It seems like LEDE supports TP-LINK TL-WR941N, but not the TP-LINK TL-WR941HP.
Is the LEDE firmware for TP-LINK TL-WR941N is also compatible for the TL-WR941HP?
When LEDE will support TP-LINK TL-WR941HP 450Mbps?
Is it built on Realtek SoC?
No, not Realtek but Qualcomm Atheros TP9343 -> Specs: https://wikidevi.com/wiki/TP-LINK_TL-WR941HP_v1.x
