Airport shows full bars but no networks listed, not connected

I recently began having an issue where my MacBook Pro (mid-2012, running 10.9.2) loses the wireless connection. However, the Airport icon in the menu bar still shows full bars (as if I were connected), but no networks are listed in the drop down menu.
Our other computer (a 2008 MacBook) and phones (moto G and Nexus 5) remain connected, at the same time, nor have they any similar issue. So it appears to be an issue specific to my MacBook Pro.
When I try to turn the Wi-Fi off then back on in the menu bar to see if it will reconnect, the Airport icon goes empty when I click off, but it does not come back to show the bars when I click it back on, remaining 'empty'. Yet I in the drop-down menu I regain the option to 'Turn Wi-Fi Off,' though no networks are listed.
Also, I use this machine daily at work on a university network Wi-Fi and have not had any issues (yet).
I've run Disk Utility after running into this problem, and it instructs me to Repair the Disk in Recovery Mode (via restarting the computer with CMD+R). Doing this, and sometimes doing just a normal restart, so far brings the connection back as normal.
This happened for the first time last weekend, happened again a couple days later, then twice this morning. So it's not constant but is enough that I'm seeking help.
I've scoured the system.log but don't really know what I'm looking for, thus not sure what to paste in here that would be helpful.
Thanks.

Unfortunately, I'm living in a spot in Europe that's not really near any Apple stores (and not sure I wholly trust the nearest 'Trusted retailer' to sort this out).
The more I dig through this issue, the more it's seeming to categorize with the numerous discussions already ongoing about wi-fi drops with Mavericks (here, here, and here for example). The jist of these is that there seems to be no true, ultimate "fix." I tried many of the suggested workarounds (deleting Bluetooth plist, keeping the Bluetooth off, dropping the Wi-Fi from the Network preferences pane and re-adding it, creating a new network location, unsyncing iCloud Keychain, resetting the PRAM, rebooting the SMC). None gives permanent fix thus far.
My hardware tests and Disk Utility reports still come back clean, as well.
And I'm again using this computer on a Wi-Fi network at work with zero problems so far.
Further, we still have another computer (older MacBook, running 10.6.8) and two phones connecting to the home Wi-Fi that haven't had any issues, so it's not likely as simple as a bad router or home connection.
Whether something in the configuration isn't playing nice with Mavericks, however, is an issue I'm going to try to sort out further (e.g., I've read that changing the wireless router channel has helped some people).

Airport network connected on full bars but "no internet connection" and missing lock icon!

this is really frustrating!
I'm using wireless in my house. when i click on my network it connects and it shows perfect connection which is full bars.
on Network Preferences it says that i'm connected to the Airport but when i go to Safari it shows "You are not connected to the Internet" so i click on Network Diagnostic where the 3 network status on top has the green indicator but the ISP, Internet and Server show red and failed.
I don't think there's anything wrong with my internet connection since I'm able to go online using my sister's computer and also on my iPhone.
There's also usually a Lock icon/symbol next to my network's name but when i'm connected to my network the Lock icon seems to be missing but it still shows full bars connection. I really don't get how it's possible to be connected to a network, but no internet connection, while i can access the internet on other devices.
Please help me out here. I've tried ways like going to library>preferences then put the system configuration into Trash, and going to Network Preferences and removing the Airport service and creating a new one.
and one more thing. all mentioned above are when i clicked on Advanced on network preferences then i clicked on TCP/IP and changed the Configure IPv4 from Using DHCP to Manually. When i'm back to using DHCP there's an exclamation point over the airport icon on the top bar and it says no internet connection.

Got my own question answered by a colleague.
He had me create another "Location" in the network pane of System Preferences, then choose it and click Apply. I created a new location which I called 'Airport', chose it and clicked Apply and sure enough, an IP address showed up and all is well.
Justin said it's a network bug in Leopard.

How do i restore my wifi setting back to the factory settings? I have changed it somehow :/ and now my wifi will not connect. My Airport is on and showing full strength but will not connect.

Ok, if other devices are connecting but just not your MacBook then let's start troubleshooting the MacBook to possibly find out why.
Please try each of the following, in order, until hopefully resolved:
Note the following are excerpts from an OS X Daily article.
* Turn Airport on & off – You can do this via the Airport menu bar or from the Network Preferences. This is the first thing you should try when troubleshooting Mac wireless problems.
* Make sure Wireless/Airport card software & firmware is up to date – This is usually done just by going to the Software Update menu, if there are any updates available for your Mac or Airport, install them.
* Delete and recreate connection – Try deleting and recreating/reestablishing the wireless connection, sometimes a setting can be corrupted and this may fix it.
* Create a new Network Location – Similar to the above suggestion, try creating a new and different wireless network location to see if it resolves the connection problems.
* Change DHCP auto settings to manual – sometimes there is a problem with the DHCP server, and if you manually set an IP address on the network you can be fine. Remember to set the IP to a high number so it wouldn’t interfere with other DHCP machines. As long as you have the subnet mask, router, and DNS settings configured manually as well, this shouldn’t be a problem.
* Flush the DNS cache – Launch the Terminal and enter the following command onto one full line within the Terminal: dscacheutil -flushcache
* Zap the PRAM – Reboot your Mac and hold Command+Option+P+R during restart until you hear another chime, let the Mac boot as usual.
* Delete Wireless Config files – Delete com.apple.internetconfigpriv.plist and com.apple.internetconfig.plist files from ~/Library/Preferences and reboot
* Trash your home directories SystemConfiguration – Remove all files within ~/Library/Preferences/SystemConfiguration/ and then reboot your Mac.
* Reset your Mac’s System Management Controller (SMC) – For MacBook and MacBook Pro’s: Shutdown the MacBook/Pro, remove the battery, disconnect the power, hold the Power Key for 15 seconds. Replace the battery, reconnect power, and zap the PRAM and wait for 2 chimes before letting the keys go. Let boot as usual.

I have an old PowerPC and a Macbook Pro running 10.6.7 sitting side by side. Both are using AirPort to connect to the internet wirelessly to the same router, but the old Mac connects with full bars, but the MBP struggles with only 2. Pls help, thanks!

Yes, I could connect them by ethernet if all I wanted to do was transfer files, but I would like to network them so I could use wireless internet. The machines are not always so close together, I did that to simplify the testing. With the very slow transfer speeds I am reluctant to move ahead with the internet step.

Shows full bars and connectvity in wifi but when hen saysim not connected

I turn on my wifi at a hotspot at d mall and it connects to a network and shows full bars and connectivity but whenev I try to open safari or my email it says im not connnected to d internet... ??? ummm no clue! a lil help plis!!

Some hotspots require additional authentication (you have to open Safari and click an Agree to Terms button, etc.). Others are 'open' networks, but require use proxy server which restricts access. If it works at home but not at the mall, the issue is with that network - you could try asking whoever's network it is.

Airport Extreme, Full Bars No Connect?

Please forgive me if this has been answered, but I can't find it. I recently moved and changed service providers from Bellsouth DSL to Cable. I've tried reconfiguring my Base Station with no success. I have 2 lap tops and a Iphone ...They all show my network and full bars, but none will connect? I would like to have internet connected directly to my tower, then out of my tower to the base station. I'm pretty sure this worked for me prior to the move (Basically I don't want my tower to connect wirlessly). I'm not sure what I need to do. Please help.

First configure your network as I described in my last reply.
Then setup your AEBS as follows...
AirPort Extreme Base Station Setup (AEBS) w/High-Speed Cable Modem
Perform a "hard" reset of the AEBS
o (ref: http://docs.info.apple.com/article.html?artnum=107451)
Modem/Router Power ReCycling
o Power-off the Cable modem, AEBS, & computer(s); Wait for at least 30 minutes.
o Power-on the Cable modem; Wait at least 15 minutes.
o Power-on the AEBS; Wait at least 5 minutes.
o Power-on the computer(s)
Setup the AEBS
Either connect to the AEBS's wireless network or temporarily connect your computer directly (using an Ethernet cable) to the LAN port of the AEBS, and then, using the AirPort Admin Utility, try these settings:
AirPort tab
o Base Station Name: <whatever you wish or use the default>
o AirPort Network Name: <whatever you wish or use the default>
o Create a closed network (unchecked)
o Wireless Security: Not enabled
o Channel: Automatic
o Mode: 802.11b/g Compatible
Internet tab
o Connect Using: Ethernet
o Configure: Using DHCP
o WAN Ethernet Port: Automatic
Network tab
o Distribute IP addresses (checked)
o Share a single IP address (using DHCP & NAT) (enabled)
Once you verified that you can get Internet access for all of your computers, you should secure your wireless network. To do so, I suggest that you make these changes:
Change Wireless Security
o Wireless Security: WPA2 Personal
Base Station Options - WAN Ethernet Port
o Enable SNMP Access (unchecked)
o Enable Remote Configuration (unchecked)
o Enable Remote Printer Access (unchecked)

As with previous posts this is usually a DHCP issue and occurs frequently especially with routers connected to Cable Modems or those Micro-Cell towers.
Unplug all Routers, AirPorts (or other off brand Wi-Fi broadcast units) and any other Wireless broadcast unit that might provide you with a WDS (often other AirPorts feeding off the signal of the AirPort closest to Cable/DSL Modem) and best to totally power down the Unit affected; lastly either hold a reset button on Cable/DSL modem for 30-45 seconds or actually power it down if an option (not suppose to power down Cable Modems that have Telephony for some odd never completely explained to me reason).
Let Cable/DSL Modem re-boot till 'all green lights'. Then power up each device involved in order from closest to farthest waiting each time for completion of initiation. Micro-cell towers can take 10 minutes to completely re-boot and you must wait for across the board green lights in my experience. Even WDS can add a few minutes till all green on mother AirPort unit.
Only NOW may you re-start the offending device and see if it will connect. Works about 99% of the time!

I would select a link from the drop down on the address bar but the page would not open. I would select it again but the page does not open. I could only reach website by selecting google on most visited list.

After updating AVG anti-virus, I encountered a problem on Firefox. I would select a link from the drop down on the address bar but the page would not open after clicking on it. I would select it again, even double click, but the page does not open. I could only reach website by selecting google or yahoo from my dropdown on the most visited list and then click the website that I want to visit. I would like to do this in one step by just selecting a link from my history on the address bar and select a link instead of going to google and then writing the page I want to visit. What could be the problem? When going to the address bar to select a link to open, why does the site not open? Any help would be appreciated.

Hello there ypda75,
I have an article here that has a list of settings to get from your Email provider so you can make sure that the settings are correct. It has troubleshooting steps to try as well. Also I would recommend restarting the router, and/or testing a differnet network.
iOS: Unable to send or receive email
http://support.apple.com/kb/ts3899.
If you are unable to send or receive email, try the following steps:
Restart the iOS device.
Tap Safari and attempt to load a webpage to ensure that the device has Internet access. If you're unable to load a webpage, try the Wi-Fi assistant.
Try an alternative Internet connection.
If your email is provided by your Internet provider, try connecting from the home network.
If your iOS device has an active cellular data plan, try to disable Wi-Fi: Tap Settings > Wi-Fi and turn off Wi-Fi.
If not, try a different Wi-Fi network.
Log in to your email provider's website to ensure that the account is active and the password is correct.
Delete the account from Settings > Mail, Contacts, Calendars and then add the email account again on the iOS device.
If you're still unable to send or receive email, contact your email provider and verify the account settings are correct. You will need to gather this information (PDF).
All the very best,
Sterling

I'm afraid you'll have to get the phone serviced, dropping the phone must have damaged additional parts inside the phone.
But Apple will not service the phone anymore, opening the phone and replacing the battery should only be done by authorized personal, not by users.
You'll have to look for a 3rd party repair shop and see if they can fix this, sorry.

My wireless internet is working with all of my other devices but my imac will not connect to the network?

Can anyone help? My wireless connection is working on both my iphone4S and my ipad2, but my Imac will not connect to the network.

First run Software Update to make sure your iMac is up-to-date.
Even though things are working OK on other devices there may still be issues with your modem or router so it's best to start there. Locate the manuals on both devices and reset each. Do the modem first then the router. Next make sure the router has up-to-date firmware. If the problem continues after updating resetting and updating both devices then download and install iStumbler and let it run for about 30 minutes. iStumbler will scan your area for the Wi-Fi networks being used, pay attention to the channels each network is set to. Most routers are pre-set to channels 5 or 6 and if you are in a congested area and all the routers are set for channel 5 or 6 then you can see where there might be a problem. Set your router's channel to one not being used in your area, you have at least 14 channels to choose from. Also check to see if your router is using 802.11n, if it's not then it would be wise to upgrade the router to a faster device.
Next is if you are still having issues the problem could be your ISP's DNS settings. If you want to learn about DNS please read CNET's DNS Article and MacWorld's DNS Troubleshooting . Then use the instructions below to reset the DNS settings:
1. System preferences
2. Network
3. Click Advanced
4. Click DNS tab
5. Click + sign
6. Add 208.67.222.222
7. Click + sign
8. Add 208.67.220.220
9. Click OK.
10. Exit System Preferences

Do other devices successfully connect to the router?
Does the iPod successfully connect to other networks/routers?
Does the iPod show wifi bands in the upper left?
Try:
- Resetting the iPod:
Reset iPod touch: Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.
- Powering off and then back on the router
- Resetting networksettings: Settings>General>Reset>Reet Network Setting

If you are the only user on your computer you probably don't have multiple user accounts set up and can disregard that. If you are using iTunes 11 go to View>Show Sidebar. Now see if your iPad appears under Devices on the left side when you connect it. If it does, click on the name of your iPad on the left side and your iTunes sync settings options will appear in folders with tabbed headings to the right.
If it doesn't appear on the left side, follow the troubleshooting steps shown in this article: http://support.apple.com/kb/TS1538.
