Make a New Location, Using network locations in Mac OS X ...
System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.
System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.
The interface that connects to the Internet should be dragged to the top of the list.
Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.
Try putting these numbers in Network>TCP/IP>DNS Servers, for the Interface you connect with...
For 10.5/10.6, System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...
Also, turn off IPv6:
System Preferences » Network » AirPort » TCP/IP tab » Configure IPv6
Or whatever interface you connect with.
This seems to mirror the problems I am having too with my Intel iMac. (see: https://discussions.apple.com/thread/4106764?tstart=0)
I managed to get my Ethernet connection back but it has been unstable. No definitive path to restoring normal connectivity has been found as several pathways seem to work, including putting computer to sleep, rebooting modems/Airport, and restarting.
What is the significance of those addresses you cite above...? 188.8.131.52 184.108.40.206
DNS Servers are a bit like Phone books where you look up a name and it gives you the phone number, in our case, you put in apple.com and it comes back with 220.127.116.11 behind the scenes.
These Servers have been patched to guard against DNS poisoning, and are faster/more reliable than most ISP's DNS Servers.
There are many more if you need.
Open System Preferences>Network>Configure>Proxies Tab, make sure none are set, like for HTTP & HTTPS.
10.5/10.6 instructions, System Preferences>choose interface>Advanced>Proxies Tab, make sure none are set, like for HTTP & HTTPS.
See if you might have this malware redirecting DNS queries...

If it's happening with both your Kindle Fire and your iMac, it's likely to be something related to your network connection, not an error or malware on the computer. It could be a misconfiguration of your router, or it could be a larger problem with the connection provided by your ISP. Why it wouldn't affect all devices, I don't know. Perhaps it's a sporadic issue with someone that has gotten cached on those two devices. This will be a bit of a pain with an iMac, but can you find a way to test it with a completely different network? Try at a friend's house, for example.
Turns out the kindle fire thing was a fluke. The next day it was working fine and has been for over a week.
I did move my physical computer into the room where my internet connection is and literally plugged it in to the internet and it works that way...so it has to be either something with time capsule or something with airport.
Thank you for the advice. If I can get it to someone else's house I'll try that...that should at least tell me if it's airport or time capsule I would think.
So, I managed to fix it. Once I found that the browsers were open when hard-wired to the internet through an ethernet cord, I just went ahead and re-configured TimeCapsule and started from scratch creating a network. I still don't know what caused the problem, but at least it seems to be working now.
Thanks to everyone who responded.
Browsers won't open pages, but internet is working perfectly?
I was watching something on Netflix and it started getting choppy, so I tried to fix it by reloading, which didn't work. Then I tried to restart my browser... Now, it just won't do anything.
"Neither Safari nor Firefox will open web pages. However, the computer is connected to the internet."
I have tried the network diagnostic and it says everything is fine. I have ethernet. I've run about seven different anti-virus softwares on it and can't find anything. I did the reboot, disk utility, set up a new address... Time Machine didn't work either.
I was told I might have Google Redirect Virus or some other rootkit.
Nothing I did fixed the problem, even temporarily.
Im have the same problems, This link would not openRe: Browsers won't open webpages but internet connection is fine had to past it into Chrome . fire fox has trouble too and Chrome also. it just gets worse as i try to fix things , been on here in another forum trying to fix it, Gone round in circles.
