Hi Will, I just tested the non-OP24 firmware (same version 4.8.2) and it did NOT improve wifi speed. What else can we try?
Could you send us your current router configuration (a backup exported via Luci) via private message so we can import it locally and check if we can reproduce the issue?
Please note that before exporting, change the password for accessing the Admin Panel to a random one and also share it with us in the private message.
@monologue9484 – we are waiting for you (we fellow Flint 2 users, that is) 
My suggestion for those who'd like to use OP24 is simple: don't waste your time.
This version is clearly not a priority for GL-iNet.
If you want OpenWrt 24, just install the "Vanilla" OpenWrt.
For vanilla OpenWrt, check the installation steps here, and the discussions here.
For a customised version of OpenWrt, check here (@pesa1234 is doing much more progress than GL-iNet)
