Wi-Fi, ethernet and a mobile backup: what actually changes
Posted: Sat Oct 31, 2026 9:35 am
A scalper on Wi-Fi may not notice the problem until a bad moment. Wireless connections add variable delay and occasional drops that a cable doesn't. The average ping looks fine, and the worst-case ping tells the real story.
A wired connection removes that variability. Ping can be higher on average on a cheap line, but it's steadier, and steadiness often matters more than speed.
A mobile hotspot as a backup is a good idea, with a few cautions. Switching connections mid-session can drop the platform's link to the server. Mobile networks add more latency and more jitter. Carrier-grade NAT can cause odd disconnections.
A pair of habits help. Testing the backup in advance, with a live platform, not just a speed test. And knowing the procedure for open positions if the main link fails, which means having the broker's phone number handy and a mobile app logged in.
A speed test measures download capacity. A scalper needs low and consistent latency and no packet loss, which is a different thing.
