Green light, network recognized, still no internet access
Hi all,
After a day of tinkering with my new AEBS 802.11n, I finally got the network up and running, after reinstalling the Airport Utility software and configuring the AEBS settings manually. Yay. But still, I can't get on line. There the AEBS sits, with its glowing green light taunting me, and my MacBook tells me I'm connected to my network, yet zip, nada, no internet access. I've tried unplugging and recycling the modem and the AEBS, separately and together, to no avail.
Does anyone have any advice?
Thanks! Kate
hi kate - oh, i had similar experiences (maybe have a look at http://discussions.apple.com/thread.jspa?threadID=1087373&tstart=0). so for me it looks like a tcp/ip address missmatch. do maybe the following:
check the modem/routers ip adress on the private side (not the public address on the dsl side). some hints to get this address if not available from the modem/routers manufacturer:
- connect the modem/router using an ethernet cable (mine is yellow) directly to your computer
- open safari and enter the address 192.168.1.1 (if you have a netopia modem or 192.168.0.1 if you have a netgear modem or the address of your specific modem/router .... ... right, that's the address you should look for )
- if you have found the right address the a message will follow that you should enter the modem/routers userid and password mostly "admin" and "1234"
- you will get the modem/routers menue where you can select somewhere "status" and you can verify the address. and ensure the modem/router is set to "DHCP" and look for both DNS address entries. these addresses you should set in your airport extreme
- disconnect the yellow cable. and a good idea is to fully restart your computer afterthat
but the main stuff from this story is, that you have to get somehow the ip adresse from your modem/router for your private network side. assuming now it's 192.168.0.1. so open airport utility, doubleclick on the airport extreme icon and select the internet icon.
- then set the addressing mode from dhcp to manual
- set the ip adress of the airport to 192.168.0.255 (this address is out of the DHCP-range)
- set the network mask to 255.255.255.0
- set the routers address to 192.168.0.1
- set the dns-entries to the addresses you have found in the modem status
- i m not sure if it's really necessary, but i have also set the ip address range for its distribution to 192.168.0.10 - 200 (the airport extreme should not make address distribution, because the modem/router is doing that ... but anyway)
- reconfigure and restart the airport
- open in the systems menue from your computer (i don't know the english name of the main mac configuration tool ...), open network, go the tcp/ip and renew the DCHP-lease (also your computer must get a new valid ip adress)
- open safari and then you should come to the internet ...
hope this helps

Mac won't update software or access iTunes shop. Message comes up with 'not connected to the net. Check connections' error. I still have internet access. Changed my Apple ID but no result. Repaired permissions and re-installed operating system.
It sounds like you may have multiple problems, but none of them are likely to be caused by malware.
First, the internet-related issues may be related to adware or a network compromise. I tend to lean more towards the latter, based on your description of the problem. See:
http://www.adwaremedic.com/kb/baddns.php
http://www.adwaremedic.com/kb/hackedrouter.php
If investigation shows that this is not a network-specific issue, then it's probably adware. See my Adware Removal Guide for help finding and removing it. Note that you mention AdBlock as if it should have prevented this, but it's important to understand that ad blockers do not protect you against adware in any way. Neither would any kind of anti-virus software, which often doesn't detect adware.
As for the other issues, it sounds like you've got some serious corruption. I would be inclined to say it sounds like a failing drive, except it sounds like you just got it replaced. How did you get all your files back after the new drive was installed?

Network Diagnostics gives green lights, but machine still won't connect
I am using a AE(N) base station and wireless network, and as far as I know, no settings have changed. My mac mini has an IP address can send and receive mail, but neither Firefox nor Safari can load any webpages and apps that try to connect like software update don't recognize a working connection. Network Diagnostics give me green lights all the way through "Server" and multiple other machines still work on the same network. I have removed the network login info from the mac mini and erased the mini's connection access from the base station and started over. Mini has no change, and the other machines are still fine. I tried creating a guest network and connecting to that, but it didn't help. I'm running out of ideas to trouble-shoot the problem. Any advice is appreciated.

In the Network panel of System Preferences, if you click on the "Advanced" button for your AirPort connection, then on the "DNS" tab, what do you see for "DNS Servers"? How does that computer with the same settings for the computers that are working?
What do you mean by the statement that "I have removed the network login info from the mac mini and erased the mini's connection access from the base station"? -
Airport Express Green Light - Can't Get To Internet
Hello.
I'm staying at a friends cottage. Their internet works fine (I can connect via ethernet to the internet). I can get the wireless network to work fine using Airport Express (green light on AX, shows network signal in menu bar).
When I try and connect to the internet via AX it fails.
I am using WPA2 Personal for the password.
Am I missing something simple?
Thanks in advance.
Hello... I tried to find this before I asked, but I couldn't narrow the search enough to find an answer... I'm sorry if this has been asked a lot before.Michael Tutton1 wrote:
I am connected directly from the back of the modem to the ethernet on the AX.
So you're replacing the friends' equipment (if any) with your AX? Some questions:
1) Did you remove power from the modem for several minutes before you connected your AX? Some modems will refuse to connect to a "new" device until they're reset by that process.
2) How is your AX configured? Settings in AirPort Utility of particular interest are AirPort panel, Wireless tab, Wireless Mode and Internet panel, Internet Connection tab, Connection Sharing. -
New to Networking - Verizon Wireless Broadband Internet Access
Hello,
Just setting up my home network with a router and printer server. However, when I went to set it up, it is looking for a cable to connect from the laptop to the router. I use a Verizon Broadband wireless card that I insert into the pcmia slot on the laptopr, therefore, no wires involved.
Will this work with the router or do I need the cable connection for it to work.
Also, in the setup it asks not only for the IP address (which I think I found) but also a subnet, gateway, dns, etc. Any suggestions on where I can find this info.
Or is this all just explained somewhere in an easy guide when using a wireless internet access card.
Thanks in advance for any help.Thanks for the info. Since I live in a rural location, the only options I have are either slow dial up with MSN or the broadband access card in my laptop with Verizon so I guess I will be limited to the internet only on my laptop if I want faster access.
One thing, though, when I open the program for the verizon card (VZaccessmanager), it shows a symbol for linksys as an available network even though I didn't provide the ISP, etc. answers.
The router that I am using is the WRT54GS and and a WPS54G print server.
And, yes, the ISP question was being asked during the final stages of router installation, along with the gateway question, etc. Now that this isn't going to work with the access card, do I need to answer these questions?
Any help will be appreciated. Thanks. -

Am attempting to set up a Wi Fi network with an airport extreme. Get most of the way through the setup (have a dsl modem) but get an error that it cannot connect to the internet. Says I have a problem with a DSN server and asks for what appears to be a series of numbers. I had an old airport express working for some time and never saw this.
Decided to upgrade since the express was not powerful enough to work in the whole house.It is always a good idea when changing out networking hardware to perform a complete power recycle of all of your networking gear.
Please try the following:
Power-down the modem, AirPort Extreme Base Station (AEBS), and computer(s). Leave them powered-off for at least 10-15 minutes.
Power-up the modem; wait at least 10-15 minutes to make sure that is has enough time to initialize.
Power-up (plug into power) the AEBS; wait at least 5-10 minutes or until its status light is a solid green. (Note: The status light may continue to flash amber after this timeframe. This is ok as it may just be letting you know that some additional configuration items need to be taken care of like setting up wireless security.)
Power-up the computer(s).
Computers connected to the AEBS by either wire or wireless should now be able to access the Internet. Please post back your results. -
Loss of Network signals and random internet access resulted in loss of my business
Hello
Iphone 4s is my first apple product, otherwise i am a android phone user, i wanted to give android a break and try apple for a change. Today is my first day with this phone. I am a business man and business calls to me are very important. I am deeply sadened to let apple management and others know that my first experience with apple was a sour one. First I had to cut down my sim to apple phone desired size as a result i am not able to insert the sim into other phones.; Now I am not able to make calls, every time i make a call i get call failed notice and the network bar just vanishes and reappears again. After trying a number of times i am able to make a call. No doubt the phone is costly but the loss of calls to my phone has cost me tremendously and i am very unhappy with your product as i am unable to switch to other phones. I have recieved a number of calls on my land line number, people saying my mobile number is unavailable. trust me, I will never use an apple product again if this problem is not fixed quickly, i will also discourage others not to buy your products.
I am now forced to give my contacts my new mobile number.
Yours sincerely
an angry businessman
Shaurya ChakarvartyFirst, you are not speaking to Apple. This is a user to user forum.
Second, based on your description, this would appear to be entirely a carrier problem. You should be raising the issue with your carrier.
Third, getting your SIM replaced should NOT require that you change your number. If it did, you either have some kind of pre-paid service or the person who took care of you at your carrier is incompetent.
You should be talking to your carrier about these issues. There are widely reported problems of older Micro-SIM cards and cut SIMs not working properly in the iPhone 4S. As the iPhone 4S has been rolled out around the world, the problem seems to be rectified by obtaining a new Micro-Sim from your supported carrier AFTER the 4S is officially released there.
If you are using an unsupported carrier, all bets are off and the ONLY place you can really go for assistance is your carrier.
A list of supported carriers can be found here: http://support.apple.com/kb/ht1937 -
Mac G5 Airport "NO internet Access" but is connected to WRT54G network
I have read thru prior threads and nothing has worked. I have connected to the internet once. I have upgraded the firmware to the wrt54. I have tried both PPPoe and DCHP to connect as well as using the built in ethernet. Why will it connect to the network but have no internet access?
The network status on my G5 says "Airport connected and You have internet access through Airport. But when I try through Safari, the screen comes up "no internet connection". Currently my wrt54 is 192.168.2.1 and I have set the security to allow access to the router. Can someone layout what my mac and router settings should be, If they are working for them? After trying somemany different things, I worry that I am not trying the right sequence of settings anymore. Help!
Many thanks!I have upgraded my router firmware to the latest, at least what is available here at linksys. The airport does retrieve the address from the router, but no go. Should it be set to PPPoe or not? If it isn't. it doesn't look for the host. When its off, the network status says connected to the linksys network, internet access through Airport, but still no Safari. I don't understand, if it is connected to the network, what is preventing it from connecting to the internet, which is available on the router? My DHCP server is enabled, I have changed the address to 192.168.2.1, 50 clients, but there are no DNS static address'. Should I input some DNS Address? My router is connected to a DSL modem and hardwired to a PC through the net connection. This is how I access the router. Whoops gotta get to work...........
Thanks for your help -
Can't get on internet thogh i have a green light
hello, just upgraded to a dual 500MHz mac form a B&W G3 and am having problenms getting on the internet. i have a Netgear WG111 Wireless usb thingy. the software says i have a signal, and the network has a green light, it says i hav internet, but when open firefox or safari it says i am not connected tot he internet. all was easy and fine on the B&W. i'm running 10.4.11, adn i have the driver for 10.4, pretty much all is the same except for the meachign has changed. any thoughts? thanks -j
hi, turns out i was using the wrong location (its a studio setup and we all share a signal). with the correct one chosen, and with the DNS numbers inputted from above, i get a signal, its just kinda slow. i get 45% signal strength, which is probably why. but its works ok, just not for downloading. email is fine. thank for all your help!

I need to set up Profile Manager on a completely closed network that has no Internet access at all. I can sneaker-net files into the network if I need to.
Profile Manager (and Lion Server in general) seems to need outside access to complete setup and I've been unable to find any meaningful answers.
Does anyone any any ideas?
Thanks to allyou could try it without enabling apple push notifications in server
you wont' be able to push out profiles without enabling apple push notification
but users could download them, or you could install manually, e-mail etc -

WRT54GS Blocking Internet Access
Hi,
I have a WRT54GS router that constantly blocks the internet access. Any computer (Mac or PC) is able to access the wireless network, however, no internet signal is passed through the router. I know the internet signal works because you can connect directly to the cabel modem and the internet works fine. When the router is connected to the modem the internet light on the front of the router blinks (as if there were data being transmitted), but still no internet access availabe.
I have tried unplugging and fully restarting both the modem and the router in every order and combination possible with no success. The only way I can solve this problem is to leave both the modem and the router unplugged for 24 hours and then plug them both back in. This problem/blockage only seems to occur when the router has been inactive for 2 or more days (when I leave out of town or something).
Any help is greatly appreciated!
Thanks,
JordanStart with restting your router...
Press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...Now re-configure your router...

I can connect to "linksys" as a wireless network, but get no internet access. Please help! Thank you!The settings that you provided is for the modem so I suppose you can able to go online with modem… Please let me know the IP address that you receiving from the modem… Since the connection that you have is DSL connection and if you are receiving the IP address from the modem under LAN (Local Area Connection) is a Private IP address (192.168.X.X) then follow the steps:
# Connect the modem with the Linksys Router WRT54G on the Internet Port and then connect the Computer on any of the Ethernet Port on the Router (Numbered – 1, 2, 3 and 4)…
# Open up the browser and on the address bar type 192.168.1.1 that will open up the Router setup page…
# Look for the Local IP Address and change it to 192.168.2.1 …
# Click Save Settings...
# Then Click on wireless Tab create the Wireless Network Name SSID and select the channel to 6, 9, and 11… Click Save Settings...
# Then Click on Wireless Security sub tab and select the security mode and provide the password as per the requirement… Click Save Settings...
# Click on Status Tab on the Router Setup page check if Internet IP Address has numbers or values. If the Internet IP Address has numbers, the computer should now be able to access the Internet. If the IP address is all zeroes (0.0.0.0) click "IP Address Release" first then click "IP Address Renew". If the IP address is still all zeroes, enable PPPoE on the router.
To enable PPPoE on the router you should have a username and password provided by the ISP (Internet Service Provider) and follow the steps...
# Under the Setup tab, set the Internet Connection Type to PPPoE…
# Enter the Username and Password that your ISP provided, including the domain in the User Name field if necessary…
# Click Save Settings...
# Then Click on wireless Tab create the Wireless Network Name SSID and select the channel to 6, 9, and 11… Click Save Settings...
# Then Click on Wireless Security sub tab and select the security mode and provide the password as per the requirement… Click Save Settings...
# Click the Status tab then look for Login Status and check if it says Connected. If it’s connected, you should be able to access the Internet.
After doing the following settings then connect the wireless computer the preferred Network… Once it gets connected you will be online wirelessly as well… -
"No internet access" on Guest Wifi
We upgraded our router the other day, we made a backup as well as a txt copy of the config file for copying in various commands to the new router .
We have a Secure wifi for employees and a Guest wifi for visitors. We have a server doing the DHCP(10.27.131.8) for both the secure (10.27.131.0 network) and for the Guest (10.26.131.0 network). The Secure wifi is working as it should be - the Guest however is not. Visitors can connect and get a valid IP address from the 10.26.131.0 network but have no internet access. Everything else has stayed the same - no changes to the AP's.
Again we copied the config from the old to the new with a few minor changes but nothing that should effect the Guest wifi.
I did an ipconfig after connecting to the Guest Wifi and I can get a correct IP address 10.26.131.214, Default GW: 10.26.131.1.
I enclosed the config from my router is anybody could shed some light,
Thanks in advance.

access-list 102 permit ip 10.27.131.0 0.0.0.255 anyHi,
I also apologize for my late answer.
I appears your ACL 101 that filters traffic entering the Fa0/1.20 is not correctly written to allow DHCP requests to be processed by the router. The attempt has been made - but it is not correct. In particular, check out the second entry in the ACL 101:
access-list 101 permit udp any host 10.27.131.8 eq bootps
It allows all DHCP messages that are already targeted to 10.27.131.8, the DHCP server. However, such targeted DHCP messages may be used by clients only after they know who the DHCP server is in the first place. Until then, the requests are targeted to 255.255.255.255 and sourced from 0.0.0.0. Such packets are not allowed by any entry in the ACL 101 and are therefore dropped even before the DHCP Relay Agent can process them. That would explain why your clients actually cannot obtain IP address via DHCP in VLAN 20.
We need to add the following entry immediately before or after the existing second entry in the ACL 101:
access-list 101 permit udp any host 255.255.255.255 eq bootps
You may accomplish this by the following sequence of commands directly pasted into the global configuration:
ip access-list resequence 101 10 10
ip access-list extended 101
15 permit udp any host 255.255.255.255 eq bootps
end
The first line will cause the individual entries of the ACL 101 to be internally numbered, starting with the sequence number 10 and incrementing by 10 for each subsequent entry. The second line enters the ACL 101, treating it as a named ACL, allowing us to use the extended editing features. Finally, the third line starting with the sequence number 15 will cause the entry to be added between the existing first (seq no 10) and second (seq no 20) entry. It must be entered including the sequence number, otherwise the line will be added at the end of the ACL.
Would you mind trying out this modification? The former corrections with the NAT I have described earlier must be applied as well.
Best regards,
Peter
