Good morning, my newly purchased OTD500 with the current firmware shows a modem temperature of 90 degrees or more. Can this be, or is this a bug? Dirk [Bildschirmfoto 2026-06-01 um 08.56.00]

Under load, the modem heats up to 98°C. Parts of the frequency bands—in my case, 5GN1—are disconnected. Occasionally, the modem completely loses its network connection and restarts. It is currently installed indoors at a room temperature of 22°C. Without any load—i.e., no downloading or streaming—…

Hello, Thank you for the detailed information. Before proceeding, I would like to ask a few additional questions: Has the device been reaching these temperatures since it was first powered on, or did the issue start at a later point? Were any configuration changes, firmware updates, or environme…

Hi Povilas, i did also add some new screenshots and informations to my post from today

Can you maybe post your FW and Modem FW informations ? What HW Version and Batch is your unit ?

I don’t have a OTD500 myself, mines a RUTX50. Mt question was rather generic. Is it possible that the recorded temperature is incorrect? At these temperatures can you pick the router up and firmly hold it in your hand without letting go and dropping it!? I’m guessing it would be almost impossible t…
