Assalamualaikum wa rahmatullahi wa barakatuhu, Is working for networking company (they manufacture wifi etc) permissible, if there is a chance as a part of job you might have to help clients which might be banks etc, set the device up and troubleshoot it?

Ustadh AbdulAziz al-Haqqan

It is allowed to work this job, but if a project starts and it is a riba bank, then don't get involved in that project.
