Has my cable router been hacked?

Episode 1661

Charles from Virginia Beach, VA

Charles bought the CM1000 cable modem and an Netgear ORBI Router. But he's heard of a hack in cable modems. True? Leo says that there is a vulnerability called "cable haunt" that will allow someone to take over your cable modem. And there's no fix because your cable internet company doesn't want to do it since it'll take your internet down while they fix it. Additionally, the cable company wants him to pay for customer support every month to fix it. Leo says you have to keep putting pressure on the cable company to fix it. There is a workaround though.

Can I put a lot of hubs on my router?

Episode 1661

Tom from Atlanta, GA

Tom's router has four ethernet ports. Should he use them to install multiple hubs with switches or multiple switches? Leo says that switches aren't very smart on the whole, and switches are really just another name for hubs. What you need is a smart switch to really isolate the traffic and maximize your speed. Leo has a 24 port switch connected to his Orbi router and he uses that to connect all his devices that need a wired connection. That includes his streaming box and TV. 

Can my NAS be hacked?

Unraid

Episode 1651

Brett from Tacoma, WA

Brett is worried he's been hacked. He used UNRAID to create his own Network Attached Storage. But he recently got a message that he had 114 login attempts on his network. Leo says that it is very common. Any server that is online and attached to the internet will be attacked. Mostly by a bot that is programmed to look for servers online. Make sure you have security features that only allow logins from approved regions, IP addresses, or from your work. There should also be a feature that will lock out an IP address that keeps trying to log in.

Can I use my own router for FIOS?

Verizon

Episode 1651

Andrew from Brewster, New York

Andrew has Verizon FIOS and wants to know if he can use his own router. Leo says that Verizon bundles the router/modem together. Leo says you won't save any money since you have to use Verizon's modem/router anyway. But if you want to do your own router, you can turn off HDCP in the Verizon router and then use your own router for a better experience.  Here's a YouTube video on how - https://www.youtube.com/watch?v=w2Jr_0P0zwY

Can I Recover My Data From a Bad RAID Recovery?

Recuva

Episode 1648

Alan from Adelaide, AUS

Adam wants to create a new RAID 5 array, but his current RAID 1 system went belly up as he was converting to RAID 5. Can he get his data back? Leo says probably not through the RAID itself. He could take one drive out and try to recover, but Adam may have been too deep in the conversion process to restore the data. But the good news is, that he can take the drive out and plug it into the existing PC and see the data. If the data is mirrored, it should be easy to recover with a utility like Recuva. EaseUS also has a free drive recovery tool. He can probably use those to see the files.

Netgear AC1200

Episode 1647

Jack from Stone Mountain, Georgia

Jack's mom is moving into an assisted living facility, and he wants her to have her own WiFi. What router should he get her? Leo says it's a good idea to give her own WiFi access point. It'll protect her. NetGear makes great WiFi Routers. How about a basic wireless access point? Leo says that the router will be better for security, but a WAC is fine. 

Should he get a Samsung Galaxy Note 10? Leo says that since Jack has a note 8, he can trade it in and get a great deal on a Note 10. Go for it.
