Thanks all. It seems that all is fine now. At the first sign of trouble I'll re-post.

Well, I have a Phillips TV set to standby just half a metre from my Mac and a portable gigarange phone with base station.

I'm sorry I missed the conclusion of this thread. FYI, there do appear to be some permissions problems with the machine that may be affecting Airport.

Also APE (APE is not recommended) appears to be reporting some problems with the Security Agent.
There are also the following messages, but these may be the result of problems with Active Directory, with which I'm not familiar.
I would look at a system reinstall as being a good idea.

cannot connect to particular websites
 

I have an iMac G4 in OSX 10.4.6.

I've been accessing www.nytimes.com for years. Since 3 weeks ago Safari or FireFox or whatever browser cannot connect me with the new york times website.

I've cleaned cache, repaired permissions using applejack and still I cannot get access.

My wife's PC is connected to the same router and I am able to access the New York Times website on her computer.

What is it about my iMac that's blocking this particular website?

First, I would log in as a different user and see if the problem persists. Let us know how that turns out.

cannot connect to particular websites
 

Thanks for your response.

However, I logged in as a different user and still I'm unable to access 2 particular websites. One of them being www.nytimes.com.

Ok, now post the relevant logs concerning this phenomenon from the Console in the utilities folder. You should be able to find it because the logs are timestamped. That should help give us an idea of what exactly is causing the error.

My previous connection problems have been solved. Thank you.

I can connect to the New York Times website from both a G4 (10.3.9) and G5 (10.4.3), with both Safari and Firefox.

What error message does your browser display?

Have you tried other similar websites? e.g. http://www.washingtonpost.com/,
http://www.iht.com/pages/index.php, http://www.newyorker.com/

Start-up flashing planet
 

I restart my iMac and I get a small flashing planet that continues flashing on and on without actually starting my computer..

If I unplug from the router and restart, I get a flashing planet going for about 15 times and then it turns into an alternate flashing question mark (?) and Finder icon (2 faces looking at each other) for about 15 times and then I get the apple icon and the computer reboots successfully.

I then have to plug into the router to get online.

How can I fix this Start-up problem?

This is a problem with my computer as my wife is also hooked up to the router without problems.

History:

I talked with a friend who works for Apple on & off and he told me to ping www.nytimes.com in Network Utility. I cannot remember all that happened after that but I crashed.

After resetting my router and cable modem with the help of Linksys tech support I was able to access the new york times and democracy now.

Network and startup problems are probably unrelated.

Go the the System Preferences and set your current startup partition again, your Mac seems to be confused about where to boot from.

If that doesn't help, you might need to reset the nvram.

I'm not sure why you posted in this thread as it doesn't seem to be related.
But in any case, when you get that "planet", it means that your Mac is trying to boot from the network instead of from the OS that is on the hard drive.
You should open up the Startup Disk preferences panel and set the startup disk to be your internal disk. That should fix it.

Thanks so much Hayne. You were right. I was booting from the network instead of the hard drive. It's now fixed.
