Re: [Wing] How to use multi-radios

Hi,

We run wing on three desktops.

The following is our deployment (case1):
A. With 1 NIC on channel 1, and is able to connect to Internet.
B. With 2 NICs on channel 1 and 6, respectively.
C. With 1 NIC on channel 6.

Links between PC A and B are work correctly,
all node information in lt.hosts, lt.links and lt.routes are found.

But the links between PC B and C are strange,
lt.hosts, lt.links are exist(both forward and backward are exist),
and metric on each link seems normal(around 1000~2000),
but we can not find any information about lt.routes.

Is there anything I may lost?

--------------------------------------------------------------------------------------------

After experiment describe above, we try another scenrio.

The following is our deployment (case2):
A. With 1 NIC on channel 1, and is able to connect to Internet.
B. With 2 NICs on channel 1 and 6, respectively.
C. With "2 NICs" on channel "11 and 6", respectively.

In this case it work correctly,
we can use ping to access outside Internet (8.8.8.8).


Then we change the deployment again.

The following is our deployment (case3):
A. With 1 NIC on channel 1, and is able to connect to Internet.
B. With 2 NICs on channel 1 and 6, respectively.
C. With 2 NICs on channel "6 and 11", respectively.

PC A and B are the same in case2.
On PC C we just switch two NICs' working channel.
then it isn't work again same as case1.


We guess:

If we want to use multi-channel, PC C's first NIC channel must match PC B's first NIC channel.
Even PC C's first NIC channel match PC B's "second" NIC channel, there is no connection between C and B.


Thank you.
