Good night, I have the TL-WR820N router, with the version below

Hardware Version: WR820N 1.0 00000000

Firmware version: 1.0.2 Build 190905 Rel.42436n

And on the website there is the version TL-WR820N (BR) _V1_190905 09-09-2019 I would like to know if this version is more recent than the one I have above.

NOTE: I want to update the firmware to see if the wifi stabilizes, because I am having a low connection via wifi and when I use the internet cable cabling is much better.

Also, the light on the WAN router is constantly orange instead of green. Thank you very much in advance.

I tried to update to version TL-WR820N (BR) _V1_190905 09-09-2019 and I got the error "could not update"
