Question   Need to turn off the 5gz Wifi network and only run the 2.4gz so I can install my security cameras (Zmodo), how do I do this?   Answer   You can restore the separation of your 2.4 Ghz and 5 Ghz bands. To do so, you will need to give the two bands separate names, and even separate passwords if you want. Once you have completed that in the xFi portal, you can then connect your computer to this 2.4 Ghz band to install your cameras.    Changing xFi Network Settings:   To access network settings from the xFi web portal, select Network from the top navigation. From the Xfinity xFi app, select Network. Select Edit next to your WiFi network to update your WiFi name and password or set a WiFi name and password for each radio band (i.e., 2.4 GHz and 5 GHz). You can give each radio band the same name and password to make it easier to remember. Selecting Edit also allows you to change your security settings and choose whether you hide or broadcast your WiFi name.

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 .   Minimize Interference For the best WiFi reception and the least interference from nearby wireless networks, place your wireless gateway in an open area, away from: Walls Furniture Metal surfaces (including computer cases) Halogen/fluorescent lighting Microwaves and refrigerators TVs and computer monitors Cordless phones (excluding DECT or 900MHz models) Baby monitors 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.   Other Considerations 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.   For more information, see https://customer.xfinity.com/help-and-support/internet/improve-your-wireless-home-network/   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
