Mountain Lion wifi problems?

Hi there, Not sure if this is the right post for this but I am running a 15" MBP Retina with Mountain Lion, all of my software is up-to-date.
This evening I was on my home wifi like normal, and my computer all of the sudden dropped the connection.Other wifi connections were still showing up in the dropdown and Both my wife and I's iphones were still connected to the home wifi. I figured the router needed to be reset so I did that, and no change.
I've tried manually "Join Other Network" and still nothing, I've cleared my preferred networks list and then re-added the home wifi to the list, still nothing. Ran a scan to make sure it wasn't a spyware bug or something like that, nothing. From what I understand this issue is pretty common with Lion and Mountain Lion.
Can anyone help? I'd prefer to not have to go in and change my router settings as that isn't really fixing the problem, it sounds like its in the Lion software, wondering if there are any other fixes to this problem?
Thank you in advance!

Mountain Lion WiFi Problems (recap)

Folks, wanted to recap this as I am finding the problem much more broad than my original post (here: https://discussions.apple.com/message/19123146#19123146). Here's my setup:
MacBook Air 13", Mid 2011
Mountain Lion
Wifi Problems, cannot connect to open wi-fi and Sprint hot spot.
CAN connect to Time Capsule (at least I could before I started futzing with my setup while on the road)
here's what I've done so far:
Reset SMC
Zapped PRAM
Reduced MTU to 1300
Set hotspot to 802.11g only
Set IPv6 to Local-link only
Set up a new user account, no connection there either
Repair disk
Repair disk permissions
Removed WiFi in networking control panel and re-add.
Remove the network from control panel AND remove keys from Keychain
What I have not done but will try later:
Reinstall ML
Disable WMM
Observations:
ML seems to think there is a connection to the wi-fi, but it can never get an IP address
Using a static IP on the network doesn't help the problem
My hotspot never really registers the MBA as a connection

Tell you what worked for me .. finally.
Had two Apple technicians on the case - over the phone. Have to say, those guys are awesome! - with patience of saints! But to the point! As there was nothing obviously wrong with operating system, they promised to call me back the following day but suggested talking to my Internet Service Provider about the router (D-Link router). The ISP remoted to my iMac and logged into router site and changed channel selection from automatic to manual. He chose channel 13, and suddenly my MBA connected and has been connecting smoothly ever since. The reasons I had problems was that there was over 10 available wi-fi networks in my flat, some of which showed as having stronger signal than my own. The ISP guy told me this, increasingly, becomes and issue, especially in blocks of flats - the ether is filled with wi-fi networks to the point of saturation. He also said, his choice of channel 13 was just a fluke and it might turn out I'd have to change it again.
So, although the problem is now solved, there still remains this one nagging question: Why did the wi-fi connectivity zonked right after Mountain Lion upgrade?

After installing Mountain Lion, WiFi problems

I installed Mountain Lion on my mac mini and have been having intermittent WiFi problems ever since. It seems to be getting worse, connection is now being dropped several times an hour as opposed to several times a day. I have tried all the suggestions that have been put forth with no luck. My iPhone can use the WiFi with no problems. What I have found that seems to work everytime is to go into the Network system preferences, turn WiFi off, and then immediately turn it back on. I am using the most recent Apple Airport Extreme. I urge Apple to fix this bug quickly.

Don't know what to tell you, but I also have an AEBS-Gen5 with a MBP Retina and Mac Mini using WiFi. Both are running Mountain Lion and I don't have any WiFi connection issues. Two iPhones in the household use WiFi with no issues along with a printer and 2 Windows 7 laptops.
First thing I would try is to shutdown all computers connected to the AEBS. Then power off the AEBS and finally the cable/DSL modem. Then reverse the order and power on the cable modem, wait for all the lights to be solid, power on the AEBS, wait for the light to show solid green; then power up a computer that uses WiFi.
If the above doesn't work, you might try repairing permissions via Disk Utility. If that doesn't help maybe a PRAM reset would work.

After a long in "stop" period, the internet connection (ethernet) doesn't work. before updating to mountain lion this problem didn't exist.

Gave up on the GUI. This script derived from http://blog.netnerds.net/2012/07/os-x-how-to-setup-nat-on-lion-and-mountain-lion / seems to work for me:

Mountain Lion WiFi: Major Problem

I have a late 2011 17" MBP and did a clean install of 10.8. Ever since that time, I am unable to maintain a useable connection to certain access points. At first it seemed like the internet was slow, but eventually pages loaded and I didn't think too much of it. But then I started accessing lots of files on my home server (OS 10.6.8 Server) and the Finder was beachballing with nearly every click. I plugged in an ethernet cable and all the problems went away. Went back to wireless, the beach balls and sluggishness came back. Then I rebooted to my 10.6.8 partition and connected and used the network just fine on the wireless, as I had been for years before on this MacBook and my previous MBP.
After searching through forum posts I saw that some people were blaming this Mountain Lion bug on whatever runs the 5Ghz connections. So I forced my MBP to connect to the 2.4Ghz radio. While I did have one glitch (a video didn't play smooth over the network initially) it has basically been solid ever since. Yesterday I spent the day at a client where I run the network and my 5Ghz problems came back. I would have to power cycle the Airport to get the connection useable again. Both my home network and this client's are running with Ruckus Wireless ZoneFlex 7363 access points. At home I also have an Airport Extreme from a few years ago that I use as a router with wireless disabled. I turned that on and while I didn't really use it for all that long, it seemed to work at 5Ghz--but I didn't really use it that long and need to do more testing.
My exact setup:
1) Clean install of 10.8
2) Late 2011 MBP 17"
3) Ruckus Wireless ZoneFlex 7363 firmware 7.3.x
I hope this is fixed soon or someone discovers a workaround.

+1 -- I'm basically in WiFi h*ll since upgrading. 10.8. Injected all sorts of issues on my network and devices where 10.7 was rock solid. Mid 2009 15" MBP dropping connections on Linksys E4200 at 5GHz. If I switch to 2.4 GHz, no issues. At home I have an Airport Extreme running 2.4 and 5Ghz. I am experiencing drops on 5GHz there as well. I upgraded to 10.8 instead of a clean install, but from reading the forums that doesn't work either. I have a Mac Mini that is wired and no problems.
A couple of other interesting pheneomenons since upgrading;
new model Airport Express:
I bought one the same day as upgrading to 10.8 and immediately encountered issues setting up the AP to extend the Airport Extreme network on 5GHz (kept returning "encountered unkown errror" when writing the configuraiton to the AP). I had to use the old 5.6 Airport Utility to get it to save and 2.4GHz to keep devices from losing their connections. Other weird thing is the 'Back to My Mac' icon on the Airport Express stays yellow where the Airport Extreme turns green.
new model Apple TV 3:
Flawless prior to upgrade day. Now, no longer works on either frequency. Started with dropping Home Sharing connections, then progressed to losing WiFi altogether. It won't even run on the ISP provided router at this point. If I do a reset or a full restore in iTunes, it works for about 5 minutes and then drops the connection and resets itself to the main screen with only a 'Settings' and 'Computers' icon.
I know, possilby conincidences and unrelated but curious issues for sure. I've pulled out each piece and tried to see where the problem returns but no luck. I have recommended and deployed a lot of Apple devices over the years and this is the first time I've ever had problems. One family member seems to be having a similar issue with a new Apple TV3, Airport Extreme and iMac on 10.8 combination. A little embarrassed for having made those recommendations now. The only thing that solves it for me is rolling back to 10.7

Mountain lion wifi is not working properly

After installing the Mountain Lion in my imac late 2011 model, 27", it started to show wifi errors. I tried to restart the system to see if the wifi connects back or not. It shows as connected but not possible to browse the net.
I then turned-off & turned-on the wifi alone and I found it got connected and was able to browse. Few minutes after the browsing the wifi connection went off and was not able to browse.
I repeated the same rectification method and was able to get back to the web browsing. Several times since mt. Lion is installed I experienced and it is now three days.
Any one experienced the same errors and found a permanent solution please share the method.
Thanks

Hello you all,
I also had the problem of a disconnecting wifi while my imac was sleeping. I did not have the reconnecting issue after sleep, but the lost connection issue during sleep which made it impossible to reach my imac for things like homesharing, apple tv or remote desktop. I have a late 2012 iMac with a clean ML 10.8.2 on it and wirelessly connected to an apple time capsule (same as an airport extreme). My partner has a mid 2007 iMac, also with an ML 10.8.2 on it.
I tried every single solution I could find on the internet, such as changing the router's security from wpa2 to wpa, changing the MTU from automatic to manual 1453, router reboots, re-installations, re-configurations, keychain clean-ups, everything.
Eventually I solved my problem with these steps and now it works as a charm. I can still find the iMac with the remote app, even after 12 hours of sleep:
My time capsule router is set on automatic MTU and encrypted with WPA2 and I use the 5Ghz network!
1. Cleaned all the wifi passwords in keychain on my iMac
2. Created a new network location in system preferences
3. In this location I deleted the bluetooth pan and bluetooth dun connection.
4. In this location I changed the preferred connection-order to wifi on #1 and ethernet on #2.
5. Restarted my iMac.
Now I still have a connection when it sleeps and I can wake it to low profile using the remote app (homesharing) and everything works fine.
Hope more people wille be helped by this.

Mountain lion wifi, mountain lion wifi

Soy usuario de Mountain Lion en un ordenador macbook recién comprado y la conexión inalámbrica (airport), falla constantemente. Es un problema que ya tuve con un macbook del 2006 con OSX Lion, al que decidí reinstalarle Snow Leopard.
¿cuándo saldrá una actualización que resuelva el problema de pérdidas de conexión inalámbrica?
Gracias.

Creo que he corregido el problema.
El caso es que ni el Servicio Técnico de Apple, ni tampoco la compañía que me sirve internet, han conseguido solucionar el problema, pero hilando, hilando, hice lo siguiente y eliminé el problema:
- Entrar en la configuración del router-wifi/avanzado/Rate (o lo correspondiente).
- Normalmente, el ratio de descarga estará en auto, pero tenemos que limitarlo al máximo de Mb que tengamos contratados, ya que algunas compañías, al dedectar que hay más tráfico de datos del contratado, cortan la conexión. Por ej, si tienes contratados 5 Mb, pues pones el ratio en la cantidad máxima posible, para que no te sobrepase ese tope de ratio.
y ya está, problema solucionado.

Mountain lion wifi issue

Ok. This is super frustrating. Its been three generations now since this wifi issue. I have mid 2010 MBP with broadcom drivers. The wifi wont pass traffic with cisco APs. The only fix is disable 11n rates then only it will connect. I had to downgrade the driver to 10.61 etc to fix that issue. Today i upgraded to mountain lion and surprise.... My wifi is pretty much useless... Pings to default gateway are pn an avg 4ms and good minutes of ping losses..
This is just not acceptable. This is stupid and lame and apple nees to fix this pronto..
Geez apple is making billions of revenue and freaking cannot fix a stupid driver issue... I want my money back... And above all give me my time back which i spent to tshoot this problem...

This is on Mountain Lion drivers

Do i have a virus, or is it just Mountain Lion teething problems?

Ever since i upgraded to Mountain Lion, it has impressed me, but also shocked me. It has some really useful features, and looks beautiful, but i cant help wondering if Apple is loosing it's touch, when it behaves like Windows Vista. The first problem was that it randomly kept restarting whilst in sleep, whick causes lots of problems. That has stopped now, but the are even worse problems. Web based application ofthen crash and are unresponsive, and it denies the existance of my Air port, which it is connected to, which keeps all the backups. Also, I recently noticed a Java DMG in Disk utility, but it wasn't in finder, when i looked, so i ejected it using disk utility. These are all tell tale signs of a virus, however, it also claims that the bootcamp partition doesn't exist, (yet i can still boot from it, and use windows), and also it told me that it couldn't eject Macintosh HD, because itunes was using it. Why would I ask my best computer to commit suicide? Also, when i connect my portable hard drive to it, it doesnt show up, but if i connect it in Windows or on another Mac, it works fine. So, it's either a virus, a reliability issue in Mountain Lion, Please help.

You don't have a "virus." That's the Windows way of thinking. You have a misconfigured system. What exactly happens when web-based applications crash?

Logic 9 + Mountain Lion = Performance Problems

Hi,
After months of debating to upgrade to Mountain Lion, I did it (and regret it like iOS 6).
I'm just wondering if anyone gets the issue with Logic 9, where it works for around an hour no problems, then the CPU meter goes mental and causes glitching in the audio no matter what I/O buffer size I choose, or what sample rate my projects in, OR how many plugins/instruments I have open?
It's really starting to affect my clients as to solve the problem the OS needs a full reboot.
I am fully updated in Software Update and it worked perfectly until Mountain Lion.
Hope there is a solution!
Tim

Your question is too vague... More details are required...

Mountain Lion download problems with Lion 10.7.5 (no VirusBarrier issue)

I have a mid-2009 Macbook Pro. From the factory it came with Snow Leopard but has since been upgraded to Lion OS X 10.7.5. I do not have VirusBarrier, I am writing from a recently clean-installed Lion.
I have now been troubleshooting my Mac for several days. When I wrote first, I had an issue with Safari having been damaged and so I wasn't able to reinstall Lion - but after a certain extremely helpful community member I finally succeeded in installing Lion.
But the issues with the App Store still persist. All my Mountain Lion downloads fail, getting the error message "can't verify, might be corrupted" what many here have also been getting. However, most solutions were related to VirusBarrier (which I don't have), or /var/folders errors (Console does not show any var-related errors).
So if it's not a var-related issue, or related to firewalls or virus softwares (I have disabled the Firewall and I have no virus software installed), what could it be?
When the download and install of ML failed last time, Console showed the following messages:
11/30/12 11:54:44.617 AM com.apple.SecurityServer: Failed to authorize right 'system.install.app-store-software' by client '/System/Library/PrivateFrameworks/PackageKit.framework/Versions/A/Resources/in stalld' [235] for authorization created by '/System/Library/CoreServices/Software Update.app' [567]

Problem elimination:
* I don't think this is a router-related issue: I have downloaded and installed other softwares outside App Store successfully
* As said, I don't think this has anything to do with Firewall or Virus settings
* Nor has this anything to do with /var/folders as far as I can tell
What I've tried so far:
* Repaired disk permissions several times
* Rebooted
* Restarted App Store
* Following one advise found on the net, I deleted preflight.pfpkg just in case
* All the time I have made sure my OS has the most recent Software Updates installed (most of them downloaded successfully, while with Safari and OS 10.7.5. I had to try several times before they were downloaded succesfully)
I just reinstalled my OS X Lion, only to use it to jump on to Mountain Lion - so I am pending my migration until ML is installed. I would like to fix this soon, since I'd like to get the migration done and my real work started. I would really appreciate your help.
I'm not very adept at using Console or Terminal to troubleshoot, so if someone could guide me through the problem identification, that would be great. Unless someone already knows exactly what's going wrong and can show me a working solution - that'd save my day!
Thanks!

In cases like this, if you have an Apple store near by, they will most likely install the OS free of charge for you, if you can't bring your Apple ID along to prove you've paid for it.
Would that work out for you?

10.6.8 and Lion wifi problem

hello,
I am trying to use my mac for one week...... ;(
everything was fine until update to 10.6.8... wifi problem as many of you already know. tried to update to lion, same problem. Got back to 10.6 and then update to 10.6.8 using software update... then formatted again, fresh install 10.6 update to 10.6.8 using combo update, same problem.
tried to delete firewall file, turned off ipv6, changed security of my router from wpa2 to wpa, tried different channels, reset SMC and RAM, all the solutions we can research... all the same
now I am on 10.6.7 and seems i still has the problem happening....
hello apple, more than a month and no solution yet????
I've read somewhere a new procedure that consists in update to 10.6.8 and before restart do some procedures.... but I can't find it anymore, any help?
I guess that solution is the only one remaining I did not try yet.
thanks and regards,
raul

well, it's caused by software only, there is nothing wrong with airport hardware
hard to believe, it's like windows old time sake, loosing precious days fighting with a computer...
too bad apple

Mountain Lion download problem

I have been trying to download Mountain Lion for about 5 hours now and I keep getting errors saying the download cannot be completed. The last error I recieved was The download could not be completed becasue of a Hash Mismatch Error.
A download of about 4GB of data on my Internet Connection would usually take about 1 hour.
If I do get to succesfully download the Installer will the Installation begin automatically or is it started manually. I would prefer manually so I can make a backup copy first.

I am on a Late 2011 13' Macbook Pro, OsX 10.7.5

Contacted Apple Store Tech support requesting a solution. I received a reply from a gentleman telling me his area of expertise and that this problems didn't fit in his area of expertise and suggested I look on online forums and the like for a solution!!
All I have found out is this is a very common problem
Thanks for http://www.apple.com/support/mac/app-store/contact.html?form=account. Have not received a reply from Apple after 48 Hours.
I have tried:
Logging out and back onto the Online Store
Deleting the Apple Store cache on my HD
Connecting via an Ethernet cable instead of WI-FI
Using my iPhone 3G Data, teathered
Connecting via a totally different network
Restarting, restarting, restarting...
Nothing has worked. And still no solutions from Apple. I kinda of thought they might have suggested I go into a real Apple store and have them put a copy on my Mac or something.
