Can't connect to router through airport (problem with encryption)

We have a small office network with several computers connected to a wireless router. A while back all the macs using airport suddenly were no longer able to connect to the internet (email still worked fine) while the windows computers on wireless and macs on lan still work fine.
The router is using WPA personal encryption, and when using this the macs can connect to the wireless network no problems, but then they aren't able to use the internet. as i said though email still works without any problems. We spoke to the tech support at our ISP but macs aren't very common in south africa, so they just suggest we change the encryption from WPA to WEP encryption. I tried both 64 bit and 128 bit but every time i get an error saying: There was an error joining airport network. If I turn off encryption though everything works fine and the macs are able to access the internet without any problems. Anybody have any ideas what might be wrong?

I am having the same problems since 3 days ago (Imac core 2 duo 20" 2,16). I think it was after the 10.4.10 upgrade.
I haven't tested if I can connect an open network (without encryption).
I can't connect to internet using the wifi network... sometimes, i can't even locate the SSID's network.
Even using windows xp with bootcamp i can't use the network, so it's really strange. This can only be firmware/hardware... cause XP on my mac was able to connect and now it can't too. I tried with other computers (notebook) and i can connect without problems.
Have you solved this issue ?
Anyone can help?

Can't connect to internet through Airport Express anymore

Suddenly, my PowerBook can't connect to the internet through Airport Express. Monday late afternoon--everything was fine. Put it in sleep, come back a few hours later, can't connect.
Thing is, Airport/wireless is working. Can stream audio to my home stereo.
And the DSL/modem are working. If I connect the machine via ethernet directly, I'm online.
Saw that some other users began having problems with USB/printer connections Monday. Could my problem be related?
What gives?
Any ideas?

Hello mnkyby. Welcome to the Apple Discussions!
It sounds like your AirPort Express Base Station (AX) in not getting a proper IP address from your modem.
Try this ...
o Connect to the AX's wireless network, and then, run the AirPort Admin Utility.
o Go to the Internet tab.
o Note the value for IP address. (Note: Do not list it here on the forum, just note what it is.)
o Is the IP address what you would expect from your ISP or is it something like: 196.254.x.x?
If the latter, try the following ...
Modem/Router Power Recycling - Quick
o Power-off the DSL/Cable modem, AX, & computer(s); Wait at least 5 minutes.
o Power-on the DSL/Cable modem; Wait at least 5 minutes.
o Power-on the AX; Wait at least 5 minutes.
o Power-on the computer(s)
If this fails to get the modem to "recognize" the Internet router, then try the "Full" version.
Modem/Router Power ReCycling - Full
o Power-off the DSL/Cable modem, AX, & computer(s). (Wait at least 30 minutes. If possible, leave the modem off overnight.)
o Power-on the DSL/Cable modem; Wait at least 15 minutes.
o Power-on the AX; Wait at least 5 minutes.
o Power-on the computer(s)

Can't Connect to Router Using Airport Through Mac Mini

Hey guys.
I got a new 13" White MacBook in Jan. of this year (2009) and it hasn't given me any trouble, until now.
I've been able to connect to any wireless network before, both through modems and computer-to-computer.
However, my new router is giving me some trouble. It's a Tenda brand router connected via Ethernet cable to a new MacMini. The internet on the MacMini is working fine, but I can't seem to find the wireless network the modem should be giving off on my MacBook. As I said earlier, I've never had any problems with my airport before.
I have all the information needed to connect to the modem (IP, Subnet Mask, Router , and DNS Server) but I'm not sure where/how I'm supposed to enter them.
Can someone help?

Well, i fixed it! Thanks to other questions in the Mac Forums, i learned that if i turned on the Internet Sharing in my System Preferences i could use the Mac Mini as a sort of 'host' computer. For any having the same or similar problems, here's the thread:

Can't connect to internet through airport extreme but have full signal

I've seen a lot of posts but I still can't connect wirelessly via airport extreme.
Using a Powerbook running 10.6.4, I have updated the airport extreme's firmware and have a full signal strength, but I can't connect to the internet.
I get an error message that it can't find the server.
I can get online if I connect the internet cable directly to my computer.
so..
Airport is working
Internet is working
Wireless is not working
suggestions?

That's not possible. Do you mean "MacBook"?
I ... have a full signal strength, but I can't connect to the internet.
First try resetting your connection settings using the steps listed in this message:
http://discussions.apple.com/thread.jspa?messageID=10695921&start=1
They're not guaranteed to solve the problem, but they'll only take a minute or so to try.
If that doesn't help, connect to your wireless network, then open the Network panel of System Preferences. Select the AirPort connection item, click on the "Advanced" button, then on the "TCP/IP" tab. What do you see for the three values below "Configure IPv4"? Now click on the "DNS" tab. What do you see for "DNS Servers"?
Finally, type this URL in the address bar of your browser:
http://74.125.157.99/
and press "return". Does that take you to Google? If so, there's something wrong with the way your computer or router is handling DNS lookups.

Mac connected but PC can't connect to internet through Airport Extreme

When I was using a dial-up connection everything worked fine on both computers but since I changed to a PPPoE / Ethernet connection my PC using Windows XP can't connect to the internet although is connected to the Airport with excellent signal.
In System Preferences>Network I have Connect using PPPoE option checked so I can't see my airport in the Airport Admin Utility. Apple Talk is Inactive.
In System Preferences>Sharing>Internet: Internet sharing is Off and there's a text that it can't be turned on "because there are no ports available over which to share your connection"

I understand, but for some reason, that I'm trying to
figure out, when I uncheck the PPPoE option on my
computer and my base station appears in the Admin
utility, I loose my internet connection on the
macintosh although the Network Status says that I'm
connected to the internet via Airport...
You will need to configure the Airport to connect via PPPoE.

Can't connect to internet through Airport network

Previously - worked
Internet: DSL
Network: via Airport Extreme
Computers: 3 (G4 Tower, PowerBook G4, Xbox360)
Setup: I ran the ethernet cable out of the modem into the Aiport Extreme. Then I ran another ethernet cable into a router which then split the signal into two lines -- one going to the tower and one going to the Xbox. The laptop connected wirelessly. This worked using DHCP assigning multiple IP addresses to all on the network and indeed the two computers surfed the net with ease and I had no problems connecting or staying on Xbox Live.
Currently - doesn't work
Internet: Cable (Charter)
Network: same
Computers: same
Problem: I recently switched from DSL to Cable internet for faster speed. Here is what i found: When i connect the ethernet cable directly into the tower from the modem i can access the internet. If i connect the ethernet cable directly into the PowerBook G4 i get nothing. If i try to connect the ethernet cable to the Airport from the modem i get nothing as well. At first all i thought i had to do was change the account settings from that of the DSL to that of the Cable internet -- only there are no account settings for the Cable internet. I literally just plugged in the cable and was ready to go. I have tried resetting my airport to get rid of my previous [DSL] settings and redoing the Airport Setup Assistant to no avail.
G4 Tower, PowerBook G4 Mac OS X (10.3.9)

ok so i unplugged my modem for a few minutes and then plugged the ethernet into the airport and turned the modem back on. now i can get internet on both my laptop and my tower. that works, thanks!
an odd aside tho is that before, when i was connecting through PPPoE, the laptop would automatically connect to my network (regardless of how many networks the airport card was picking up). now that i have the airport set to just connect via ethernet i have to manually log onto my network every time. is there a setting i'm forgetting about that enables automatic log in or is this just the case with connecting via ethernet?
here is the next problem, though. i bought a wireless adapter for my 360 and it cannot detect my network. it detects two other different networks that are in my complex but not mine. i have no idea if this is an airport issue or a 360 issue as powerbooks just automatically detect an airport base station. i have tried testing it in the same room as the airport with no luck. the only way i have connected to Xbox Live so far was to hard line an ethernet cable to the 360, shut the modem off, turn it back on and connect that way. if anyone knows anything about the 360 or has had similar problems trying to get their 360 up and running wirelessly through an airport please let me know

20" imac can't connect to router through wireless..

I have a 20" imac.. and i am having trouble trying to establish an internet connection..
i've come home, turned on the mac and there is no network connection. instead there is an error / alert message - no internet connection.
I connect to the internet using airport on the mac, connected to my wireless N network.. this has been working great for sometime now. The odd part is that the mac still plays itunes through to the airport express device.

Just to add.. if i go in to the network preferences and set the TCP/IP address and DNS manually then i get a connection.
Is this something that has been messed up by 10.6.5 ?

Can't connect to internet via AirPort Extreme with Laptop running Vista

I've seen a lot of posts on this topic, and maybe I'm just out of luck, but anyway...
My PC running XP can connect to the internet through the AirPort Extreme, but laptop will not. I load the AirPort Utility on the laptop. Should I be able to see the base when I run the Utility? It does not see it. I can see the wireless network with excellent strength, but all I can do.
If I can't get this to work, I'm going to just return it and to back to the wireless router. I was enticed by the ability to connect the printer and external hard drive to the base. I would like to get rid of the PC and just use my laptop for everything.

Looking over your original post again, I think I might have misunderstood you the first time. If I understand you correctly, your Vista laptop can see the wireless network and connect to it (so you have access to the Internet), but you cannot see the Airport Extreme Base Station when using Airport Utility.
If your Internet connectivity is not an issue and it's just that you can't see the base station in Airport Utility to configure it, try using an ethernet cable to connect your Vista laptop to one of the LAN ports and see if the base station shows up in Airport Utility then.

Can't Connect to Router Manager

I want to review the Router Statistics but can't get connected.
I have typed in the address,
http://192.168.1.1/
Also tried via the Router Icon &
http://voyager220v.home/
but get message "Can't Connect to Router"
All other web sites are easy to get into.
Any idea of why this problem is occurring?
Solved!
Go to Solution.

Have you tried rebooting the Voyager or resetting it to default by pressing the recessed reset button.
Are all the lights on at the front, and the correct brightness?
Failure of the Voyager 220V power supply was fairly common, but any 12V regulated power unit will work, if it has failed.
The Voyager range of modems were some of the best, I still have quite a few as standby routers and extra wireless points.

EA6900 Can't connect to Router error message from Linksys Smart Wifi

Hello Everyone, I am having an issue where I cannot remotely access my router. I currently have Charter as my ISP and have internet connectivity when at home. I can also access my router through Smart Wifi when on my local connection. When I try to access remotely I get the "Can't connect to the router" error message. I believe that I have enable the correct settings on my router to provide this service. Any thoughts would be greatly appreciated! Thanks in advance. Mike Carlin

Thanks for the reply. ISP: Charter CableModem: Wish I could tell you at this point, but not at home and can't remember specifics. I thought that I did the association. Is this what you are talking about?http://www.linksys.com/us/support-article?articleNum=140177

I have the same problem PLUS I get the "Genius is temporarily unable to show you related music..." whenever I select a song. This occurs even when I log in as Administrator. Updating to 8.0.1 did not fix either problem.
I can access the iTunes Store and download music. Genius had no problems uploading my iTunes Library info, and it can create playlists for selected songs. I believe this rules out communications and authorization problems. I have a G4 Mac Mini, a G5 PowerPC, and an Intel iMac with the same problem, so it's unlikely to be a Mac hardware issue. A firewall problem was unlikely (since I can access the iTunes Store), but I tested this with the firewall off. Both problems still remained. Updating Genius, turning Genius off and then on again, reinstalling iTunes 8, updating to 10.5.5, etc. did not work.
The only unusual factor is that I have HughesNet satellite 'broadband.' I cannot see how that would matter, but perhaps the individual song iTunes Store and Genius features don't get along with something in my HughesNet 'modem.' Any ideas from other users?

Can't connect to router on different network ssh or http

Hello,
I set up my router with one interface on my trusted network. I set it up on this network temporarily just for seting it up using interface 0/0. I then configured the other IP on my to-be DMZ giving interface 0/1 a IP address. (I don't have my public IP address, but when I get it 0/0 will be the internet facing port). I plug in 0/1 into my DMZ and left 0/0 plugged into my trusted network. (I am using a Firebox between the DMZ and trusted network).
I can ping both my 0/1 and 0/0 interfaces, I can conncet via http and ssh to my 0/0 IP, but I can not connect to my 0/1 IP with http (times out) or ssh (nothing on screen).
Can any one help me out with connecting for management to my other interface on my to-be DMZ subnet?
Thanks,
Ken
