Gigabit speed expectations over WiFi

At this time, Business Internet 1 Gig delivers speeds that are faster than some of today's most advanced smartphones, laptops and tablets are capable of providing via WiFi. To help potential Gigabit Internet service customers better understand what download speeds can be expected over WiFi, we tested the WiFi throughput of some of today's leading devices under a variety of conditions.

Although download speeds up to 940 Mbps are possible with a hardwired connection, maximum WiFi speeds could be limited by your device's age and model. Other factors could include how many WiFi-connected devices are in use, website traffic and content provider server capacity.

Speed tips

If you have hardware, software and related equipment configurations that can connect to the Internet but that are different from the above recommendations, they will still work with your Comcast Business Internet service; however, our testing has shown that these recommendations will work best to achieve your provisioned broadband speed.

If you are not experiencing the speeds you expect, remember to test using a hardwired connection to the Internet. Also, make sure you are not in the process of downloading or uploading anything, close all programs using the Internet and power off any other devices that are sharing your network.

Remember, there are a number of external factors that may limit your speed; as a result, actual speeds may vary. For the best performance, contact your device manufacturer or software provider to learn about required upgrades, configuration updates or to find troubleshooting guides.
