TL-ER5120: Bandwidth based balance routing does not work
Hello,
I am running a TP-Link TL-ER5120 router with 4 WAN connections, two fiber and two 4G LTE. I've been trying to enable bandwidth based balance routing, but it does not seem to work. WAN3 and WAN4 are consistently under-utilized, even though I have set the second and third highest bandwidth for those WAN's. Could some-one help me? Do I have something mis-configured?
My setup is as follows
Hardware Version: TL-ER5120 v3.0
Firmware Version: 3.0.2 Build 20180125 Rel.35267
WAN1: 300Mbps fiber connection, uses PPPOE. Upstream and Downstream bandwidth set to 300,000 in the WAN config page
WAN2: ~10Mbps 4G connection. Upstream and Downstream bandwidth set to 75, 000 in the WAN config page
WAN3: ~10Mbps 4G connection. Upstream and Downstream bandwidth set to 100,000 in the WAN config page
WAN4: 100Mbps fiber connection, uses PPPOE. Upstream and Downstream bandwidth set to 200,000 in the WAN config page
Enable Load Balancing is checked in the Transmission->Load Balancing->Basic Settings page
Enable Application Optimized Routing is unchecked in the Transmission->Load Balancing->Basic Settings page
Enable Bandwidth Based Balance Routing is checked in the Transmission->Load Balancing->Basic Settings page, with WAN1, WAN2, WAN3, WAN4 selected
There are no Link Backup Rules
Online Detection for all wans is set to auto
There are no active Policy Routing rules
Enable Bandwidth Control is not checked, there are no Bandwidth Control Rules
Actual WAN usage for the most recent few days is
