Recommendations

Via Wi-Fi, we recommend using with business routers, such as TP-Link Archer or Cisco models. Prioritize use on 5 Ghz frequencies that suffer less interference and drops than 2.4 Ghz frequencies and check signal strength.

Mesh network equipment can also be used, which amplifies the signal and allows transit between equipment without disconnecting the user.
