What is the best way to connect my router?

The best way to connect your router, whether using a Mac or a PC, would be through an Ethernet cable. The common ports for each device are located at the rear of your modem/router; and there are different colors for each port.

An Ethernet cable will typically have four different colored plugs: white (internet), black (power), orange (phone) and green(cable). However, sometimes this can change so you might want to check with XFinity Technical Support if you don’t know which color goes where.

Replace your Ethernet Cable

The easiest way to troubleshoot a bad Ethernet cable is to simply replace it. This is far quicker that getting a cable tester and going through the pinouts of your cable to determine if any of the wires inside the cable are at fault.

Ethernet cables are of two types namely Cat5e and Cat6. If you are looking for an Ethernet cable, it is important that you buy a Cat5e or cat6 one. These cables come in various lengths. The length of the cable will depend on how far you need to be connected from the network hub or router.

Cat5e cables are mildly durable and can last up to 10 years without any issues. They are best suitable if the device that is connected to is less than 600 ft away from the router and when there is no special requirements for internet connection such as video gaming, streaming HD videos etc.

Cat 6 cables are more durable and they have some specifications for an internet connection as mentioned above. Since the cat6 cables are more stable when compared to the cat5e, you can use them for your needs if you have a cable that is beyond 600 ft in length or needs to support better speed and quality of internet signal.

Tips for fixing Xfinity Ethernet problems

If you’re having trouble connecting to the internet with your Comcast Xfinity, the first thing you should try is plugging it into an outlet. If this doesn’t seem to be a problem then your modem might need to be restarted. To restart your modem, unplug the power cord from it and then plug it back in again after 2 minutes. Once plugged in, wait 5-10 minutes for it to fully turn on before plugging any other device into the outlet.

Pro Tip

If you still have Xfinity Ethernet problems after reading this article, then please check the status of your electrical outlet to make sure that it is functioning and properly plugged in. If that doesn’t seem to fix the problem at all, try restarting your router as well! You can contact Comcast or Xfinity Technical Support for further assistance.

Try a new Network Switch

Sometimes newer is better. If you are running an old setup in your home with a simple Ethernet hub, then an upgrade to your home infrastructure can make a massive difference. A network switch is the heart of your wired network, so it makes sense that you should go for an aftermarket solution if your network performance is not up to standard.

Advanced features such as QoS and VLANs are all available in some of the better network switches, which can give you a greater granular set of controls for you to maintain and run your home network. This means that you can prioritize applications, protocols, devices and users to get the most out of your internet by provisioning and rationing your available internet resources.

Our top picks for Ethernet Switches for Xfinity

TP-Link TL-SG108 | 8 Port Gigabit Unmanaged Ethernet Network Switch

If you only need to plug in a few extra devices, and you don’t need any management capabilities, then this is an excellent option. It’s reasonably priced with a small footprint.

NETGEAR 8-Port Gigabit Ethernet Smart Switch (GS108T) – Managed

For enhance management requirements and increased network performance this unit will fit the bill quite nicely. It runs silently and can be mounted to the wall or it can sit on your desk- your choice.

NETGEAR 24-Port Gigabit Ethernet Plus Switch (JGS524E) – Managed

If you have multiple gamers in your house that need the fastest Ethernet connections possible, then a device like this will certainly go down well. It is managed and has 24 Gigabit ports for fast network performance.

NETGEAR 18-Port PoE Gigabit Ethernet Smart Switch (GS716TP) – Managed

Not everyone needs a Power over Ethernet enabled switch, but it is still worth an honorable mention. This switch is useful for devices such as IP cameras and WiFi hotspots that can use Ethernet for both data transmission and power, so only one cable is needed when installing your hardware around the house. It is also managed, making your network highly customisable and configurable for your specific needs.

What about my wireless performance?

If you are experiencing poor wireless performance, note that your router might be being overwhelmed by the number of devices connected to it. If this is the case, then you could try switching to a wired connection temporarily and see if that helps improve performance.

This will speed things up for sure but some people prefer having stronger signals with better range over a faster connection on fewer devices. In such cases, you could upgrade or update your wireless router instead of dropping back down to using a wired connection for all of your devices.

Reduce Interference

Wireless interference can wreak havoc on an entire network so always make sure that there are no other networks nearby broadcasting in the same channels as yours. You can refer to the router’s documentation to find out what channels are best for you based on the area you live in.

Modify your Wireless Password

If you suspect that someone is snooping around your network, then it might be worthwhile to change the wireless password. Make sure that your new wireless password is complex and unique as this will help prevent others from accessing your home network. It can also be a good idea to change it periodically so that intruders cannot keep tabs on recent configurations for their own use.

Comcast Xfinity routers have been known to become vulnerable because they run an old version of OpenWrt Linux which does not support newer security protocols for encryption such as WPA2 or even WPS 2.0 . This means that if your router is using an old firmware, then it can be more vulnerable to security breaches. If you have not updated your router in a while, then you should consider upgrading to a newer version of the firmware.

For additional details about how to update your network devices and software with the latest features and fixes, please refer to Comcast’s guides on their website .

Replace Your Router or Modem

If none of these tips seem to work for you, go ahead and replace your modem or router instead. This is pretty much always faster than trying out different configurations at random since it ensures that new equipment has all the most up-to-date configuration abilities. At this point, there might be no other reason to continue using an older router or networking equipment, so it makes sense that you should upgrade in order to get the most out of your home network.

There are many newer wireless routers and modems available on the market today that not only support newer technologies such as dual band Wi-Fi, but also give you more options for configuring and upgrading your network. You might be able to find some great deals from this year’s Black Friday sales if you shop early enough!

All these are viable options for improving performance issues with Comcast Xfinity . We do stress however that getting assistance from a local professional computer repair technician is imperative before making any major changes. It can save time, money and ensure optimal results without having something go wrong along the way.

Here are some of our top picks for router/modems for your Xfinity setup:

What else can I try if I still can’t connect?

Please unplug from the electrical source and plug back in again to see if that fixes the problem.  If not, then try restarting one of these devices: modem, router or WiFi extender (if applicable). You can also use a wired LAN connection via Ethernet cable instead of using WiFi as well! This should fix any internet connectivity issues you may be experiencing while watching TV on your PlayStation 4 gaming console through Apple TV.
