If you are looking for an expert to configure Aruba ClearPass, fix Wi-Fi problems, troubleshoot wireless authentication, improve wireless performance, migrate to Aruba, or resolve switching and VLAN issues, I can help. I am a highly experienced Network Consultant and HPE Aruba specialist with 13+ years of experience designing, configuring, troubleshooting, and supporting enterprise wired and wireless networks. My core expertise includes: • Aruba ClearPass configuration and troubleshooting • 802.1X, MAC authentication, EAP-TLS, PEAP, RADIUS, TACACS+ • Aruba Wireless Controller, Mobility Conductor, and AP configuration • Aruba Central and Aruba Instant AP deployment • Aruba CX switch configuration and troubleshooting • VLANs, trunks, access ports, spanning tree, ACLs, and role-based access • Guest Wi-Fi, captive portal, BYOD, and certificate-based authentication • Wireless troubleshooting for slow Wi-Fi, disconnections, poor roaming, interference, and weak coverage • RF optimization, channel planning, transmit power tuning, and high-density Wi-Fi design • Aruba AirWave monitoring, alerts, and network visibility • Cisco to Aruba migration and multi-vendor network integration • Network design, documentation, implementation, and handover Common problems I can help fix: • Wi-Fi is slow, unstable, or unreliable • Users or devices keep disconnecting from wireless • ClearPass authentication is failing • 802.1X, RADIUS, or certificate authentication is not working • Guest Wi-Fi portal is not redirecting correctly • APs are not joining Aruba Central or the controller • VLAN assignment is failing • Wireless roaming is poor • Coverage is weak in certain areas • Aruba switch configuration is not working as expected • Network migration from Cisco to Aruba requires expert guidance I have worked on large-scale enterprise, campus, healthcare, education, retail, and hospitality network environments, supporting both greenfield deployments and complex migration projects. My approach is practical, structured, and outcome-focused. I review the current configuration, understand the issue, identify the root cause, and provide a clear solution with documentation where required. I can assist with remote troubleshooting, configuration review, implementation planning, ClearPass policy design, wireless health checks, RF optimization, Aruba CX switch configuration, Aruba Central support, and post-deployment validation. If you need an Aruba ClearPass, Aruba Wireless, Aruba CX switching, Cisco networking, or enterprise Wi-Fi troubleshooting expert, I would be happy to help.
