Macbook Pro can't see wireless network or connect to it, but iPhone can!?!?

ok here"s the deal:
I got my macbook pro in the states through school and it has been working fine ever since. I now just moved back home to Germany and for some odd reason the wireless network at home at my mom's won't appear in my "join network" list.
I have tried diagnostics and advanced stuff, I have even typed in the network name and password into my preferred networks list manually... still nothing. When I connect the computer through an ethernet cable it works just fine. also searched and updated all my updates in case that was maybe the issue...
here's the clue. my sister and her friend both also have macbooks (not pro's though) and both also run leopard and both of their laptops can see and connect to our wireless just fine. ALSO I have an iPhone, I purchased in the states and it can see and connect without any issues as well..
I have called the German Apple support people, but they are absolutely useless and there are exactly 2 (!!!) genius bars here in Germany. one 4h and one 6h from where I live... sighs
this is what I found in my about section, in case anybody knows what this means:
+AirPort Card Information:+
+Wireless Card Type: AirPort Extreme (0x14E4, 0x8C)+
+Wireless Card Locale: USA+
+Wireless Card Firmware Version: Broadcom BCM43xx 1.0 (5.10.91.21)+
is it because it says "USA" and I am now in Germany? but how stupid would that be? other people that bring their American macs over don't have issues either... right???
so yeah... HELP??? ANYBODY??? PLEASE???

Hello,
I had the same problem when I was traveling with my 2009 Macbook Pro. I am on a French ship and my MacBook was bought in the US. We have a wireless gaming network to play Call of Duty on that is set up on a LinkSys router. I was so frustrated because everyone else here could connect and play without a problem. My iPhone would even connect to the network but my MacBook Airport card wouldn't even recognize the network.
It turns out that some countries use different Wifi channels. The Airport card in the US MacBook Pro is setup to only recognize channels 1-11. The European LinkSys router was broadcasting on channel 13 which is why my MacBook couldn't even see it. I changed the wireless channel on the router to 10 and now everything works great. I hope this works for you.
Cheers
P.S. - The US MBP can only recognize channels 1-11 on a standard 2.4GHz network. To see what channels your Airport Card will recognize, open System Profiler (located in the Utilities folder) and find the "Network" heading in the column on the left. Click "Airport" and it should display all of the supported channels in the info box to the right.

Connecting a macbook pro to a verizon wireless network

how do i connect a macbook pro to a verizon wireless network? Wi-Fi connection automatically assigns an IP address and indicates that the Mac won't be able to connect to the internet. Two other MacBook Pros connect to the network without any problems. These Macs travel from home to school and back again and automatically reconnect when they are brought into the house.

I have read a few corporate IT policies and they are all PC-centric.
Unless your mac runs any windows tools such as Bootcamp Wine, Crossover, or a VM in parallels or VMware then your mac has no virus implications.
A few years ago word documents could be infected with macro viruses and although did not affect a mac a mac could pass them on. Up to date versions of Microsoft Word documents are not vulnerable to this flaw.
You could install ClamAV its a free anti virus app for the mac that would keep your IT dept happy.
Maybe I can find out what the WEP key is with a utility of some kind.
If you had a compatible usb wifi dongle and kismac you could crack their WEP key but this would be probably illegal in your country so I dont condone this activity but if you got written permission from your employer to give them a free penetration test, something that normally involves hiring a security company this would save them money and highlight the insecurity on their network.
Or use an Ethernet connection.

I'm having problems printing from my 15" macbook pro to my HP wireless printer. It works sometimes but not reliably, it can spend hours "seating for printer". I can print from my i pad with no problems

Hi,
Apple's AirPrint only support specific models while using wired or wireless network connection.
Plugging a printer into a USB port of Apple base is not supported for AirPrint:
AirPrint printers connected to the USB port of the Apple AirPort Base Station or Time Capsules are not supported with AirPrint.
As well you must use AirPrint enabled printers for a such, none of your printers are AirPrint enabled:

There are 3rd party solutions which allow sharing a printer connected to your Mac as AirPrint, Printopia as example provide a such:

MacBook Pro fails to see one network

In one room I have a Time Capsule broadcasting both a 2.4 gHz & a 5 gHz network. It's also connected by ethernet to an Ethernet Over Power adaptor which communicates with a second one in different room, which then broadcasts another 2.4 gHz network.
I have an iMac in the second room next to the EOP box and it sees the network from that box, plus the 2.4 gHz & 5 gHz networks from the Time Capsule in the other room.
I have a MacBook Pro sitting next to the iMac and it, too, sees the network from the EOP box, and the 5 gHz network from the Time Capsule, but it doesn't see the 2.4 gHz network from the Time Capsule. In fact, even if I put the MacBook Pro next to the Time Capsule, it doesn't see the 2.4 gHz network, yet it sees and connects to the 5gHz network and, when it's in the other room, the 2.4gHz network from the EOP box.
Does anyone know why the MacBook Pro doesn't see just this one network?
Thanks in advance,
Steve = : ^ )

Something to test
Click the Apple logo at the top left, hold down the option key, and About this Mac will change to System information.
In this window, goto the wifi and see if the network your missing is listed here.

Macbook Pro will not remember wireless network

We have two Macbook Pros and are having issues with one of them not finding and then not remembering a particular wireless network. The other one works normally on this network, as do our iPad and iPhones.
The problem Macbook Pro will find a number of other wireless networks in the vicinity, but not the one we wish to connect with. However, when the required information about the network is entered into the Network Preferences, it does see the network and will connect with it, until the computer is shut down. When it is powered-up again, the Macbook will not find it, even though, in theory, it had been told to remember it and that network had been moved up to #1 in the order of priority.
The settings on both Macbooks are the same, so why can one find and remember the network and the other not? What can I do about the problem?
Help please!

Settings for wireless network connections are actually stored in two separate places on your Mac, so in addition to the correct advice offered by Jolly Giant, you will also need to delete old network listings in KeyChain Access.
Macintosh HD > Applications > Utilities > KeyChain Access
Locate the name of the wireless network that you want to delete and click it to highlight it
Click Delete on your keyboard
It would be a good idea to go ahead and also delete the current connection as well in case it has become corrupted. This will clear out the old settings and when you next connect to the network and enter the password, the new settings will be preserved.

Mac can't see wireless network - have checked other posts but no solution!

I have scanned many posts on this topic but have not seen my specific problem resolved, so I'm starting a new post. Here's all the facts and things I've checked.
Hardware Details
iMac 1.25 GHz G4
Airport Extreme card (shows up in system profiler)
Linksys 802.11g router
Network Details
WPA Personal
Have never had a problem using this network. 2 PC's an 2 Macs regularly connect. Right now one PC and my wife's MacBook Pro are using the network.
The iMac was seeing the network yesterday - today it can't even see it!
Per the advice from many helpful posters, I have checked that mac addressing is disabled on the router.
I have checked that appletalk is active on the iMac
I have restarted the iMac several times after applying various changes.
This is a very perplexing problem. Any help would be appreciated.

Hi kmacwilliam,
I am having a similar issues with yours, my MBP and MB couldnt not stay connect to the dlink router recently. But the PC's been working fine all the time. The wireless would drop and could not see the network again while my neighbours' networks were still displaying. Even restarting the MBP and router wont see my wireless network.
You can try these things and see if it works for you, it's worked for me for time being. Please post back the outcomes:
1. Delete any airport-related passwords in the "Keychain" so no airport passwords are stored
2. Shut down the iMac
3. Reset the PMU in your case for the G4 iMac, you may need to open your back case to reset it
3. Turn on your iMac and you should see the network again
I am suspecting this might be software issue, hope this works for you.

MacBook pro does not detected wireless network?????

Hi! I have an airport express that provides the wireless network for the house. My iMac and iBook as well as iphone have no problem detecting the network. But the network does not show up in the drop down list that shows up when I turn the airport on. When I click on "other" and type in the information that way, the connection times out.
Any suggestions would be appreciated!
Thx!

I have a similar problem. When I set the network to not be closed, My MacBook Pro finds and connects when I return from being away. When I set the network to be "closed", it will not connect automatically (I have checked "Remember and network this computer has joined" & "Remember this Network ") it will not join automatically. However, when I enter the name and password, it connects and all is well. My iPhone will automatically connect regardless of the "closed" being checked or not. Any suggestions? I would prefer to retain the "closed" setting for extra security.
Thanks,
Bruce

MacBook Pro (Retina) Wi-Fi Drops Network

My MacBook Pro keeps dropping my wireless network, which is broadcast through the new Apple router tower. Is this a problem with the Mountain Lion Wi-Fi software? Any fixes or patches?

(Repost from another Apple message board)
Had the same pervasive problem (inexplicable dropped internet connection at random times requiring restart) with a brand new flagship stock model 15.4 inch late 2013 Retina Macbook Pro with Graphics card purchased in December 2013 from local Apple store (Intel chip = Crystalwell version). Ongoing problem started about 2 weeks after initial purchase, and would happen with both Wifi **and** (I discovered yesterday) Ethernet connections. We have the latest Apple Extreme and multiple Expresses running 802.11n at home with 75/25 Verizon Fios internet speed.
Apple Care phone tech support over past 10 days of little help. Scoured these message boards for a solution - none found.
So, I took to local Apple store 1/12/14. Thankfully, problem cropped up in-store. As such, "Genius" turned off Kaspersky virus protection. Problem remedied itself **instantaneously** and has not happened since. No restart was needed.
Theory: appears 3rd party software (in my case, Kaspersky) in some way is interfering with new Crystalwell/Haswell chips.
Regardless, so far, so good. Hours of continuous internet...and counting.
Will post an update if this happens again.
Good luck.

MacBook Pro can't see Airport network but three other macs in house can

Very strange. I can connect my three iMacs (G3, G5 PowerPC and G5 Intel) to my Airport Extreme Network, but my MacBook Pro can no longer see the Network, and Airport utility (from MacBook Pro) cannot see the Airport base station (although other macs' Airport Utility can no problem). My MacBook pro can see 4 other networks (my neighbours' networks). Doesn't seem to be a problem with my MacBook Pro airport card as I can connect to the (non-Mac) wireless network at work with no problem. Am really confused (not the first time)!
Installed the latest Airport Extreme firmware last week, which was the start of the problem, as I then lost the ability to connect to my Virgin Media Broadband digital TV box, necessitating Virgin engineer visiting at weekend to connect a cable modem to the cable tv box, to which the Airport Extreme station is now attached. Had problems connecting my MacBook Pro last night, but eventually managed it. All other macs connect seamlessly. Am stumped.

I'm troubleshooting a friend's MacBook (Model ID: MacBook4,1) that is having serious Airport problems. This machine's Airport can't see ANY available networks. Sitting right next to my MacBook (identical model), hers is blind while mine can see several open and locked networks including my own Airport base station. If I choose to "Join Other Network..." and enter the network name and password for my network, her machine almost immediately gives me a "Connection timed out" error. It doesn't matter where her MacBook is, it can't see any networks anywhere.
This is a new problem as her Airport was working fine for the first few months. I've just finished making sure all software updates have been applied so she's now running the latest-greatest, but still no Airport.
This sounds similar to the problems other folks here are describing so I figured I'd add my voice to the chorus. I guess I'll take her machine down to the local Apple store this afternoon and see if they have any ideas. At this point I wouldn't be surprised if her Airport card was fried.

Change your router channel. Sometimes this is all you will have to do.
Power cycling the router. Read the router's user manual or contact their tech support for instructions.
System Preferences/Internet & Network/Network
Unlock the padlock
Locations: Automatic
Highlight Airport
Click the Assist Me button
In the popup window click the Diagnostic button.
System Preferences/Network- Unlock padlock. Highlight Airport. Network Name-select your name. Click on the Advanced button. Airport/Preferred Networks-delete all that is not your network.
Place a check mark next to "Remember networks this computer has joined." Click the OK button and lock the padlock. Restart your computer.

Check to see if an extra entry is present in the DNS Tab for your wireless connection (System Preferences/Network/Airport/Advanced/DNS).
Delete all extra entries that you find.

My macbook pro can see my home wi-fi network but cannot connect to it. My iphone and ipad are connected to my home wi-fi so the problem is not the modem.

Wow, I tried to submit this as a problem and the computer lost the wifi connection again, so i lost the whole explanation i typed up.
I've turned off computer and modem multiple times.
When I tried to run the network diagnostic, the macbook pro gave me a "perhaps you are out of range error". I am sitting next to the modem.
My iphone and ipad are wonderfully connected to the home wifi network, so it cannot be the modem/router, correct?
If I am on the same floor as the router/modem then the macbook pro can see my home network but after tyoing in my password and trying to connect i get a "timed out" message.
If I move down one floor, then the macbook can see and connect to the wifi. I only have one modem on one floor.
Is there some sort of diagnostic I can run to see why this particular device (macbook pro) is behaving ths way? It just seems weird because the computer could connect to the wifi network yesterday while i was sitting next to the router.

SOLUTION!
I've been suffering from this problem for a few months. I tried everything suggested by everyone, and then, today, I had a mad idea.
I used to work in a room in the house that's about 12 metres away from the router. It's on the next storey up and horizontally about 8 metres away. The problem started when I began to work in the same room as the router.
Today I became so frustrated that for some reason I walked into a room about 8 metres away on the same level - Guess what? I connected with no problem at all. Feeling full of joy I walked back to the room where the router is located - Dropped internet connection within a few minutes! Walked back to the the room that's 8 metres away and, hey presto! I have a connection. I now realise that the problem was that I moved too close to the router.
I can think of no logical explanation for my experience, but empirically it seems to work. Does anyone have the faintest idea of why this should be the case? In the absence of an answer I think I may have to start believing in fairies at the bottom of the garden - I'm just off to set a meal for them.
By the way, I don't know if it has any significance, but the router is a BT Infinity router that has replaced the incredibly unreliable Virgin Media cable connection

I connect my macbook pro to an Epson wireless projector. The macbook can see the projector wirelessly and the image on the macbook is displayed on the projector. However on system ref., the arrangement tab does not show and thus cannot have multiple view.
I am trying to project Pro Presenter on the Epson projector such that I have the detail screen on the macbook and only the screen I want people to see on the projector display. This has not been possible because the arrangement tab on the Display section of the System Preference is not showing. If i tried to search for the arangement, it comes back with the message that there is not other source detected, hence the arrangement tab is not showing.
I have also tried to connect the Epson directly to the Macbook but it still the same result, so its not because it is a wireless connection. Can someone advise me jhow to go around this problem. I have used windows before and it is very easy to extend ptojection on windows, but this system seems to be frustrating to me.
Thanks,

Macbook will not see wireless network

My new Macbook will not see my wireless network. My Windows 2000 PC, my Ipod touch and my Macbook Pro (jaguar) all see it no problem and work well with it.
I have tried entering the network name manually and it does not work. I have WEP password protection.
The macbook sees and connects to all other wireless networks I've encountered (father-in-law's house, Airport departure lounges, hotspots etc.). The macbook also sees my neighbours networks no problem.
I am confused, please help.

I am having the same issue, a friend visited with his new Mac Mini, running Leopard, and it would not see the wireless network, that 3 other macs (PowerBook G4, iBooks G4 and G3) running Tiger (10.4.11) and Windows machines recognize without problem.
I'm wondering if the issue is Leopard and 3rd party routers or MY router in particular, as I have a US Robotics 5461, and I remember when a previous roommate replaced her G4 iBook, running Tiger, with a MacBook Intel running Leopard, she also had issues connecting wirelessly.
My friend's Mini had no problem recognizing all the neighbors networks (at least 4 or 5) and I'm pretty sure they are not Mac users with an Airport Base Station.
I was hoping to upgrade my G4 PowerBook (once I get it repaired) to Leopard in the future, but I don't want to lose the ability to connect to my wireless network.
Has anyone running Leopard run into this problem and found a solution?

New Macbook Pro Can't See Other Macs

My Powerbook and iMac can see each other over the network and do file transfers, but my new Macbook Pro can't. The other computers show up in Bonjour Browser, but when I try to connect to them (either via their computer name, e.g. my-computer.local, or by ip) it can't. It tells me the address is wrong. It can't even ping them, and they can't ping it. It's weird because I can access both the internet and the router settings.

After I did that Airport stopped working. The menubar icon said "Airport not configured" and there were no network interfaces in System Preferences. So I tried just putting the airport prefs back, and restarting. The same thing happened, so I had to put the whole folder back where it was.

Macbook Pro can't see wireless network or connect to it, but iPhone can!?!?
