Slow vlan throughput

Credit to: https://www.ivobeerens.nl/2018/06/04/slow-network-throughput-between-ubiquiti-edgerouter-vlans/

Noticed some issues with slow WAN speeds after moving my clients in to a new VLAN (roughly half duplex).

1. SSH to the edgerouter

2. run

show ubnt offload 

which should show IPv4 vlan = disabled

qhrizz@ER-4:~$ show ubnt offload

IP offload module   : loaded
IPv4
  forwarding: enabled
  vlan      : disabled
  pppoe     : disabled
  gre       : disabled
  bonding   : disabled
IPv6
  forwarding: disabled
  vlan      : disabled
  pppoe     : disabled
  bonding   : disabled

IPSec offload module: loaded

Traffic Analysis    :
  export    : enabled
  dpi       : enabled
    version       : 1.564

3. Enter configure mode by typing configure

4. Enable VLAN offloading with

set system offload ipv4 vlan enable 

5. commit

6. Try out the setting (no rebot required)

7. Save the setting with save
