Cannot access certain websites?

I too am having this problem, only with different sites. Going through the time capsule some sites I just cannot connect to at all, randomly. Sometimes they work, then sometimes they just cease to be connectable at all.

It's very annoying, and I know for a fact that the websites aren't down as I have accessed them without using the time capsule for internet access.

My setup is modem plugged into time capsule, then my imac connects wirelessly to the time capsule for internet access.

I'm having the same problem. My ISP first thought it was the router so I bypassed the router and I am connecting direct from modem to computer. On desktop with no wifi, traceroute shows I'm still trying to connect through an airport (starts with 10 rather than 70.) I've rebooted with airport off, deleted old network connection and added new but it still thinks I'm connecting through airport. Somehow, this is making it so I cannot connect to certain websites like geni.com. I'm going to try to call Applecare.

Change the service order, put Ethernet above Airport.

It must be an Airport Base Station bug that causes some people to see most sites except a few others.

I've had a similar problem -- lately have been unable to reach any Google sites (www.google.com, Gmail, Google ad servers, etc.). Once and a while they work, but usually they don't. Sometimes the IP addresses work directly, but usually not.

Our setup is:

DSL Router <-ethernet-> Airport Extreme <-wireless-> Time Capsule

The TC was set to extend the network, and allow clients. We changed the TC to NOT allow clients, so we're connecting to the AE (which is further away in our home) and now everything works fine. So maybe it is a TC bug, or maybe some other random thing... All I know is that we're probably going to wait until there's another TC update before we think about using it again.

I also have this problem. I cannot access my corporate websites from my mac, but Windows has no difficulty.
This is very annoying, and has made my Mac virtually useless at work.



Traceroute gives:

Solved my own problem.
VMWARE Fusion has several network processes running. Uninstalling VMWARE Fusion solved the issues with my corporate webpages.

In my case, changing the service order so that I was accessing the internet through Airport base station rather than through Time Capsule immediately solved a problem I've been having for weeks (accessing a few web sites - most were fine). There must be a bug in Time Capsule, I think.

I had faced similar issues with my corporate messaging server. Either of the following works:
1.# dscacheutil -flushcache
2.Use third party tools like Onyx to remove all cache,then reboot.Reboot is essential.

My linux box with uptime of 11 months doesn't face any of the 'cache' flushing issues and resolves/traceroutes/pings like there is no tomorrow 🙂 . Go figure.
