MacBook Error Joining Open Network

A friend bought the new MacBook Core 2 Duo last week. He has been able to access the internet over Airport everywhere he's taken it, but not at home.
At home he has a 2Wire Homeportal with ATT/SBC Yahoo DSL. WEP was originally on, but after numerous attempts to get it to work, we turned the encryption off.
After that, he got online okay for awhile, but after he used another network, his home network still showed up in the Airport menu, but when he clicks on it, it gives him an error joining message.
I've searched through the forums and am mostly seeing problems with WEP, but that's off now... is there anything we can try? (We've reset the modem, the computer, moved some airport preference files, changed some airport settings in the Network control panel).
He's brand new to the Mac and doesn't understand why his old Windows computer has no problem using the network but his new MacBook can't.

Try the following:
Delete Preferred Network(s)
- System Preferences > Network > AirPort > Configure
- In the "By default, join:" pull-down menu, select "Preferred networks"
- Delete the network(s) you regularly use from the list
Delete AirPort Keychain Entries
- Launch the "Keychain Access" application located in Applications/Utilties.
- Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
- Restart, or log out then back in.
Add Preferred Network(s)
- System Preferences > Network > AirPort > Configure
- In the "By default, join:" pull-down menu, select "Preferred networks"
- Add the preferred network(s) using the "+" button.
- Restart or log out then back in.

There was an error joining the network usr5450

Hello,
my girlfriend today bought her first mac. An iMac 20" C2D.
She was uncertain about it because she's a long time windows user but in the end she decided to switch to osx, oh happy day.
At first boot there was immediately a problem. The iMac could see the wireless network (usr5450 access point) but when it tries connecting to it after 20 secs it gives this error message: "There was an error joining the network usr5450".
So we decided to skip the network setup it during first boot and to do it later inside osx with more options.
NO WAY.
I'm clueless.
The network is NOT protected by wep or wpa (her sister's new out of the box vista/vaio connected immediately...oh, the horror!) and I was able to connect with my macbook pro automatically.
Every computer in her house connect wirelessly without problems execpt her new iMac.
I run an hardware test. Passed without errors.
We installed Osx update combo 10.4.9 and AirPort Extreme Update 2007-002. No change.
The network is like that: modem-dlink switch-us robotics 5450 access point.
Please, she's already regretting buying a mac, any help would be very appreciated.
Thanks

Welcome to Discussions, Riell!
Check to see if there is a firmware update available for the router.
The "there was an error" message you saw usually indicates something in the combination of the password and security method selected was not entered accurately or could not be accepted for some reason.
First, turn on AirPort using its menu bar icon.
Then open the Network panel of System Preferences. Click the "Assist me..." button at the bottom and click the blue "Assistant..." button in the drop-down box. This will open the Network Setup Assistant. Click the "Continue" button, then target "I use AirPort" and continue on to setup this new "location" within your iMac's Network perferences. Does this work for you? If not, what message do you get, or where do you run into a roadblock?

There was an error joining the network..... help please

I got a mayday call from a friend with an iBook G4 and wonder if anyone here can help me help him solve this problem. He purchased and set up a Netgear wireless router at home about a year ago and up until a few days ago was able to connect fine wirelessly both at work and at home.
For the past few days, when he attempts to connect to his wireless network at home he receives the message "There was an error joining the network X" We checked the settings and Airport is on and active and his network's name shows up in the list of choices, but any time he connects he is receiving the error message.
He uses an access list so only he and his wife's computers can connect and deleted his iBook's MAC address, re-added it, restarted and still is receiving the error message.
He doesn't use any type of WEP or security, just the access list. Does anyone have any idea why this would just start happening? His other laptop (an iBook clamshell running OS9) is working just fine.
He's running 10.3.9 and is fully updated Thanks.

One possibility is that a neighbor or two has recently gone wireless recently. WiFi has had a huge surge of popularity just the past year. People tend to leave their base stations set to transmit on channel 6 as a default, which can result in interference. Try a different channel, like 1 or 11.

New macbook - "Error joining the Airport Network"

Hey,
Just bought a new macbook which comes with an Airport Extreme card. This has worked perfectly with my home router (Belkin Mimo) and my work router (unknown) as well as in various train stations and public places. However I'm currently staying at my parents house and I can't connect to their router (3Com Office Connect ADSL Wireless 11g Firewall Router). Originally I thought this was an encryption issue - my parents use a WEP password rather than more sophisticated encryption. However even after making it an open network I still get this familiar error message. I was originally able to log onto a neighbouring "Apple Network" which made me think it was just down to this particular router however I can now longer connect to this. Is Airport Extreme compatible with all networks or only the newest? Are there Mac/PC issues here? Or do you think I need to get my macbook to Apple to see if the Extreme card is faulty? I can still use this router via ethernet. I'm up to date on updates and tried most of the tricks suggested in previous threads regarding this error message.

Very useful answer Duane, Thanks a lot, a real sport that you are, you really provided us a lot of help with your answer
On-topic:
I am having the same problem as you guys have (using a macbook pro intel-based machine) and the odd thing is in my case i got this working for some time but now it's not willing to connect whatever I do.
Here's the story:
Immediately after I've bought the mac I used it on an open wi-fi network and it worked. When I got back home I tried to do connect to my private wi-fi router which had wep encription but the airport didn't want to connect it just stayed stone-dead, didn't even want to accept my wep password. I also have a PC& a Dell laptop at home which went flawlessly with my wi-fi network so I thought it might be the OS X fault.
So i installed bootcamp and windows XP Pro SP2 but i reached the same thing: airport doesn't want to connect to wep-encripted wi-fi network.
I then thought - let's try with an open wi-fi network: no result.
I then did the ultimate thing: hard-reset the wi-fi router and I re-configured it as an open wi-fi and finally got the bloody mac airport working. Thought this is it, I would have to live with this but after 2 weeks working time, now that I reach home from work (where I connect my mac on a lan) I can't make the mac's airport connecting to my wi-fi network whatever I do.
It connects though if I boot on the bootcamp windows partition.
Does anyone has any clue how to solve this issue??? I really got to the point of willing to hammer my mac for this. It's really unacceptable for such an expensive machine not to be able to work out a bloody wi-fi device.
Hardware: macbook pro 17" dual-core Intel;
Software: OS X - 10.4.9
Wi-fi&firewall router is a SMC2804 Barricade G wi-fi.

On wake, Error joining my network

Is this a keychain issue or an APE issue? When my Pismo wakes from sleep, my APE signal sometimes goes to 0, but the green light is on. If I manually try to join I get the "error joining network." Normally it joins automatically. (APE v6.2) Have to reboot the APE base station. This happens usually one to three times a day. I might wake it up... ohhhh.... eight times a day.

It's already set up to automatically join the network. The problem is that it occasionally refuses to join on wake. It seems like it might be an issue with the WEP key. I have to reboot the APE to get it to accept any machines with the WEP key. Thanks though.

Mac Pro "error joining wireless network", G5 and iBook OK?

Trying to connect to internet via wireless. The airport recognizes my WPA Personal password but still show "Error joining network", the airport bar is full but cannot connect to internet. The Network Panel says:
"Airport is connected to the network. Airport has a self-assigned IP address and may not be able to connect to the internet"
Here's my setup, every firmware is up-to-date:
Mac Pro 2.66Ghz Dual Core Intel Xeon
OSX 10.4.10
Linksys BEFW11S4 V.4 (firmware 1.52.02)
Airport Extreme card (update to 2007-003)
In Network panel:
Airport- Automatic
TCP/IP- Using DHCP
PPPoE- no click
Appletalk- active
Proxies- manually
In Sharing panel:
Firewall- On
Internet Sharing- Off
I am 100% sure that the router is working because we have a G5 (10.4.1) and a iBook (10.4.9) in the house and there's no problem for both devices, both takes the password and connect to the wireless network no problem.
And one thing, when I go to the setup page of the router (192.168.1.1) and disable the WPA password security, the Mac Pro works perfectly. So whats the problem? It doesn't recognize the WPA?
Mac Pro 2.66Ghz Dual Core Intel Xeon Mac OS X (10.4.10)
Mac Pro 2.66Ghz Dual Core Intel Xeon Mac OS X (10.4.10)

First question: Is there a wireless card installed? It was optional on a 3,1.
Go to System Preferences - Network and see if you have AirPort listed on the left. It also may be turned off which you can fix there.

Error Joining Airport Network

My new Mac will not go online at home - although it will join other networks elsewhere.
There are 3 other Macs online at home and when I set up my new mac I transferred all the settings over so surely they should be the same and therefore able to access the internet?
Have even removed all passwords. Can anyone help?
2.33 GHz Intel Core Duo 2 Mac OS X (10.4.9)

What I do is create a new Network Location called "All Off" in which all network interfaces are disabled. This essentially "reboots" the network connection from the Mac end.
I also prefer a dedicated "WiFi" location to eliminate the possibility of another interface complicating connecting. This location has only the Airport card enabled.
I suggest you set it to the "All Off" location, then powercycle your WiFi router, meaning reboot it. When it is up and connected, turn on your Mac's network WiFi. When mine refuses to connect that always works.

Internet speed issues when macbook pro joins Airport Network

I have an apple tv, two iphones, a PC and a macbook sharing a Airport Extreme internet connection.
The problem is that all devices are working on full internet speed until i connect my macbook pro late 2009.
Normaly i have a download speed at 650kb/s but when the macbook connects to the Airport extreme the internet speed is jumping between 20kb/s and 200kb/s
The unusual thing are the jumps and drops of the speed.
When i shut down the Macbook all other devices are running on normal internet speed and the internet connection is not jumping anymore.
What the **** is going on?

SOLUTION FOUND to MacBook Pro poor Wi-Fi wireless signal.
First, let's talk about the actual problem: too much signal noise. There is a hidden app in OSX called "Wi-Fi Diagnostics" This will tell you everything you need to know why your Wi-Fi is not working!
http://support.apple.com/kb/HT5606
HINT: It is included in 10.7, just look for it.
The solution!
Turn off your wi-fi and run your internet through your home's electrical wires. Power-line adapters are devices that turn a home's electrical wiring into network cables for a computer network.

Office 2011 on Macbook: unable to open network shared files but local copies are fine.

All,
We have 3 users in our environment and only one person is having this issue. Accessing files from a shared location "\\servername\macbk$ gives an error such as:
"This file may be read-only, or you may be trying to access a read-only location. Or, the server the document is stored on may not be responding."
Copying the files locally open correctly.
We have investigated permissions, the share has the correct ACL permission (including everyone full). NTFS permissions on the folder are also set to everyone full. We've reinstalled Office 2011 and have tried Office Preview 2015. We've remapped the drive.
Other applications including text edit, Adobe, etc. open from the share just fine. This seems to be an issue only with OSX and Office, or vice versa.
Any help on this would be appreciated. Thank you.

"Join Open Network" Message

Hello. I have four Macs working wirelessly with an ABS Snow unit. I configured manually and assigned each machine its own IP addy. They all connect without a hitch, except for one machine (which happens to be my main one). It keeps warning me that one of my trusted networks can't be located... you know the rest. I've rechecked all of my settings, and with the exception of the individual IP addys, they're all the same. Ideas?
Thanks.

IBook - error joining the Airport Network

Sorry for the repost but I wasn't sure if me accidently hitting the Correct Answer button would have effected getting a reply
Excuse my ignorance but I've never had a Mac. I recently got this from a friend and I'm having trouble getting it to connect to my WiFi. I've tried everything I could find on google, but nothing has worked. I've made sure my router isn't filtering Mac addresses, I've tried the $ fix, I've removed and changed my security preferences mutiple times, and I'm out of things to try. It works fine when it's connected to the modem directly, but wireless just won't connect. Every time I try I get the error joining the Airport network "xxxxx" but the computer I'm using to type this is connected just fine. Any help would be much appreciated!!
I belive it's a
iBook G3/800 (32 VRAM - Tr)
if not that one then it's a
iBook G3/800 (Early 2003 - Op)
I really know nothing about Macs so I don't know how to tell which one of those it is
Clicking the About This Mac option says...
Processor 800 MHz Power PC G3
Memory 384 MB SDRAM
Machine Model PowerBook4,3
CPU Type PowerPC 750 (2.3)

Right now I have my old ibokk g4 runing OS10.4.11 I'm going to go through the setup on airport using it.I am in system preferences- network. Airport is on and shows in the top menu bar of the desktop.Under show in nework preferences click on network status and then airport. Go to options open and check automaticly join open networks. Click ok. Go to proxies and click. Make sure use passive ftp mode is checked. Go back up and click on the airport bar. Under by default join-click prefered network. You should now have a window showing all networks available.Click on the one that represents your router and apply. If you network is password protected you will need to inter the password. If this does not work use the assit me option . You can run diagnostics to see if it picks up your network or you can run the assistant. It will ask you to name the network. then continue and check on airport then you will get abox that should show your router and you'll need the password for it. And thenclick apply. You can also get help in network by clicking the little ?

Error joining network - but other computers have no problem

I've been frustrated by one of three computers in my house having an issue joining my wireless access by Airport (via Westell VersaLink issued by dsl provider) .
My MacBook Pro won't connect to the network, telling me, after I enter the WEP password: << There was an error joining the network "X". >>
The other two computers I use at home, my wife's PC laptop and an old iMac, connect flawlessly with same password. The MacBook had connected fine previously. One day (6 months ago?) it just started with the issue and hasn't connected since.
The MacBook travels with me a lot and has no similar connectivity issues in other locations.
After I enter the correct password, it takes about ten seconds to report the error. If I enter the incorrect password, it tells me virtually instantly the same message as above.

Error joining network

my airport express is working fine with my desktop, but trying to connect to the wireless network is unreliable on my macbook. often i will unexpectedly lose connection and when i go to rejoin a message pops up and says "there was an error joining the network." after a good 5-10 minutes of trying to reconnect it will work. its not just my laptop. the same problems occur on my macbook pro. can anyone help me out?

This has been happening to me also except I get a "connection timeout" error. I have to physically turn off my router, wait a few seconds or so then turn it back on. After I do that, My macbook is able to find the router and make the connection.
I have not been able to figure out why this is happening. I should not have to turn the router on and off to get a connection.
Anyone else experiencing this problem?

Prevent OS X/AirPort from SEEING open networks...

Hello! Say you have a MacBook with AE. It can access not only your own encrypted home wireless network, but also many open wireless networks in the neighborhood.
I know how to make the MacBook automatically join preferred networks, but I want something different. I want to keep the MacBook from even SEEING or DETECTING anything other than my own preferred network.
Does anyone have a solution? Thanks!

thanks for the response! yeah, i agree with you - but i think i've found a way to achieve a similar result.
if you have an admin account and a regular account, you can require the regular user to enter a username and password to get onto any non-preferred networks. it's not quite what i had in mind, but it will work.

I have a new Macbook Pro. It won't join the wireless networks that my old Macbook Pro joined; only some of them (I'm talking open networks). What can I do, please?

I have a new Macbook Pro. It can see, but won't join the open wireless networks that my existing Macbook Pro joins. What can I do, please?
