[Commotion-discuss] mesh and gateway (internet) conflict

[Andy Gunn]

Hi Mikhail - my first instinct is to change "This device should always
PROVIDE DHCP" to "This device should always RECEIVE DHCP".

The reason for this is the router or modem connected to the Internet
(not the Commotion device) should be giving out an IP address via DHCP
to Commotion nodes on the Ethernet port. When the Commotion node
receives that IP, it will set itself up as a gateway.

I'm realizing the language is a bit unclear - it sounds like if you
change that to always receive, people connecting to the APs won't
receive IP addresses, but that menu only effects how the WAN Ethernet
ports behave.

I would also recommend plugging the TP-Link with the 3G card into the
switch directly, so the Commotion nodes and APs are all getting DHCP
directly from that, instead of chaining the connection through the
Commotion TP-Link.

Let me know if this resolves things!
-Andy

The "Common Configuration" page is old, and should have been removed.
The "Common Hardware Setups" has replaced it. Not sure how that
happened, it should have been removed a long time ago!

I will fix that in the website.
