The Xiaomi Mi 4A Dual Band Wireless Router allows you to reach 300Mbps over the 2.4GHz band and 867Mbps over the crystal clear 5GHz band, the max wireless speed is up to 1167Mbps over both. The 2.4GHz band offers transmission over greater distances, with better coverage and better penetration through walls, while the 5GHz band adopts 802.11ac technology giving you less interference and higher speeds for a smoother experience watching HD videos and playing multiplayer online games.

The Mi Router 4A supports Smart Connect, offering 2.4GHz and 5GHz bands under one Wi-Fi name. This allows you to have no more confusion over which Wi-Fi network to connect to 2.4GHz and offers better performance through walls, while 5GHz provides higher speeds. The optimal frequency band is also automatically selected by a dual-band terminal.

The router comes with 4 external antennas so that the signal can travel through walls better. 4 external omnidirectional antennas, which are precision tested, and with a carefully designed internal structure and configuration greatly improves transmission performance, even in complex environments. It also features dual cooling fin heat sinks for better system stability and cooling. A specially treated metal substrate is combined with nanomaterials boasting exceptional thermal radiation features. It offers both excellent heat absorption and heat dissipation capabilities to effectively lower the chip temperature and provide improved system stability.

A Comprehensive Pocket Guide to Christian Living
Format: Paperback
Looking for a book on discipleship? Not sure what discipleship is, or how it relates to Christian living? Want to learn more about how God grows us and wants us to grow? May I recommend Mapping Discipleship, a 2025 release from Faith Publications by Charlie Carter, co-host of The Thinklings Podcast (my favorite podcast). I pre-ordered my copy and read it shortly after its (early 👏) arrival. I ended up using it as my devotions, taking extra time to read the suggested passages and think through the reflection questions. Some pros of this book are -its small, short size: the chapters themselves are short, making the book more of a "pocket guide" than an intimidating, extensive treatise. -its catechism style: each chapter's title is a question that the chapter itself answers with Scripture, personal examples, illustrations and analogies, and practical application. Each chapter builds on the next, so start at the beginning. -its organization: the division of chapters into 3 parts (recognition, renewal, and results -- not exact) makes for a logical progression easy to follow and to implement. -its depth: though small, Mapping Discipleship packs a big punch in the way it lays out and digs into foundational truths of Christian living and how we grow. Deep thoughts and rich language. Chew slowly. Mapping Discipleship's only con (for me) is also its pro: its length. A few places I would have loved more fleshed-out discussion and maybe some additional resources. I'd love to share some of the quotes that impacted me, but I already lent my copy out to a friend. 😅 Just get your own copy -- you will be challenged and blessed!

A Genuinely Good Guy & A Genuinely Fun Read
Format: Hardcover
A prison diary with optimism, realism and humor. You can read this book in its daily snippets, but you won't want to put it down as the daily drama unfolds. Each story leads up to the next in a riveting account of gritty survival. Peter is a man I genuinely would like to meet some day. Every once in awhile we get blessed with a public servant who has a heart of gold. Someone who doesn't just look after their own selfish interests, but cares about the affairs of others. Peter proves to be that man. Injected into a jail system with malice as a political prisoner, we find Peter busy helping others. When life gave him lemons, Peter chose to make lemonade for others. He discovered everything that seemed hopelessly mucked up in the prison system. So Peter, the ever-observant statistician, dug deep into the root causes of the massive dysfunction. He then began detangling each individual man's predicament with precision. And love. He genuinely cared about the prisoners and their families, their lives and their future. And when he left, he continued to work to change things for the better. That is honorable and commendable.

Well written
Format: Kindle
Navarro writes "postcard" style short chapters. Easy to read with a dash of humor in each. His prose flows well. I was captured by his efforts to improve his situation along with fellow inmates. Quite enjoyable.
