MacBook won't connect to wireless connection.

Have you tried restarting the MacBook?

Also try reseting the router.

My macbook use to drive me nuts, it would disconnect for no reason and take 60 seconds to connect if i was lucky....my MBP does not do that.......never found out way

This isn't a hardware issues. It's a known software issue.

The best thing to do with a Mac, is if you have a working Airport driver, never update it. Airport updates, often times, cause more problems than they fix.

Okay, this might help! It worked for me. Hope it works for you too.

First you need to check your router settings. Is the Wireless Security Mode set to WEP (Wire Equivalence Protection)? If so, this is what you can do.

- Open Networking > Choose to connect using the AirPort
- Choose the wireless network you want to enter
- For the password, use the WEP Key from your router wireless settings page. Now here is the trick. When entering a WEP key on the mac, you need to add and extra '$' sign before your password. That's it. So if your password is - 9876543200, enter $9876543200.

It worked for me. After hours and hours of trying and looking at that hateful error message. I found this info on someone's blog. I'd link to the original blog post, but unfortunately I lost the link. But the blogger had said that apparently, we need to add the $ sign to enable the mac to realize that what is being entered in a hexadecimal key (?). I believe this is what s/he had said.

Oh, and also, while you are tweaking your wireless settings, you might also want to check whether your router has been set to allow all MAC addresses or just a selected few. If you don't want to allow access to all MAC addresses (allowing access to a selected few gives you a better level of security), make sure you enter your mac's unique MAC address to the list. I learnt about this the hard way!

Hope this works out for you! Good luck!

I also have a new macbook running OS X 10.4.10. I've looked in other forums and a lot of other people have problems getting on google and some other sites by wireless. Many have complained about google. Google, gmail, and sometimes even this site refuses to load when I'm on wireless. Someone said that everything was working fine until they updated to 10.4.10. I lose my complete connected sometimes (I'm the only one in the house that does) and sometimes google works for a few minutes when I restart my connection my airport connection. For now I'm just using an ethernet cord when I want stable internet. Waiting for a software update and hoping things will be fixed....

my mac book will not connect to network

For some reason, my mac book will not connect to my home network. When I enter the password it comes up with connection timeout.

Have you tried resetting the router?

You may want to consider changing what channel the airport is on. I don't own an Apple access point, but I have significant experience with wireless deployments. Often slow, unreliable connections can be the result of too many devices on the same channel. Go into the setup for the router and select a different channel. In 802.11 B and G, the best channels to use are 1, 6, or 11.

Wireless Issue Solved by clearing "plists"

I had a similar problem where my macbook pro suddenly stopped connecting to wireless networks that I used all the time at work and home. It would find them but the signal strength bar would just cycle through and then I would get a "connection timeout" message or "another device is using your IP address."

Anyway, I went to the mac store and they fixed it in 10 seconds by clearing my "plists." I made him show me where this was located but I'm not exactly sure which plists you are supposed to clear (he cleared them so fast). If you go to your Macintosh HD located on your desktop or in finder under devices, got to Library-->Preferences-->System Configuration and you will find a lot of "plists" related to your airport and network preferences. Sorry I didn't get the specifics but I hope this helps.

Warning: When I asked the apple guy what he had done, he said to be careful clearing you plists bc you can mess things up.

Similar Problem

I had a similar problem until about 5 minutes ago. My problem was as follows:

I've owned my macbook for about 2 years, and suddenly yesterday it wouldn't connect to ANY of the networks I've been using regularly since I bought it. I kept getting "Connection Timeout" everytime I entered the password to a network.

I fixed it by doing the following:

System Preferences -> Network -> Advanced -> 802.1X tab
One the left panel of this tab is a list of user profiles, containing the usernames and passwords you use to get onto secured networks (such as university networks that require a username/password after you log in). Delete all profiles. Click okay, then Apply, and you should connect.

This may not be the same problem as yours, but can be worth a shot anyways! Deleting those profiles won't have any harmful effects, you may just have to resubmit your username and password to any secured networks you use frequently. Good luck!

Same Problem not loginning in...Think I have a solution!!!

I have had the same problem with my MacBook. It is now working!!! I was able to login to my wifi before on my computer and then all of a sudden I couldn't login anymore. It would show an exclamation mark on the wifi logo. For some reason my computer changed the password on me (I didn't do it!!!)

This is what I tried. I hope it works for you:
1. Turn Air Port off.
2. Open Network Preferences
3. Uncheck remember networks this computer has joined.
4. Press Ok and then Apply.
5. Turn Airport back on and retype your password and click join.

If this works then your password may be saved wrong in the Keychain Access application.

6. Go to the spotlight and search Keychain Access.
7. Under Passwords go to your network and double click on it.
8. Click show password
9. Type in your login password (what you use to login to your computer/account)
10. Click Always Allow
11. Change Password if incorrect.
12. Save changes.



If that didn't work try creating a new account and see if you can login from there.

I hope this works,
Christina

Squashette44's solution worked

Thanks, Christina! I deleted the password from my Keychain, reconnected and re-entered my password, and it worked fine.

same issue

Thanks Christina!

It worked perfectly well for me, too when i was experiencing the same problem but with a few different aspects.

My MacBook pro was not automatically connecting to the internet when I would open it to use it, and I would have to manually reconnect every time, and it was becoming harder to reconnect, saying there was a problem with my connection.

I followed several instructions on here, and Christina's instructions worked perfectly!
Thanks again!

I've been having a problem too. I used to be connect to any of my wireless networks even after I installed OS X (Lion). Over the past few weeks however my MacBook just won't connect to my wireless router. Sometimes when I load it up it works fine, but other times it just won't connect. I turn the wifi on and off and I find the network, I click on it but nothing happens until I get a timeout error.

I've tried these solutions on this forum but none have worked/not been able to try them.

I think this is a more recent software bug so any new help would be greatly appreciated.

Oh and I don't think I need any solutions with regards to my router, as my roommates PC works with no problems on our network. It's just my MacBook.

Thanks,
Lewsh

connection timed out

My new Mac mini suddenly gave me this message, but my hardwired old Macmini did not. And my MacBook got the same "connection timed out" message, but was able to connect to a neighbor's open WiFi. Fiddled with some of the other suggestions above, but finally figured out maybe the problem was the router. Turned everything off. Pushed the reset button on the Linksys router. Lights came on. Fired up the computers. All worked fine. Wish the human body was so easily healed.

...

Ok! Same problem in a worst case scenario.

I have a macbook air, yesterday I decide to reset it to factory default. Till there no problem, I reset it using the apple assistant. Then I tried to re-install Mac OS Lion, guess what!? My macbook won't connect to any wi-fi connection...

I don't know what to do... I'm stuck on a screen where the only thing I can do is choose a internet connection and nothing else!

Any one has any ideia what I can do to solve this problem?

Cannot connect to Wifi network

Hey guys! My Macbookpro 09 had been connecting to the network fine, my father set up a new network, his computer logs in fine, I however cannot connect to the internet. It states invalid password but we are damn sure it's right especially after entering it numerous times. I have no idea why this would happen. Any suggestions or help would be great! Thank you!
