rMBP 15 = poor Wifi performance

[Space_Chief]

My retina MBP 15 (2012 edition) is experiencing Wifi drop outs on my home Airport Express 5th Gen Wifi network. This happens when I connect my LaVie Z running Win 8. The Mac remains connected for about 2-3 min thereafter the connection remains active but download speeds drop to 0 and sites get DNS errors. Switching Wifi off and on again fixes the problem for the next few minutes. The only way to fix the problem permanently is to disable Wifi on the LaVie. The LaVie is dual band but running on different frequencies, having the Mac on 2.4GHz and the LaVie on 5, or vice versa also does not help. The signal strength is full though.

In fact I noticed that my 3rd Gen iPad has better Wifi performance and range than my rMBP 15. I've noticed Wifi problems already with my old 2010 15 inch Macbook Pro. None of my PCs have this problem. Oh well.

Have you tried disabling uPnP in your router. I had a similar problem with a Japanese Sony Vaio - this seems to have fixed my problem. There might be some type of IPv4 vs IPv6 issue.

I'll try it, thanks for the tip. My Airport Extreme works mostly as an AP connected to my Netgear DGN. I'll disable it on my NetGear. Ta.

I.e. Switch off auto channel negotiation.

Alternatively (OS X version dependent), switch to an earlier kext; https://discussions.apple.com/thread/4176584?start=60&tstart=0

Hi,

Thanks for that. Disabling uPnP did not really help but I'll look at your suggestions. I do have two seperate issues I think. One is the general poor performance in terms of range of my MBPs. The other is the interference the JDM machine causes my rMBP. Putting the rMBP 2m away from the AEBS and the Lavie 7m did not help either, so maybe it's a network problem and not so much a Wifi signal problem which remains good. I'll check out your links.
