The Aruba 9240 controller at my site is already online and managing our wireless networks; what it still lacks is a fully functional guest-only captive portal. I need the portal turned on, configured and tested so that visitors are greeted with a branded login page and can sign in with a simple username-and-password flow. Scope of work • Enable and configure the built-in captive portal feature on the ArubaOS 10.x platform running on the 9240. • Restrict the portal to the guest SSID only; employee networks must remain untouched. • Implement local or external authentication (whichever you recommend for speed and security) that prompts for username and password. • Apply our logo and colour palette to the portal so it matches our brand guidelines. No other custom e...

The issue isn’t a full outage—pages eventually load, but streaming, video calls, and large downloads crawl. I’ve confirmed the problem persists across multiple devices, so it appears to be network-wide. Here’s what I need from you: • Run a structured troubleshooting session via remote tools (e.g., Zoom, TeamViewer, or your preferred platform). • Review my modem and router settings, firmware version, and channel/bandwidth configuration. • Guide me through speed tests and analyze the results to pinpoint bottlenecks—ISP, hardware, cabling, or Wi-Fi congestion. • Recommend and implement fixes: optimal DNS settings, QoS twe...

My WordPress site was hit by malware very recently, so the first task is to track down and remove every malicious file, script, or database entry without taking the site offline. Once the infection is gone, I need the entire installation hardened against future attacks—core, theme, and plugin updates, a properly configured Web Application Firewall, brute-force login protection, real-time scanning, and any other best-practice measures you consider essential. Turnaround is critical; I’d like actionable progress the same day we start and a fully secured site as soon as possible.
