IMac connects to wifi, but won't open all websites

I can get email, but only loads certain websites. Facebook and Google work, but not Amazon (and many more). I get an error message in Safari "Safari can't open the page because the server stopped responding". The iMac connected perfectly before, the only thing that has changed is that we were having people use our wifi (of which data is limited since we live in a rural area). So, we added the security feature "Wireless Mac Authentication" to our router. We have added the addresses of all of our devices and they all are working fine except for the iMac. I have tried changing the DNS to the same that is on my Macbook pro, but it doesn't help. Also, had a WEP for the router, but changed it to a WPA because I thought maybe that was the problem, but it did not help either. Thanks for any help!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

I am connected to wifi, but can't open webpages or collect mail

I am connected to wifi, but can't open webpages or collect mail. I have tried to reconnect; to forget the network, all those things that should hepl. My phone and my computer recognize the network, the ipad doesn't. I mean I am connected and have a full scala of connection bows, but nothing happens.

You iPad recognizes the wifi signal, but is not connected.
Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list

My ipod touch says it is connected to wifi, but won't run anything that uses it like safari or itunes, and I don't know how to fix it

Can anyone help me? my ipod touch says it is connected to wifi, but it won't run anything that uses wifi like safari or itunes, and I don't know how to fix it

You didn't indicate if it ever worked. If it NEVER did, the problem could be caused by a firewall in the router. For reasons that I do not understand, that will affect IOS (iPod/iPad) communication but will not affect computers or other devices.
You will need administrative access to the router. If a firewall is present, turn it off and test the iPod again. If it works, turn the firewall back on but weaken it a notch and test the iPod again. Repeat as required.

I am connected to the Internet (Wifi) but can not open any website

Power down the router. Unplug it from the wall. Wait 10 minutes.
Plug it back in. Power it on. Wait until all the lights are lit up properly.
Restart the computer.

My iMac can discover WiFi but won't connect how do i fix this?

My iMac will discover WiFi connections, i type in the right password but it wont connect how do i fix this?

A lot of older iMacs only support the original Airport, and not Airport Extreme. PowerPC (PPC) iMacs that have extreme are limited to 802.11g, and can't do 802.11n. Those with the original airport only support 802.11b, and the insecure WPA/TKIP or WEP encryption, and are better served via ethernet to a WiFi ethernet bridge.
The airport card typically is not built-in. Verify with http://www.everymac.com/ what the status of your iMac was, and/or see this article:
http://support.apple.com/kb/HT2256
Intel iMacs that are Core2Duo can be upgraded to 802.11n with the 802.11n enabler. You'll have to contact the Apple Store online nearest you to determine if you can still download it, as it is not on their website.
To determine if you already have it, see this tip:

Ipad tries to connect to wifi but won't .....

My husband was watching Netflix on our ipad and it suddenly a message came up "you have no internet connection". We have a router in our home (but no wireless plan) so we can only use our iapd where the is wifi. We tried resetting the router but husbands laptop works fine with wifi. When the ipad tries to connect and I watch the screen and it either will not recognize the router password or next to the WiFi will say "TRENDnet"(our router), then "Not Connected", "TRENDnet", "Not Connected", like it tries to connect and does for a second and then doesn't. I suspect it is not the router because husband's laptop works fine. Any help appreciated. Ipad is a version 1, regifted from Mom when she bought her new Mini. Thank You!

1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.

IPhone connects to WiFi but won't work.

Ever since I got my iPhone 4, it connects to the WiFi but it won't do things using WiFi so I usually end up using 3G. But this only happens at my house. I works perfectly on the bus and at school. Same thing happens to my sister's iPhone 4 and recently we had guests over and I connected one of them to the WiFi and she had the same problem (iPhone 4) My dad has an iPhone 5 and I'm pretty sure it works perfectly for him. Please help. I've tried everything. Forgetting the network, resetting my phone, restoring my phone. Any suggestions please?

Seems to be a problem with your WiFi router.
If your iPhone can not access the internet using WiFi, due to low signal strength, low internet speed, router overload, or perhaps a wrong router setting (child safety lock, firewall?), it automatically accesses the internet using 3G.
You just have to find the error...
Good luck ;-)

Just updated MacBook Pro, connect to WiFi, but unable to open any of the downloads, Just updated MacBook Pro, connect to WiFi, but unable to open any of the downloads

I just updated my MacBook Pro with the latest release of Lion. Now I am unable to open downloaded content. I have no trouble connecting to WiFI.
Any ideas?

What is the prompt that comes up when you try to open a downloaded file? Where did you download the file from? What kind of file is it?

My Macbook connects to Internet but won't open webpage

Thanks in advance for reading this. My Macbook shows various Airport connections but hasn't worked for a while unless it is directly plugged into my modem. I just set up a new modem and connect via Airport. The Airport signal shows that it is strong and connected, but I cannot open a web page. Any ideas? I'm not sure of my operating system--I bought this mac in June and I know I don't have the fancy new one. Thanks so much.

Your post is confusing. Your airport can show many signals but that doesn't mean you're on any of those networks - which should require entering some sort of password. Where I'm sitting now, my airport icon shows 9 networks of which 7 are locked and I'm on one and haven't tried the other that might be open. You need to join a network, which you can do by selecting that option from the drop down menu - if you know the password. (You can also open the Network system preference.)
The version of the OS doesn't matter much, though what the airport drop down menu shows will be different from 10.4 to 10.5.
In other words, it sounds as though you're confusing having a wireless signal with being connected to the wireless network and thus to the internet.

One wifi spot my iPhone connects to wifi but not internet. All other devices connect to internet.

My iPhone connects to wifi just fine. When it does it connects to the internet just fine except in one location. My house. My MacBook Pro, my wife's iPhone and her iPad get on the internet there just fine. My Iphone's IP address it begins with a 10. At my house it occasionally will connect to the internet through wifi but I leave wifi off there because it is so intermitent.
Any suggestions?
I have not seen this problem addressed.

Can you ping a website using either Network Utility or Terminal?
