I have a suggestion for improvement.
Buffalo WSR-2533DHP is identical to WSR-2533DHPL, but cannot be searched in Table of Hardware.
Adding WSR-2533DHP to Table of Hardware would prevent users from giving up and avoid confusion.
you should submit an alias PR, like https://github.com/openwrt/openwrt/pull/17615, then it'll pop up everywhere, firmware-selector too.
I could no open PR.
Pull request creation failed. Validation failed: must be a collaborator
based on google hits, seems you need to clone the openwrt repo, and submit it from there.
I give up on this one.
I would like someone with the collaborator authority to submit the alias PR.
