Wi-Fi routers, home servers, virtual private networks, and more.
Bob is looking for software that can test all his network switches to see which is going bad. Leo says that there is an article on Tom's Hardware on how to test network switches. That includes some software to test it. GL Communications makes software ethernet and packet checker called Packet Check.
Matt is building a new house and has run cat 5 ethernet around the house. But should he also use a mesh router? Leo says he uses Eero at home, but here is one mesh system that's great specifically for Matt's situation: Plume. Plume sells tiny little access points that plug into the wall with an ethernet port. It's still part of a larger mesh network, but it creates very localized access from the ethernet.
Heidi is worried about the Russian VPN Filter hack. She bought a Netgear router to replace it. Is she safe? Leo says that some Netgear models aren't protected, but if she installs the latest firmware, she should be OK, and NetGear does update routers automatically.
Neil is worried that the VPN Filter hack will affect his Asus router because his model isn't protected. Should he be worried? Leo says first thing he can do is update his firmware. Asus keeps their firmware up to date regularly and uses open source DD-WRT firmware. So if there isn't one, he can patch it himself. But Asus routers are great because they update them constantly. Neil should reload the most current firmware, even if he has already updated it. That will wipe out any additional problems.
Ron has UVerse and an extender and it slows to a crawl when he streams. Leo suspects that it's his modem that's causing the problem. It's likely an out of date modem that's slowing the network traffic down. Rebooting could help. A better Wi-Fi router could help too. Routers do wear out over time. Leo recommends the NetGear Orbi. He can set up the AT&T router to work in bridge mode and then use the new router to route the traffic. It'll be a lot better.
Jeff wants to extend the range of HDMI to other parts of his house. But when he does, he starts to lose signal. What can he do? Leo says that Baluns are good for that. It stands for "Balanced/Unbalanced" and it will convert HDMI to ethernet and back to HDMI so that he can stretch it hundreds of feet with no signal loss at all. Jeff should check out Monoprice.
Lori can't get access to her Exchange server. Her password doesn't work ever since an employee who was running it left the job. Leo suspects he changed the passwords before he left. But if she has physical possession of the server, she should be able to change the passwords. If the employee has access to her server, then he has control, even outside of the company. So Lori will have to go to him or the company he represents and get the passwords. If he's proven to be untrustworthy, then they'll probably have a hard time getting that information.
Kevin needs to have more than two ethernet ports on his router and his mesh router only has two. Leo says he can get an ethernet switch or hub that can expand the amount of ports. Leo has one with 24 ports! They're all easy to use, and the best part is they're all the same. NetGear makes a good one. But any one will do.
Tim bought a new NetGear 7900 router, but he had to reboot it every few days. So he returned it and doesn't know what to buy now. Asus is a company that offers a similar router design. It's an open source based router that uses DD-WRT and Tomato. That's what Leo would buy. NetGear also has the problem of being susceptible to the Russian virus, along with TP-Link and several others. Leo suspects that's because they aren't updated as often.
VPNFilter has compromised over 500,000 routers in the US and can only be wiped if you reboot the router. It can also affect a vast array of routers. To find out if your router is vulnerable, check out this list at symantec.com.
While you're at it, it may be a good time to update your router firmware too.
