Macbook no wifi?

HI, my macbook started by having a perfect WIFI signal , then it would work but then cut out. Now the WIFI doesnt seem to recognize any signals. I have begun to always be plugged directly into the router for the time.
I have tried most of the obvious things suggested on the internet...BUT STILL NO WIFI! I reset, rebooted, renewed the DHCP lease.
ANYONE HAVE ANY SUGGESTIONS! Many Thanks!

Hi, benjamineinstein.
Thank you for visiting Apple Support Communities.
Here is an article I would recommend going through when experiencing issues connecting to Wi-Fi. I would also make sure all firmware updates have been processed on the router.

Mid-2012 MacBook Air WiFi Reconnect-Partial Solution

The MacBook Air seems to have some significant WiFi issues for a lot of users. My issue is as follows: the MacBook will connect to any compatible WiFi hot-spot with no problems, and it will maintain the connection almost always. The problems come when I try to reconnect to the internet over the same WiFi hot-spot after waking up the MacBook. Even more frustratingly, the problem is not consistent. Sometimes it works, and sometimes it doesn't. After some investigation, I have come to the conclusion that reconnection problems happen when:
You wake the computer up from computer sleep (not display sleep or Power Nap)
You are using a specific cable modem (the one I tested on was a Motorola SURFboard SBG6580 DOCSIS 3.0)
You have not restarted your cable modem while your MacBook was asleep
The MacBook Air will connect to the WiFi network (i.e., it can access other devices in the wireless LAN) when woken from computer sleep; it just will not connect to the internet
The only way to get the connection back is to restart the cable modem. Restarting the MacBook, restarting your WiFi base station (in my case a brand new AirPort Time Capsule tower), having the MacBook forget the WiFi network and then reconnect--all do not work. But if I just restart the cable modem, the MacBook connects with no problems. This is a problem specific to the MacBook Air because none of my other devices ever have a problem connecting to the network after waking up from sleep (including a Lenovo ThinkPad E530c). As has been proposed in some of the many discussions about MacBook Air WiFi issues, I think it has to do with the bleeding-edge power saving modes that the MacBook Air enters in to when it goes to sleep. Apparently, the computer sleep mode will cause it to not be able to reconnect to the internet, so it seems to be some sort of incompatibility or bug between the MacBook Air and the cable modem--in my case, the Motorola SURFboard.
So that's the problem, but I do have a partial solution while the engineers figure out a fix. Set the System Prefs > Energy Saver setting on the MacBook to never go into computer sleep (I set it only for Power Adapter, not Battery). In my case, this is a workable solution because I have my MacBook Air plugged in at home almost all the time. I have lived with these settings for a couple of days now and whenever I wake up my computer, it still has the internet connection and works as expected. And if for some reason I don't plug it in and it goes into computer sleep, I don't waste time troubleshooting. I just restart the cable modem and after a minute or so, the internet connection is re-established. I'd be curious to know how many cable modems this happens with, and if anyone has a fix having to do with cable modem settings (the Motorola SURFboard, to my knowledge, doesn't have a web app interface to tweak settings, perhaps because my cable company doesn't want me tweaking things, but I frankly have not spent any time researching that end of things).
Hopefully this will help some MacBook Air owners (is this an issue with MacBook Pros?) that have this problem.
Good luck!

Have the same problem. Was OK for nearly two years then started two days ago.

is there anything else I can try first?

If the technician at the shop is competent, he has given you a diagnosis that should have identified the problem. You could run the Apple Hardware Test to verify the findings:
https://support.apple.com/en-us/HT201257
Note the Apple Hardware Test is not definitive.
Go to the iFixit.com and Powerbookmedic.com web sites. They have parts and installation instructions. To install an Airport card is fairly easy.

I have a Macbook, my wife just purchased an Ipad2, Home network

I have a macbook, my wife just got the ipad2 today. She joined our home network. I thought that because these are both apple products I would be able to see the ipad in the finder viewer?
I have a cisco home router, not an apple router. Should I not be able to see the ipad ????

I can't see my iPhone 4 in the Finder viewer when connected to my wifi network. I don't think the iOS devices will show up, as you can't copy stuff from them wirelessly.

MacBook Air wifi internet shared network not working on tethered android phone GT B5122

MacBook Air wifi internet shared network not working on tethered android phone GT B5122
I have created a password protected wifi internet network on my Macbook air. I tethered by Andriod phone onto this network, but the internet connection works intermittently on the phone, and when it stops working the network continues to show as connected to the shared network mostly(other times it keeps renewing the wifi IP address on the Andriod phone).
Also the network the MBA is connected to, is a hardwired one using a SSH login account in a student accomadations.
I am not sure, but all the restarting and refreshing of system, phone and wifi sharing and re-enabling wifi is not reparing the internet connecting on the wifi network for the phone
Really puzzled, if this is one of the Apple, Andriod compatability issues.
Cheers,
Vivek

Hi.
I'm having trouble with the wireless connection on my new home hub 3. Most devices will connect easily, but there are three devices that have trouble connecting. These are an Android Phone (Samsung Galaxy Mini), an android tablet (Sony Tablet S) and an iPod. All of these devices work perfectly on other network connections, and other devices in the house are quite happy connecting to the network.
The Androids can see the network, and will try to connect to it, but when they do they just go through a loop of "connecting">>"acquiring IP address">>"disconnected". I have tried resetting the Home Hub with a pin, and that lets the devices connect for about 24 hours, but after that time they stop connecting again.
I'm really not sure what to do to fix the problem, so I will very much appreciate some help.
Many Thanks.
My lads SGMini connects perfectly to our hub3
Have you installed the BTFon app to these devices?
If so, you could delete it and then see what hapens.....

Strange macbook pro wifi problems - selective wifi disconnection

I have 3 macbook pros, two iphones and an apple TV. My primary macbook pro has some very unusual wifi problems that are hard to pin down. It frequently disconnects and reconnects itself to the internet constantly throughout the day. I've been testing it in various ways and today I noticed the strangest anomaly by far.
While working today, my primary macbook pro could not connect to the internet through any of the 3 browsers I use. Airport Utility said the internet was down (internet icon was amber, airport icon was green). However during this disconnection, my p2p application (Soulseek) experienced no disruption of service and continued to download files. I opened my second macbook pro and strangely enough, the 2nd mac was able to connect to the internet through browsers without issue, and the airport utility on the 2nd macbook pro said the internet was connected. My Apple TV was connected too as well as my iPhone.
It is often difficult for me to troubleshoot network problems because there are so many variables (ISP, airport assembly, airport base station, OSX, airport utility, modem) but I guess in this particular instance, it seems clear that the problem has something to do with my macbook pro.
My primary macbook has always had wifi problems (and honestly, my last macbook--the one that actually worked today!--had similar issues back when it was my primary laptop). Last week, my primary macbook pro had the topcase, display and logic board replaced by Apple. When it came back, it had the same wifi connectivity issues it always had. Often, a restart will be a very temporary fix, but not always.
I am at a complete loss for what could be causing these lapses in service. In fact, right now as I was trying to access these forums, I could not even get my primary macbook to open the Apple Support Site on any browser. Every other website would open, except Apple Support. I opened my 2nd laptop and it opened Apple Support just fine. After 15 minutes, my primary laptop finally opened up an Apple support page in Firefox.
It is really hard to diagnose the problem. I find that Airport Utility has been so pared down and streamlined to the point that it is worthless. It is basically a blank window with 2 application logos inside. It looks very simple and user friendly until it has a problem, and then it tells me to do something very technical without an explanation for the layman (such as assigning DNS servers or putting the airport in Bridge mode). I always follow Airport Utility's advice, but I still have odd problems. I am often confused as to whether I should use Airport Utility or the Network button in System Preferences. They have the same options, but they're arranged under tabs with different titles.
Anyway, does anyone recognize these macbook pro wifi connectivity problems? Constant wifi disconnection on one machine (while all others experience no connection problems) coupled with instances of selective disconnection (like browsers not connecting while p2p is able to connect or browser connecting to some sites but not all?)
Thanks for any help or guidance

Same exact issue here. It happened once when I updated to Mavericks 10.9.2. It just happened again last night and I can't seem to fix it.
I tried all sorts of things like deleting the SystemConfiguration folder, PRAM, SMC, DNS flush, etc. Nothing helped. As I recall, the last time it happened it mysteriously fixed itself after a day or two.
Very weird problem. I have been troubleshooting computers my whole life but this one is tough to figure out. Other machines in the house connect up just fine.

Is the New MacBook Air Wifi N Dual-Band or Single-Band?

Is the New MacBook Air Wifi N Dual-Band or Single-Band? I cannot find any official information regarding this.
I have a Dual-Band router up to 450+450 and I'd like to know if the Mac would make the most of what I have.
Another related question would be… if the MacBook's Wifi could take up to 450mbs or would it only reach up to 300mbs?
Thank you!

Thank you Captfred for the quick clarification. A related question (and this might be obvious, I'm not sure) would be if the MBA uses single or dual antenna? I am not sure if N technologies always use dual antenna by default? The reason why I'd like to understand this is because I do watch quite a bit of streaming video. I supposed streaming through a single antenna could clog the connection quite a bit if at the same time I'm browsing other websites or download something else at the same time? While having two antennas would ease the communication by sending a request through one antenna and receiving the response through the other?
Best,
M

Macbook Pro Wifi Issue

I incorrectly posted this in the wrong thread this morning.
I'm hopeful you might be able to help me diagnose a problem I'm having. I'll provide as much detail as possible.
I have a first generation MacBook Pro. As of this morning I was running 10.5.6 and up until this week was using a linksys router and a comcast cable modem.
I used to have a great wifi signal throughout the house (always full strength), and around 12-18 months ago noticed the signal would weaken. The best I would get would be minus the top bar on the signal, and usually only if I was directly above or next to the room with the router. There were no new phones or devices added that might adjust the signal. On the other side of the house, I would have no signal at all.
My wife has a nine year old ibook and has no issues connecting through wifi.
When I bring my laptop to her parents' house or to the Apple store, where they use Belkin on N or Airport Extreme, I get a full signal.
I've recently suffered a hard drive failure and had a replacement drive installed. The problem persists despite the software update.
Not knowing if it was a router issue or an airport card issue or a combination thereof, I went to the Genius Bar. The genius recommended I upgrade my router to Airport Extreme, and if that doesn't work to return it and he'd focus on the airport card or antenna. I could get the flat rate repair (no AppleCare at this point) for $320+ to repair the problem if Extreme didn't work.
I installed the Airport Extreme router and got a full signal in the basement, far side of the house, upstairs - everywhere. Until around 10pm. The signal died from the basement. If I walked into the room with the Airport Extreme router, I'd get a full signal. If I left the room, I'd get a partial signal. If I walked any distance (10-12 feet), the signal would die. I restarted both the modem and router with no change. I reinstalled the linksys router and got a depreciated connection. I restarted the Airport Extreme again and got a full signal throughout the night, morning, through restarts, and when I returned home from work.
Last evening after using youtube extensively it died again. Linksys would barely work if I switched back, and no matter how many times I restarted I couldn't get the signal to last outside of the area of the router. I left it in the basement overnight shut down, restarted this morning, and had a full signal.
I'm looking for any potential guesses as to what may be causing the problem. I don't want to replace the card if it's the antenna or sink too much cash into a machine if it's a heat related issue linked to Generation 1 syndrome.
During all of this the ten year old ibook works fine. I know a lot of macbook pros have issues with their wireless and don't want to sink in the cash if it's more complex than that. Any advice is much appreciated!

Hi nashie1002,
If you are having issues connecting to your WPA2 WiFi network after a recent update, you may find the troubleshooting steps and settings in the following articles helpful:

My Mid 2010 MacBook Pro wifi keeps disconnecting, and doesn't turn back on. Help.

*Mountain Lion 10.8.2*
Here's what's happening:
I'll be browsing the internet probably surfing reddit (because what else do college kids do right?) and I'll click one of the links I'm interested in:
The page won't load at all, as if I have NO internet connection.
Click the wifi icon in the status bar. Before several networks (not just my current network) would show up. Now ONLY the network I'm currently connected to shows up.
Turn off the wifi to try to "refresh" it.
Turn Wifi back on. Now it will say "Searching for network" and show that I'm connected to a network, but the bars never fill the status bar icon. If I go to System Preferences > Network and try to turn on the wifi there it lets me click the button, but nothing happens.
Get frustrated that the wifi WILL NOT TURN BACK ON and restart computer
Start browsing the internet again or doing whatever college students do on the internet until it disconnects again.
See 1
What I've done to try to aleviate this:
Made a genius bar apointment. I'm out of warrenty, but he did confirm for me that my wifi card is working as expected, and it's not a hardware issue, but more than probable a software issue. He did some cool trick where he went to Library>Preferences>System Configurations and deleted the entire contents (I think this is where the network information is stored according to some of the plists I looked through) then restarted the machine and everything seemed to work ok for a while, but the problem came back. I actually still do this sometimes when it happens but results seem to be the same every time (Plus I have to re enter network information when I do this).
Genius bar guy suggested that I try reinstalling Mountain Lion. Didn't want to get rid of my data, so I just did an install over my current build. This took some time, but it seemed to work for a while, but alas the problem came back.
Genius bar guy suggested (as a last resort) a fresh install. So That's what I did. I backed up my computer (Really I just coppied my documents folder and music folder to an external. I did not use a time machine back up because "ain't nobody got time for dat") and I then formatted my hard drive (Which is an SSD if that may have anything to do with anything), and installed mountain lion again. For a while things seemed good, but the problem came back.
For clarification:
It has happened on multiple networks, not just the same network.
On top of that, every time it happens I have other devices connected to the same network and they work fine.
It has not always happened, this recently started about 2 weeks ago.
I have not recently installed any software that could have possibley done this (I use mostly MAS store stuff with the exception of Bartender, TotalFinder, and xQuarts, but all 3 of those had long been installed before I had to format my machine)
I can't really force the problem, but it seems to happen sometimes after the machine falls asleep, but I know for a fact it's also happened mid use (as described above)
Can anyone give me any kind of clue as to what is happening, why, and how I can fix it?

Years of fine internet use via WIFI then randomly it starts dropping then one day (weeks later) it is no longer accessible at all and even saying "No hardware installed" when I click on WIFI icon at the top right on screen. Here is how I finally fixed it!:
For six months I wallowed in this problem and had to connect my macbook pro to the internet via ethernet cable which as you can image was very restrictive :/
I have had numerous laptop technicans befuddled by this WIFI problem and most concluding with how my WIFI card must be broken and that I will need to buy a new one. The last suggestion I had on the matter was to buy a USB wifi dongle.
So I ended up buying this one, http://www.asus.com/nz/Networking/USBN10_NANO/Unfortunately my macbook pro didn't want to read the install disc and it didn't autorun so it didn't work. After reading more forums I saw that you could download the program from the net and sure enough it worked.. BUT STRANGER when I took the USB dongle out the WIFI was still working!! The program appears to have reminded my four year old macbook pro that it is indeed WIFI capable.
So to find this miraculous program its located herehttp://www.asus.com/nz/Networking/USBN10_NANO/HelpDesk_Download/
Same link as above just under SUPPORT>Driver&Tools
You then click on a file when its downloaded and a file called MAC will appear, then click on install. Within 5 minutes you should have your WIFI back. My macbook pro crashed again today but without having to get the shortest ethernet cable you've ever seen out again - I was able to install the program again and WIFI was up and running once more. Moral of the story - didn't need to spend any money to fix this and not even using the USB dongle.
So happy!! Hope it works for you too!
This also worked on a MacBook that lost its WIFI when a user accounts password was changed and the keychain password wasn't known to them - another random way to lose WIFI apparently

Macbook Air wifi issue

I have a problem with my macbook air. I can find easily my home network, and it usually works ok at the begining, but after some time, 5-10 minutes, it started to works very slow, or just stop responding at all. Than I cant open any page, cant download mail, or anything. Sometime if I move my macbook air to another location it starts to work again for some time, but sometimes that doesn't help either. Sometime it helps to turn wifi off, than on again, but that also works for some time, and than again it blocks. I had mac os x lion, and now I have mountain lion, and same problem occurs. I even reinstall mountain lion, because I thought maybe it's the software issue, but it happening again. Today I changed my router, because before I had one with only B\G, and now I took one with N standard, because I thought this happening because of old router, but it happened today again.
Could this be a hardware issue? Should I bring it to apple store, and what can I expect? Would they give me another one if this is hardware issue, or I would get refurbished one, or they will try to repair this one? I don't know what to do.

With the help of Apple Support this problem seems to be cured.
Here is a summary of the steps that they took me through:-
In Settings>Network>
Click on Gear Wheel beside +- at bottom of list of network services, select "Set Service Order" and check that WiFi is at the top of the list.
Click on Advanced and select DNS tab. Click on + at bottom of DNS Servers List and enter 8.8.8.8
In WiFi tab check that your preferred network is at the top of the list.
Apply any changes that have been made and switch off.
Reset SMC and NVRAM/PRAM
Check that there are no channel conflicts with other wifi networks.

Safari of my Macbook (on WiFi) suddenly fails to connect to the Internet. A popup window message says another device on the network is using my computer's IP address.

But then there was still no Internet access even after I have disconnected all other home computers (a total of four including the Macbook and one iMac desktop. For simplicity, I shall categorically called them Mac hereafter unless otherwise specified. The Macs are operating on WiFi.).
The window message recommends changing the IP of either the Macs or the other device. The latter of course does not apply because I don't think the other device is one of my computers.
My questions:
(1) Why did that happen suddenly since the Mac and other computers on the WiFi was working fine in the morning (as well as days before) and then all of a sudden an unknown device is using my computer's IP? As far as I (we) can remember, we did not do any thing unusual this morning nor had we downloaded any special programs.
(2) How do I change the IP since it requires Internet acess to do it and since I can't access the Internet on the Mac?
(3) I am almost sure the problem is not caused by the Internet service because when I connected the Ethernet cable from the DSL modem to an old Windows PC, I got Internet via Internet Explorer. [I am actually sending out this message via IE on my PC.] However, when I cennected the Ethernet line from the modem to a WiFi router (Airport Extreme) and then connect the router and the old PC, I did not get Internet on either the Mac nor the PC. Similarly, there was no Internet on both Mac and PC If I connect Ethernet only between the modem and the router but not between PC and router. So, the question is whether a third unknown party has gotten hold of my Mac IP address and is trying to break into the Mac? Can it steal my personal info?
(4) How can I repair the Mac now and prevent future recurrences? Is changing the IP address the way to do it? (But like I said before I had tried but could not change the IP because I did not have Internet access on the Mac. Is there an alternative method?)
(5) I wonder if a computer's IP address remains constant if you don't change it. The reason I am asking this question is because the aforesaid window message on the Macbook--not sure about the iMac--shows a different IP address--a few numerical digits were changed--almost every time it pops up following every failure trial of mine to access the Internet. Was the Macbook trying to change the IP for me or was there some thing not right?

Re: Another device on the network is using your computer's IP address.
This message/problem was occuring intermittently for me in a household with two MacBooks accessing one Airport extreme. Rebooting the modem and router would only temporarily fix the issue for me, so I spoke with a friend who works for Apple and it seems that the Airport Extreme settings were at the root of our particular issue.
The router(Airport Extreme) recieves only one IP address from the modem and in order to allow it to share the IP address with two computers at once, the solution in my case was through:
Applications>Utilities>Airport Utility>Manual Setup>Internet
under Internet Connection- Select "share a public IP address"
under NAT, check the box for "enable NAT Port Mapping Protocol"
(this will allow the sharing of one public IP address with multiple devices)
if this is a new setting, then click "Update" and the Airport Extreme should reboot itself with new settings applied.
When all else is working properly, this is a satisfactory solution in my case.

Macbook Pro - WiFi turns OFF and won't turn back ON

Hello,
this is my first time posting something on this forum; I will be as detailed as possible. I bought a Macbook Pro back in 2011 and It came with Lion OS. Last year I upgraded it to Mavericks and so far it has been a nice experience. However, in the past week I have experienced a very strange and irrating problem with my macbook. While doing work all of the sudden the WiFi would turn off and lose all connection to the web. I attempted to turn it back ON by clicking on the wifi signal icon but something weird occured, it was still 'ON' according to my mac and the only option available was to actually turn it OFF, so i clicked on it and the icon would go empty with no curvy lines (i attached a picture). Then i clicked again on the icon to turn it back on, however, as was doomed to remain in this state cause no matter what I tried.. the wifi will remain off even after clicking on the 'turn wifi on' option multiple times. I tried going to the assist me option under network preferences and I obtained multiple results with no fix. I tried sending my mac to sleep though at first seemed to fix the problem.. the wifi inmediately went back to being off and wont catch a signal. The only thing that fixes this is a fresh restart which is annoying and unacceptable...this is really annoying and I need a solution asap because this problem is become very frequent (once every 2 hours)... any help will be appreciated it.
I attached 2 pictures and the console log when this happened.
1. A picture of my assist me window before i sent it to sleep, shows the WiFi on the left with the 'Failed' (which confuses me). it also shows the wifi icon empty ( like it was off) but the computer shows as if it was on and would ask you to turn it off... weird?
A second picture after I sent my mac to sleep. Though it seems like there was no wifi signal available, the router was on and literally next to my mac...but my machine wont catch up the signal. (other devices were connected to the wifi and have no problem with it).
Here is the console log right before and after my this problem occured:

Thank you for your detailed troubleshooting attempts. Very helpful. Sorry, I cannot read "logs." My eyes just glass over on those things. Hopefully, a knowledgeable user will come along shortly to decipher for you.
I noticed from the pics that your location setting is "untitled." Have you tried the "Automatic" setting? Run the diagnostic test? Results?
Try the basics first:
   Change your router channel number. Most times this works & is all you have to do.
Disconnect & reconnect your modem. unplug it for about 10 seconds. Plug it back in. Do the same for Apple’s routers. Wait for everything to reboot.
System Preferences>Network
Click the Assist Me button.
In the next window that pops up, click the Diagnostic button & do the necessary.

Macbook Pro WIFI connection slow and intermittent

I recently moved to a new apartment and had Time Warner install our internet/Wifi. My Macbook Pro will connect to the Wifi and work fine for about 30-60 seconds and then become extremely slow, even to the point of no connection most times. I have tried using both the new router and the old router that worked just fine at our old apartment but both behave the same way. I have reset the routers multiple times but that does not fix the situation and I do not believe the router is the problem since my two roommates (one of which uses a Macbook Pro) have no connection problem. My iPhone connects perfectly fine as well. When I am on other Wifi addresses, my Macbook works just fine. Also, my Macbook is only one month old. I called Apple to try and solve the problem and they believe it is an interference problem however the connection remains the same no matter how close or far from the router I am and all other devices don't seem to have interference problems. Any help is very much appreciated!

Might be corrupted network preferences ..
Type or copy paste the following:
/Library/Preferences/SystemConfiguration
Click Go then move all the files in the SystemConfiguration folder to the Trash.
See if that makes a difference.
Your Mac will generate a new SystemConfiguration folder for you.
If that doesn't help, try Wi-Fi diagnostics here > Wi-Fi: How to troubleshoot Wi-Fi connectivity

Macbook no wifi?
