MacBook Air :: 13" (mid 2011) Wifi: No Hardware Installed?
Mar 24, 2012
I bought MBA 13'' mid 2011 about 3 weeks ago in Houston,TX. Today in the morning, after reboot i cannot connect to any Wi-Fi network, because i see wi-fi icon disabled and it is shows: "Wi-Fi: No hardware installed". My MBA running on 10.7.3 MacOs. I've already tried:
1). Remove all setting for network;
2). Reset SMC
3). Reset PRAM;
4). Boot in Windows via Bootcamp (wifi adapter cannot be found as well);
5). Rebooted about 10-15 times;
6). Run Wi-Fi diagnostics and it is hanged up.Â

I successfully connected to their Wi-Fi system. After a few days a strange problem starting occurring once in a while and I solved it by just restarting the computer, now however, it is stuck with this problem and my temporary solution does not work anymore. The laptop will not connect to the internet and up in the menu bar I see the 'connection meter' all greyed out with a white cross over it. If i click on it it says 'Wi-Fi: No hardware installed'. Run a program called EtreCheck to get a report on the system. This has been posted below. I recently did a complete reinstallation of the system after formatting it. This was because I could not install Windows via Bootcamp, which I have now successfully installed.

I have a MacBook Air 1st Generation and all of a sudden I have no Wi-Fi connectivity as it displays the above error message ' Wi-Fi: No hardware installed' when I click on the Airport icon. So not only do I not have Wi-Fi connectivity, but even when I connect with and ethernet cable I cannot login to iTunes or the AppStore as it cannot verify my computer.Â

I was at an Apple Store this weekend and playing around with the new MBA. I noticed that they had MS Office 2011 installed already. I checked out the version number and it's 14.0.1, build 101008. Anybody knows if this version is just Apple store, or it'll be an update?

Message Microsoft (MSOffice).app wants to use the font "xxx". This font is not installed. Allow Microsoft(whatever).app to use this font? show in finder, don't allow, allow. happens with all Office apps, runs through entire font library. about 3 months ago this started - not sure what I did to kick it off, but now whenever I try to use a Microsoft Office for Mac 2011 app it runs through the series of fonts and asks me to do something. I can go through one at a time and select 'don't ask me again' and 'allow' or 'don't allow' but I'd rather figure out (and solve) the problem.

I had to replace a dead hard drive on my old 2007 iMac. Now I am unable to install Office 2011 on an iMac that had this version of office before the old HD died. I know there are restrictions on the number of installations. Must I purchase Office 2011 again or is there another legal option?

My 2010 15" MBP has constant Wifi dropouts, sometimes minutes at a time. Sometimes I have to reconnect. Yet it gets 4 bars. My MacBook never had these problems. It's generally slower, too. It's now useless for online video like Hulu. Anyone else seeing this? I wonder whether it's hardware (e.g. they moved the antenna, and/or because of the metal case) or software/drivers? I'm going to submit feedback after input from ya'll.

I have a pretty old Titanium Mac Book that runs OS 10.3.9. It's a moderately slow machine, but still works- and although I realize that it won't be able to stream video or anything, I figure it would work for email, and basic web browsing- But I'm wondering if it's going to be compatible with any new products such as a USB wifi antenna - because the room where I want to use it won't alow for an ethernet connection-  Also, will the old 10.3.9 OS allow me to connect wifi to the newer airport extreme base stations?Â

MacBook. 2Ghz Intel Core Duo. OS Snow Leopard 10.6.6. I'm running a 2006 MacBook with Snow Leopard. A few months back it started dropping wifi connection. Airport would show no connection but would list my network along with others in my building. If I tried to connect with my WPA password it would just time out. At this time I was running Leopard.
Since then I've done a few things.Tried running the Netgear router with no encryption at all (same thing happens). Will lose connection and then time out trying to connect
I've tried the MacBook in a coffee shop with wifi access and at my parents (same NetGear router) and at my new apartment with a horrible Orange Livebox.
Taken the MacBook in to see the genius bar at Glasgow Apple store. Worked fine for them, but I explained it was intermittent but we could not force it to fail. I'm sure if it ran for an hour it would.
At present if I have the MacBook in the living room (where the Livebox router is situated) its fine and wont drop connection. If I walk some 5m to my bedroom it will work for approximately half and hour and then lose it. A few days ago I bought the Snow Leopard upgrade and installed it last night. MacBook runs a hell of a lot faster (yay!) but moving it away from the router and its dead as disco in half an hour.
So to clarify, the MacBook has been tested on 4 wifi networks/ locus with same issue. iPhone, Xbox 360 and PS3 all have no issues with dropping connection no matter where they are in the apartment.
Apartment is a new build and its walls are not made out of lead or kryptonite. Is this a hardware issue rather than software? When updating to Snow Leopard it was an update to the existing OS of Leopard not a clean install.

Installed a new 750GB drive into my MacBookPro 5.1 Couldn't get Winclone to make image so I was forced to start from scratch with a new XP installation.
My MBP is partitioned 25%Mac & 75%XP with bootcamp and I have the old drive in a enclosure connected with a firewire. So all of old files are on the external drive now.
After installing XP I have no internet connection, drivers etc... However if I boot up on the mac side everything works fine. (I cloned the mac os already with Carbon copy).
So can I just copy all my old drivers over to the new drive? If yes how and if no how do I get them installed on the new harddrive. The MBP came with everything preinstalled.

I've just ordered an i5 Mac Mini and while it's destined to be used as a media-centre/ streamer connected to my TV via HDMI, initially I want to hook it up to the display on my 2011 iMac. Can one of you clever bods point me in the direction of what cable I need, and also what do I need to do to the iMac to make it behave as just a monitor? Is it just a matter of plugging in the cables and off I go?

I bought MBA Mid 2011 last March, and I have updated OSX into the last update. Yesterday I connected my MBA into a server to open several spreadsheet files. I succeded. But then - I don't know exactly what's going on - maybe my MBA went off because I turned on the Power sleep at 15 mins. Then I couldn't turn on my MBA. Battery status was about 80%.

I have a Macbook pro 2011 13" which I keeps shutting down constantly. I erase the macintosh hd drive as suggested, also did the ctr, command, option, p and r step and when i try to reinstall the mac os x snow leopard it goes through the process and gets as far as 3 minutes into installation and then shuts down. Even when I try to install the mac os x lion from the disc utilities screen it goes throu the same process and then shuts down and reboots. it constantly shuts down and reboots.Â
