How can I ensue that my WiFi connection is safe/secure

I want to set up my powerbook to use wifi when I'm on the road. How can I ensure that it's secure.
1.25 ghz Powerbook G4 Mac OS X (10.3.9)

Lou E,
Short answer: You really can't. You can, however, choose your relative level of insecurity.
Wireless is inherently less secure than wired.*
Wireless or wired, on the road, you're trusting somebody else's network to carry your data. On or off the road, with wireless you're broadcasting a signal that can be intercepted by any receiver within radio line-of-sight.
There are ways to be more secure and make man-in-the-middle attacks much more difficult: SSH and VPN tunneling come to mind as relatively secure methods for exchanging data.
-Wayne
*When Johnny Cache demonstrated a firmware-level exploit for wireless cards using a Mac, the chorus of condemnation (and defamation and character assassination) was loud and continued unabated until September 21st, when Apple released Airport updates addressing the very same kinds of firmware flaws that Johnny Cache claimed at Black Hat.

How can I fix an intermittent wifi connection with my MacBook laptop

I have experienced intermittent problems with the wifi connection on my MacBook (2006, 10.6.5 OSX) computer and noticed that other users have commented about this same issue. Not sure if the problem revolves around the updates from Apple or my wifi card but I only seem to loose my wifi connection with the MacBook. I have other Apple products, Iphones, Ipads and IMac and they all retain the wifi connection. Additionally, when I connect the internet cable directly to the MacBook, there is no loss of signal and I have no problem connecting to the Internet.
Does anyone have a solution to this problem?

After several unsuccessful attempts to resolve my intermittent wifi connection with a 2006 MacBook (I had service techs from Apple store, PeachMac and Computer Advantage check the intermittent wifi problem in store and they could not recreate this issue), I broke down and bought a new wifi card and installed it myself. The intermittent problem was resolved and my wifi connection works fine everywhere in my home. Ifixit's website has a great video that explains in detail how to remove and install a new wifi card and you will need the right tools and patience. Thanks to everyone that posted comments about this issue because the comments proved helpful in solving my problem.

How can I verify that Firefox Add-0n is safe if author not verified?

I would love some Add-ons from Mozilla.com but when I click on download it says author not verified. How can I be sure it is safe and doesn't contain malware?

When you call DIG_Block_Out, NI-DAQ first downloads your data into the 6534 memory. Only after the download is done (which should happen at about 80 MB/s) it starts outputting data and DIG_Block_Out returns. So it is safe for you to reuse your PC memory buffer as soon as DIG_Block_Out returns.
This is assuming your entire buffer fits in memory. If it doesn't, NI-DAQ will download all the data that fits and start the transfer, and as more 6534 memory becomes available the DMA channel will fill it up.
The 6534 has a 16 sample FIFO and an additional 32 MB of memory for each handshaking group. So for 32-bit transfers you can fit 8 MSamples, for 16-bit transfers you can fit 16 MSamples (per group), and for 8-bit transfers you can fit 32 MSamples (per group) in the 6534
memory.

How can I verify that pop-up upgrades are safe?

I am experiencing occasional pop ups asking that I upgrade Firefox -- ie- download and install the upgrade/update offered with the pop-up. Is this offering legit?

hello robfeimer, first you're right to be careful about such notices, since recently it has become a fairly often used tactic by malicious websites to try to trick users into downloading malware-infested versions of the browser. as a rule of thumb, when you are getting prompted to download and run a .exe file to update firefox, it will be a scam, since firefox handles updates internally...
you can always initiate a check for updates manually in the firefox ''menu > help (?) > about firefox''.

When I am connected to my home wifi, it says I am connected but the 4G icon doesn't go away. How can I make that go away when I am connected?

When I am connected to my home wifi, it says I am connected but the 4G icon doesn't go away. How can I make that go away when I am connected?

When I'm at my home, and on my Wifi, my 4G icon on my LG G2 is still present. No big deal. If the bits can flow via WiFi, that's what they'll do.
You might try (if you really MUST shut off the cellular radio):
Settings, Network Connections and More networks. Select Mobile Networks and uncheck Mobile data and data roaming.
Not sure if that will work - but give it a try.

Hi folks, you might know how to fix this: my wifi shows (no hardware installed) then I went to system preferences and deleted the wifi connection, I went also to system information and I can not see wifi listed on Network, how can I create a new wifi ?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

I want to use my IPOD Classic 160gb for notepad entries in addition to the music and books I listen to. It is set to "Open ITunes when connected to computer" and "manually manage music and videos". How can I do that without losing some of the features

I want to use my IPOD Classic 160gb for notepad entries in addition to the music and books I listen to. It is set to "Open ITunes when connected to computer" and "manually manage music and videos". How can I do that without losing some of the features of those two? I just want to add a feature. Thanks

Settings>Store (or iTunes & App Stores if you are running iOS6)>Apple ID. Tap your son's ID and sign out. Sign in with your ID and password.
You shouldn't lose the music, but if you try to update any apps that you bought with the family ID, you will have to use that password that is linked with that ID in order to update.
Avoid downloading past purchased content with the old ID if you can since you will associate the iPad with the old ID for 90 days and you will lock yourself out of your own, new ID for that period of time. Read more about associated devices in iTunes here.

You may need to try this More than Once... Be sure to Follow ALL the Steps...
Take your time... Pay particular attention to Steps 3 and 4.
Some users have reported as many as 8 or 9 attempts were necessary before success.
If the issue persists...
Then a Visit to an Apple Store or AASP (Authorized Apple Service Provider) is the Next Step...

What version of iTunes are you using? The latest is 10.6.3. In iTunes, choose Help -> About iTunes to check the version number. If it's lower than 10.6.3, download the latest version from here.

HT1386 we are using same laptop with my wife for our 2 iphones and when sincronizing, she's getting my apps and is requested for my apple id and password when getting a new app on her device. How can i fix that issue?

Each phone needs to set its own sync settings on the various tabs in iTunes. On the Apps tab, for example, uncheck the apps that you don't want on the phone being synced. This article may also be of interest: http://gigaom.com/apple/itunes-101-multiple-devices-one-itunes-account/.
You can change the Apple ID used for purchasing on her phone by going to Settings>Store>Apple ID, tap the ID shown, sign out, sign back in using her Apple ID. However, be aware that if she has any apps on her phone purchased with your Apple ID she will still be prompted to enter the password associated with this ID for all future updates of these apps. This is because apps are permanently tied to the Apple ID used to purchase them, regardless of the ID in Settings>Store.

If possible, connect to your router with Ethernet and turn off Wi-Fi. Any difference?
