fixed : 10.7.5 refusing to see the Atheros AR9280

I must admit the title might be a little misleading, since I have not had anyone claiming problems like the “WiFi: no hardware installed”-error with the Atheros AR9280 AirPort-card and MacOSX 10.7.5 yet, but still…

…that is probably due to the fact that the MacOSX 10.7.5 updater doesn’t overwrite the IO80211Family.kext system extension. So if you are upgrading from an earlier version of MacOSX 10.7 “Lion” which you had already ‘patched’ for use with the Atheros AR9280, you won’t get any (new) issues…

Anyway…

If you do get the “WiFi: no hardware installed”-error after upgrading to MacOSX 10.7.5 (e.g. from MacOSX 10.6 “Snow Leopard” or earlier), you can just do the same ‘patch’ of reinstalling the old IO80211Family.kext system extension. Instructions for doing so can be found here :

fixed : add sound to Screen Sharing

Question :

I am using OSX’s built-in Screen Sharing option to control the Mac in our living room, when I am in another room with my MacBook – it’s great !

But sometimes I would like to listen to a video or a music track that I’m playing on my ‘living room Mac’ and Screen Sharing doesn’t support that…

What can I do ?

 

Answer :

There’s a simple and FREE utility that will help you out on this one : Soundfly

Just download and install Soundfly on both Macs and then run “Soundfly” on the ‘sound sending Mac’, and “Soundfly Receiver” on the ‘listening Mac’… it’s that simple…

You can download Soundfly here :

UPDATE : the latest version can be downloaded here :

info : setting up Back To My Mac through a TG712 modem-router

Question :

How do I setup my Thomson TG712 modem-router to allow me to use the the Back To My Mac function of my Macs ?

Answer :

Here’s how to turn on Back To My Mac when you have a TG712 modem-router :

– on your Mac, go to Apple —> System Preferences —> iCloud

– then put a check mark at “Back To My Mac” to turn the service on

– if there’s a “More…”-botton click it, just for your information ; if a warning is listed, read it, keep it in mind, and don’t bother…

– then open Safari (or any other internet browser) on your Mac, and type the web based control panel’s IP-address of your router-modem as the URL ; for the TG712 router- modem, the IP-address is 192.168.1.254

– in the web based control panel, go to “Toolbox” (in the menu on the left) –> “Games & Apps Sharing” (in the menu on the left)

– then in the middle of the page, at the bottom, from the “Choose a task…” list, click on “Add a game or application to a local networking device” (the first link in the list)

– in the page that opens, put check marks both at “Use UPnP:” and “Use extended security:”

– and set the “Game or App”-dial (the one that is initially at “ABC (Another Bittorent Client)”) to “Back To My Mac”

– set the “Device”-dial to your Mac (which is the Mac that you would like to use with Back To My Mac, so probably your Mac-server or desktop-Mac)

– just to be able to trace possible errors, put a check mark at “Logging”

– then click on the “Add”-button

– wait for the router-modem to restart

– logout by closing the browser-page with the web based control panel on it

Now you should be able to log into your (home) Mac, when being at a remote location (if there’s internet connection there…)

fixed : quickly share your Mac’s internet connection to your iPad

Question :

I just got myself a WiFi-only iPad, but I have no WiFi reception in my living room (that’s why my Mac in my living room is connected to my network through an Ethernet/UTP-cable). Is there an easy way to get internet connection on my iPad in my living room ?

Answer :

Yes, there is.

Your Mac can share it’s internet connection from one of it’s internal network-connections to another. So from Ethernet to WiFi in your case.

To get it working is easy :

– turn on your Mac (if your Mac isn’t running, this won’t work)

– go to System Preferences (under the Apple-dropdown menu in the upper left corner of the desktop/Finder-menu)

– in the window that opens, click on “Sharing”

– in the screen that opens, click on “Internet Sharing” in the list on the left

– then, on the right, select your incoming network/internet connection at “Share your connection from:” (so, in this case select “Ethernet” there)

– and then select your outgoing internet connection at “To computers using:” (so, in this case put a check mark at “Wi-Fi”)

– if you want your shared internet to be password protected, click on the “Wi-Fi Options…”-button and choose your preferred network name, the preferred password protection protocol and your preferred password. If you don’t need protection, just leave everything as-is.

– then put a check-mark at “Internet Sharing” in the list on the left and quit System Preferences

– now you will see that your AirPort/WiFi-pie icon in the upper right of the desktop / finder-menu has turned into a new icon with an arrow pointing upward.

– then, on your iPad (or iPhone or any other WiF-connectable device) go to Settings, click on WiFi and select your new local WiFi-network

– done ! enjoy !

Note : you’ve just turned your Mac into a local WiFi-router (also), so remember that your Mac has to be switched on to sustain the WiFi-network connection

tip : surfing the internet while in Rescue Mode

Question : My Mac’s network connection is messed up, and I need to download software to update of fix this – what can I do ?

Answer : Since OSX 10.7 Lion, there is an easy way to do this if your networking-problem is software-related, not broken hardware.*

1- restart with the ‘CMD’ + ‘R’ keys pressed (‘Rescue Mode’)

2- then use Safari (listed as ‘online help’) to go online

3- go into Safari’s preferences and change the download folder to a USB-stick or external hard drive (just make sure it has enough space to hold the file you’re going to download)

4- go to the site you need to get the download from, and download

5- restart your Mac normally and install the download from within OSX

* = in Rescue Mode you will be able to connect to the network (and the internet) both though a UTP/Ethernet-cable or WiFi/AirPort-wireless, so only if BOTH your Ethernet-hardware card AND your AirPort-hardware card are broken, this will not work…

BEWARE ! : FBI warns not to upgrade software through free-WiFi !

Posted on by

The FBI has reported that users of ‘out-of-home-WiFi’ (free-WiFi hotspots, hotel WiFi, etc.) have become infected with malware, while upgrading ‘a widely used software product’.

http://www.fbi.gov/scams-safety/e-scams

The original report states :

“Recently, there have been instances of travelers’ laptops being infected with malicious software while using hotel Internet connections. In these instances, the traveler was attempting to set up the hotel room Internet connection and was presented with a pop-up window notifying the user to update a widely used software product. If the user clicked to accept and install the update, malicious software was installed on the laptop. The pop-up window appeared to be offering a routine update to a legitimate software product for which updates are frequently available.”

Even though the software product is not mentioned by name, it is good to inform you that one of the most common software products using this type of upgrades is Adobe Flash… so watch out when upgrading Adobe Flash (and any other software upgrade that is offered) when you are not on your own private WiFi-network.

So… here are some useful guidelines regarding software updates while traveling :

1- if you can do without upgrading, don’t upgrade while traveling ; wait until you’re back home on your own trusted WiFi-network

2- if you really need to upgrade, take these precautions : when you are prompted to upgrade any software while on an ‘out-of-home-WiFi’-network, click to close the pop-up window that is urging you to upgrade. Then either use OSX’s built-in “Software Update…” feature, or open the (Mac) App Store to download your updates from there, or manually type the URL of the known software-maker and download the software update directly form their site (after having double checked that your installed version is not the latest one).

Note : in the case of of the Adobe Flash browser plugin, the software-maker’s website is Adobe.com
