I am not really able to update to anything. The router itself says I have the most current one. 1.21EU. I tried to download the 1.33 NA and manyally choosing the bin fine with no luck. The same with 131EUB02. Do I have to do anything MORE than click update, let the PC upload the file and that reboot the router? Do I have to reset it or something?
I had the same problem while upgrading from 1.21 to a higher version. The problem is the 1.21 fw - it has some problems with the saving of settings. My solution was as follows:
1) reset and reboot the router
2) immidiately upgrade to the new firmware
and that worked with mine.
You may need first to upgrade to a lower version like 1.30EUB08 before upgrading to the newest one, 1.32EUB01.
