setup set up done but client 0 why? the steps are all ok

[oibaf]

I managed to configure the wifipineaple everything ok works I also downloaded a module .... but ... the problem is that it can not capture anything ... always marks client 0 but I repeat all the steps have been done well and the wfpinepple appears in the PC with the wifi signal

does anyone or the administrator have advice or videos for this step? thank you all
