I can't connect to 1 certain website.

Question

I can't connect to 1 certain website.

I have a home network with an Time Capsule connected to the ISP's DSL modem and I connect 4 macs, and 2 iPads and an iPhone when not on 3G. Everything is running Lion or the latest iOS.

Last week I was able to connect to a website and easily go through their shopping catalog. Suddenly on Monday the page wouldn't load in Safari. The address bar would get blue about 1/2 way then I would get the error 'can't connect' Same problem using Chrome. I get the same problem not matter which computer I use from my network.

I talked to the business and they said the site was up and they don't block ISPs or IPs. My ISP is at a loss as they can also connect to the site.(plus they are not Apple friendly) I can connect to the site with my iPhone on 3G. I can connect to the site from my neighbour's network. If I connect my MBP to the modem with an ethernet cable the site loads.

I reset my Time Capsule to factory defaults and started from scratch but I still can't get that site to load, it just hangs. I'm sure that it has something to do with my router but I can't seem to nail it down.

Has anyone every seen this problem before?

have you tried to use the website IP address instead of the DNS?
try this, launch terminal (/applications/utilities) and write "ping -c4 <website>" (change <website> for the website address, like www.apple.com)

copy the IP address (string of numbers separed by dots. like 209.85.147.83), paste this on your browser (safari/chrome) and hit return.

if it works, you have an issue with the DNS, you can try to use google's public DNS servers (http://code.google.com/intl/en-uk/speed/public-dns/)

As I mentioned, I can access the site when I connect directly to the modem with an ethernet cable. I can't access is when I go through the TC router.

While connected to the modem, please do as follows:

Please launch the Network Utility application by entering the first few letters of its name in a Spotlight search. Select the "Lookup" tab and enter the address of the problem site in the address field. Press return. Post the output -- the text, please, not a screenshot. Then select the "Ping" tab and do the same.

Repeat while connected through the router.

The modem is using 142.165.21.5 as its preferred name server, which is what your ISP specifies:

SaskTel DNS Server Information - SaskTel

The TC is using 142.165.157.5, which is in the same netblock, but still different. I suggest you delete the DNS presets and let it get the name server addresses automatically via DHCP by renewing the lease. Save the changes and try again.

I'm not sure how to delete the DNS presets. With Airport Utility/internet/TCP/IP tab I see the renew lease button but the DNS server addresses are greyed out.

Manually change the DNS settings on the TC to the ones shown on the above-linked page. Restart the TC. Any improvement?

Then something is wrong with the TC. You've ruled out everything else. I don't know of anything in the settings that could cause the problem you have. Anyway, you've already reset it.
