Tethering with Asus RT-AC1200G+ Drops Automatically


I bought a new Asus RT-AC1200G+ to replace my RT-AC51U for better signal and Gigabit Ethernet. It’s much faster to copy files to/from QNAP TS-119PII now. But I notice it drops internet connection several times a day, I am sure there is nothing with my tethering device as described in “Android USB Tethering Drops and Data Usage Crashes, try Reset“.

RT-AC1200G+不定期重啟 has discuss the same issue. It seems related to bugs in current firmware (3.0.0.4.380.3310). I have to download version 3.0.0.4.380.4089 released on 2016/11/14 from RT-AC1200G+ Driver & Tools and upload via [Administration] → [Firmware Upgrade] tab. It will begin to flash and reboot automatically.

My RT-AC51U works without dropping for 3 days after the upgrade but still generate some warning in system log. I will keep an eye on it and update this post.

Restore Your Lost Tabs in Toby and How to Prevent It


Toby is a tab management extension in Chrome. It helps me to save current session as a new a group and close all tabs. Manage saved tabs by groups. Re-open a tab or a group quickly. Not only organize my working tabs more efficiently but also save memory and help my OS X more responsive. I also enable the “Sync to Google Drive option to make a backup of my groups.

Everything is perfect until I turn on “Sync to Google Drive on my Acer Chromebook 15 with the same Google Account. It didn’t sync back from Google Drive but replaced with the new default tab groups. The Chrome on OS X detects the new version on Google Drive and replace my local version. All my saved tabs are gone.
