Once you have WiFi in your home, you’ll want to make sure you’re getting the most out of your connection. Older equipment and poor network configuration can slow down the speed of your WiFi connection in your home, which could lead to slower downloads, lagging online games and streaming video, and overall slower Internet performance. What else can impact the speed or performance of your network?
Number of WiFi devices on your home network
Interference from neighboring WiFi networks
Limitations of individual WiFi devices
Distance between the wireless gateway and your WiFi-enabled device (i.e. mobile phone, tablets, laptop, etc.)
Physical factors (i.e. home construction, apartment vs. single home)
Here are a few ways to improve your WiFi network.
Wireless Gateway Placement
Place your Gateway, modem or router in the most central location of your home, preferably on the main floor instead of the attic or basement. Make sure it is at least a couple of feet off of the floor and confirm that the coax cable connection is finger tight. Avoid putting your Gateway or router in cramped spaces or next to anything that can block the WiFi signal. The best position is in an open space away from thick surfaces (e.g., concrete walls) and other household electronics that may cause interference with the WiFi signal, such as baby monitors, cordless phones, microwave ovens, refrigerators and Bluetooth-connected devices. **Note**: Consider adding Xfinity xFi Pods to help extend your home WiFi coverage throughout your home. To learn more and purchase, go to xfinity.com/xfipods .
For the best WiFi reception and the least interference from nearby wireless networks, place your wireless gateway in an open area, away from:
Metal surfaces (including computer cases)
Microwaves and refrigerators
TVs and computer monitors
Cordless phones (excluding DECT or 900MHz models)
Large amounts of water (like aquariums and water heaters)
Keep in mind that the WiFi-capable devices you connect to your in-home network play as important a role as the wireless gateway when it comes to range and speed issues. Additionally, locations that tend to have high WiFi usage, such as crowded neighborhoods and apartments, may affect your speeds, especially during peak hours.
Regularly Reboot Your Equipment
Rebooting (or restarting) your Gateway, modem or router is good for the device's health and for your home WiFi performance. Doing this allows the device to update its software, if necessary, which can help optimize your connection and speed. Learn how to restart your WiFi equipment.
Confirm Your WiFi Network
Sometimes you may be connected to your Gateway's public WiFi hotspot network ( xfinitywifi ) or secure hotspot network ( XFINITY ), which can limit your WiFi speed. Go to the WiFi settings of your device to make sure you're connected to your personal in-home WiFi network.
Connect High-Bandwidth Devices via Ethernet
Whenever possible, plugging stationary devices directly into your Gateway or router using an Ethernet cable may provide optimal connectivity. For example, it's ideal for desktop computers, gaming consoles and video streaming devices to be connected with an Ethernet cable instead of connecting wirelessly, since activities on those devices use a lot of bandwidth (e.g., graphic-rich online gaming, movies or TV shows).
Check Bridge Mode and Antennae for Third-Party Routers
If you use your own router along with your Gateway, make sure the Gateway is in bridge mode. Learn more about bridge mode . You'll also want to position the antennae of your router so that one is pointing vertically (12 o'clock), and the other one is pointing horizontally (either 3 or 9 o'clock) to broadcast the strongest signal.
Consider a Different Speed Option
If many devices access your home WiFi network at the same time, you may want to consider a higher speed tier to improve your network's performance. We offer several speed options to serve your needs. Visit My Account to see which level of Internet service you have and the upgrade options that are available.
If you use a separate router along with the wireless gateway, make sure the wireless gateway is in bridge mode. (See Enable or Disable Bridge Mode on a Wireless Gateway.) To find out more about wireless networking, please see What is WiFi? to find out what WiFi is and how it works. For information on home networking and how to set up a home network, see What is Home Networking?
Upgrading Your Modem
Comcast provides several levels of Internet service offering different speeds, such as Performance, Blast! and Extreme 105 or Extreme 150. Your level of service is listed on your billing statement. Because some older modems and gateways can’t adequately support higher levels of Internet service, you may still be accessing the Internet at slower speeds, even if you’ve upgraded your plan. If you lease a modem/gateway from Comcast, you’ll want to upgrade your modem/gateway to make sure you’re getting the fastest network speeds possible. You can find a list of Comcast-approved modems and their specifications at the DOCSIS Device Information Center. To find out more about upgrading your equipment, see Upgrade Your Wireless Network Equipment.

Other Factors That May Impact WiFi Connectivity:
Technical limitations of personal devices (e.g., an older phone that can't handle faster speeds, out of date operating systems, etc.)
The distance between personal devices and your Gateway/modem/router
Older devices which could be consuming bandwidth and slowing down your network
My Comcast Internet services were just installed, how do I find my WiFi network?
The following instructions are for Xfinity Wireless Gateways only. If you use an approved third-party modem or router for your Internet services, please refer to its user manual.
Your Xfinity Gateway comes with a default WiFi network name and password. If you have never personalized your WiFi network name and password, you can retrieve your default WiFi information on the side or bottom panel of your Gateway:
If you change your password from default settings (strongly recommended), you can access the information several ways:
Xfinity My Account Online
Xfinity My Account App for Mobile Devices
X1 TV Box (View Only)
Xfinity Wireless Gateway Admin Tool
Any time you change a WiFi name or password, you must reconnect all your WiFi-enabled devices by entering the updated network name and password under the device's WiFi settings. **Note**: Xfinity Gateways provide dual-band (2.4 GHz and 5 GHz) functionality and the ability to broadcast two networks. If you have an xFi Gateway (Arris 1682G, Cisco 3941T, Arris 3482G, Technicolor CGM4140COM, Cisco DPC3939 or Arris X5001), we strongly recommend using the same network name and password for both bands. Doing so allows the device to optimize network traffic and improve connectivity.
