MacBook Pro Can't find home wireless network

I've been having some issues getting my macbook pro, running OS 10.7.5, to find my home wireless network. The network doesn't show up when it searches automatically, and when I type the network name in to find it manually, it says no network found. The computer connects to all other networks and finds then with no issues, and other MacBooks are able to find my home network and connect to it again with no issues.
The computer used to be able to find the network, and then it just stopped working. I have tried all the standard fixes, resetting the router, computer, PRAM, forgetting the network, deleting the key from keychain, but nothing seems to work. I tried googling the issue, but wasn't able to find a problem similar to the one I have.
Any advice would be greatly appreciated.
Thanks

Still having problems with this.
I have upgraded to Mavericks, hoping that the problem would be fixed, but it hasn't. I still get all networks completely disappearing - even if I search for them they are not found.
But I reboot the computer and it works! But when I am in OS or Bootcamp mode and put the Mac to sleep, it does not see the networks again! I have to reboot the computer for it to work.
I have even got a new router which can receive the b,g and n signals etc. as I was told by a Mac techie here that Macs 'look' for the n signal but can also work with the b and g signals and THAT maybe my old router only transmits b and g or something like that .
This, to me, sounds like a Mac software problem. I had a similar problem on a previous Mac on my "old router" and a totally different router in a different country's telephone system.
I now have the same problem with a new MBP on a new router!

Macbook pro can't find preferred wireless network

My father signed onto my wireless network using his own laptop (PC) with my passkey. Then after he had been on I tried to connect to the internet with my macbook (and iPhone) and my network was gone. If I look at the list of available networks it lists my neighbor's (which usually doesn't happen) and the name of my father's computer but ours is gone. If I go to my preferred networks, I see mine listed but then when I try and connect to it is says it cannot be found. I tried creating it again but then when I enter the password it says it's invalid. I tried connecting to the network under my dad's computer's name to see if somehow the name changed on its own but it says invalid password as well. Any ideas?

"If I look at the list of available networks it lists my neighbor's (which usually doesn't happen) and the name of my father's computer but ours is gone."
Your father's computer should not be showing up in the list of networks unless he mucked around with your router. Log in to your router's admin pages and see what the issues are.

MacBook Pro only can't find home wireless network

Hey guys!
I purchased a 15" retina MacBook Pro by July. It brought Mac OS X Lion with it: I had no problems.
However, more than a month later I upgraded to Mountain Lion, and I started to have the same problem ALWAYS: sometimes I would be connected to my home wireless network, perfectly fine. However, after shutting down, sleeping, etc, whenever I would turn the Mac on again, it wouldn't find my home network wireless anymore, but it would find e.v.e.r.y and other network available. Also, my phone, iPad, and every other equipment, would find it and work perfectly. After several restarts and wake ups from sleeps, the Mac would eventually magically find it and stay connected for an unpredictable amount of times (sometimes it could find it continuously for some days after some sleeps, and sometimes it wouldn't be found again after some hours of it being found again (assuming the computer went to sleep)). But if I try any other of the available networks it connects with no issue!
And I've been in this game constantly! I've tried (almost) all the Mountain Lion wifi-related posts in the Internet, but none seems to solve it.
I have only found a few posts with my related issue, which I recall: the Mac won't find, ONLY, my home network, while any other equipment can, and it can magically find it occasionally, lasting its connection until the next sleep or shut down.
Help would be really appreciated.
Thank you,
Juan

Hum, good point, the problem may lay with the router compability. My sister, who has ML as original OS has been having the same problem of not finding only our home network, so it seems that the problem lies on Mountain Lion compatibility with the router. I just restarted the router several times and we both got internet at the same time. The question is, as always, how long will it last until it won't find it again.
Now, focusing on the router.
Here, in Portugal (as for the rest of the world I don't know), the Internet provider companeis offer their own modems. Not only that, as those modems are both: modems and routers ( http://imageshack.us/scaled/landing/149/ofibrasjaestaabombar.jpg ).
After writting the above, and re-reading what you said, you lighted me up the idea of entering the modem domain (you know, that url you put and have access to every definiton of the router?)
Well, the password "type" was selected to "WPA and WPA2". What I did was selecting "WPA2" only. So far it seems that it is working. I'll do some restart tests etc etc and I'll let you know! (Maybe the problem may persist, but I'll only know days from know as it may seem, for know, that it is solved.)
I'll let you know, and thanks for the help so far, Sig!

Macbook PRO can't find ANY Wifi network - only at home

Hi, i have a very strange problem with my *Macbook Pro*. I have 3 apple computers at home and one pc. On all machines Wifi works fine, except my new alu Macbook Pro. Important note is, when im with my macbook on other place, office, caffe, *Wifi works fine. But when im at home, this macbook simply can't find ANY network, it's blind.* Interesting thing is, all other computers are several years old and WiFi works fine on them. My friend also bought a brand new macbook pro, and this machine also couldn't fine any network at my home, or in other case when it found networks, it couldn't connect and recieve error message "Connection timed out". I noticed there is new Wifi network in our range, is it possible that this network can cause "blindness" on new macbooks?

*I have to say, I'm really glad you are trying to help guys.*
Well, router is almost on default settings, SSID is brodcasted and i'm not filtering MAC adresses. I tried changed channels, diffrent types of security or no security, no luck.
Guys, maybe i wrote it wrong, but this MacBook can't see ANY network. Around me there are 4-6 other networks which I'm able to see from other machines. So *problem is, this Macbook can't seen ANY network - not just mine.* BUT when i'm with this Macbook in office for example, or any other location, Wifi works....
And one more important thing, this happened suddenly. I was able few months ago to find any WiFi around me with this Macbook. No changes to router, no changes to mac. Problem is somwhere in the middle...try to focus on this: why i'm not able to see any of those cca 6 networks around me. I really think it has to do something with distorted signal and Wifi card used in new macbooks. It's really sick, because all other machines works perfectly (MB 07, MBP 06, PC, iPhone 3g)
I found a log on the router, and it's happening all the time:

My new macbook pro can't find my Belkin network

My new Macbook Pro is recognizing all sorts of newtorks in the area except the one in my home. I have a Belkin N+ wireless router which I know is working because two other computers (pc) and my wife's iPad are having no problems connecting. This is a frustrating start for a hesitant pc-->mac transition. Any help will be greatly appreciated.
Jim

Just finished trying the suggestion from my Mac store "genius", and it WORKED. He suggested that I connect to the router directly with ethernet. His thought being that once my MBP found the IP address it would be able to find the network wirelessly. While still connected I went to System Preferences/Network, selected WI-Fi and entered the network info (name & password). There it was - connected.
Don't know how to make this solution available to everyone with the same problem. If someone knows how, go for it.
Thanks to everyone who responded. Your efforts are appreciated.

My 13in Macbook Pro can't see a wireless network but my friends Macbook Pro can

Me and my friend both have identical 13 in Macbook Pro's except he has 250 gb and I have 350gb. Everything else is the same even the wireless card. The problem is, he can see and connect to a unsecured wireless network but i can't. Why is this ?
Our computers can see the same networks on the list but my Macbook does not see one network, the unsecured network !!!

I never said there wasn't an issue, just that blame could not be assigned based on what we know now and that there are many more people not having problems with Leopard and WiFi than those that are.
In my circle of associates I know of literally hundreds of Mac owners, of which approximately three are having WiFi issues.
I know how frustrating it is to be one of those afflicted - my stories of constant WiFi drops for the first six months I owned my MBP have been recounted in several threads.
But it's just as frustrating to read how Leopard is just plain broken when in fact I've not seen a single WiFi drop in Tiger or Leopard since February 2007.
This is also why I've continually urged people experiencing the problem to open an AppleCare case - it's only then that Apple Engineering can find the commonalities in cases where WiFi is failing and either fix their driver or notify the router manufacturer of their bug.
Are there bugs with AirPort in Leopard? Of course, and I even know of one that affects me on occasion that's known, and that's a failure to reassociate with a known network when waking from sleep. The workaround is simple - toggle AirPort off and back on - but it's a known issue nevertheless.
But each of these threads addresses an individual problem, and among the numbers of people experiencing difficulties, few report that their Mac sees no wireless networks, and that's what the advice I've given in this thread is geared towards.

Ipad2 can't find home wireless network

Hi there.
I'm getting reeeeeeeeeeeeeeally frustrated. My ipad2 had no problem finding my home network when I first bought it but I've recently had a problem with my talktalk phone line (it was down over the weekend) and now my ipad can't find my network! My desktop pc is connected and I can connect to the internet no problem. I'm using a Huawei Echolife HG520b wireless router. Even after following talktalk's instructions on-line I've not been able to find my user name/password to try and connect manually.
Can anyone help??
Singlikenooneislistening x

Sing-
Unplug your WiFi router for a few seconds. Then reset the iPad's network. Go to Settings-General-Reset-Reset Network Settings. You will need to reconnect the iPad to WiFi. I'm not sure how you would reset the Kindle, but unplugging the WiFi may solve the problem for it as well.
If the problem continues, see <Troubleshooting WiFi Networks and Connections>.

MacBook pro can't find any wifi networks. HELP PLEASE

Ok so my late 2011 MacBook pro15" starTed dropping out of my network every now and then. Rebooting it got it hooked back up again. Now just a few weeks ago its not picking up any real wifi networks (according to my phone and what my computer showed me before there's a bunch in range). It shows this network called setup as the only wifi network in range and when I click on it, there is this little grey picture of a computer where the wifi bars should be.
Xbox, phone and all of the roommates devices are hooked up just fine.
I've taken it out to a couple of coffee shops and its the same thing. Either seeing no networks or that setup thing.
I've tried restarting, verify and repair disk, deleting all of my preferred networks. I don't know what else to do.

Also I've tried to use one of those usb WiFi adapters that essentially bypasses the computers airport card. That shows all the networks in range but will fail to connect to any of them.

Macbook Pro can't find my home wifi

I just got my battery replaced.. All my data disappeared. The worst thing is, I can't find my home wifi network but my neighbour wifi network is available. Pls help me fix this.
Mine is a MBP 2011.
Your help is much appreciated!

Hello, Sallyelainelee!
You may want to check the settings on your Router to make sure there isn't something in its configuration that's preventing the MacBook Pro from seeing it. If the MacBook Pro can connect to other WiFi networks OK, I would imagine that this would be the case.

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

Macbook Pro can't find Wifi after closing

I moved house and got a new wifi provider. My Macbook Pro can't find it sometimes after I close my Macbook which forces me to restart for it to join the network automatically. SOMETIMES I get a popup window with networks that it picks up and SOMETIMES my network is listed and I can select that, but not all the time. Why cant my Macbook find my network sometimes? It can find everybody elses except mine!

My macbook pro can't "find" my disc (?!)

I've just got the sims 3 island paradise and I've inserted the disc my macbook pro can't "find it". It asks me to insert the disc for me to be able to play when it's already in!? Why? Please help!!

Call AppleCare (1-1800-APL-CARE) and give then the serial number. They will send you a new copy of the two disks for shippingand handling of $16 each (I think $16 each).

Can't find *some* wireless networks

Hi
Have seen vaguely similar posts but couldn't quite follow. I've used my G4 powerbook to connect to a whole range of wireless networks using Airport and have never had a problem. However I was trying to connect to a wireless network at my local pub and couldn't do it. Airport couldn't find it, when I manually entered all relevant info (including password), it still wouldn't connect. Other laptop users, including others with Apples, don't seem to have a problem and they can't get my laptop to co-operate either. It can still find other wireless networks elsewhere with no trouble. Any suggestions as to what I'm doing wrong?
Thanks
Powerbook G4 Mac OS X (10.3.9)

Have the other apple users connected to the "hotspot" in the past? If so, their mac's may "remember" the settings of the network.
The network hotspot, as a security measure, may not broadcast the SSID and you may need to enter it manually, provided the hotspot "posts" it or gives it to your when you make a purchase. (I've seen a number of hot spots either post it near the register of give it to you after making a purchase to prevent users just accessing it without being a consumer of their products)
The hotspot may also encrypt the network, which they will usually provide as well.
I hope this helps!
P.S. There are several "Widgets" available for download that will identify if a network is available, but may not be broadcasting their SSID, this will help confirm that you are getting the signal, but just not the details in order to log in, one can be found here: http://www.apple.com/downloads/dashboard/networking_security/airtrafficcontrol.h tml
