It’s incredible the amount of people with this issue, world wide. My iMac has gone nuts too. I saw a small difference when switching the channel in the router, i also see differences when you restart the machine and come back fresh, but all of these will only work for a very short period of time. I’de less than an hour or so. Will do the cmd+p r keys in the boot, see if i get any where. I also tried some DNS configs, and some automatic pinging on yahoo servers, lol, and that was because wifi just kept dropping so i had to keep it downloading something etc.. Also have to mention that there was an update, recent, February 2012 if i’m not mistaken, that sorted out some problems with Wifi in Lion.

Really interesting to hear that it may just be a software issue. I haven’t had any issues lately, but sometimes they will randomly pop up again. Changing my router channel has worked well though.

My problem is about 50% slower wifi speed in macos than bootcamp/win7

Tried several diffrent solution no go, and if it works in bootcamp/windows 7 that means its not hardware related to me.

Only thing i havent tried is reinstalling macos but atm i dont have the time.

My comp is, imac i5 27″ mid 2011

Just a note from a network engineer — don’t screw with the MTU. Lots of apps depend on the value being 1500.

Hi,
Really thank you for your suggestion about changing channel number in the router. It works for my iMac 21 inch 2011! Really appreciate it! In the past , I could not use my iMac wirelessly more than 10mn , it disconnects without reason.Now with your solution, everything is good, I am really really happy! Thanks!

Hi Ian,

I changed the channel to 3 now…(didn’t read your instructions properly the first time).

Hoping this works…
