iMac Wifi Problems

Bought my iMac in July and have had problems with the signal dropping and having to turn airport on and back off. I have the same router I have had forever with my powerbook. The only thing that I can figure is that it is the iMac. Any suggestions?

Thanks

Lion 7.2 was only recently release, give that a try if you haven't done it. I had the same problem when updated to Lion, but itís now mostly gone with the latest update.

I've had this issue on the iMac also since buying it in June/July running Snow Leopard, (but never on 2 PCs, a MBP, 3 iPods and an iPad). Curiously watching around for solutions .

Went to 10.7.2 tonight, and waiting to see if this has an effect.

I don't know, if I had the same problem as described by you. My wifi connection was still active, but no packets went over the air anymore - it looked like wifi has been stalled. Turning wifi off and on made it work again for the next few minutes (iMac 2011, Snow Leopard and Lion).

The solution that worked for me, was to turn off the WPA2 CCMP option at my router and switch back to normal WPA2.

Note that I also have a MacBook late 2008 and an iPhone, that worked fine for years with these router settings. Only the new iMac made trouble.

Hope that helps,
Maruu

not sure if would work for you but...

my older imac (mid 2006 intel 2.0) was having issues loading pages extremely slow ect...

read somewere and works great....change/add dns server setting...system pref/network/(airport) advanced/+ add your isp's own dns server numbers or others (example google 8.8.8.8 and 8.8.4.4)

after i did this,pages load great...

I have had this problem since upgrading to Lion after I bought my 2011 iMac.

The problem with my Airport's wifi connection, however, also extends to my wife's iBook, which is running 10.5.8, I believe.
