2012 Retina Macbook Pro WiFi problem

I have the same problem. Unfortunately this is a common problem when it comes to Apple notebooks. My MacBook has the same problem. I have had this problem in Snow Leopard, Lion and Mountain Lion. Some of my friends share the same problem. If you haven't harmed your MacBook in any way then bring to an Apple store, they could fix it for free if the problem was caused during the production process.

I have the same problem as well. I own a Macbook Air 2012. When I was using Lion the problem was less.It became worse with this mountain lion.

Apple must fix this problem.

I had this problem on my Macbook pro with retina. When I would wake it up from sleep the wifi would cut in/out for a few seconds then work. And when it was sleeping it would drop wifi (downloads would pause).

This is what I did today and so far it's fixed the problem:

1)reset smc

2)reset pram

Happening to me too. Macbook Pro Retina Display with Mountain Lion. I'm experience occassional drops while actively working on my Macbook that requires me to turn off Wireless and turn it back on to get a connection. I've noticed this twice in two days.

I'm had my Macbook for about a week and immediately installed Mountain Lion, so I don't have a previous version to compare with. I could turn off Bluetooth at the moment, because I'm not using any Bluetooth devices, but it is likely I will be getting a bluetooth device in the future, then this workaround won't be useful.

I hope Apple can come up with a software patch?

This is the exact problem I am having. Wifi is connected, but packets randomly start dropping every few minutes.

Bluetooth has been completely disabled so that is not the issue.

Purchased a new dual-band router and the problem persists on both 2.4ghz and 5ghz.

I don't know what else to try besides returning this thing. The answer also shouldn't be "buy an Airport" since no other device besides the Retina has any issues using wifi.

Same here ... i am sitting next to a wideband router and all my air and mbp drop wifi every few minutes. The signal strength stays full, but there is no internet or a tremendous lag in loading pages etc.

What a disaster -- I told myself years ago I would never update an os without waiting, and the one time i breakthe rule, i am paying for it ...

+1 to the wifi issues on a brand new MBPr. it's kinda actually driving me nuts with how long it takes to load a simple web page on my own home wifi network. my iPad and appleTV2 load things just fine on the same network, so i am pretty confident it isn't the network that is the problem.

also, i've experienced it on other wifi networks, soooooo i'm pretty sure i can blame the MBPr. 😠

I have the same issue with MBPr even the bluetooth is off, 10.8.2. My first Apple device and out of the box the trackpad and wifi does not work. Not sure Apple=Quality it should for the price they charge.

Having the same issue on 2012 MBP Retina but not on my 2012 11" air. Both machines running 10.8.2

PRAM clear made my issue mildly better. I no longer have to power cycle the Wifi every 10 minutes, I can get at least an hour or 2 now! How exciting

Build quality on this $2300 laptop is quite pathetic

IS it possible these guys put out an update and still didn't address this issue ? 10.8.2

I have this problem too; however, I do not have bluetooth enabled so I can't turn it off to resolve the problem.

I am very disappointed that I paid a small fortune for my 2012 Macbook Pro Retina Display and the Wifi ***** like this. In my case, when my laptop sleeps, it drops the WiFi network signal and can't find it automatically; I have to toggle the WiFi on and off.

unfortunatelly, I have just come across the same issues as described here but with a little extra twist. MBP retina, 16GB RAM, 256 GB HDD. I have installed Lion upon its release and never had a noticable wireless issue until the last 2-3 weeks.

Wireless keeps dropping or fully dissappears. Turning it on or off doesn't change anything - it'll keep searching for a while, then tries to connect for another while and end up with "no Internet connection". This might go on for anything between 5 and 30 minutes (note: 2 iphones, 1 PS Vita, 1 bm air all use the same routera and experience no drop or issue). If it connects, loading times can range up to 2 minutes for a site (e.g. google.com). What I have found is, that clicking on sleep mode and immediately pressing a key to get it back resolves the issue for a short while (turning wifi on and off doesn't). It's a little odd and as many others wrote: a machine for that price shouldn't come with issues of that sort... I am very dissappointed.

Bluetooth was never enabled, so that can't be it. I have tried everything else described above and in various other forums.
