New Macbook Air - wifi connectivity problems

No ... update installed, nothing changed ... still timeouts : (

On .35 driver, curiously, when I ping without doing anything else, the result is between 30-60ms. But when I watch the video on Youtube, the result changes to 1-3ms.

Super_eight, could you confirm if the wifi driver changed from .35 to another?

Thanks🙂

pietrodelta7 ... where exactly do I find the version number?

Systemprofiler?

Haven't installed 10.8.5 on my Air yet, but for frame of reference:

OSX 10.8.4 pre-Wifi update: AirPortBrcm4360 version 6.3.0

OSX 10.8.4 post-Wifi update: AirPortBrcm4360 version 6.3.1

OSX 10.8.5: AirPortBrcm4360 version 6.4.1

They've updated the driver, but it appears it may just be the 802.11ac AFP speed issue, not our WiFi chipset issues.

I believe you can find the "firmware version" by this route, although there may be a faster way!

Apple icon click--then choose About this mac, then More info, then System Report; then go over to the left column: choose Network, then Wifi, then the firmware version should be seen beneath, in the column of information.

Uggh! After sucessfully fixing my ping values by rolling back to .22 - just updated to 10.8.5 and my pings are all out of whack again!!!! NOOOO!

Yeah, per the release notes for 10.8.5 that I mentioned a week ago, this maintenance release was to fix the wireless performance bug for AFP which was noticed right away in some professional reviews of the 2013 MBA (e.g. AnandTech).

It was only speculation of whether the updated wireless driver would also remove the latency bug found in the .35 driver, and would need to be tested for upon its release. Some folks are saying the latency bug is still there, and I'll confirm myself with a clean 10.8.5 build on spare hard drive against various routers later tonight.

And if the latency bug is in fact still there, I would stick with the original .22 driver for daily use.

Please, if you can, remember to put your build week and problem as I mentioned in my second post (I think). It would be SO useful.

Thanks

10.8.5 does not fix the problem, actually makes it worse. If I boot into recovery mode and use terminal to ping my local gateway I get 3-5ms pings +/- 1-2 ms. When booted into 10.8.5 pinging my gateway from terminal I get anwhere from 1.2ms all the way to 1000ms. In both cases I am a few feet away from the AP with line of sight. Have testest with current and last gen airport extreme, current gen airport express and other brands of AP. I am starting to think it's a hardware issue, otherwise Apple would have fixed it by now.

10.8.5 totally screwed up my ping values...had rolled back to .22 and had great ping values - now that's gone. Think I can roll back to .22 again via the same method even after installing 10.8.5?

I'm sure it's possible to do the manual .22 rollback in OSX 10.8.5 but I would highly recommend reverting just the AirPortBrcm4360.kext file (located inside IO80211Family.kext/Contents/PlugIns) and NOT the entire IO80211Family.kext.

Remember, this is a tech-head tweak and not for the faint of heart.

Um....why the cautionary closing (i.e. "not for the faint at heart") - is there some reason I shouldn't do this?

Also, would you please be so kind as to give me specific instructions for doing what you suggest (i.e. reverting just the AirPortBrcm4360.kext file). Also, where do I get the file to use to revert? Is it contained in the .22 driver (i.e. the IO80211Family.kext file I downloaded to revert back to .22)?

So looking forward to your instructions...working from home today on my remote server and the latency is driving me CRAZY!!!

THANKS IN ADVANCE ORCHETECT!!!

feeback from those taking 10.8.5 for a test drive making me groan. 3 months later, discussion headed north of 200,000 views, OS maintenance release doesn't seem to address issue and/or makes it worse? This 25 year customer waiting to buy an MBA is frustrated.

I want to cry 😟

I think this has to be apple's joke, this can't be true, they must have read this topic, how could they possibly make an update wich manteins the lag issue, knowing that a previous one .22 did not have it...

Ok, could some give us exact instructions on how to revert from last patch to .22 driver? We would be very grateful

PD: 10.8.5 patch is like getting the worst things from all patches, very high pings including timeouts, ping trick works no longer and I have disconnects from my own network
