Synology flag one of the drive to be critical
After running extended SMART test, all is good and no bad sector.

So you would like to reset the status and add back the disk.

** Find out your drive model and serial number

1. Storage Manager → HDD/SSD → Select critical disk → Deactivate Drive
2. unlplug your drive from Synology
3. Control Panel -> Terminal & SNMP -> Enable SSH service

Follow the WORKAROUND:
  1. Add a comand to /etc/rc.local, add the following line above "exit 0": 
        setpci -s 00:1c.2 0x50.B=0x41
  2. Add the same comand to /etc/apm/resume.d/21aspm (which does not exist yet):
        setpci -s 00:1c.2 0x50.B=0x41
  3. Add the following to /etc/modprobe.d/sdhci.conf:
          options sdhci debug_quirks2=4
  4. Re-generate initrd:
         sudo update-initramfs -u -k all
  5. Reboot or reload sdhci module:

1. install transmission-daemon and samba
2. mkdir /transmission-share
3. sudo usermod -a -G debian-transmission $(whoami)
4. sudo chgrp debian-transmission /transmission-share
5. sudo chmod 770 /transmission-share
6. sudo vim /etc/transmission-daemon/settings.json
  change download_dir to /transmission-share
  change umask from 18 to 2
  append rpc-whitelist with 192.168.*.*

It is imperitive that you need to change 2 files in order to prevent transmission to overwrite your changes.
The default credential is admin:admin

1. SSH into your synology
2. edit /var/packages/transmission/target/var/settings.json to change the username and password
3. edit /var/packages/transmission/var/settings.json to change the username and password

To understand how the username and password get inserted into the settings.json, you can read /var/packages/transmission/scripts/service-setup

Under lspci -vv, I saw my wifi card bcm43228 is using wl module, but it is working weirdly, so I go inspect dmesg and found:
[   17.135645] wl: module license 'MIXED/Proprietary' taints kernel.
[   17.135648] Disabling lock debugging due to kernel taint
[   17.137273] wl: module verification failed: signature and/or required key missing - tainting kernel
[   17.227089] wlan0: Broadcom BCM4359 802.11 Hybrid Wireless Controller 6.30.223.248 (r487574)
[   17.315644] wl 0000:03:00.0 wlp3s0: renamed from wlan0

linux is loading the wrong device for my wifi card.
so I search online and found https://ubuntuforums.org/archive/index.php/t-2209676.html
