I would recommend sending in a trouble ticket email to TabloSupport. It’s possible that your Tablo needs to be replaced.
Are you doing a channel scan each time you look at it, or are you just looking at the results from the first channel scan? It doesn’t update dynamically (though I hope the Tablo folks get around to that), so it may look like every channel has 5 green dots when it really doesn’t. Just run another channel scan to see the up-to-date results.
You have covered most of the troubleshooting methods already.
On September 3 the same thing happened to me after working flawless for 4 months. Tried to watch live TV on iPad, got weak signal on every channel. A bunch of failed recordings. Unplugged Tablo plug back in, closed iPad app restarted, resync. now working again. All 3 of our iPads acted the same way.
we’re having the “Error - weak signal” issue. has worked fine for several weeks, now there several channels that won’t come thru. unplugged Tablo, checked cables. checked firmware, it’s up to date.
