Need Advice on Upgrading Business Wireless Networking

Last month, our office started facing random internet dropouts during client meetings, and it became frustrating for the whole team. We realized our old setup couldn’t handle the growing number of devices anymore. After researching different business wireless networking options, I’m considering upgrading to a more reliable system with better coverage and security.

Has anyone here recently upgraded their setup? I’d love to hear real experiences, recommended equipment, or mistakes to avoid before investing. Trying to make the right choice without overspending.
