Top 10 Causes & Instant Fixes (Start from the Top)
1. Unstable Internet (Most Common by Far)
Even 5G can spike in latency or packet loss.
- Run a speed test (fast.com or speedtest.net) — need ≥8 Mbps upload + ping ≤60 ms
- Switch to 5 GHz Wi-Fi or mobile data
- Restart router or move closer to it
- Close background apps using bandwidth (Netflix, downloads, etc.)
2. Wi-Fi Congestion or Interference
- Switch from 2.4 GHz to 5 GHz band
- Turn off nearby Bluetooth devices or microwaves
- Use a wired Ethernet connection if possible (best quality)
3. App or Browser Cache/Outdated Version
- Update the Dial91 app (or refresh browser tab)
- Clear cache & cookies if using web version
- Force close and reopen the app
4. Device Overheating or Low Battery

6. VPN or Firewall Blocking
