Ellie is cruising the Hawaiian Islands. What should she do for internet access? Should she buy the cruise ship internet? Leo says don't ever do that! It's satellite internet and it's only a few MB up and down, and everyone on the ship has to share it. She'd have to get up in the middle of the night to get decent speed. It's also obscenely overpriced. Since Ellie is cruising around the Islands, she may be able to rely on local cellular service if she's near shore. She'll have data, but won't be charged a roaming fee. AT&T says that she will, though. Leo says that's nonsense.
Ricky has Sonos, and after a recent update, he can't get his Sonos speakers to play in party mode. Leo says that may be due to it choosing a speaker to act as the main portal. Leo has had similar issues, and he solved it with a boosted Wi-Fi device. A recent update was supposed to fix all that. The more likely issue, though, could be plain old congestion. Everything has Wi-Fi now, and as a result, it causes rush hour. Leo recommends un-pairing everything.
Mike wants to know what he needs to use his iPad on Wi-Fi. Leo says that any iPad will work on Wi-Fi. If he has LTE, however, he could use it anywhere. But for Wi-Fi, a regular iPad will work just fine. Since Mike is traveling internationally, Leo recommends also getting a MiFi card, which he can put a local SIM in for Wi-Fi. But since Mike is in the US Virgin Islands, international data roaming won't be an issue. Leo recommends getting an AT&T carrier version of the iPad. Leo likes the iPad Mini for traveling.
Kevin needs to have more than two ethernet ports on his router and his mesh router only has two. Leo says he can get an ethernet switch or hub that can expand the amount of ports. Leo has one with 24 ports! They're all easy to use, and the best part is they're all the same. NetGear makes a good one. But any one will do.
Jane had DSL Extreme, but she says that AT&T won't allow it over the phone lines anymore. Leo says there's something going on with her particular neighborhood. She's still getting phone service, though. Jane says that AT&T isn't offering DSL either, but they're trying to push UVerse. Leo says that AT&T has decided to eliminate copper in her neighborhood and start using fiber. Fiber is glass and works better than copper.
Leo says there's a new feature in Android Oreo 8.1 — it will let you know how fast a Wi-Fi access point is before joining it. Leo says any password vault should enter his password into the web portal when he signs in. Leo prefers using password vaults to any mechanism offered by the browser or phone itself. Password vaults will remember all of his passwords, and on Android, it will actually fill in the password automatically.
Jerry says that the old "can-tenna" hack, where you focus the Wi-Fi signal through a pringles can could help getting better Wi-Fi coverage. Leo says that's not going to punch a digital hole through a concrete and rebar wall. It also would only work one way. It's a fun project, but not really ideal for practical use. Is there a radio app that gets the tech guy show?
John is a landscape contractor and he's making the transition to Wi-Fi controlled sprinkler systems for his clients, but there are some locations where the Wi-Fi is just too weak to connect. Is there a booster device he can use? Leo says that he can do that, but he'd need boosters for both directions.
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.
You may have heard about the latest Wi-Fi vulnerability in the news called “KRACK” or “Key Reinstallation Attack.” This is a security flaw in the WPA2 protocol that could allow a third party to intercept network activity between a router and a device. It does this by taking advantage of a problem with the way the client (your mobile device or computer) authenticates with the access point (the router).
