There are a few ways to try and address this.
- Moving the Hotspot to a different window, or higher floor if possible. Metal window screens can also affect RF, so if those can be removed it may improve the signal.
- Placing the Hotspot outdoors. Some building materials in the surrounding walls can block RF. For example, Stucco buildings have a layer of metal wire, so placing at least the antenna outdoors would help with that. Look for IP-66 Waterproof cases if you’re intending to place the Hotspot outside. You can purchase these from mouser.com, amazon.com, or most hardware stores.
- Some newer high-rise buildings have a UV protective layer on the outside of the building glass that is known to block and interfere with radio signals. If this occurs, you could try moving the Hotspot outside (in a weatherproof case), or purchase an outdoor antenna so it can bypass the glass.
- Check and see if you’re on a relay by searching for it here. If a Hotspot being relayed, it means its internet connection is being relayed through another Hotspot on the Network. To take the Hotspot out of relay requires opening ports on your internet router (to port 44158), and may require some additional work beyond opening ports, like setting a static IP, depending on your router manufacturer. This can help it better maintain sync and properly send/receive transaction receipts for Beacons and Witnesses.
If you find your Hotspot relayed, You may need to check with your internet router manufacturers documentation for the specific steps, as each one has a different process for opening the ports.
