I have a new Tablo Dual and 2 Roku Expresses. One Roku in the living room connected by HDMI and on the Wi-fi network. The second Roku is in the bedroom connected by HDMI and on the Wi-fi network. The Tablo is on the Wi-fi network.
I have a strong antenna signal on the 2 channels that I need to watch off air (Fox and NBC) on the Tablo.
I can watch Live tv on the living room tv, but the bedroom tv says “signal too weak”.
Is the signal too weak on the Wi-fi? The Roku’s are connected to the same network.
Roku Express built before 2022 only had 2.4 GHz WiFi available. It’s slower and more susceptible to interference than 5 GHz WiFi, but it does have longer range.
If the Roku Express’s are connecting over 2.4 GHz WiFi, that might be your issue. We had a similar issue with a Roku Priemere (streaming in general, don’t have TabloTV yet) until we redid the WiFi with an access point closer to it.
I think very recent RokuExpress and Priemere are 5 GHz WiFi capable and I know Roku Ultra is 5 GHz capable and 5 GHz does have better bandwidth and less interference, but also has much shorter range.
Can add that recent Roku’s with some form of USB (separate Type-A port or microUSB for power) can use some USB-to-Ethernet adapters. I have an Express 4K+ with an Amazon Fire TV adapter. Some adapters will need an OTG cable, others are designed for streamers and are mostly plug-and-play.
You posted in the TV Connected / HDMI - yes they keep their naming confusing. Presuming you have this type tablo.
Here tells you which Roku’s are supported. Note: not showing Express
