Jeff is having issues with his WiFi coverage at his studio. Leo says that congestion is a major problem with WiFi because of the Internet of Things, phones, tablets, the works. What Leo recommends is Powerline Networking. It's gotten a lot better the last few years and being wired will always be better than WiFi. So check it out. TPLink makes some great PLN devices.
Lynn's wifi drops out from time to time. Leo says that's usually an indication that your router is worn out, but if it's new, then it could be congestion from other WiFi signals in your neighborhood. Using a dual band router with a 5Ghz frequency, that can help, because not only are other routers using 2.4Ghz, but there's also all the smart devices that use them as well. So it's really congested out there.
Corey bought an ORBI MESH router and enjoyed 350MBps downloads, until recently. It's now down to about 10MBps. He tried another Linksys mesh router and the same issue happened. Leo says that it sounds like the problem isn't at the router level. Leo suspects that Corey may get full speed from a wired router. If so, then there's a congestion or interference issue. It could be a "WiFi hostile" environment that is causing interference. Maybe a lot of devices are clogging up the wireless spectrum where he is.
Clarence has issues with his laptop's Wi-Fi intermittently dropping after adding a new modem and Netgear router. Leo says to connect the laptop directly to the router and see if it drops out. If it doesn't, then he'll know the internet connection is fine, and the Wi-Fi radio in the laptop is flakey. If it keeps happening, then that would lead to his router, or even modem. Another possibility is the power-saving may be turned on in the Wi-Fi settings of his laptop. Just disable power-saving and it should be OK from there. It could even be congestion from other internet devices.
Jeff wants to know why his internet slows down at night. Leo says that he ends up sharing bandwidth with his neighborhood and if it's slowing down in the evening, it's because everyone is on Netflix. He also has to factor in Wi-Fi congestion. Jeff could bypass the Wi-Fi router and plug directly into the modem and see if it speeds up. If it does, then he'll know it's Wi-Fi congestion. If not, then he'll know it's his because of heavy use in the neighborhood.
Arthur uses YouTube and he says that it's so compressed, it's absolutely unwatchable. Leo says that when he's streaming video, it's largely dependent on his bandwidth. The less bandwidth he has, the lower his resolution is going to be. He can adjust the quality he's getting in the settings, however, but at the end of the day, he may need to just get more bandwidth.
Peter has a Sonos wireless home theater and he's having some interference issues. Leo says that Sonos uses its own spectrum, and he can select standard WiFi instead. But chances are, he's running into plain old congestion as other home theater and Wi-Fi units are taking up the bandwidth. If he can, he should move it over to the 5GHz channel instead. He'll have to re-pair them, but it'll be worth it. It could also be an issue with Sonos' new 8.1 firmware update. Both Leo and Doctor Mom are experiencing the same thing, so there's something going on.
Joseph wants to know why his Wi-Fi speed is slower than it should be. Leo says it could be a variety of reasons, like distance from the access point, the amount of metal in his home, and the number of devices on the same network and bandwidth. The fastest speeds are received by being hardwired directly into the router.
Archie has a Wi-Fi router and has connected his Roku, but he's not getting good enough reception and it buffers a lot. Leo says the farther the router is from the Roku, the less connection can be made. But Leo also suspects that the router isn't giving Archie as much bandwidth as he needs. It could be due to congestion.
If his router supports the 5 GHz band, it's a much better choice for streaming. He can also take the old router and put it in bridge mode and use it as a repeater to pass along the signal.
Matthew is having Wi-Fi problems with his Asus laptop. His router isn't all that great though, and Leo has a hunch that the router is the culprit. It also may be that there's a lot of congestion by other Wi-Fi signals in the neighborhood.
