How effective is powerline networking?

TP-Link AV2000 Powerline Adapter Kit

Episode 1382

Patrick (MacMan) from Indianapolis, IN

Is powerline networking a decent option these days? Leo says that it's improved a lot since it was introduced 20 years ago. It was horrible back then. Now it's much better. He won't get the full throughput, though – Only about 60%. And he'll have to be on the same fuse box. Leo also recommends the Plume routers because they have ethernet connections as well, so he could plug in there.

What's the difference between a router and a modem?

Modem vs router

Episode 1381

Christian from Nashville, TN

Christian wants to know the difference between a router and a modem. Leo says that they handle two different jobs but some people get a modem that also works as a router from their ISP. Modem means "modulate-demodulate," and in the early days, it would take the bits and turns them into sound and then back again over a telephone line. Now they send the data digitally. Then it converts it into RF signals and back to bits.

Do I need a managed switch for my network?

David from Palm Beach, FL

David has multiple TVs and computers and would like to link them all together with a switch. Should it be managed or unmanaged? Leo says that networking is a high end technical topic. A router manages the traffic and routes it through to the proper device. Routers use QOS or "quality of service" to do it. A switch is still needed, though, and it reduces traffic. A managed switch would allow him to run protocols and control the network properly. Most people don't need a managed switch.

What router should I buy?

Paul from Columbus, OH

Paul's daughter has a really old router and it's starting to flake out, so it's time to get a new one. Leo says she should get a dual band router that supports not only 2.4 Ghz, but also 5Ghz. She'll want one that supports 802.11ac. The reason to get a dual band router is that everyone is on 2.4 these days, and while 5 GHz is limited and won't go through walls, it is barely used.

How can I find out what devices connect to a router?

WiFi Pineapple

Episode 1374

Isaac from Los Angeles, CA

Isaac is a cop and wants to know if routers collect data of what connects to it or sees it. Leo says only if the device was connected to that router. Just seeing it is another matter, and that's unlikely. Android has an app called WiFi Collector from NirSoft, but that's the opposite direction from what Isaak wants. Leo says that the WiFi Pineapple from HakShop could work for this.

Why does my network drop when uploading?

Google Photos uploader

Episode 1367

Brad from Bethlehem, PA

Brad says every time he tries to upload his photos to Google Photos, his Wi-Fi fails. Leo says that turning his Wi-Fi off and on could help as it renews the "lease" on the router with a new IP address. Something inside the Mac's network settings could be messed up, and renewing the lease can fix it.

It could also mean that the computer has lost contact with the router. He should reset his AirPort and update the firmware. That chatroom says it may be Google Photos that's causing the issue as well.

Improve Your In-Home Wi-Fi

Wi-Fi is great when it works, but all too often there are problems that cause disconnects or slowdowns. If you have a large house, or there are too many walls that make it hard for signal to travel through, you may need more than just one wireless router.

One option for improving your reception is to set up a secondary Wi-Fi access point to extend your current Wi-Fi router. You'll want to buy an extender from the same company that made the router you already own. Set up the extender in "bridge mode" and it will rebroadcast the signal and extend its range.
