Dan has AT&T and a new TP-Link router. Can he use his own with the AT&T DSL modem that has a router built-in? Leo says yes. He can turn off the AT&T's router radios and network address translation. He could try putting it into bridge mode. He'll have to open up the browser IP address and look for a place that will enable him to turn off the router altogether. He'll also have to disable DHCP. If he can't do that, then he can put the TP-Link into bridge mode and it will just pass the signal along. He should also look for a passthrough mode.
Perry has a NetGear C6900 modem/router and it just drops out for several seconds from time to time. Leo says that routers and cable modems do wear out over time, and if he gets a lot of drop outs, it could be time to replace it. But Perry's router is only six months old, so that shouldn't be happening. Leo says he could try updating the firmware. PadreSJ says that the NetGear Combo units start having memory issues that cause server busy errors. Perry should go into his settings to find the logs and see if he is getting errors like that.
Cecil has been dealing with issues with Spectrum and he's replaced the router. Can he replace the modem too? Leo says yes. He can buy his own modem and save himself a $10 a month rental charge in the process. He'll want to check with Spectrum to see what routers Spectrum supports, and based on those, he can buy his own. Most support the Surfboard DOCSIS III. There's also the NETGEAR Nighthawk.
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.
Marcello has noticed since Spectrum bought TIme Warner, he has trouble connecting to the internet. They disconnected his router and it works, though. What happened? Leo says that when Spectrum took over, they probably enabled the router side of his modem and that put it in conflict with his router.
Joe is having issues with terrible Wi-Fi downstairs. Leo says that there are two ways to improve Wi-Fi:
JC was looking for a new router to get some more advanced networking features, such as VPN and VLAN. He found the Netgear AC1750 with VPN support for $130. He found out that the VPN support also supports DDNS, which can be used for free as long as you go in every 30 days and click the link to renew it. You could also pay $50 a year for it. He was paying $45 a month for static IP addresses along with the necessary equipment and taxes to have it in his house.
George says that Comcast is pestering him to change his modem. Leo says that he'll want a faster DOCSIS 3 modem anyway, so if he's paying for a modem, he may as well get a modern one. Chances are, when he got it, it was probably already outdated. George should make sure he requests a DOCSIS 3 modem.
Robert got a new modem and now he has a random disconnect problem. He then can't get on the internet. Leo says that it could be that Robert is having issues with the router in the modem. He should go into the settings and make sure to turn off the router option. It could be running into competing routers. Leo says that the ISP could be changing the settings remotely as well. That's why Leo advises buying his own DOCSIS III modem. Another thing to do is check the network settings to see if his computer is configured to act as a router. If so, that would point to malware.
Tony's router is starting to get flakey. Leo says that we've become used to using cheap routers. However, the cheaper the router, the faster it will wear out. If Tony buys a better quality router, it'll be more consistent and last longer. Netgear makes good routers.
The problem could also be Tony's modem. He'll want a DOCSIS III modem. For that, Leo likes the Arris Surfboard SB6141 which is $70 on Amazon.
