Mountain lion wifi problems

I can totally understand this frustration. I updated to 10.8.2 hoping that this would fix the problem but it got worst. Not only am I loosing connectivity but Safari would crash or become unresponsive after loosing the Wifi connectivity. I was told a while back ago by technical support from Apple (after paying $49) for this assistance that nothing can be done and that 10.8.2 would solve the issue. But it didn't. So, what I did, like someone suggested, I purchased a new router, a Dual Band (2.4 & 5ghz) wireless-n router, try it and its been 4 days now, it seems fine. No lost connection and no crashes so far....my fingers crossed!!

Now, is Apple going to refund the cost for the router, NO. Would I be able to get the $19.99 back for purchasing ML? NO! I am screwed anyway.

I had another thread here, "Did Apple rushed the 10.8.2 update?" - I think they did. Is Apple getting to be "Too successful to care?"...... I had better chance of stable experience with Microsoft windows than Mac OS lately...

Apple, hope you improve. Otherwise I may decide to go back to Windows, not that you care...

I bought a Retina MacBook Pro in the end of August so it came with Mountain Lion preinstalled. I had two major issues with it. Wake up from sleep from was very slow, sometimes 10 seconds (not from deep sleep).

The other one was a very big problem with connecting to wifi networks. The strange thing was that in the beginning it couldn't connect to my own router or if it could then there were regular drop outs and slow downs in internet speed. After a while (without any kinds of update) the connection problem gone with my own router but the speed was still quite unreliable. Still I couldn't connect to the majority of routers when I was on the road. Usually it said "connection timed out". To be honest I can't remember one wifi network from the last two months which I could connect to except my home router. I did extensive testing, one of the most interesting problems was my neighbor's router (the most popular Linksys WRT54G) which I couldn't connect at all, it didn't accept the given password even if my other devices could connect flawlessly.

Of course since then I downgraded to OS X 10.7.5, Lion and now everything works fine but it's totally insane, I cannot even imagine what kind of bug it can be in Mountain Lion which renders the OS absolutely unusable and something that Apple don't work out exclusively. Maybe not everyone has these problems even if all Retina and standard MacBooks have the same networking hardware. It must be a joke.

I have been having the same problem. I have a two year old iMac. Ever since I installed Mountain Lion, I cannot maintain a consistent wifi connection. I have tried everything suggested. The only thing that works is if I go into the system configuration folder and delete all of the the network files and restart. This give me connection for a few minutes and then it goes out. My iMac doesn't show any other networks. Yesterday, I took it to an apple store. After twenty minutes or so, they told me my airport card needed to be replaced. This doesn't seem right to me. Has anyone else been told the same thing? I find it awfully coincidental that my wifi card needs to be replaced at exactly the same time I upgraded to Mountain Lion. I really don't want to shell out $100 for them to replace the wifi card. Any help would be greatly appreciated. Thank you.

It seems like I've heard every 'solution' I could imagine from other people's experiences. If Apple is aware of the problem we are all having, then they are still trying to figure it out.

I imagine, as an Apple Genius, the worst thing you can do is appear uncertain or say, "I don't know". But if Apple is aware of our problem and doesn't have a solution or reassurance that they're working on one, then its irresponsible business practice to confidently hand out "solutions" which are probably expensive, and may or may not solve the problem. I feel your pain.

Hallo,

since the upgrade from Lion to Mointain Lion it's get really worse with the wifi problems. It's start with the upgrade to Mointain Lion.

At least once a day the MacBook Pro lost the wifi connection, it's doesent matter which wifi network is used and than the only method to get wifi connection back is the Reboot.

I really try every hint from the www but nothing solved the problem.

The problem must be ML the only thing changed so far in that time on my side.

Lion was not really an improvement, so not an option. If their is no solution I have to Fallback to Snow Leo. The last stable Apple like OS Version.

I have had this problem for such a long time now, ever since Snow Leopard and I have just installed 10.8.2. In order to load a page I have to renew the DHCP lease every time. I was hoping that the latest upgrade would sort this out but absolutely nothing has changed...

It happens in Chrome, Firefox and on Safari... I've tried all the suggestions and even set the MTU to 1453 but nothing makes a difference..

Can anyone give another suggestion for a fix?? Help!!!

10.8.2 did not fix this problem for me one iota. I have a connection to the router and WIFI signal is great and NO INTERNET CONNECTION. This occurs at random intervals. Have to disable and reenable WIFI. Im at a loss what could be causing this. It is definately not on the routers end because others devices on the network dont suffer from this. Why oh why did I follow the prompt to update Snow Leopard to 10.8 and then Mountain Lion its been nothing but aggravation since. Never had connectivity or battery problems now thats all I have. Also running a speedtest on Macbook will yeild a significantly lower score than on a device right next to it on the same network 13Mbps to 1.8Mbps Etherenet cable into router over 30Mbps. As well as not being able to stream audio without constant buffering leads me to believe there is a glitch in the coding of this OS.

I went back to reinstall the Airport utility but went for the 5.2 version. This causes Time Cap to reset back to the Apple default settings. After this Appel Time Cap worked just fine.

I found the older software on the Apple website under Airport Utility 5.3

Good luck!

Last patch did not fix the issue I have with my Imac.

October the 23rd, I'll install W8 on a new dual boot!

I get 2 MB pro, 3 iphones (3GS,4, 4S) with no WIFI issues while my Imac is no more able to access the web with this new OS!

Obviously, APPLE does not care about this major issue!

Enough is enough! Let's say I will create a dual boot using the new W8 on the 23rd of october! and bye bye APPLE!

I'll do the same on the 2 others computers (MB pro) and will go to Samsung for my phones ASAP!

Ostrich is a good strategy Mr Tim Cook!

It's your choice!

Same problem here.

New macbook pro 13 inch. No problems with wifi 10.8.1

Updated to 10.8.2. wifi is connected but no internet

When i turn wifi off and on it works for a couple of minutes.

Is there a way to get back to 10.8.1 ?

Please Apple fix the Wifi issue!

I had issues with both wired and wireless networking stopping altogether a short while after upgrading to ML.

It was temperamental at first, and a reboot would clear it. Then it stopped working altogether.

Turning off the firewall temporarily (in the Security & Privacy prefpane) resolved this, and networking has been working ever since (now with the firewall back on). I'm guessing it was my ipfw rulebase blocking DHCP.

(I appreciate that this may be unrelated to the wireless problems above, but am mentioning it just in case it’s helpful to anyone).

Started having wifi issues after an update last night. Shades of Microsoft incompetence here. I am wrining this on my Debian desktop, apple is going down the tubes with these poor qualty updates. Have tried all the normal fixesI suppose I will have to wait for the next update to fix the last update which fixed the previous one bla bla bla.

I had more or less stabilized the situation with ML WIFI issues by going to reduced MTU, changing from WEP128 to WPA2, moving to fixed IP instead of HCP and disabling power saving....

Now it seams that he "supplementary ML update" that I applied yesterday evening has again broken everything. I am not at home but the kids are calling me as Internet is broken and can not be reestablish after the "usual for ML" reboot procedure that they got used to... :(

I have WiFi problems in my MBP 2007 after installing 10.8.2. The internet connection usually lasts 2-5 minutes and then it crashes. I need to switch off the airport and then on again or to renew DCHP Lease from network preferences.

Does anyone have a solution to this??!!!

Please help!!!

It's an ongoing problem for me since I installed ML 2+ months ago. Still haven't found a solution. My router is still pretty new, and I've been through a couple Genius appointments, to reinstall ML and try to replicate issue. They couldn't, so as far as Apple is concerned, the problem doesn't exist, but sure, they'll offer to sell me a product to solve my problem. Why am I spending money to fix their broken OS, which I already paid for, and deeply regret?

Genius thought maybe bringing in an Airport Express might help ML WiFi handshake with the network (which worked fine on SL).

Plugged in Airport Express, and I get a message informing me of "unexpected error" occuring. The thing doesn't even work. Still resetting WiFi every three minutes.

Right on, Apple. Right on.
