Lion WiFi Connection Problem

Same problem. No wi-fi post Lion upgrade. Spent hours on phone with apple support and they have been unable to fix the issue. I can connect if I restart the machine in recover mode. Have tried every fix found on the forums to no avail. Apple engineers came back with a suggestion that I uninstall vmFusion. That didn't work. Currently awaiting a new suggestion from Apple engineers. Can get by another day or two before returning to snow leopard to see if they can find the fix.

I suggest to anyone wondering if they should upgrade to Lion that they wait. Big bug in the system here.

I am having these issues on a 2010 iMac 5.

At least I'm not the only one with problems, right? Reminds me of when I became an early adopter of MobileMe.

Had no problems with my Macbook wifi connections for over three years. Installed LIon and I can only stay connected for very short periods at most. I've tried som eof the things posted here and the only thing that really gets me back is shutting my router down and restarting everything. I spent about an hour with Apple support on the phone and was finally told to talk with my ISP. I have a desktop windows PC that works great over my WIFI connection and My kids have two Ipads and a Macbook running snow leopard and they work fine. Needless to say I am very disappointed with Apple and have learned a lesson: Don't be an early adopter. Apple needs to address this quickly.

I'm in the same boat with wifi issues. MBP 2008 model. Worked fine under SL, but patchy performance under Lion. Some sites in Safari are fast, some fail to load, most just sit there with nothing on the screen.

Seems that most of the macs that are having the issues are around the 2008/9/10 time period. I wonder if they all have the same wifi/bluetooth card. Chances are Apple may have botched the wifi driver for this particular card with Lion.

I have a Macbook2,1 (mid 2007) and a netgear WGT624 v3 router. With 10.6, most days I had to reboot the router because the laptop would fail to connect. I spent lots of time troubleshooting it and nothing I changed on either the laptop or the router seemed to resolve the problem.

With 10.7, it too fails about every day or so but the difference now is that rebooting the router doesn't resolve it. I need to restart my laptop. With 10.7 I get a lovely error window whereas with 10.6 it just failed.

I'm thinking of buying a new modern day router, mine is a few years old, but I'm not convinced that'll help.

Has anyone narrowed down which routers, in combination with 10.7, may be contributing to this failing?

After hours of unsuccessful troubleshooting I just went "back to Mac (OS X Snow Leopard)" yesterday. Now everything works fine again and I`m just gonna wait for the first two or three Lion-Updates an then have a look at it again...

Thank you for this; I am convinced this is a bug in Lion and has nothing to do with system parameters.

Accordingly, I have taken your advice and submitted a 'bug report' using the 'online feedback submission form' (not wanting to claim 'developer' status, when I'm really just an ordinary 'customer' - and who said 'the customer is king'?)

Currently I'm working on the theory that if I don't touch the machine for a few minutes after waking, the Wi-Fi stabilises and I can reconnect without the 'diagnostics' procedure.

I will provide feedback when I'm sure about this, but I'm still certain there IS a bug and I'm amazed Apple haven't acknowledged and addressed it!!! (Their telephone support service seems useless in this context - they won't EVER admit there could be a real problem!)

This, unfortunately is very reminiscent of other electronics outfits I've dealt with over the years- Microsoft, HP, Dell and TomTom spring immediately to mind. Now Apple seem to have joined the ranks of the 'mediocre' as well. Very, very sad....

Continuing from my earlier posting:-

I can now confirm that if I wake the machine, wait at least two minutes before touching it, then launch Safari, it seems OK. Anything less than two minutes is not enough!

One of the things I loved about Snow Leopard, after years of struggling with other systems, was the ability to access the web instantaneously; my new MacBook Pro is now worse in this respect than my (very) old Hewlett Packard desktop!!

Again, I'm surprised at the lack of reaction from Apple - for many people the whole raison d'être of a laptop is to access the internet quickly and reliably. Why don't they issue a list of known problems, in priority order - and explain how they propose to deal with them?

Special thanks to 'nipper123' for your inspirational postings.....

Same problem here. Will wait a week for a fix and then reformat and go back to Snow Leopard. I'm on a brand new iMac, it's only a few months old, so it's definitely nothing to do with outdated hardware. Very frustrating!

SAFARI, that browser that has ALWAYS been troublesome IS the issue for this problem. In LION that disaster of a browser is plagued with even more ridiculous issues. You cannot delete it. You cannot disconnect if from all in the OS it is tied to.

Apple has about 24 hours to put out a fix before this is a headline EVERYWHERE and stifles sales.

I had to revert too.

Wireless worked after install, used it to update all my probrams in the mac store. even installed Abobe and all of its updates. shut down for the night,then no wireless at all.

I click on the "turn on wireless" nothing.

Went to the apple store and became their gunipig for 3 hours, finally they decided what i needed was a fresh install. Which they did, i got home all was good of hours. Again installed all my stuff and shut down for the night.

next morning no wireless again. This stinks. I am new to apple and feel like this is just typical of a Windows problem.

For all who have problems: it would be interresting to see if the problem persists when you change to another wifi network. For myself: I experience problems on one of my home networks (i have two), the one that has a Airport Express connected to it. On my other network with Cisco gear and at my office network with Juniper gear I have no problems whatsoever.

It might help Apple to troubleshoot (I'm sure they are reading this thread) if you can answer these two questions:

- when experiencing problems, what make/model of wifi router are you connected to?

- if you switch to other wifi networks with another make/model wifi router/access-point (please also specify), does the problem persists?

I would feel a lot better if Apple was acknowledging the problem. Without that we don't know whether it will ever be fixed, which makes me unsure whether to switch back to Snow Leopard or not. If they haven't acknowledged it by the end of the week I'll likely reformat and go back.

I want a refund.

I have a 27" imac under SL I had no wi-fi issues, under Lion, at first drop outs every 5 or 10 minutes, I tired numerous solutions offered and no result now I am flat out keep a connection open for 30 seconds.

Wi-Fi is an essential part of an OS these days. No internet on my imac it may as well be a shinny paperweight.

I was a convert and said I would never go back to Windows but no wifi is inexcusable it up such an important aspect of an OS they call this an upgrade. I thought apple was not following windows in more glitz more glamour less stable with every new OS, to release this product without adequate just shows apple is going the way of windows.

I will be demanding a disk for the OS patch to fix this because there is no way I could download on my wi-fi connection.

Keep posting if you have this problem.

Posted from my Windows 7 PC 😟

As per my previous post WiFi does not restart after sleep on a 2010 i7 8GB SSD iMac with Netgear WNDR3700.

OK back to square one and did a clean install of Lion 10.7. Took a long time to get back to where I started from - NO restart of WiFi following sleep.

We are waiting...APPLE!

Your want a refund and demand a disc to update because you won't be able to... Even though your able to use another computer? :)

I think everyone who isn't happy should downgrade to sl till 10.7.1 comes out which will b soon.. Or deal with not being able to use facey for a few days. Sheesh. Smell the roses everyone.

And before I get messages back about its affecting business etc. It affects me too. But be proactive about it and either downgrade. Or wait. :)
