Hello,
I am sorry if this is a noob question.
I have an "old" MR18 wifi router that has not been connected for a while.
I wanted to find which firmware version is installed but when I connect to http://10.128.128.128 , the firmware information is "empty"
How can I retrieve the firmware information please ? (I am not sure to know how I can do with busybox).
Thanks for your help
From https://openwrt.org/toh/meraki/mr18#installation
You can find which version of the firmware is on your device by running the command “odm fw_version” on the serial connection.

Thanks a lot for your prompt answer.
Unfortunately, I dont have a serial cable; is there another way to retrieve this information ?
You'd have to ask Cisco (the OEM).
Damn, I am so noob.
What do you mean by "The OEM" please ?
An original equipment manufacturer (OEM) is generally perceived as a company that produces parts and equipment that may be marketed by another manufacturer.
However, the term is also used in several other ways, which causes ambiguity. It sometimes means the maker of a system that includes other companies' subsystems, an end-product producer, an automotive part that is manufactured by the same company that produced the original part used in the automobile's assembly, or a value-added reseller.

Thank you; so I understood correctly but how Cisco can give me the information as the MR18 is not connected anymore ?
You asked:
So I suggested you ask Cisco for a second method.
We don't know Cisco's software
Cisco made the software (they are the OEM)
You won't use a Serial cable (because you don't have one)
So, only they would definitively know how otherwise
You have this
Ya, ask Cisco how to find out the firmware.
Is it running OpenWrt?
https://openwrt.org/toh/meraki/mr18
Try ssh to it.

Thank you
No, it's not running OpenWRT yet.
I want to install OpenWRT but first I want to find the firmware version installed to identify the best method to do so.
It seems that I need a UART cable for that even if I am able to connect in web to the router.
Definitely - you'll need a serial cable to install anyway; and if not included, a 5V to 3.3V TTL Serial adapter .
lleachii:
5V to 3.3V
Thanks a lot for the information ! I didn't know that !
I just bought that : https://fr.aliexpress.com/item/33040891991.html?spm=a2g0s.9042311.0.0.31056c374Tax1t
It is written that on the description (not sure to understand this english ! :p)
"Note: 3.3V and 5.0V output is set (this is the power supply to the microcontroller, upgrade machines do not need the small plate) unplugged from the computer, set the jumpers to take, do not live to avoid damage to the equipment."

I don't clearly understand...
...but I think it's warning you not to connect Positive (+) to the board.
Only use three: TX, RX and Ground/Earth.
You still need to use a 3.3.V TX/RX line/adapter!
Have you had much luck? I’m looking to do the same.

If you want to find out which firmware is installed, then see above: MR18 - How to find which firmware is installed?
tl;dr
Get a serial cable
open your MR18 and attach the serial cable
establish a serial connection to your MR18
on the serial console, execute the command odm fw_version
