Hi All,
I ran into a weird issue that I couldn't find any answers on the
Internet. My aim is to setup a wireless hotspot, sharing my existing
internet connection on the same single wireless interface card. The
following shows the step of doing it.
iw phy phy0 interface add wlan1 type __ap
iw phy phy0 interface add wlan2 type station
ifconfig wlan1 hw ether 52:54:00:11:22:33
ifconfig wlan1 192.168.77.1 netmask 255.255.255.0 up
dnsmasq -C dnsmasq.conf # start dnsmasq
hostapd -d hostapd.conf -B # start hostapd
wpa_supplicant -i wlan2 -c wpa_supplicant.conf -B
echo 1 > /proc/sys/net/ipv4/ip_forward
# NAT rules
iptables --table nat --append POSTROUTING --out-interface new0 -j MASQUERADE
When I use a laptop connecting to the network broadcast by the
hotspot, there's no problem with it. I got an IP address assigned and
can ping the access point, here 192.168.77.1. However, I observed
significant amount of packet loss during pinging (I used ping -t
192.168.77.1). I also found that if I create only one virtual
interface on ath9k, it works pretty well (no packet loss from ping).
If I create one more virtual interface, there's about 10% packet loss
and 40% packet loss right after starting wpa_supplicant. Could anyone
have good insight to this issue?
Thanks and Best Regards,
C.C
