AttributeError: 'TCIntf' object has no attribute 'configWLink'

Hello, I can't resolve my error while running that simple python script:

#!/usr/bin/python

from mininet.node import RemoteController
from mininet.log import setLogLevel
from mn_wifi.net import Mininet_wifi
from mn_wifi.node import OVSKernelAP
from mn_wifi.cli import CLI

def myNetwork():

    net = Mininet_wifi(topo=None, build=False, ipBase='10.0.0.0/8')

    c0 = net.addController(name='c0', controller=RemoteController, ip='127.0.0.1', protocol='tcp', port=6633)
    ap1 = net.addAccessPoint('ap1', cls=OVSKernelAP, ssid='ssid1', mode='n', channel='1', position='250.0,400.0,0', range=200)
    ap2 = net.addAccessPoint('ap2', cls=OVSKernelAP, ssid='ssid1', mode='n', channel='1', position='250.0,400.0,0', range=200)

    net.configureWifiNodes()

    net.addLink(ap1, ap2, bw=10)

    net.build()

    net.controllers[0].start()

    net.get('ap1').start([c0])
    net.get('ap2').start([c0])

    CLI(net)
    net.stop()

if __name__ == '__main__':
    setLogLevel( 'info' )
    myNetwork()

I assume that I can set bw in addLink method (without that bw declaration everything runs fine, no error occure). If not, why? I have no other idea what is the reason of my error as I run that script on a fresh VM got from your github.

My additional question is whether mininet-wifi requires physical wireless network adapter? (I have only Ethernet physical adapter in that machine)

I will be really grateful for your answer!

Please do a git pull and then run sudo make install

The hwsim module is the only requirement for simulating wifi.

All works fine now, thank you very much!
