No Safari communication, but connected at full strength

I have an Cisco EA4500 router. It has worked fine, but lately I have had a problem with communication to Apple products.
At times, when I try to use Safari to load a web page, the communication progress bar stalls and does not continue. No page is loaded and the device just stalls out with basically a blank screen.
The WiFi symbol is present and at full strength. I can get the communication back by clicking on the WiFi symbol, turning off WiFi and immediateley turning it on again. This is true for all the Apple devices. It does not happen every time or even a large number of times, but it could happen several times a day.
This seems to happen when I get the iPhone, iPad or either of the MacBooks out of sleep mode (I guess that having to put in my password in any of the products would qualify as coming out of sleep). I seem to be getting mail and I don't notice it in the mail or other applications.
I have a Macbook Pro, a Macbook Air, 2-iphones, 1-iPad, a Windows Vista Dell, a Windows Vista Gateway, a WiFi Brother Printer, a Nest thermostat and 3 or 4 other things on my router.
About the time I upgraded to iOS7 and Mavericks and purchased my iPad Mini, I started to have these internet communications problems with the Apple products. I don't seem to see any communication problem with any other thing connected to the router.
Does anyone have any ideas?

I've seen this many times with Cisco's WiFi implementation. The trick is to disable your AP's setting for "WiFi key rotation". I'm not sure how to go about this on non-Cisco APs since it tends to be one of the more esoteric settings available, and consumer-level APs typically don't allow meddling in such minutia.
Anyway, this isn't about your WPA passcode, but the broadcast key that the AP assigns internally to your associated devices' sessions. The CIsco APs, by default, will rotate the WiFi key based on time, and also when a new device associates to the AP. Mac OS/iOS, for some reason, ignore the first key rotation packet, don't pick up the new key, and therefore need to be re-associated as you described, usually by disabling and re-enabling the wireless NIC.
Search for "wpa2 wifi key rotation" for more info. IIRC, this only happens with WPA2 and AES. If you have the option to use WPA2 and TKIP, that should be a good workaround if this isn't a high-security network.

On a Cisco AP, you configure it per-radio in Security -> Encryption Manager -> Global Properties

Internet Is Connected At Full Strength, But Nothing Works?

I got my Macbook Pro in August 2008, and other than having difficulty picking up wireless networks, haven't had any connectivity issues. I've been at home since May 8th, and the wireless here has been working fine--up until a few days ago. Airport says that I am connected at full strength, and diagnostics says that there is nothing wrong with the connection, but nothing can access the internet (safari, firefox, adium, itunes, or updaters). Firefox tells me that there is a network timeout. I have a Linksys router, but I don't think that is the issue as a) three other computers in the house, the xbox 360, and my brother's ipod touch can all access the internet fine; and b)internet from my neighbors or my local coffee shop also don't work. I took it to my boyfriend's house, and it worked fine there where he has a mac network, but that could be a random happenstance as we only tried it once and my internet also started randomly working fine for a while last night. I'm trying to take it in to a genius bar before I leave for school in a week (as there isn't one close to where I'm going), but until then, anyone got any pointers? I've restarted Airport, the computer, the router, and the modem already. Thank you!

If you have some warranty left, and I assume you do, then why not call AppleCare first. Then, you'd have two more or less immediate shots at getting a fix. For lack of anything better to do, you could do the things mentioned in this thread: http://discussions.apple.com/thread.jspa?threadID=1924527.

My new ipod is extremely slow, but i have full strength wifi. Works fast at others homes.

My new ipod touch 4g is extremly slow in my house, but i have full strength wifi. Works fast at others homes. When i try to connect to the internet it gives me a server error. All other ipods and laptops work fine in the home. Does anybody else have this issue?

Have you tried powering off and then back on your router?
You can try:
- Reseting the iPod. Nothing will be lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
-Resetting network settings: Settings>General>Reset>Reset Network settings.

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.

Is anyone else having trouble setting up messages with the new mountain lion software? I keep getting a notification that i cant sign in and it is saying, check network connection and try again, but i have full wifi bars, thanks, Justin

Internet connected according to Network Diagnostic but Safari can't connect

I just bought a new iMac in Australia yesterday; when I brought it back home and connected the ethernet cable to it I thought it would automatically connect to the internet as my other family members' Macs have in their homes, and as my old PC did.
Unfortunately it did not, so I bumbled through Network Setup in System Preferences with little idea of what I was doing and essentially hoped for a miracle. I copied the 'IP address', 'Router' address and 'Subnet mask' numbers over manually from my PC but that didn't work. I then selected 'Using DHCP' and it gave me a seemingly normal IP starting with 192.xxx.xxx.xxx and the same subnet mask. When I run 'Network Diagnostics' it says my internet connection appears to be working correctly, and there's green lights next to everything. But when I go to Safari and type in www.google.com it takes forever before finally telling me that "Safari can't connect as the server is not responding'.
I have scrolled through pages of this forum trying to find answers but I haven't yet. I tried changing the DNS addresses to the ones from OpenDNS but that didn't seem to work.
Any suggestions would be greatly appreciated!

What kind of connection do you have?
-DHCP, this assigns the IP automaticly
-PPPoE, you will have to enter the information from your ISP manually in rder to connect
If you copy the IP from another machine it will create an issue since IP´s are unique to for machine.
Can you verify you internet connection, just to make sure it actually works?
+you can connect with other machines?
- you have to look at the settings on you machine
+you can ping www.google.com from Network utility
- if you can you have a connection to the internet, there might be a problem with your DNS server
+you can connect with IP addresses but not the HTTP
- copy and paste googles IP into your web browser, if it connects you should contact you ISP or look for DNS trojans in your system
+what does network utility show of send errors and link speed.

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.

I forgot to mention that, but I have done that as well.
An update: my husband took the iPad to McDonald's to see if he could connect there, and got the same message (Safari could not open the page because it is not connected to the Internet). I'm stumped!

Safari won't connect to internet but other browsers will

Firefox and Chrome can connect to the internet but since upgrading to Yosemite, Safari, iTunes and other Apple Apps have an exceedingly difficult time connecting to the internet. (ie server not found) I have to resort to turning off/on my wifi and/or restarting my computer. All other non-Apple applications can access the internet just fine.

I, too, am experiencing this problem. It occurs with both Safari and Firefox. It wasn't bad at the start; occasionally what seemed like my internet would cut out while I was surfing, but then the problem began to last for longer durations. As of this morning, I've been trying to get Safari to open for two hours with no success.
Here's the specifics. I open Safari. Most times, the load bar will extend about 1/6 the length and stop, displaying my homepage address in the address bar. Sometimes, the load bar will creep halfway, and part of my homepage will appear; typically, images don't load, and sometimes the page format gets wonky. Rarely, the homepage will fully load! I can even move through the homepage's image slideshow seamlessly. However, if I try to go to another page, I'm back at the 1/6 occurrence. Very rarely, everything works fine. Closing the laptop or Quitting Safari kills the connection, and I have to start this stupid process all over again. Finally, Firefox is either all or nothing; either the pages load and work fine, or nothing works at all.
I've done a DNS manual adjustment, I've created a specific Network, I've unchecked Safari from the iCloud options, I've run scans for malware and viruses (and came out clean), and I've done a clean reinstall of Yosemite. There's no need for me to tweak my router or contact my ISP; every other wireless application in our house is functioning perfectly. It's not the wifi.
Nothing's working, and I'm about to throw my computer out a window (not really, just frustrated). Any help would be so very appreciated.

My iMessages and FaceTime are not shooting on my iPad 2 it says my network connection is wrong but I have full wifi how do I shoot them?

My iMessages and FaceTime they won't let me set up them they say my network connection is wrong but I have full network connection iPad 2

Check Settings>General>Date & Time>Set Automatically>On. Make sure that the time zone setting is also set correctly.
If that didn't solve the problem, restart your iPad and try again. If that fails, reset your iPad and try again.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

Safari can't connect to the server, but firefox can

i have a few websites (mainly google sites) that don't show with safari but they do with firefox
i'm getting a "Safari can't connect to the server" error
to take DNS out of the picture i am looking up the ip address for the server and use the ip instead of the domain name so
http://74.125.19.103/images?client=safari&rls=en-us&q=test&ie=UTF-8&oe=UTF-8&um= 1&sa=N&tab=wi
works in firefox but not in safari
any ideas are more than welcome.
thanks,
tom

Hello Tom:
No I meant restart the computer. OS X rebuilds preference files as needed, but I am not sure what it does if you do not restart.
You could also reset Safari (that will also delete your cookies).
Just for the heck of it I would also run permission repair and also run repair disk from your software install DVD (those will probably not fix anything, but it does not take much time either).

Reset the iPad and try again. Hold down on the sleep and home buttons at the same time for about 10 seconds until the Apple logo appears on the screen. Let go of the buttons, let the iPad start up.

No Safari communication, but connected at full strength
