Hi
What is the best way to upgrade my router to never version ( I already have latest version installed but want to know for the future ) ?
I have seen different guidance which is a bit confusing.
Can I do:
1) restart router
2) backup settings ( just in case)
3) upgrade to latest DD-WRT version ( without resetting to difficult settings )?
4) restart router - just in case
or I always need / have to reset router to default settings, upgrade ,then configure all WiFi, other setting, etc. from beginning ?
Generally, do not reset. Run into problems? Reboot. Cold boot. Troubleshoot, update, fix a config? Maybe.
Depends how old previous build(s) were and resulting config generated. Do not restore old build backups.
Build was over a year old? Yeah, recommend starting over. Which reset method depends hardware model.
Common reset methods: GUI factory defaults, hardware reset (model specific) or nvram erase && reboot.
The rest is up to you. Router has a very long uptime? Wouldn't hurt to reboot then allow 20 minutes or so.
Have an advanced configuration with USB connected device? Maybe unmount, or disable USB temporarily.

Router details:
Firmware: DD-WRT v3.0-r48646
Model: ASUS RT-AC87U
What I am wondering is, currently I have the newest version installed. However, when new version will be released let's say: r48647.
What is the recommended procedure to upgrade to "the latest and greatest" from previous one?
Over time I’ve found that the safest way to upgrade is through a telnet session not using GUI. After connecting to the router:
- “cd /tmp”
- run “curl -O path to desired image incl file name ”
- run “write name of desired image linux”
- reboot
If upgrading from a reasonable recent build, no need to reset settings _________________ Netgear R7000 on Build 55109

for the write command I add the & symbol at the end; example...
- run without quotes “write name-of-desired-image linux &”
This way the write command will run in the background even if your telnet or ssh session disconnects which may happen on remote sites. _________________ Home Network on Telus 1Gb PureFibre - 10GbE Copper Backbone
