-# Configure PPPoE MTU 1500 RFC4638 (Baby Jumbo Frames)
+# How to Set 1500 MTU for TM Unifi PPPoE on OpenWrt
+
+PPPoE normally limits MTU to **1492**.  
+Set it to **1500** to try full-size packets without fragmentation.
+
+Add this to `/etc/config/network`:
+
+```conf
+config device
+    option name 'wan'
+    option mtu '1508'
+
+config device
+    option name 'pppoe-wan'
+    option mtu '1500'
+```
+
+Then restart the network:
+```bash
+/etc/init.d/network restart
+```
+
+✅ PPPoE now runs with full 1500 MTU on TM Unifi.
