IMac can connect to wireless network automatically

All of a sudden, my mac won't automatically join my wireless network. I can find the network easily and connect to it, but it doesn't connect automatically like it used to. This seems odd as iphones have no problem finding the wi fi network and connecting. This seems to have cropped up after I added another user account, but that may be totally unrelated. Any ideas how to fix this? Let me know if there are more details I can provide. Thanks.

I've had this same thing for months now and I have no idea why. I do know that it started right around the time that I upgraded my iMac to Snow Leopard, but laptop (Pro) is still just regular old Leopard and it happens with it as well. I've tried everything - the approach in the previous reply to your question included - and have still had no luck. I tried all the old (2008, etc.) apple discussion forum stuff too. No joy. Please let me know if you figure it out because at this point in time I've tried everything I know. Granted, selecting a network every time I power up or wake a computer from sleep is not going to kill me, it's just....annoying.

IMac cant connect to wireless network but PCs can

A problem has occurred following some software updates on my iMac. I cant access the internet whilst the PCs can. The network was previously secure but I have unsecured it in an a futile attempt to fix the problem. When I go into Network diagnostics the 'enter airport information' box says the network requires a password. There is NO password; it is unsecure. The previous password I had does not work when I input it. I would like to solve the issue; worst case scenario is there a 'system restore' to a previous date like Windows?
Thanks
P.S. the airport is showing connected to the network on the top right status bar but I cant access the internet.

Take a look at my FAQ:
http://www.macmaps.com/WIFI1048.html
There is no "system restore" as such. If you didn't make a backup before you updated, you might want to get an external hard drive and install the operating system on that, and recover information as needed, as my FAQ explains:

Can connect to wireless network but no internet access

I have a PC that runs on Windows Vista and a wireless network using Airport Extreme. My PC can connect to the wireless network but I cannot access the internet. Windows Network Diagnostics states that 'A problem with your network router or broadband modem might be preventing an internet connection'. There should be no problem with my modem as I can access internet using my powerbook. When I run airport utility on my PC, there is an error message that states that 'An error occurred while trying to access the Apple wireless device. Make sure your network connection is valid and try again', 'error -6753'.

I am glad you brought this up. I am having the same difficulty. I run an iMac OS X 10.5.6 with an intel processor and a parallel system to get me on the Windows side. When I try to access the internet using my Airport extreme I cannot access any sites and the internet explorer page pops up with "The page cannot be displayed and sends me to try the diagnose connection problems on the toolbar method. However I can see my base station and all looks fine with the information there. I can also access the internet from my mac side of the computer. It would be nice to use the Windows side to gain access to the net because I have programs for the windows side that need updating. Anyone out there have any suggestions?

Can connect to wireless network but not to internet

Ok, so I bought a new AEBS and have finally managed to get it set up with my cable modem, and with security on so that the light is green, and not amber... the only problem now is that although I can connect to the wireless network that i have created using the base station, I cannot connect to the internet through it using my MacBook.
I don't have problem connecting my iMac to the net wirelessly using the base unit so am confused.
Anyone got any ideas?

Connecting to wireless Networks automatically upon boot

Hi there all,
I have a G4 Laptop with a Airport wirless card in it. I have successfully connected to my wireless network in my home, but I was wanting to automate this process upon booting OSX. So what I want to know is how can I config OSX so everytime it boots, it will automatically connected to my wireless network(without manually doing it)
Thanks for the help!

Hello jlfutari. Welcome to the Apple Discussions!
So what I want to know is how can I config OSX so everytime it boots, it will automatically connected to my wireless network(without manually doing it)
First, create a new Location with your Wi-Fi as the "Preferred Network."
Create a new network Location w/Preferred Network
o System Preferences > Network > Show > AirPort
o Location: New Location...
o Name your new location: <enter a location name>
o Click "OK"
o Click on the "AirPort" tab to select it.
o By default, join: Preferred networks
o Select a "preferred" network from the list, or click "+" to add a new one.
o Click "Options..."
o If no preferred networks are found: Ask before joining an open network.
o Click "OK"
o Click "Apply Now"
Second, setup AirPort to default to the "Preferred Network."
System Preferences > Network > Show > Network Port Configurations
o Verify that AirPort is "On" (checked)
o Verify that AirPort is at the top of the list. If it isn't, you can drag it to the top.
Systems Preferences > Network > Show > AirPort

o By default, join: Preferred networks

IPod Touch suddenly no longer can connect to Wireless Network.

Hello, I have yet to find an answer to my problem so maybe you guys can help.
I have had my iTouch for at least 2 years and have never had a problem with it, and constantly used it to connect to the wireless network in our home.
However, starting two days ago, my iTouch can rarely detect the network (even when right next to the router) and if it does, it is unable to join because it loses the signal almost immediately. After much troubleshooting, (laptops connect fine, friends iTouch's connect fine) I have determined that something is wrong with mine.
The only thing I can think of that happened that day, was that night it had gotten extremely cold. (Montana, oh yay.) Could this have caused the malfunction?
Any insight would be appreciated!

Given that it got really cold and you brought it inside, condensation could have formed on the inside bits. Dump it in a bag of rice or a jar with those silica gel packages for a couple of days and see what happens.
If you still have problems connecting, try power cycling your router and resetting your touch's network settings.

WRT54G v6 - Can Connect to wireless network but can't access internet

Ok, this is my last resort for help. I spent two hours yesterday with linksys "chat" support to no avail.
First the techincal details:
OS for all machines = Windows XP
Laptop w/two adapters - one wired, one wireless
WRT54G v6 upgraded with 1.00.9 firmware
SpeedStream modem from DSL provider
I have manually set the IP, subnet mask, gateway, primary and secondary DNS for my wireless adapter (using the Alternate Configuration in the Internet Protocol Properties of the Wireless Network Connection). When I connect to the wireless network I see that the IP, subnet, gateway and DNS server IPs are all correct (via ipconfig /all). I see that I am connected to my SSID (11.0 MBps, signal strength Excellent) however I can't access web sites (the server not found message appears in the browser) nor can I ping the router IP or any other IP (LAN or WAN).
My wired PC works fine with this router. My laptop works fine with this router when wired.
Anyone face a similar situation and have a solution? Thanks.

A new discovery...
When I disable the wireless security on the router, I am able to connect to the wireless network, ping the router and access the internet. So, there is apparently something wrong with the WEP security (although I am able to connect to the wireless network when WEP is enabled).
I am thouroughly confused. Any help is appreciated. Thanks.

Can connect to wireless network run off dell router, but not internet!

I have a iBookG4 and have moved to a new apt with a wireless network run off a dell router/ comcast. My roommates have both Macs and PCs and can connect with no problems. I found the network on my airport and put in the password, joined network no problem, but cannot connect to the internet. The Airport status is yellow and says that Airport has self assigned IP address and cannot connect to the internet. I can connect fine to other open networks in the area so its not my computer. I tried to copy the IP address from my roommate manually to the network settings but that didn't work either. What am I doing wrong? No one here seems to recall how they set up the network and I am paying for a network I can't access. Please help!!!

Does the dell router have an access list set-up?
With an access list (depending on the router) it can be set-up to allow access for only certain MAC addresses. If your MAC address isn't in the list, you'll not get on.
Usually the router will have an IP address itself of 192.168.2.1 or 192.168.0.1 - depends on the router. You should be able to determine it from the IP address your computers are getting. Try getting someone to connect to this through a browser, and check/change the configuration of the router directly.

Can connect to wireless network but no internet?

Ok, I'm sure this is answered somewhere, but I'm tired.
At this point I'm not even sure if it can be done. But... I tried to connect to my mother's wireless internet using my Airport Extreme. I connected to the wireless but was unable to access the internet, or email. I tried manually setting the IP address, DHCP, router, DNS etc. But to no avail. It kept saying "Airport is connected to wireless ..., but it has a self-assigned IP address and may not be able to connect to the internet". I got it to accept the new IP address and finally it said " Airport is connected to wireless..., and is connected to the internet" but I still could not get on. It does say on her computer that it is protected by a key. But I used her password to get on and it recognized it? But her password was not the key.
I thought that I could connect to any wireless network with the password?
Can this even be done?
Thanks
A

Duane,
Thanks for the response. I did not see anything about MAC filtering enabled. It did say encryption was enabled. All I foud was the IP address, router, DNS etc. It is a WEP password and it did accept the password to log on to the network. It's Time Warner and she has a PC. I tried everything, set up new location. I'm going to try to log on to my friends wireless network and see if I can do so there. If my memory serves me right, the last time I tried to log on to a wireless network it didn't work either. Also my mother does not know much about it, someone set it up for her and she is one to not understand these "new fangled things". So...

Officejet 6600 All But One Laptop Can Connect To Wireless Network Printer

One windows and 2 macs can connect to the wireless printer over the newtwork just fine but one (Windows 7) will not. HP Print and Scan Doctor can discover the printer from that laptop as "visible" but repeatedly says " need to install full software" which I've done, and after, it runs install wizzard reports, the IP address I've entered is wrong, which it's not. Firewalls are off. I've un and re installed, tried windows add device which can't connect either. I've had this problem before with this laptop but just can't remember how I fixed it. I remember getting to a screen that offered the option of installing over a nework or wireless directly to the printer and over the network fixed it, but I can't remember how I got there. Any ideas as I'm at wits end. Thanks

Welcome to the forums @Davidchicago ,
I read through your post about the installation troubles you are having with one of your Windows 7 computers and your Officejet 6600. I am here to let you know what my suggestion is for you!
There could be a program blocking the installation and causing the problem. I'd recommend a Clean Boot, restarting your PC, disabling your firewall and running through the installation again.
Hopefully that will get you through the install. Let me know the results!
Have a great weekend

I can connect to wireless network, but it doesn't work

I am able to connect to my wireless network from my iPad and iPhone, but it's not working.

If you are able to connect to your wireless network as you state.....then can you provide more details about what is not working?

NB200 Can connect to wireless networks, but cannot connect to the internet

I have been able to connect my Win XP netbook to my secure wireless network at home, other people's networks and public networks like the library and McDonalds. This week I'm away from home and discovered that while I can still connect to a number of different wireless networks, I cannot connect to the internet using Internet Explorer.
I've had this problem once before and fixed it by reinstalling Windows XP and all my other software. I have no idea why it has happened again. I'm hoping for a less drastic solution to the problem..?

Hi Nakia,
> I cannot connect to the internet using Internet Explorer.
Have you tested other browsers like Mozilla Firefox and does this work?
As MasterG wrote try to renew the IP address using the commend line.
Last week I had a similar problem and I could solve it by updating the WLAN driver. Just remove the driver, restart the notebook and install the newest one. :)

Macbook Pro Doesn't connect to Wireless network automatically

I just enabled WPA encryption on my router and now my macbook won't automatically connect to my router. I have to select my router in the wireless menu and then it joins. I don't have to type in my encryption key, I have my key stored in my keychain. Before I enabled encryption my macbook connected just fine. I'm have 10.4.11 and a D-Link DIR-655 router.

Could be a corrupt preference file. Not sure which one is relevent here. It may just come under the general Finder prefs. Have a look in User>Library>Preferences for anything wireless related. If nothing shows, try dragging com.apple.finder.plist to the desktop, then either relaunch the Finder or log out and back in. If no change just put it back and choose 'replace' when asked. If you find something more appropriate try that too. Not at a Mac right now otherwise I'd be a little more helpful.

Can I connect to wireless networks far away?

How do I connect to wireless networks further away?
Is there a way I can improve my laptops wireless range so I can connect to wireless networks further away?

Hi!
You can only connect to wireless networks that the notebook recognizes. If the notebook recognizes a wireless network, you can connect to them. If it doesnt recognize (because it is further away) you can not connect.
Furthermore you can not improve the wireless range from the laptop. You can do this on a WLAN router, not on the notebook.

Impossible connecting with wireless network Netgear WNR 2000

I can not log on to my wireless network (Netgear WNR 2000) with my macbook. My other PC:s work fine and connect always. My Macbook only connect after I have restarted the router. When I use my Macbook in other places I can connect with wireless network. What is the problem?

I'm assuming that you're using the right network password! After that, the most common causes of difficulty are:
- The router not set up for DHCP and so cannot allocate an IP address to the MacBook
- The router has "MAC" Address Authentication (a security feature - don't mistake MAC for Mac[intosh]) turned on and the AirPort MAC address isn't in the pass list.
- The default "Automatic" location in System Preferences > Networks has been modified so that it no longer works.
