Problem:
- ISP provides 20 Mbps
- Speed test on XG shows download at 20+ Mbps
- Clients hover between 7-10 Mbps - never over ~10 Mbps.
Troubleshooting steps:
- Rules: Created plain rule with no checks enabled, no traffic shaping. Verified in Policy Test that this rule is used.
- Traffic shaping (QoS) settings - Set Total available WAN bandwidth to max (2560000).
- Traffic shaping (QoS) settings - Disabled "Enforce guaranteed bandwidth"
- Traffic Shaping - Created max throughput shaping rule and applied to the plain rule.
- Services - Disabled AV service
- Services - Disabled IPS service
- Client-side bandwidth - never exceeds ~10 Mbps
- XG CLI: Performed download test (100 MB file) on the XG device: gets the maximum of 20+ Mbps
- Metrics: CPU <25% during download tests.
- Metrics: RAM usage ~35% (2.5 GB), free ~3.5 GB)
- Console bandwidth monitor shows the same bandwidth on WAN and LAN interfaces.
- Rebooted XG
Rules:
- For troubleshooting, only one rule - any-any. No checks, shaping, etc.
Shaping
