Slow Internet Speed Even with MultiWAN Load Balancing

[mush2020]

I have 5G router with 1Gbps Internet speed, with LAN directly connected to 5G router internet speed is between 800-950Mbps. If test is performed through LAN port of Opnsense max speed i could get is around 101Mbps(Down) and 109Mbps(up).
5G router and Opnsense are connected via L2 Managed Switch.
Additionally, i have 2nd ISP fiber with 100Mbps speed.
Configured Load Balancing with MultiWan (no improvement in speed)
IPS = Not enabled
Unbound = Enabled

Currently, i could see in GW status 5GWAN is offline. Not sure why its offline. Attached status screen print.

Need help to fix the issue

Thanks

check setting of your 5G line, is it marked "offline"
can it ping 8.8.8.8? maybe change it to 1.1.1.1 just to try

5G router and Opnsense are connected via L2 Managed Switch.

are you sure it is configured correctly?

you can use it directly? imean directly connecting a laptop to your modem?

Thanks Tong2x,
I rebooted both opnsense and router. Now both GW status is online.
Just to test i disabled unbound and run the speed test. The speed is improved 467Mbps
In Unbound under Misc i was using Clearbrowsing DNS IPs 185.228.168.168@853 and 185.228.168.168@853

Is Unbound or clearbrowsing DNS is reducing speed. I cannot find the root cause.

I'm thinking to use NextDNS and disable Unbound. But not sure Port Forwarding rNAT rules to disable as i was using while Unbound is in use to prevent DNS baypassing.

Any help to troubleshoot this issue.

I'm still having issue with internet speed.
For testing i have single 5G WAN.
As seen in attched screenprint Opnsense speedtest Report max down speed is 94.33Mbps
If i connect laptop directly to 5G router, down speed is between 800-900Mbps
During test
Unbound=disabled
IPS=disabled
System: Settings: General= NextDNS IPs

Can anyone assist to identify where is the issue and why down speed is low via opnsense

Thanks

try to diable you 2nd 10mmbps line and see you can first get above 500mbps using your 5G line
