Why do you need an ipk, the 8188 is available in the feed (menu, plugins, software management, advanced options, package management).
p.s. the V2 uses the rtl8188eu chipset, which requires both kernel-module-r8188eu and firmware-rtl8188eu.
sorry the expert user is not active so i couldn't find advanced option.
i installed kernel-module-r8188eu but couldn't find rtl8188eu only rtl8187eu
please advise
