GWN7610 update error

#1

I have problem with 7610. Few of 7610 are unpacked and have firmware 1.0.8… and after instaling them i can’t update. After clicking “Upgrade” i get message “Obtain server firmware failed!”, and in logs i have 2 rows, “Could not download http://firmware.grandstream.com/gwn7610fw.bin” and after that “user.err PROVISION: : unable to download firmware header”.
My assumption is that 1.0.8 is too “old” so i cant upgrade directly to 1.0.21, but i cant be shure, but i dont have problems with updating same Ap with newer version of firmware.
Is there solution for this problem? I cant manualy upload firmware, as far i know, and i cant find old firmware update path on web.

Thank you, support was rly helpful.

OK, solution for me was to setup local HTTP server, and from version 1.0.8 update to 1.0.9, then to 1.0.15 and then update from grandstream webpage

I also am finding myself upgrading a gwn7610 from 1.0.8.x

I was able to find 1.0.9 and upgrade to that but can’t find 1.0.10 etc or even the 1.0.15 you mentioned. Where can you find / get the intermediate versions of the firmware?

I got it from Gradnstream support.

Also, for other people who have same problem, try turn OFF option “Alow DHCP options 66 and 43 override” under upgrade menu. Somehow that helped me upgrade to newer version.
