Spectra, triple, and quartic gauge couplings of the Higgsless model with gauge group SU(2){sub L}xSU(2){sub R}xU(1){sub B-L} defined in warped space are explored with a numerical method. We extend the equation of motions, boundary conditions, and formalism of multi-gauge-boson vertices to the Hirn-Sanz scenario. By assuming the ideally delocalized fermion profile, we study the spectra of vector bosons as well as the triple and quartic gauge couplings among vector bosons. It is found that mass spectra can be greatly modified by the parameters of QCD power corrections. Meanwhile, the triple and quartic gauge couplings can deviate from the values of the standard model to at least {+-}10% and can saturate the LEP2 bounds. We find the triple gauge couplings of ZWW can be 50% smaller than the unitarity bounds. The triple gauge couplings of ZWW is 20% smaller than the unitarity bounds, which might challenge the detection of Z via s channel at LHC if m{sub Z}>500 GeV.
