connect the router and configure. it should work now. just configure the wireless settings later after you are sure that you are online directly with the router.
