Troubleshoot iPhone 5 Wi-Fi Internet Connectivity Problems on Virgin Media

I generally can't fault Virgin Media's high-speed broadband service -- I'm on the 100 Mbps service and it's fast and reliable. However, my Apple iPhone 5 has experienced significant connectivity issues when hooked up to Virgin Media broadband via the Virgin Superhub router. Even though the Virgin Media Wi-Fi signal was strong, the connection on the iPhone 5 could be painfully slow and often hung for long periods of time.

Fortunately, a small tweak to the Superhub router network security settings has massively improved the iPhone 5 Wi-Fi connection, so I thought I'd share this tip in case it helps other people.

Improve iPhone 5 Internet Connectivity With Virgin Media Superhub

The basic problem seems to be that the iPhone 5 just doesn't get on with the Virgin Media Superhub's default WPA protocol setting of "WPA Auto." You can get around this problem without compromising your home or office Wi-Fi network's security by changing this setting to "WPA2-PSK[AES]." Since making this change, my iPhone 5 has delivered an Internet connection as fast and as reliable as all the other devices I connect via the Virgin Media Superhub router. Here's how to do it in simple steps:

  1. Sign in to your Virgin Media Superhub's settings screen by going to "192.168.0.1" in the Web browser on any PC or laptop connected to the router (wirelessly or with an Ethernet LAN cable). If the page refuses to display first time, power the router off and on and then try again.
  2. Click the red "Advanced Settings" button at the bottom of the main Superhub welcome splash screen after you have signed in.
  3. Choose "Primary Wireless Network (SSD1)" in the Wireless section at the top of the page.
  4. Select the "WPA2-PSK[AES]" radio button to enable this function and, at the same time, deselect the "WPA Auto" default setting.
  5. Click "Apply" at the bottom of the page to store your preferences.

That's it your done! Give your iPhone 5 a try again and see if your Internet connection is any faster and more reliable. If you still encounter issues, you could also try slowing the router down from a max setting of "300 Mbps" to "140 Mbps."

Protect Yourself Against GameOverZeus and CryptoLocker

GameOverZeus/CryptoLocker protection. 
Hundreds of thousands of people across the globe are about to have their bank accounts emptied of cash. It's all thanks to the GameOverZeus and CryptoLocker malware/viruses. Here's how to find out if your computer has been infected by GameOverZeus or CryptoLocker and, if so, what you can do to prevent them.

A concerted action between law enforcement agencies around the world has, so far, managed to slow down and contain the threat of GameOverZeus and CryptoLocker but this "period of grace" won't last forever and, sometime soon, the hackers will get their act together and overcome the temporary halt.

The problem with GameOverZeus and CryptoLocker is that many target machines have already been infected. Fortunately, law enforcement have been monitoring which machines are already infected and have notified the relevant Internet service providers.
