WiFi continually dropping in and out all day long on new iMac

[Kaenon]

Wait for picture of Terminal...

I have tried holding cmd+alt+p+r thing.
I have created new locations in Network settings.
I have rebooted my router and my modem.
I've deleted the WiFi and restart and then reconfigure.
I've tried the Terminal ping thing, but obviously that doesn't work.
I've added 4.2.2.1, 4.2.2.2 and 8.8.8.8 as DNS servers.
I've gone into library>preferences>system configuration and renamed preferences.plist to preferences.plist.bak and rebooted to re-create the file, still no help.

I've tried everything I could think of.

The 3 PC users in my house connect to the WiFi fine.

Any other ideas?

So, there is no fix?

What can Apple then do for me?

P.S. it seems as if some of these iMac WiFi problems threads get deleted and I don't know why...

Yeah apple has done nothing.. do you have 10.7.2? I have a little better wifi now. Honestly if it is not fixed I am within my 14 day return window.....

Yes, I just got 10.7.2, but took forever because I could never stay connected to the internet...

Shame I'm obviously way outside my return window.

Do you have the option of setting DNS settings within the router? That seemed to help prevent my iMac falling off WiFi for some reason, it's also beneficial to set a static IP address in system preferences, as Apple's implementation of DHCP is apparently odd, which can lead to issues with connections dropping out and suchlike.

I tend to set it up using "manual address with DHCP" in prefs, and go for something like 192.168.0.100 just to make sure nothing else is interfering with it.

I changed a few different things and I don't believe I've had any drop out for the last couple of days. I think I did something further with DNS settings (not from the router).

If it comes back I will go for your advice, thanks.

This modem should solve your problems TRUST me!!!

I have tried the top of the line trendet 2011 adsl modem and the wifi dropped out on my iMac.

I have tried the top of the line 2011 actiontec wireless N modem and that had the same issues.

I have tried my ISP's 2007 actiontec modem and had the same problem.

Thank god for linksys.

It has never dropped out on me yet.
