Do you mean the Ethernet cable? Please be more specific in explaining your problem. Post a picture if you can.

Try a different cable, try a different port on the router/switch it's connected to. If neither thing helps, you can buy a network card for maybe $15-20. Would be messier in a laptop as you'd need to use an external one like https://www.amazon.com/dp/B00ET4KHJ2/ref=pd_lpo_sbs_dp_ss_3?pf_rd_p=1944687722&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B0012P26ZO&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=54V31HRJSTTWC6RH9MZH
