 In a separate article (How to stop your Mac from joining the wrong Wi-Fi network), we looked at how to control which Wi-Fi networks your Mac can automatically join, and which takes priority.
So, how can you do the same on your iPhone & iPad - especially if it keeps joining the wrong network. On our iOS devices, we do not have an option to see a list of ALL the Wi-Fi networks you have joined. However, when you are in the vicinity of Wi-Fi devices that you have previously used, you do get the option to tell your iOS device to 'forget' that network or to tell your device that you do or don't want to 'auto-join' that network.

In last week's newsletter, we included an article that described a quick solution to a poor Wi-Fi signal.
But does your Mac's Wi-Fi keep joining the wrong Wi-Fi network? If you live in an area that has Telstra Air - or have multiple Wi-Fi Access points or networks that you choose between - then you can find that your Mac seems to 'prefer' the wrong Wi-Fi connection and automatically joins that one. If this happens, your Mac looks like it is connected to Wi-Fi (and you therefore assume you should have internet), but you may find your internet slow or non-existent. This issue came up again last week, from a client who lives in Southbank (Melbourne) and finds that her Mac keeps joining Telstra Air ahead of her own Wi-Fi. In fixing the problem for this client, I noticed that Apple has provided a new setting in relation to 'remembered' Wi-Fi networks and whether these networks are 'auto-joined'. So I have updated this tip to reflect this new feature. Read on below.
 A new flaw in Wi-Fi security could leave all our devices vulnerable to hackers, according to reports in the press this last week. Here is an article from Fairfax media this week about the flaw, which relates to the WPA2 security protocol that our routers use. Apparently, iOS devices (iPhone, iPad, iPod touch), Windows computers and Android devices are at risk, with Android devices being at higher risk than the others. (The articles I saw did not mention Mac computers.) Microsoft, Apple, Google and router providers are all working on patching this security hole, and will release updates to their operating systems and router 'firmware' in the near future. To ensure that your own devices and computers and computers are not left vulnerable, it will be essential to apply any updates that are released for your devices. I will advise in the iTandCoffee fortnightly newsletter when such updates are available.  One thing that may trip a lot of people up is how to update the 'firmware' of their router - since the router is the device that is the centre of this vulnerability, and the imminent firmware update will be essential to ensuring your ongoing security. If anyone needs assistance with this, iTandCoffee will be able to help - in your own home if necessary (depending on your location).

 For anyone that makes use of public WiFi networks at cafes and restaurants, shopping centres, airports, hotels or elsewhere, you really do need to be sure that you are not exposing your passwords and private details to others that may be on that network - people who 'camp out' on the network looking for unsecured communications over the internet. The Age published a good article on this topic this week. Here it is: Related Handy Hints and Articles |
