Problem with Airport - will connect to a WEP 40/128bit but not a FREE wifi

Hopefully someone who reads this will be able to help.
I connected my iBook to a wifi connection that required a 40/128bit Hex security connection last week, and have since left that connection (although I'm using it now just to try and fix the problem).
Today I went to a cafe with a free wifi connection available, and although my Airport connected to the connection available, it wouldn't allow me to actually CONNECT to the internet in any way - no email, no safari.
I have a feeling I've tripped a setting somewhere for the last connection that I used and now I can't turn it back - I feel like I'm missing a step somewhere.
Any ideas??

Hi.
Moving from one Internet connection to another often leads to problems later. It is not just with WiFi. I have had trouble just switching from wireless to ethernet and back to wireless on the same router.
The usual way to clear up the problem is to delete all your network preferences so that that iBook forgets where it has been. To do this, go to the folder
/Library/Preferences/SystemConfiguration/ and delete the files
com.apple.airport.preferences.plist and NetworkInterfaces.plist. It's safe.
To avoid the problem, set up different locations in your Network Preferences and then always set your location tell your iBook where you are trying to connect from. That way, your iBook will do the right thing for that location; and this will not affect what it does for other locations.

Airport Express 2nd gen will connect to the internet through LAN but not over wifi?

Interesting issue, I can stream Apple TV connected to the LAN port, send Airplay music to my receiver from my iphone, but cannot access the internet over wifi. So it's not Comcast, it has to be the Airport Express, but not ALL of the Airport Express, just the part that sends the internet signal. Is that even possible? I've restarted reset (hard and soft), re-setup, and unplugged everything 100 times, but to no avail. Any ideas?
Thanks!

Ok, thank you.
I know you already tried a number of resets, but please give the following a try to verify that you can get basic Internet access via a wireless connection to the Express from any of your wireless network clients.
I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
If the above steps do not solve the problem, start over with step 1 above, but then perform the next steps between steps 1 & 2. above.
Disconnect the AirPort base station from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Continue with step 2 in the first set of steps.
In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

Airport extreme will connect to some iPhones and iPads, but not all, and will not connect to MacBooks.

Why will the airport extreme not connect internet to macbook or some iPhones? It will connect to all our iPhone 6's and iPads but not to the MacBooks. The macbook says wi-fi has the self assigned ip address of ___,____,____,___ and will not be able to connect to the internet,

Have you done a full restart of the network in correct order?
Shut down everything.. OFF not standby.
Power on in order.
Modem.. wait 2min
Router.. (Extreme??) wait 2min
Macbook.. Only the Macbook.. do restart anything else yet.
Any luck??
No luck reset the Extreme to factory and redo the setup.. this time use all short names, no spaces and pure alphanumeric. Bonus for names <10 characters.
Use passwords with the same rules.. only can be 8-20 characters.. mixed case and numbers.
Try again with the Macbook..
No luck give explicit details of the setup of the whole network.

Problem with airport express connected to a lan with proxy

*in my university exist a lan network with proxy config and port.*
*i searched in the config mode but nothing guide me.*
*If someone know how connect it please answer this topic*
Jf

I think I have it on the right setting - what do I select in the settings?!
To activate ProxySTA, you must set up the Express to join a wireless network and then enable the Allow Ethernet Clients setting; both settings are located in the Wireless tab of AirPort Utility.
It said it was going to take an hour to transfer a 250meg file, so thats definitely still going over wifi.
It still going over wireless is correct. Remember your Mac Pros are connecting to the network over a wireless connection. So, for example, when you send a file from one Mac Pro to the QNAP, that file must first travel to the AEBSn (by wireless), then to the AXn (by wireless), before it makes it to the QNAP by wire.
The other option, which theoretically, should improve the data transfer rate, would be to configure both base stations into an extended network. In this type of network, the AXn would be an extension of the AEBSn's wireless network and its Ethernet port would still be enabled for the Ethernet switch.

Problem with NAT? can get to web server internally but not externally

We are trying to setup our helpdesk software website so external users
can access it. However, we have been unsuccessful. We don't have any
issues accessing it internally from our 10.1.1.X LAN
We have had our ISP setup a public DNS "A" record of
customerservice.amerinet-gpo.com which resolves to 198.88.234.40 and that
appears to be working.
Next we added a NAT to our Firewall to take 198.88.234.40 traffic and put
it to the local IP of 10.1.1.23 which is our local address for the
webserver running the helpdesk software.
We also made sure that BM filters are allowing traffic on ports 80 and
443 to the local IP as well.
We have 4 other webservers (on a separate servers than our helpdesk
software website) that are exposed to the outside in this same manner and
all work fine.
The helpdesk website is on Windows 2003 server SP1 running IIS 6.0. Our
firewall server is NetWare 6 SP5 and BM 3.7 SP3.
I have tried to just telnet to the public IP of 198.88.234.40 on port 80
and it times out. I can't understand why, and have checked my entries on
BM and even deleted and re did them 3 times to make sure I didn't make a
mistake. I even have another web server on that block NAT'd the same way
and it works (198.88.234.36), if you telnet to it on port 80 it goes
right away.
What else can I try? Any insight would be greatly appreciated!
Thanks,
SCOTT

I was really hoping that we had the wrong sub net in BM for the
198.88.234.32 block! When I read your post last night, I thought that's
gotta be it...sadly I checked and it does have it as 255.255.255.240 when
I look in inetcfg under bindings. I even checked our Cisco router as
well to make sure it had the sub net correct since this is the first time
I've tried to use an IP above 198.88.234.36. The router looked fine as
well. Is there anyplace else that this could be wrong, maybe a config
file on BM or something?
Thx,

Problems with AirPort Extreme and connecting to personal ftp

Hi all
I seem to be having a problem with connecting to my personal server outside of my network. When I connect using a static IP within my network(192.168.1.x) I can connect fine using my Mac and PC so I've ruled out improper server settings. I've mapped a port (21) to the same static IP as my server, but I cannot connect. I am prompted with "An FTP Connection to "xxx.xxx.xxx.xxx" could not be opened because the FTP server dropped the connection" I think I've toggled every option in the Airport Utility but nothing seems to work. Has anybody been successful in making this work?
Thanks for any help offered

OK, thanks for the info, which really helps.
Your AirPort Extreme is in Bridge Mode, so the IP addresses that your devices need are being assigned by the Cradelpoint router, not the AirPort Extreme.
Either the Cradlepoint router is not allowing more than 3 devices to connect, or it is your service provider that is limiting the number of devices that can connect....probably because of very limited bandwidth.
I'm not sure whether you want to try to contact support at Cradlepoint or your service provider to try to find out who is actually responsible for the maximum number of connections allowed, since they will likely each blame the other for the problem.
The workaround...if you want to try it, since it bends networking rules a bit....is to configure the AirPort Extreme as a router, not a bridge.
The upside to this is that all of your devices will be able to connect and get a valid IP address.
One downside is that this will introduce what is known as a Double NAT error on the network, but that is rarely serious on a home network, and Apple does provide you with the option to "ignore" the error, so you get a nice green light on the AirPorts.
Another downside may be....depending on the bandwidth that your service provides....that your connection is really slow....as in dial up speed slow....when you have a number of devices all connected to the network simultaneously, since they will all share the available bandwidth is provided.
I never had any problems in the past with wireless connections when I configured the AirPort as the router. But I also was very careful to avoid downloading large files using the Cradlepoint connection since the bandwidth was quite limited.
Not sure how you want to proceed.
We can tell you how to configure the AirPort as the router in this type of setup if you will let us know what operating system you used to configure the AirPorts, but we cannot guarantee that things will work for you if you try it.

Problems with Airport setup after buying Version 7 models, (older ones will not upgrade)

Problems with Airport setup after buying Version 7 models, (older ones will not upgrade)
I re set up my Airport network , having had 4 expresses for years doing a good job. I bought another and an express, but then a time capsule after my external drive died. .Problems with Airport setup after buying Version 7 models, (older ones will not upgrade)
I moved house and have fibre network so 38mb/s - they all look ok on the utility, but its not till I saw the App version that they are not compatible as mac will not upgrade the version 6 ones, leaving me with 2 disjointed networks and 7 appliances, 4 of the old , 3 of the new.
my new house is expansive so i wanted the extended range and airplay in each room.
This is not told to customers, and utility doesnt show any issues.
I do not seem to get any range from either network now, - and I'm quite experienced with airport (6 yrs of setting up & using & extending)
Any advice ?

Problem with Airport express N (2nd gen)

Problem with Airport express N (2nd gen)
Firmware 7.6.4
ISP - 20 Mbps ethernet cable
I have MacBook Air 13 mid 2013 os x 10.9.5, ipad 4 ios 8.0.2, ipad4 ios 7.1.2 , iphone 5 ios 7.1.1
When i try to use speedtest.net from my Macbook i got good results of download speed and incredible upload http://www.speedtest.net/my-result/3801286946 (connection 300 Mbps) , both ipads got terrible speedtest download result and incredible uploadhttp://www.speedtest.net/my-result/i/981631804 (connection 150 Mbps), iphone 5 got bad download and great uploadhttp://www.speedtest.net/my-result/i/981695357.
All these tests were done near airport express with really good signal and 5ghz. I tried to choose different channels, 802.11 mode, guest ssid, 5ghz ssid ...
I think that something is wrong with my new airport express. Can anyone help me to solve this problem?
ps sorry for my bad english

As a last resort, try a factory default reset on the AirPort Express as follows:
Power off the AirPort Express
Wait a minute
Hold in the reset button first, and keep holding it in for another 8-10 seconds while you simultaneously plug the Express back in to power
Release the reset button after the hold period and allow a full minute for the Express to restart to a slow, blinking amber light status
On an iPhone or iPad home screen....
Tap Settings
Tap WiFi
Look for a heading of Setup a New AirPort Base Station. If it appears.....
Tap on AirPort Express just below the heading to start the configuration process on the Express again
If you try several factory default resets, and the AirPort Express does not appear under the heading of Setup a New AirPort Base Station, the Express most likely is defective and will need to be replaced.

Problems with n97 apps connecting to network (Voda...

Problems with n97 apps connecting to network (Vodafone UK – 3G)
Recently a number of my apps which used to connect automatically to the internet (which ever was available – known wi-fi or 3g) have stopped doing this. They now only connect to one known wi-fi.
I’ve tried uninstalling and reinstalling each app, but this hasn’t solved the problem. I’ve checked for software updates and do not believe any have been applied or are available. All apps have been downloaded via Ovi on the phone. I still am able to access the internet by the web browser which was installed on the phone and via google maps (which also still manages GPS position, search, etc).
The apps which I notice causing a problem are:
Sainsbury’s/nectar
Tesco
Map my tracks
Snaptu
Opera Mini
Any one got any ideas???

I have the same problem since i updated my mac to 10.5.6.
Each time I have to do a diagnostic and retype the WEP password to have the internet connection.

Both xp and windows 7 have video problems with my VGA connection using TV

both xp and windows 7 have video problems with my VGA connection using TV as my monitor when it gets to starting up windows no matter what version it will not I have let my mac on all night and still says starting windows or the windows 7 logo and nothing else will happen also when I use a 3rd patty software like peraills or other it works like a charm how to fix it?

To map the drive on your computer click on Start - RUN - type "\\192.168.1.1" and click ok... When prompted for Username and Password type "admin" and click ok... Now you will be able to see the folder which you have shared on your router, right click on it and select "Map network drive" and click on finish.
Now it will map the drive on your computer and you should be able to transfer the file from your computer to the USB drive.

Some progess I see. To be honest, i would not waste your time with trying to connect using wireless.
You are likely to get poor connections and dropping out.
If its working using a cable, then there is no need to bother with giving me the network settings, bu see how it goes, because sometimes giving the TV a static IP address can give better results.
There is an example of a couple of powerline adapters on the diagram below. Just ignore the network switch unless you want to connect other devices which are near to the TV.

Has Apple fixed the problem with 4G cellular connection?

Has Apple fixed the problem with 4G cellular connection on the iPad 3?

Cellular connection problem was for US connection in Houston, Texas. Have an iPad 2 which functions perfectely on Wi-Fi or 3G. Bought an iPad 3 strictly to get the increased speed from the 4G LTE connection. Purchased on with the AT &T cellular. Wi-Fi functions fine, but 4G LTE connection is terrible when it connects at all. Went to AT&T and they said no problems with service in my area, but never get over 2 bars and most times, Web pages load very slow or will hang and not load at all. Went to the Apple store and they said it was AT&T network problem and went to AT&T and they said no problems with their service. Went to the Apple communities forum here and discovered that many people were having the same problems with the 4G LTE cellular connection on their iPad 3's. Didn't seem to matter if it was AT&T or Verizon. So I decided that I would just return the unit and wait for Apple to fix the problem. Hence my question.
Appreciate very much your time in responding to my question.

My iMac is able to use my wireless internet from my airport extreme, however, no other devices(iphone, ipod) will connect. The network shows up, but the indicator just spins without ever joining.

I have tried resetting my airport extreme, creating a new network, etc nothing seems to work.

I have a feeling you may be stuck in bridge mode there...
Factory reset the Extreme (so we don't second guess later), and re-set up the extreme using iOS5 on your iPhone.
Set up your Wi-Fi network with your iPad, iPhone, iPod touch, or Mac.
