Lost connection to internet via 'airport' WiFi and 'NETGEAR WNR2000v' base router

After trying to connect 'MacBook Pro SnowLeopard' via Fire Wire '6pin to 9pin' to new 'iMac-LION' there is no possibility anymore to get contact to the internet, even all Network 'airport' configuration and passwords has been still the same. The 'NETGEAR router' configuration and activity was reset and checked successfully many times. Windows XP through 'Internet Explorer' by Ethernet cable via 'NETGEAR router' still works perfect. But 'airport WiFi' of both Mac's are screwed up suddenly completly after working perfect for more than 1/2 year! Need some help to get it working again!

Can't connect to Internet via Airport but CAN via Ethernet

Yeah so I have tried TWO different of my AX's and can not connect to the internet via EITHER even though Network Status says "you are connected to the internet via Airport". But, if I hook the ethernet cable directly to the computer from the modem it connects to the internet fine. What am I missing. Oh yeah, and on one of the AX's the "music" tab does not appear next to the "WDS" tab thus not allowing AirTunes on that AX, any ideas on that too? PLEASE HELP!!

CONNECTED!! After resetting the modem, llike you suggested, I am able to get the wireless network back up and running, BUT...I am still having problems with one base station not showing the "music" tab and thus not letting me stream music to it. When I hit "configure" the tab shows for a quick second then disappears. Any idea?

24" imac 2.4 says connected to internet via airport--but does not

I just got a new 2.4ghz 24" aluminum imac. There are three other macs in my house, all of which connect to our wireless network and are able to browse the internet. This new computer can connect to the network, yet it always has one of two problems: either it says it is connected to the network, but can't access the internet, or it says it is connected to the internet via airport, but when you open your web browser, no such luck. Many times when I open the network preference panel, there is no router number assigned. Sometimes there is. I can connect to other networks in the neighborhood that don't require a password just fine (how I'm writing this). Why can this new machine not connect, when all three of the other macs in the house have no problem?
anyone, please help. this is frustrating.
thanks,
keegan

OK but, like you, my other machines (PowerPC iMac and Power Book) did seem to work OK while the new iMac was playing-up. It was only when I noticed that the Old iMac had not downloaded some podcasts that I started to look at the router. I now remember having a similar problem a few years ago - frequent failure to automatically log-in to the router, occasional failure of manual log-ins and slow/unreliable connection once logged-in. A new router fixed the problem. It's a real pain but there you are. Must remember to keep receipt of current router and kick-up a fuss if it fails within the guarantee period.
Sorry if this doesn't help but I thought it worthwhile posting my experience over the last 2 days.
Have you tried connecting to your router by ethernet?
I'll let you know if the problem returns but all is sweetness and light at present.

Network prefs: "connected to internet via airport"... but can't go online??

I've got steady green lights on my airport express and modem/router; and in Network Preferences it says that I am connected to the internet via Airport (green light here too). BUT, I can't get online with any of my browsers or my mail client. What's going on here? Help appreciated.
Thanks

If you have a Modem Router combined and an Airport Express
The Express must be set up to NOT DISTRIBUTE IP's.
You do not mention what brand Modem or Router or Modem /Router combined. Your network confiquration can very a little depending on what you are using.
If you are using all Apple Airport products the confiquration is pretty straight forward.
If you are using 3rd party products then the set up can be a little different.
From what you say in your post you are using 2 routers, my quess is the Express is set up to distribute IP's and if your other router is set up this way then thats your problem.

Trouble connecting to internet via airport

i can't connect to the internet via airport. Does anyone know what the problem may be?

There are several items that may be behind this issue.
So troubleshooting them by trial and error is most likely
a way to attempt to resolve the cause, especially with
an older OS X and hardware, while trying to connect to
a newer base station and different newer frequency...
•Wi-Fi: How to troubleshoot Wi-Fi connectivity
http://support.apple.com/kb/HT4628
The above covers several areas of settings and ideas.
If the computer has been online, and now does not work
wirelessly, that may be a matter of an accidental change
in settings; or something turned off that used to be on.
A general overview, w/ examples of settings similar to the above, for 10.3.9/10.4.11 appears here: http://www.tr.txstate.edu/get-connected/computerservices/wireless/encrypted/maco sx-wpa2.html
Is you computer running OS X 10.3.9 Panther? If so,
your built-in AirPort card may be an 802.11b version
and the security protocol would not work with a newer
or modern wi-fi base station (WEP, WPA) unless those
settings were changed. You can turn off security if the
computer is too old to be able to connect with the old
settings for that protocol. Also, a later wireless base
station may not see an old wi-fi card using 802.11/b.
So it is a matter of knowing what you have on either side
of the connection issue; the base station and the wi-fi
card have to use the same frequency and security. Or
there are work-arounds to attempt to correct this matter.
Hopefully you can connect and use the wi-fi internet.
Good luck & happy computing!

Both iMac and powerbook can't connect to internet via Airport.

I have an iMac that is directly wired to an airport base station and a G4 powerbook that connects via a card. Neither can connect to the internet. The iMac is set up as follows:
Cable modem > ethernet cable to WAN port on AEBS > ethernet cable from AEBS to iMac.
The powerbook detects the base station and created its own network as soon as it did, yet still nothing. The first and third lights on the AEBS flash as to show activity and I have unplugged the modem to reset it multiple times.
I am completely confused as to what is going on. Can anyone please help?

If it helps any, I'm in the same boat. I've had an AEBS that has worked well until yesterday. Now, my Powerbook can't connect to the internet via wireless or ethernet (connected directly to the AEBS). My POwerbook CAN talk to my networked HD. To make things worse, my two Tivos (connected to the network via an Airport Express & WDS) CAN connect to the internet.
I'm totally confused. Since I can't connect to the internet when directly plugged into the AEBS, but can connect when I plug directly into the cable modem, I think I'm going to just buy a new AEBS...

Lost connection to internet through airport

My Mac at home is configured to a timecapsule and connected through airport wifi. The Time capsule is connected via cable to modem and out via cable to Internet. Up until today everything is fine. started up and i have lost connection to the internet.
Network Preferences is showing that Airport has a self asssigned IP address and cannot connect to internet. The time capsule lights are showing green, as do the Modem, neither are reporting problems.
I have tried all of the "first Aid configurations" i.e. switch off/on etc, also tried a couple of ideas from forums, nothing works. I can connect the Mac directly to the modem via cable and access the internet.
As an aside, My iphone has also lost connectivity through home wifi.
It would appear from other forums that this is a growing problem, however not much in the way of resolution. Any Ideas????

Connecting to home internet via airport - always need to restart the router

I set my home PC as the main station to connect to my ISP. With a wireless router (linksys Wireless-B), I used to share the internet connection to other wireless devices, for instanace, my palm and ibook, my sister's notebook PC and Pocket PC. once, I took my ibook to an internet cafe, which gives free wireless connection facilities. My ibook obviously scanned the wireless network, and was connected (as I noted from the Summary of the "internet Connection". but, when I activate Safar, it said that it could bring me to any website because my computer is not connected to internet. it's very strange, as the Internet Connection said it's connected to the wireless network. The Safari page suggests me to run "network diagnosis". i follow the instruction, and it says I should restart the router and then it would work. I didn't succeed. A while later, it connected. I thought it was okay.
Then, this problem comes up even when I am using my home's internet connection via the airport. I use DHCP to connect to my home internet connection. though the airport summary page said that it's connected to my router (the IP address is my router's address), again, Safari said my computer is not connected to internet, so it didn't work. I followed the instruction of the Network Diagnosis, it again asked me to restart my router device. I also noted from the Airport Section of the Network Perference that, it says the airport has a self-designated IP addres, so it may not connect to the itnernet. later on, I retarted the router and the modem (without turn on my home PC), the ibook connected to the internet.
i checked the router setting of my home PC. I'm sure that it's open to all wireless user. Strange through, after I update the settings (even though i didn't make any changes, perhaps the action of 'save settings', it's kind of equivalent to the action of restarting it), my ibook's connection works. When my retarted my PC and ibook, the connection problem comes up again.
it's very frustrating. Does it mean that I need to restart my router everytime? What about if I want to connect to wireless hotspot outside?
Please please help

Your problem description is complicated, making it hard to figure out what exactly is wrong. Unfortunately, WiFi does this quite often.
To avoid this kind of problem, you should set up different Locations in your Network Preferences for different places that you connect up. That is, make one location for your Internet cafe and another for home. Leave the Automatic location alone.
For locations you know you are going to connect by WiFi, go to Network Port Configurations and drag Airport to the top of the list to give it priority.
If you have a location, where you want an ethernet connection or want to use your internal modem only, then drag those options to the top. Get the idea?
MacOS seems to get confused sometimes when you switch back and forth between different connections all the time. This will not happen if you tell MacOS where you are by explicitly setting a location.
To get out of a situation where MacOS thinks you are connected to non-existent ethernet connection, go into
/Library/Preferences/SystemConfiguration
and delete the NetworkInterfaces.plist file.

My MacBookPro only connects to Internet via a WiFi hotspot

New MacBookPro laptop with OS 10.8.4 with Airport turned on connects via WiFi hotspot to internet but will not connect wirelessly to Internet via modem and router connected to cable service. Will also not connect via Ethernet to modem and router to cable service. Desktop does connect. Any suggestions for connecting via Airport to modem and cable from MacBook Pro laptop?

Macbook connectivity to internet via airport extreme is flakey

Hi,
Just bought a brand new airport extreme and I already own a June 2009 Mac book pro w/ snow leopard.
I always run software updater, so the Airport 2009-002 patch/fix is on this system.
I have a strange problem with my connectivity to the internet from my mac via the airport extreme.
Very regularly (and seemingly randomly) the laptops connectivity to the internet will drop out... i.e. websites won't respond, big websites (like google) don't respond to pings or anything. While these internet "drop outs" are happening, i can jump onto my PC (which is connected to the airport extreme via ethernet) and the internet is working fine.
Also, Wifi never drops out through this whole situation. This means that while I can't access the internet, my reception is still FULL and I can SAMBA connect to my PC and with other computers on the network.
It's very strange that purely internet via the Airport Extreme is having these issues.
The Airport is in Bridge mode (which means the ADSL modem/router is the DHCP server). The ADSL modem/router does not have wifi active or anything connected to it (other than the airport).
I've never had any issues with my internet - this is the first. My only real option if this can't get resolved is to return the airport, as this is inhibiting me from working from my laptop.
Anyone else experience similar issues?
Can someone recommend any course of action to work around this issue?
Is there anymore information this forum needs to debug this problem? How can I obtain this info?
I hope someone can help.
Regards,
Vijay

I seem to be in a very similar predicament, however I'm served even worse:
I'm loosing Internet connection over both LAN and WIFI. And the Airport Extreme does not detect the loss of connection even though the logging indicates the internal ntp client (trying to connect to time.euro.apple.com) fails (already on dns resolution).
Currently, I'm dvlp-ing a shell script that checks 4 websites, and if all 4 are unaccessible, I launch an applescript that restarts my airport extreme basestation.
This however does not always seems to solve the problem. Seemingly I would have to reset the modem.
The problem can - according to me - not be provider related, since it does not occur when the TimeMachine is replaced by a SL-installed mac mini (that however cannnot function as router (yet)).
Any hints ? anyone ?
I previously had installed an Airport Extreme 10/100 version, which showed the same behaviour. Since the system was out of warranty, I decided to upgrade to a faster system, including TimeMachine, but unfortunately, the problem is still there.
I'm guessing now it could be related to the router being configured in dhcp (getting its ip address over dhcp), but the server provides a static ip address (never changes),... and maybe here there's something fishy.

Unable to connect to Internet via Airport Express - 'cannot contact server'

I'm unable to connect to the internet via my Airport Express. I'm using OS 10.3.9, and had the same setup with no problems at a previous address, but with a different modem from the same ISP.
My AE is connected - the light is green - and my mac is connected to the network in Internet Connect. But when I open Safari I get an 'unable to contact server' message.
I've tried rebooting everything (modem, AE, Mac), and leaving modem/AE off for several minutes. Also reset the AE, but to no avail.
The connection works fine via Ethernet cable.
Any ideas?

Thanks, I checked out that advice doc (106798), but could not connect to the address (http://17.149.160.49) which is given to test if it's a DNS issue. My ISP says I shouldn't need DNS settings.
The service is PPPoE, and I went into Airport Admin Utility to check if the Airport was configured for this. Under Configure/Internet, I found it was set to 'Ethernet', so changed it to PPPoE. Then when I restarted I got connection status in the bar (and good Airport signal), but status flipped between 'looking for PPPoE host' and 'negotiating PPPoE host', sometimes sticking on one or the other each time I tried rebooting all gear.
Any other ideas?

Can't connect to Internet via Airport

I have a PPPOE ISP account. Before upgrade to Lepoard, just fine. Now I can only connect to internet using cable via my router moderm. I cannot connect my wireless router.
The wireless router will appear to be connected but it said self assigned IP. If I hardcode an IP eg. 192.168.11.2 to it. The Airport status will become connected but still cannot dial into my PPPOE account. An message no PPPOE service will appear. But if I plug in the LAN cable, everything work fine. Why this happen? My wireless router work fine with my Window XP and my Mac (before upgrade to Lepoard) What configuration should I change? I am an idot to networking. I have download all patch and has tried boot to safe mode etc.
Anyone can help?

By power downs do you mean Sleep?
One thing that might work is to set the IP to Static in Network>Configure IPv4>DHCP with Manual Address.

Pc cannot connect to internet via airport

Hi
I have an older Airport Extreme base station (round pyramid style) that is fine with my Mac (MacBook Air, iMac, iPad-2, iPhone 4+) and other wifi devices.
However, we also have various PC laptops (needed for work) that can connect to the Airport base station (PC= green line from pc to base, red line crossed through to internet Windows graphic) but NOT to the web (?)
We have high speed DSL, and a modem plugged directly into the base station.
How can I set Airport up or the PC laptops, so that the PC laptops can have access to the web and everything stays the same for all of my other stuff?
Very behind in my work...

Hi,
I believe you have the problem that I was able to correct last weekend on my son's pc laptop by updating the atheros wireless adapter drivers. Here are two simple options to test if you need to get an updated driver for the pc wireless adapter. The first is to just connect the laptop to the Airport Extreme with a network cable. If that is not an option, enable the guest network with no security on the Airport Extreme and connect the pc laptop to the guest network. If either method works, the wireless security method is the problem and a new driver was the solution.

Powerbook Titanium won't connect to internet via Airport Extreme.

Hi everyone, I just boght an used Airport Extreme (White UFO version) and getting it to work with my MBP took about 5min and then it worked like a charm but my wifes Powerbook titanium is another thing...
It will connect to the router but I can not connect to the internet, the same with my "Scrap/sparepart" Powerbook titanium... it connects to the router but it stops there. My wifes PB has an original first gen. Airport card and my spare PB uses an Sonnet extreme PCI card.
I have tried it with WEP, WAP and without security no differens what so ever.
Im starting to lose my mind here running out of ideas...
And my wife is getting more and more crumpy since she cant check mail or surf on her computer.
Help please.
/Dan

It sounds like the problem with the PowerBooks is that both have the incorrect DNS settings for your ISP.
On the MacBook Pro go to System Preferences > Network, and then, note the DNS Server IP address(es) value(s). Then go to each of the PowerBooks and do the same. They should be the same. If not, change the DNS IP addresses to match those on the MacBook Pro.

Only one of three computers can connect to Internet via Airport

My partner made a change in airport settings when a problem with the router came up and I only partially have it fixed. We have three different computers that have all been accessing the Internet via an 1st generation Airport extreme. The Airport is connected via ethernet to the cable router. One computer, the one that was used to set up the Airport originally, can connect to the Internet just fine. The other two laptops can "see" the Airport network, but cannot get an Internet connection. Do I need to reset the Airport and start over?
Thanks for your thoughts.

Your partner likely changed the AirPort to Bridge Mode based on the information in your post.
Check the following setting on the AirPort Extreme using AirPort Utility - Manual Setup
Click the Internet icon
Click the Internet Connection tab
Connection Sharing = Share a public IP address
Update to save settings and allow 25-30 seconds for the AirPort to restart.
Then restart the entire network again.
