802.11n 300 Mbps and 802.11ac 867 Mbps Wireless Routers in Real-World Report

Because QNAP Virtualization Station and other services needs more and more bandwidth, I bought a Asus RT-AC1200G+ to replace RT-AC51u and netis WF2190 to upgrade to 802.11ac 867Mbps. Expecting to replace my wired  Gigabit Ethernet.

Things doesn’t go well. I experience random reboots with Asus RT-AC1200G+ but learn the complexity of wireless implement. While working on it, an Edimax engineer give me a hand and send me an Edimax BR-6478AC V2. Dolly from Asus also provides me an unpublic firmware to test. And all the commends on post. Without their help, I couldn’t get my wireless working properly.

Therefore, I decide to write this post to share my real-world experience. It will be update continuously.

Let’s begin from knowing my devices, network map, and placement:

Setup a Surveillance System to Proof Crash of Asus RT-AC1200G+

I write this post is related to ASUS ORDER CUSTOMERS TO PROVIDE VIDEO PROOF ON A CRASH ISSUE THEY HAVE REPRODUCE THAT HAPPENS ON THEM on 1st RMA: From 2017/5/15 till Now section in Asus RT-AC1200G+ Random Reboots Automatically.

Here I use DCS-930L Wireless N Network Camera from D-Link and AS-5102T from Asustor as an example to setup surveillance system and keep track of the light on Asus RT-AC1200G+. I will update with other models in the future.

This is a sink cost owning Asus products when you ask for repair.

Files Contain Windows Invalid Characters Transferred from QNAP to Asustor Using rsync

I want to copy files from QNAP TS-119P II to Asustor AS-5102T directly. There are many solutions: including ftp, rsync, or mount a shared folder.In my case, rsync is the easiest solution.

TS-119P II runs QTS 4.3.3 while AS-5102T is ADM 2.7.1. Details steps might be different if you are using different firmware versions.

I will also talk about invalid characters in names and how ADM handle it. A must read for non-Windows users.

How to Solve Thecus D0204 and JMS539 Auto-Disconnect Issue

Thecus D0204 is a Direct-attached storage (DAS) supports two 2.5″ hard drive in RAID 0, 1, JBOD, and two individuals. According to “USB 3.0加持，Thecus D0204小DAS跑得快” on T客邦, it use JMB390 for RAID and JMS539 for SATAII to USB 3.0 bridge.

My problems is it will automatically disconnect and reconnect immediately with OSX. But I was wrong, there are already many posts about the same issue. It’s due to the bugs in JMS539 according to “[心得] Mukii3.5吋硬碟外接盒起死回生紀錄” on 批踢踢實業坊.

QNAP TS-119PII with Different Wireless Device on Mac OSX File Transfer Performance Report

I did this test because uploading files to NAS is incredible slow today. The only different is my new WF2190 last week. I spends hours to do a full check of my NAS and eventually find out it is related to driver. I didn’t uninstall D-Link DWA-171 rev A1‘s Realtek driver before installing netis WF2190. During the test, I also learned the difference of my WiFi devices.
