Hello!
I just came across the page:
wiki.openwrt.org/toh/d-link/dsl-2740b
... and something does not seem right. The value that can be found at "Current Release" states version "12.09", but all installation links point to version "15.05".
(e.g. downloads.openwrt.org/chaos_calmer/15.05/brcm63xx/generic/openwrt-15.05-brcm63xx-generic-DSL274XB-C3-squashfs-cfe.bin)
I don't know which information is correct now. I don't want to brick my device by using the wrong version...
Thanks for any help!
