So I got the Homerun Flex 4k up and running. It picked up several channels that although the Tablo picked up most of them too, they wouldn’t actually play on Tablo, but they do on the Homerun. So far the channels load much faster than Tablo. Unless I missed a setting in Tablo, when you open the Tablo app on Apple TV it always started at the Home Screen then you have to scroll over to live tv and select that then select the channel, again I could have missed a setting for changing that. On the Homerun you can have it set to start on what you want it to. I have it set now to start on the last live channel we watched. One downside that the Tablo does better is let you set a favorites list to weed out the channels you don’t ever watch from the guide. I can do that on my Mac, and phone with the homerun, but that selection isn’t available on the Apple TV app.
Create an account and associate it with the flex and you should get 3 forward days of free single episode recordings - no series recording or 14 day guide without the paid subscription. But mine is a kickstarter 4-tuner 4K unit and just before the flex.
Already paid for the Full Guide/DVR deal and got it set it too with a 4 terabyte drive. 
I can now say with pretty good certainty that the tuners in the Homerun are way better than the Tablo. We have one channel that is a lot lower broadcast power than all the others, and with the Tablo it would always freeze in the mornings and later in the evening and pop up a box that you had to select try again. With the Homerun there has been not one time it freezes.
I have both the Tablo and the 4k Flex and I really don’t see much difference. The big advantage for Tablo is the price, the free guide and I like the interface better for recording and viewing recordings. The flex 4k will view ATSC 3.0 stations that don’t have DRM security. I have 3 stations that don’t have DRM.
How far away are you from the broadcast towers? I am around 40 miles away and that one low power station has been a problem on Tablo since the beginning. Hasn’t missed a beat on the Homerun so far. Of course time will tell if that holds or not.
30 miles and using an indoor antenna. One VHF and the other UHF in attic.
Your homerun is connected to you network via ethernet. Did you have your Tablo connected exactly the same way?
As stated in the first post, no it was connected vis wifi, and the fact that I couldn’t get it to connect with ethernet is what prompted me to buy the Homerun.
Hey man so sorry your having some issues, I really like the Tablo but it isn’t perfect, my big issue with it is the antenna tuner is one of the weakest, even weaker than Roku tv tuners.
also they tend to over heat and they develop a lot of problems when they do. So I went on Amazon and ordered a “Quiet 80mm USB Fan, 5V USB Portable Cooling Fan” and the over heating freaking out issues vanished. It’s sitting on top of it on the low fan setting. I record a lot of Seinfeld episodes and it’s been working great for 7 months
Also when you say your WiFi is robust. What WiFi are you running? Like do you have a model number? Is it like a standalone WiFi router or is it part of a mesh system? Is it WiFi 5,6 or the new 7? Does the router use a smart connect feature where it combines the 2.4 and 5ghz bands together into one?
(worst feature by the way of any WiFi router. It never works right)
Does it contain mu mimo and OFDMA? These features are super important and I learned whether it’s a zoom video conference call or tablo, if your running 10,15 or even 20 wireless devices, that’s extremely hard for even a really good high end router to deal with. So features like those two I mentioned are important because it allows a router to feed multiple devices at the same time, where as, routers without that feature, tend to play a game of “pass the baton” around in circles to each device. And if multiple devices want the baton, somebody is getting left behind for a brief moment, and that can lead to latency or even connection drops.
I was running an asus rt AX56U but I recently did a slight upgrade to an AX58U and I have about 17-23 devices at any given time, lots of WiFi mouths to feed, and the Tablo doesn’t have a problem. But I also have the 2.4ghz and 5ghz channels separated, and I make a conscious effort to give priority devices that can only connect to 2.4ghz, like, smart devices, printers, the Tablo, and everything else connects to 5ghz.
It can also be that your in a busy area, and your WiFi channel is set to auto, and every time your WiFi channel changes from 1 to 6 or to 12, that can cause a random disconnect too. So using a piece of software you can get from the windows store called WiFi analyzer, you can find out what your neighbors WiFi channels are set to on both the 2.4ghz and 5ghz channels, and choose the one with the least amount of traffic on it, and set your WiFi channel to that one.
hopefully this was helpful. It may very well be a feature in your routers settings not configured very well.
