Not recommended for future use with OpenWrt due to low flash/ram.
Limitations in extensibility and stability of operation are to be expected.
See 432_warning for details.

The ZBT WR8305RT is a 802.11bgn wireless router based on the MediaTek MT7620N SoC. It has five Ethernet ports, out of which one is the wan port. It has one radio (SoC-based 2.4 GHz 802.11bgn). It comes pre-installed with OpenWrt Chaos Calmer.
