If you aren't checking your Internet speeds on a weekly basis, you might not know when there's a problem. You aren't likely to notice a difference between 150 Mbps and 80 Mbps download speeds when you're browsing websites, watching (1080p) YouTube, or chatting with friends, but if you're downloading a huge Fortnite update, why drive in the slow lane?

Android/iOS: What's on your network? You can always pull up your router's web interface to get a sense of which devices are connected, but you're probably just going to get a list of MAC addresses and assigned IPs - not very helpful.

New levy will help fund the rollout of the National Broadband Network (NBN) in regional areas but additional charges may be passed on to consumers.

Windows only: If you're running a home network with more than one or two machines, free network tool Advanced IP Scanner might save you a good chunk of time hunting down IP addresses and remotely connecting. The small utility scans a range of internal IP addresses and reports the status, name, NetBIOS/workgroup name, and MAC address on what it finds. You can then remotely shutdown, wake up LAN-listening machines, telnet or FTP into a machine—anything you'd normally be able to do, just in shorter order. It's probably overkill for those with one or two machines with static IP addresses, but Advanced IP Scanner is a pretty sweet tool for networking geeks. Advanced IP Scanner is a free download for Windows systems only. Thanks, brodiemac!

If you're running a Windows system, the Online Tech Tips blog has a step-by-step tutorial on "spoofing" your address to something you can remember, or for hooking into a wireless network that's locked down. The guide is written for Windows XP, but the steps look much the same as they would in Vista. Change or spoof a MAC address in Windows

Backing up your data on a regular basis is important, and turning a spare computer into a backup server is often the best way to make sure it gets done. But most methods require either a good deal of command-line learning or serve only one operating system. Not with Restore, a free, open-source backup system that can install or run from a live CD, work with any OS, and operate through a simple browser-based interface. Today I'll demonstrate backing up a Windows laptop to an older desktop, but you'll see how Restore can be easily molded to fit just about any home backup needs.

US-centric: If you want to block your cell phone number from showing up on other phones (for whatever reason), you can do it temporarily simply by dialing *67 before the number you're calling. According to tech how-to site How To Do Things, you won't have any way to tell this is working (it does), but if you want to reassure yourself just call another phone number that has caller ID to double-check that your number, indeed, is blocked.
