Wi-fi connection problem with 10.7.2

I've been through these forums for the past week, and while I recognise my problem in other posts, I haven't been able to fix it. I have a 2011 MBP and had no problems until I updated to 10.7.2. I have no Internet at home and only connect at my public library. It's not the router--non Mac computers can connect, as well as phones and iPads. I'm on my iPhone right now, in fact. I've asked a few other Mac users, and the ones who updated Lion are all having problems. My MBP can read all wi-fi hotspots. I am connected with full bars. But the authorisation window that allows you to sign in is stuck in load.


The people who work IT at the library have no experience with Macs. I talked a librarian into letting me connect my laptop to their Ethernet, and my Dropbox synced, but pages still wouldn't load. Something is definitely wrong on my software side. There's something, like a firewall?, blocking my applications from connecting to the wi-fi. I use Chrome, and when I tried to launch Safari for testing, it wouldn't, and I had to force quit. iTunes won't connect either.


Things I have tried: restarting, reordering network preferences, deleting keychains, setting IPv6 to link-local, adding 8.8.8.8 as a DNS, reseting PRAM and SMC, repairing disk permissions, and a lot of other fixes, which I'm forgetting now, that seemed to work for other people on this forum. I've looked, but none of the system configuration files it's been suggested to delete are on my computer. I don't even have system configuration film in library/preferences, so maybe that's a problem?


Any help is truly appreciated.

MacBook Pro, Mac OS X (10.7.2), 2.4 GHz Intel Core 2 Duo, 4GB RAM

I don't know if this will work for everybody, but I was having the same problem of no connection via wi-fi.

What I did to fix the problem was Network Preferences > Location > Edit Location


Add a new location; restart wi-fi. Should hopefully work after that. It's worked for me in one location thus far; I'll be going to try it elsewhere.


You might also want to add 4.2.2.1, 4.2.2.2 to your DNS servers as well.

I am having the same problem with my new MacBook Pro (2011) and i try to connect to my high school's wifi and it does not even show the login page. I used time machine to revert it to 10.7.1 but i wanted to use the iCloud fucitionality in 10.7.2 so any help would be appreciated.


also there was a firmware update for the MacBook Pro after that so if anyone downloaded both can you tell me if it works after

Same problem there but I found a (partial) solution using Opera browser.

Install Opera for Mac (my Wifi network at home works perfectly) on your laptop.

When you are at the library (or elsewhere with a public wifi hotspot access), connect to your favorite network.

Then launch Opera with the Turbo Mode enabled.

Refresh the page and, normally, you can access to your login page.


According to me, it seems to be an issue with websites and/or applications using SSL protocol.


Hope it helps!

All, I have a brand new iMac with an Atheros chipset on the Airport card. Somewhere on Diascussions there's a post on incompatibilities between SOME routers and this card with its version 4.x.x driver, when on N-band of 802.11 WiFi. I am not tech, but simply disabled N-band within the WiFi router, and now it works. Also, Apple branded WiFi routers do not have this problem. Please search Atheros and have a look, or disable N-band for a try. The N-band trick was told by my ISP "who are aware of the problem and work with Apple and cannot say anything more". Sorry.

Hope this helps.

I have a Macbook Pro OSX Lion 10.7 that is about 5 months old. I'm new to Apple products (Ipad 2, Iphones, MacBook) but just learned that when my stmp & imap had a problem with my AOL mail, that my files were corrupt. When you go into library the files are supposedly hidden so as not to allow the user access to delete what they may think are "unnecessary". Seems as if Apple has this problem with their customers.....

I just upgrade to 10.7.2.


I already had wifi dropped connections with 10.7.1 ever since I bought my new iMac in August 2011. It has never remembered my wireless network. I have always had to manually enter the WEP key.


Now with 10.7.2 I cannot enter the WEP key at all, because when I select my network I am told "Cannot connect, connection timed out".


I have to go into Network and then use Assist to select my network and then enter the WEP key. When I do this it tells me "incorrect WEP key. Cannot connect" - but it does connect as the airport icon in the toolbar shows a connection.


It is infuriating and after searching nearly all the forums I see that this issue is rife. The only consolation is that I am not alone, many others have this issue. But it is a really bad state of affairs that so many new and nearly new iMacs/MBPs are suffering from this.


I have a MBP with Snow Leopard and have NO issues connecting wirelessly.
