I have a TV box provided by ISP (also TV channels provider), which has Android 4.4.4 Linux kernel 3.10.23. (I have root already)
It uses PPPoE to get a network so can receive TV stream, but this network has no Internet. It also has wifi, which only works when PPPoE is down.
I want to make PPPoE and wifi work simultaneously, so get both TV stream and Internet. I did some test and find out there must be some process preventing wifi when PPPoE is on.
I use Linux laptop to setup an AP. I make box connect to AP on box's setting layout, when PPPoE on. I see this on Linux:
ap0: STA 74:97:81:xx:xx:xx IEEE 802.11: authenticated ap0: STA 74:97:81:xx:xx:xx IEEE 802.11: associated (aid 1) ap0: AP-STA-CONNECTED 74:97:81:xx:xx:xx ap0: STA 74:97:81:xx:xx:xx RADIUS: starting accounting session E67960Dxxxxx dnsmasq-dhcp: DHCPDISCOVER(ap0) 74:97:81:xx:xx:xx dnsmasq-dhcp: DHCPOFFER(ap0) 192.168.7.125 74:97:81:xx:xx:xx dnsmasq-dhcp: DHCPREQUEST(ap0) 192.168.7.125 74:97:81:xx:xx:xx dnsmasq-dhcp: DHCPACK(ap0) 192.168.7.125 74:97:81:xx:xx:xx FF1004xxxxxx ap0: AP-STA-DISCONNECTED 74:97:81:xx:xx:xx
Connection sucessfully established, and even box has got IP from DHCP (I also see IP on TV for a very short time). Then soon disconnected.
If I unplug the cable, or turn Ethernet off in box's settings, or set a wrong PPPoE password, the wifi works.
How do I find out which process it preventing wifi?
