How to change AP's channel or TxPower?

[tori22]

Hi, after reading examples, I found there are almost all codes about how to create a new topology.

My question is how to set some important params after topology is created?

For example:

Case1(done):

I want to re-associate ap and sta after sta moves to another ap's neighborhood. cls.update(sta, ap, wlan) It works after I figure out some resource code.

Case 2(still confused):

I want to change one ap's channel and power when I think current channel or TxPower is not good. but after searching source code in link.py, I can't still find a good way.

Conclusion:

1. how to solve case2?
2. Can we add some dynamic params change examples?

Hi,

Please consider https://mininet-wifi.github.io/part3/ for cases #1 and #2. By now It works only with the branch dev.

Thanks for the link. I solved how to change TxPower ; but it doesn't work when trying to change channel according to the code.

py ap1.setChannel(2, intf='ap1-wlan1')

but error shows unbound method setChannel() must be called with IntfWireless instance as first argument (got OVSAP instance instead)

Hi,

Please make sure you have the new compiled version (sudo make install may work).

I just ran sudo mn --wifi and then py ap1.setChannel(2, intf='ap1-wlan1') and it worked.

Thanks for your reply.

I switch to dev branch and sudo make install. git checkout dev sudo make install

It works now. Thanks again.
