We study the phenomenology of the 4-site Higgsless model, based on the SU(2)_L × SU(2)_1 × SU(2)_2 × U(1)_Y gauge symmetry, at present colliders. The model predicts the existence of two neutral and four charged extra gauge bosons, Z_(1,2) and W±. In this paper, we focus on the charged gauge sector. We first derive limits on W1,2-boson masses and couplings to SM fermions from direct searches at the Tevatron. We then estimate at the 7 TeV LHC the exclusion limits with the actual L=1 fb?1 and the discovery potential with the expected L=10 fb?1. In contrast to the minimal (or 3-site) Higgsless model which predicts almost fermiophobic extra gauge bosons, the next-to-minimal (or 4-site) Higgsless model recovers sizeable W_(1,2)-boson couplings to ordinary matter, expressing the non-fermiophobic multiresonance inner nature of extra-dimensional theories. Owing to this feature, we find that in one year from now the new heavy gauge bosons, W± , could be discovered in the final state with an electron and large missing transverse energy at the 7 TeV LHC for W1,2-boson masses in the TeV region, depending on model parameters
