I have a new 4 tuner Tablo which I just started using last week (Sept. 24, 2016). It seems that overnight it "gets lost" ?? and cannot be seen by my router. Very annoying! As above, the only solution so far is to disconnect / reconnect power to the Tablo, It reconnects again within about 30 seconds after power-up, and all is good. Is this a "sleep mode"??
Other smartphones, tablets or PCs on the same network do not exhibit this issue.
Hardware & connections:
Antenna (attic): Clearstream 4v
Modem: Arris SURFboard SB6183 DOCSIS 3.0
Router: D-Link DIR 850-L
HD: 1TB Western Digital Elements Portable External Hard Drive
Streaming Device: Roku Streaming Sticks (2)
To eliminate ANY possible wifi hiccups, I ran HDMI extension cables from each TV (2) into the utility closet where the modem, router and Tablo are located. The Roku sticks are about 2 feet from the other devices. I get BEAUTIFUL streaming and video quality. The only issue at this point is the nightly Tablo disconnect!
I have NOT tried the above suggestions yet (DHCP; static IP, standing unit on it's side). I will try tomorrow and post back.
On an unrelated note - the hardware remote for at least one Roku stops working over night also!! However, the phone app (Android) works fine. AND more puzzling - after using the phone app, the Roku hardware remote seems to automagically wake up!
Not a good start for my cable cord-cutting experience...
