As per online researches, For NIT patna there are good wifi facilities. This installation is periodically checked and updated as required. Internet access is provided by BSNL (1 Gbps), PGCIL (100 Mbps), Railtel (10 Mbps). But there are still some areas in the hostel where internet connectivity has a problem.

I hope this can help you. All the very best for your future endeavors!
