802.11n

Why can't I connect to 5GHz on Wi-Fi?

Wi-Fi

Episode 1503

John from Oxnard, CA

John upgraded his internet but his laptop says it only has 2.4 GHz available. Leo says that means his router is only 2.4 GHz. 802.11N routers are dual band with 2.4 and 5 Ghz bands. And there's even tri-band routers that offer two 5 GHz channels along with a 2.4 GHz channel. His laptop may also just be able to connect to 2.4 Ghz. John should look in his BIOS and software to see if the 5.0 GHz band is turned off.

How can I improve my Wi-Fi Signal at home?

John from San Diego, CA

John is frustrated with the slow speed of his wireless connection. Leo says it largely depends on the speed. 802.11n is the fastest, but it's being supplanted by 80211.ac. John has an 802.11g router and that's not as fast as n. The farther away a router is, the slower the Wi-Fi signal gets. Congestion by competing Wi-Fi access points can be an issue as well, since everyone is on the same spectrum - 2.4Ghz. That's why Leo recommends using dual band routers which also run on the 5Ghz band spectrum.

How many wireless devices can a router handle?

Mike from Norco, CA

Mike is having connectivity issues with his home network and is wondering if he needs a new router. He has a desktop, three laptops, and a smart TV. Is that too many? Leo says yes and no. It depends on what he's doing. If everyone is streaming Netflix at the same time, the bandwidth won't really handle all that activity. On the other hand, if everyone is just emailing, then it should be fine. Four or five devices shouldn't be a problem. If his router is 4 or 5 years old, then it may be showing its age.
