Hi. I recently uploaded the TL-WA701ND(EU)_V2_160620 firmware but I don't like it; the "Antenna Alignment" feature disappeared and the wifi networks' signal strenght is less accurate than before; I honestly prefer the previous one. However when I upload the TL-WA701ND_V2_140324 firmware I get this message:

Error code: 18005
Upgrade unsuccessfully because the version of the upgraded file was incorrect. Please check the file name.

Could someone help me, please?
