+**What steps do you follow when troubleshooting a network issue?**
+  - Clearly understand the user experience regarding support
+  - Separate the support metric between the Internet service and the WLAN connectivity by the user.
+  - Verification of the user's Wi-Fi card.
+  - Verification of the channel and connection frequency by the user and/or the WLAN system per AP, which is complying with the rules of non-overlapping and non-activation of the DFS UNII 2 ext channels.
+  - Comparative performance calculation, compared to the characterization of the AP to which the user is connected.
+  - Analysis of materials that focus on absorption and dispersion of photons between wavelengths of 5 cm, 6 cm and 12.5 cm.
+  - Roaming analysis, power, sensors and channels.
+  - Verification of 802.1x/AAA service functionality; certificates, auto-vlan-qos, dictionaries, others.
+  - DNS, DHCP scope service, static ip, local firewall, local EDR, perimeter firewall rules, perimeter DPI, perimeter ACL/WCF, return routes on the side of the UTM or the operator's router, opening of the minimum management ports of the CMS - C/PANEL (2083, 443, other udp) for the management of APs.
+  - Verification of the configuration of the Ethernet ports of the AP or devices that intervene in the verification process, which comply with the minimum traffic rules (802.1Q/802.1D, 802.1P, QoS, DSCP, LLDP, ACL, Broadcast storm control, others)
