Key Things To Look For When Buying Spectrum Modem

Compatibility

Before you research the specifications of the modem you want, you should check if the modem is compatible with Spectrum. It will be a problem if the modem you get is not compatible since it will be impossible to make it work. Routers are more versatile than modems in terms of compatibility. Therefore, it is best to choose a cable modem for Spectrum. 

Ideally, you get a modem that states that it works with Spectrum. In case you got a modem that should be compatible with Spectrum but not working, you can call Spectrum to check what the problem is.

Upload and Download

The speeds indicated can be enticing. However, you have to keep in mind that this can be a combined speed than the speed you need to know. When you play games or stream videos, what you need to check is the download speed and not the combined speed. 

Normally, if the download speeds are good, the upload speeds will be satisfactory as well. In checking the speed of a modem, it is recommended to look if the speed is a combined one or download speed only.

Security

When looking at Spectrum compatible cable modems, security is one of the important considerations. A virus, an attack, or anything malicious can easily get into your network because of the various types of malware that exist all over the world. Your modem can be the first line of defense. 

One factor you can look at is the chipset you are using. You may want to veer away from Puma chipsets since it has been reported that these chipsets have serious security problems. You can also check the kind of firewall the modem has to ensure that your network is protected. 

Ethernet Ports

When it comes to picking the ideal Spectrum modem, the number of Ethernet ports is also important. Many modems only have a single Ethernet port. This is enough if you only want to connect your modem to your router or computer. If you have 2 Ethernet ports, you can connect your router and connect your gaming console, computer, or television all at once. The number of ports might not be that important if you do not plan to stream many videos in your network.

The Difference between DOCSIS 3.0 vs. DOCSIS 3.1 Modems

When you read about cable modems, you will normally see them labeled either as DOCSIS 3.0 or DOCSIS 3.1. However, if you see a modem lower than this, you better not consider it. The DOCSIS 3.0 mode has a minimum of 4 channels so that there will be better traffic flow in your network. 

DOCSIS 3.1 modems have their channel size increased. Therefore, you can easily have a large data amount at once. Moreover, DOCSIS 3.1 modems are made for the future. You can expect it to handle better internet speed development in the future. 

The problem with DOCSIS 3.0 is that they are limited to the available speed now. If speeds become more developed in the future, they can become obsolete. DOCSIS 3.1 modems will now have this problem. However, DOCSIS 3.0 modems are still ideal for the internet speed needs today. 

DOCSIS 3.1 modems also have better security, better utilization of power, and lesser packet latency compared to DOCSIS 3.0 modems. Packet latency is an important consideration if you need good voice quality during VoIP calls and play games.
