Yesterday, all the extensions for Firefox suddenly stopped working. Leo says it turned out to be that Firefox forgot to renew their certificate for security, causing them all to stop working. Now they're pushing out a fix to get things back up and running.
Jason called last week about his phone's screen freaking out. Leo thought it was the proximity sensor causing the problem. Jason did a factory reset and that solved the problem. Leo says that may have indicated a failed update. The first thing he should do when something weird happens out of nowhere is to do a factory reset.
Darren is looking to upgrade his network to a Mesh router and is having issues connecting his WyzeCams. Rich says that a lot of people are having issues with this because the WyzeCams are 2.4ghz and the mesh routers will switch between 2.4 and 5 GHz. That can cause camera connection issues. Google's mesh router will automatically connect to the band that the camera supports. So he may want to check out the Google WiFi mesh router.
Rich has Eero and he was able to hook up his WyzeCams without any issue.
Larry is a gamer and got a new video card that supports RayTracing. He put it in his computer but it's lagging terribly. On top of that, he's now getting "green sparkles" everywhere. Is his machine too old? Leo says it shouldn't be too old at all, it's likely just a bad card. Green artifacts are usually an indication of a bad video card, so Larry should send it back for a refund or replacement. The GTX 1070 is better matched to his computer anyway.
Greg can't mirror his phone with his Samsung smarTV, but he can use his hub to search the internet. Leo says the TV has to be cast-enabled to do it, and the feature may not be turned on in the settings. It could be DNLA or AirPlay. But it also says "smart hub is trying to update." Leo says that Samsung is notorious for not updating their TVs, and it will eventually get to the point where it can't be updated online. It's clearly looking for the update though. Samsung does suggest you can reset the country and that will fix it. The wrong country code could very well cause this issue.
Fred has a 2008 MacPro Cheesegrater, and he doesn't want to replace it. But it's having kernel panics. What can he do? Leo says a kernel panic is Apple's version of the blue screen of death. And it usually means it has a driver issue or a hardware issue. And sometimes, the first line of the panic will tell you something useful. Bad memory is a common cause of them. Power supply failing is an indicator. Try swapping out single RAM cards. That can tell Fred which RAM is acting up. He could just get one of the latest MacMini's and get a Thunderbolt 3 connection.
Max is having issues with his TV speakers on his Vizio D series TV. He keeps hearing audio coming out, even when it's off. Leo says that today's modern TVs don't really turn off anymore. They just go into a very low power mode. Leo suspects that Max's Xfinity cable box woke his TV up through HDMI. Leo recommends putting the Vizio into Eco mode and it will turn off. Then, he should turn off CEC in his TV settings.
Patrick has a Dell Inspiron Desktop and wants to know why his computer doesn't know what time or date it is. Leo says that means the CMOS battery on the motherboard is dead. Just replace it. It's about the size of a quarter.
Tom has a NUC computer and after updating to Windows 10, it takes several hours for Windows to come alive on the screen. Leo says that wiping the drive and reinstalling could fix it. It's probably a bad hard drive sector that the computer is trying to read. Do a full reset and wipe the entire thing. But make sure to back up data first. Another option would be to have a USB key with Linux on it and boot to it (F10). If it comes up right away, then you know there's something wrong with the software. If it's the same problem, it is a hardware issue.
Carlo has a small laptop with a USB 3.0 port. But suddenly, it won't read USB 2. What gives? Leo says that USB 3.0 is supposed to be backwards compatible as long as the plug is Type A. It could be a faulty connector, or the connector pins are dirty. The connector could have also shorted out. Shine a light in and look for some cruft, or even damage on the surface of the contacts. ScooterX in the chatroom suggests that it may be a driver issue. Go into the device manager (windows key + X) and look to see if there's a red X. Or delete the drivers and then restart to reinstall.
