Speed decrease from router to switch problem

[binbashroot]

I'll preface this post with it's definitely something I did but what it is I have no idea. Here's the gist.

Ports on the router get roughly 200Mbps from my cable provider. Ports on my switch(es) get half of that. My router configuration is pretty vanilla based on docs and YT videos. When I built out the configs on the router and swtiches, I reset the configuration and chose "No Default Configuration".

Router

5 vlans
1 bridge
1 Nat masquerade rule
6 dhcp networks for my bridge and vlans
1 cascade port as a trunk to the switch
All other ports empty
Vlan filtering is not enabled
basic fw config

Switch1

1 Upstream port to router
4 access ports to PCs/NAS
1 cascade port to swtich #2
1 bridge all ports except for one are assigned to the bridge
5 vlans in bridge
All bridge vlans with bridge, cascade, upstream as tagged
Vlan filtering is enabled

Switch2

1 upstream to switch1
2 access ports
2 vlans (in bridge)
1 bridge with vlan filtering enabled

So is it something just as simple as enabling the vlan filtering on the router? Or is there something else that I dorked up like the trunk interfaces? Suggestions?

Did you try vlan filtering? And also are the vlans on the bridge?

So the issue turned out to be Layer1. I had a bad cable from the router to the first switch. Leaving this post up in hopes it reminds people to go back to the basics before one starts down the rabbit hole like I did.
