GL.iNet GL-MT300N-v2
|
|
********************
|
|
|
|
The GL-MT300N-v2 "Mango" is is very similar to the MT300A, but is
|
|
based on MT7628 instead of MT7620. It's also marginally cheaper
|
|
and comes in a yellow case not a blue one. It's different again
|
|
to the v1, which has only half the RAM.
