Hardware Version: V1
Firmware Version: all

Hello,

 

1. - there is an annoying bug present in all fw versions:

- cant add entry to Address Reservation, if its not in the address pool.

This working fine other models (and other brand too)

 

 

 

2. - And missing "Always on" option at the PPPoE settings.

Hi,

 

Regarding your point 1.

 

You are right in that this used to be possible on older TP-Link routers and many users, including myself, would have liked this to be kept that way.

 

However, big players in the IT industry apparently have decided that a reservation of an IP address from outside the DHCP address pool is not appropriate, and now smaller players are following suit.

This can be reproduced in the emulators too: using the default pool: IP Address Pool: 192.168.137.100 - 192.168.137.199 and try add any address outside of this, like 192.168.137.75

Hello,

 

well, yes and no. Not all fallow this "nonsense"... 
I understand this too, but not agree with it.
I can accept this, IF its fully implemented; we get an option to define an exclusion range, and working as it has written in the last paragraph: 
" If you do not want to distribute addresses from the whole subnet, you can also define an exclusion range. A reservation that falls into an exclusion range will still work."
