Living on Rakuten Mobile: Why 2.4 GHz Made My Home Wi-Fi Stable

Fiber-Free Home Internet That Actually Works

My apartment runs entirely on Rakuten Mobile (UN-LIMIT VII) plus the SIM-free +F FS050W mobile router. Work calls, streaming, and smart-home devices all run through it. The secret to a stable connection? Stick with 2.4 GHz instead of 5 GHz.

The Base Setup

  • Carrier: Rakuten Mobile (strong reception in my building)
  • Router: +F FS050W supporting dual-band Wi-Fi
  • Power: USB-C adapter, parked permanently on a shelf

Insert the nano-SIM, disable sleep mode, and it becomes an always-on home gateway.

What Went Wrong With 5 GHz

I started on 5 GHz to chase faster speeds but hit constant issues--pages that stalled, video buffers, and signal drops the moment I moved to the bedroom. Concrete walls do not play nicely with higher frequencies.

Switching to 2.4 GHz Solved Everything

Once I toggled the router to 2.4 GHz, the connection stayed solid across every room. Speeds dipped slightly on paper, yet real-world performance improved dramatically for blogging, video calls, and Prime Video.

Quick recap:

  • 5 GHz = higher throughput, weaker range, struggles with walls.
  • 2.4 GHz = slower peaks, but greater reach and obstacle penetration.

In multi-room apartments, range wins.

Why I Recommend the +F FS050W

  • Touchscreen band switching in seconds.
  • USB-C power keeps it online 24/7.
  • Optional sleep mode so it never shuts off mid-download.
  • Easy-to-read status for signal strength and monthly data.

Tips Before You Ditch Fiber

  • Choose a router that lets you manually select 2.4 GHz or 5 GHz.
  • Confirm USB tethering and external power options for flexibility.
  • Future-proof with 5G support if coverage is expanding in your area.

Final Thought

Running a household on mobile data is viable--just optimize the Wi-Fi band for your layout. Test both frequencies, note where signal drops, and pick the one that fits your space. My Rakuten Mobile setup has been reliably smooth ever since.
