Lion WiFi Connection Problem

It is driving me insane. And how ironic that it dropped the connection as I was trying to reply to this thread! I've nevr evr had any problems prior to installing Lion. And what is irritating me the most is that I don't seem to be seeing an acknowledgement that there is a problem when clearly there is! Aaaarrggh!

There clearly is a problem that is affecting very many users and Apple cannot ignore this. With Snow Leopard the wifi was very stable and now it is very unpredictable. Let's hope for a fix soon otherwise many will be asking for a refund on the basis it is not fit for purpose. On another point I have noticed that the magic mouse cursor now moves to another part of the screen all by itself. A minor irritation that didn't happen with SL. On balance I do like the new features but hope the issues are soon resolved.

Hi,

I tryed everything and nothing work. More time in some cases without drop but drop.

I assume that Mac have to solve this issue ASAP or I have to demand to cover my losses.

You can do this or do that but I insist nothing work like we have in snow leopard: never have any problem.

Regards

Its not just to beat on apple over it but also a place to share possible solutions,information and articles regarding the issue.

Good page.

I too have had the problem with Lion wifi, on THREE separate computers.

On all three, I'm lucky to stay connected to the internet for more than a minute.

My router is an airport extreme, so I'm using all apple gear.

When I reinstalled snow leopard on my macbook air, the problem went away - so I'm sure this is a Lion problem.

HOW DID APPLE NOT CATCH THIS PROBELM BEFORE RELEASING LION!!!

It's not like this is an off-beat kind of thing to check out.

MAKING SURE A COMPUTER CAN PROPERLY CONNECT TO THE INTERNET IS GROUND ZERO WHEN TESTING A NEW OPERATING SYSTEM!

I just don't get it.

To be sure, that's never been Apple's M-O.

They almost never (antennagate being an exception) talk about bugs or problems publically. Instead, they'll hopefully fix it in the next .1 release.

For me, I'll let the fanboys enjoy all the superfluous Lion eye-candy. Me, I'm back on an OS that 'just works" - Snow Leopard.

My issues with wifi quit when I switched to Lion actually, however I had this issue with SL. I suggest trying to run all software updates. What hasn't been fixed by those should be fixed in 10.7.2 which will be released soon. Until then I would probably suggest turning airport off, then turning it back on. This generally seems to resolve any major issues.

Of course you can do this through terminal as well by running an ifconfig en1 dn then ifconfig en1 up.

Just to follow up my post of several days ago, following the upgrade to Lion I was experiencing the dropped wifi problems, in my very non technical way I followed the simple suggestions first, I moved my wifi connection to the top of the available list and performed the SMC reset, it all worked straight after and I am pleased to report that over the last 4 days ( fingers crossed ! ) everything has worked just as it did before the upgrade, I have also tried taking the computer to a local coffee shop, again no problems there or on my return home when I reconnected to my home connection.

I have observed behavior with wi-fi vis-a-vis Time Machine backups. If I open my MBA from sleep and it does not immediately back up, then I have no trouble getting a good wi-fi connection. If my laptop begins to back up to Time Machine, I will not be able to get a wi-fi link until I stop the backup. As soon as the backup is stopped, I get an immediate wi-fi connection. (I have not had the patience to sit and wait for the backup to complete and see what happens.)

I never noticed this behavior in Snow Lion. Anyone have the same experience, or ideas about this?

I do agree to some degree the situation is made worse by doing a lot of tasks or extra bandwidth, this was never an issue on SL, but since moving to Lion, I get extremely long hangs/no loads/delays to load any page when anything using a few resources are occuring. I also notice that Safari 5.1 seems to be the worse affected, if you get a no internet connection with Safari, try loading Firefox for example to access a default web page (yahoo etc). If you are using a N router, flip it to B&G mode first, load a page to yahoo or google for example then leave it for a while minimised, come back and reload the page, if you get a page not found, and keep trying, chances are you will get the error page to keep re-occuring or even display a local drive mapping. However if you try and go to the same Page using Firefox, it tends to wake up the wifi-card and display the page, once its done, Safari then tends to reload fine (although slower initially). Well that is what is happening in my instance

I am having a simir robl MBP wich was until last night happily working with a wifi connex to iphone personal hotspot. Out of the blue it decided it could no longer see the connex. I enabled the connex via Bletooth and it works again. Yes m in Lion!!

not sure what has happened

It's weird. After the initial release of Lion and I ran into these Wi-Fi issues I was told by a Genius to switch my Airport Express to G-Only and to one specific Channel. That worked well up until a few days ago. Now I'm forced to try out various variants of B/G, G-Only, Broadcast Strength, Multicast Rate and Channel.

Right now....it's weirdly acting okay. I'm 24 on the Multcast Rate, 100% output. Channel Automatic and G-Only. But as others have noticed...this problem seems to appear when bandwidth is high. I've noticed it when on YouTube or NetFlix.

Out of curiosity I ran an "automatic test" on Testmy.net. When the test got the 15MB download the Wi-Fi Dropped.

Sure hope they fix this soon.

Problem:

------------

My problem is that the wifi does connect to the access point and gets a legitimate IP address but I am not able to get onto the internet. Safari, itune etc don't allow me to access internet based locations.

Observations:

-------------------

(1) Connecting via ethernet fixes access to internet... including wifi connectivity (even when ethernet is disconnected)

(2) once systen is restarted / rebooted, the original wifi issue comes back

Solution: (with help of Apple's trial and error).

------------

System Preference -> Network -> Change Location (from whatever is current) to any other or newly defined location... Wifi back to operational state (until next reboot)

as i explained on page 12 of this thread, i have the same problem with waking from sleep and time machine backups. i've let it back up two times since lion. it took well over 20 hours each time... it deosn't get any faster (it never took that long with snow leopard) and it still causes the internet to not connect if you wake from sleep with a time machine backup in progress.

If I'm not mistaken we are mostly in agreement: wifi worked better (properly) with Snow Leopard, it does not work as well with Lion, and in most cases the only "variable" is the OS upgrade. Apple needs to sort this, various hokus-pokus may help some lucky people in some specific situations, but the clear truth is Apple screwed up the wireless networking with Lion.

This is exactly the situation for me. We have a bog-standard Netgear home router. Doesn't matter if it's G, N, or Z - it's bog-standard and it worked, the Macbook Pro was fine with it, my PC laptops always were fine with it (and still are). At home, the MBP always sits on the kitchen table in the same place (it hasn't moved); the router sits on a bookshelf in the sitting room (it too hasn't moved); my PC laptops (we have 2) both worked before, both still work, anywhere in the house. And previously if we DID move the MBP to another room, it too worked.

I am no computer technician, but I am capable of basic logic. Prior to the upgrade to Lion the wireless worked flawlessly on the MBP. From the first time I ever used Lion, and ever since, the wireless has not worked properly (not to mention printer drivers which don't work, Time Machine-compatible drives which are no longer compatible, and a multitude of other things which used to work find but now don't). Like others I was sucked-in by the snazzy marketing promo video (gestures, full screen, etc) and now have a machine that is verging on unusable, not to mention a seriously p****d-off wife (it's her MBP!!).

I can only echo the comments of others. We expect this from Microsoft. We are used to MUCH better from Apple. I presume the commercial imperative to get this out to sell new MBAs is what drove a clearly poorly-tested, seriously-flawed OS to be launched by a Company from whom we do not expect such behaviour. Hopefully (a) salutory lesson learned by Apple, although may be wishful thinking on my part, and (b) more important hope they launch upgrade soon which resolves these issues.

Meanwhile I will check out of this conversation since, after 22 pages, I think it's time to acknowledge this is not something users can fix for ourselves.
