Description of problem: I'm using a USB dongle as a wireless access point via hostapd: Bus 001 Device 004: ID 050d:705a Belkin Components F5D7050 Wireless G Adapter v3000 [Ralink RT2573] Bug 716988 was just closed because my USB dongle started working 1st time every time. Unfortunately, that was short lived. I've just tried booting all three kernels on my machine, and kernel-3.3.2-6.fc16.x86_64 and kernel-3.3.4-3.fc16.x86_64 both fail to work. The oldest kernel kernel-3.3.2-1.fc16.x86_64 works perfectly. The failure mode is completely different now though. Everything appears to work fine. I get connected, I even get assigned an IP by my DHCP server, all NAT iptables rules seem to be setup correctly, etc. Unfortunately, no traffic makes it through the interface. I can't even talk directly to my desktop which is the gateway, much less talk to anything in the outside world. Version-Release number of selected component (if applicable): kernel-3.3.2-6.fc16.x86_64 and kernel-3.3.4-3.fc16.x86_64 How reproducible: Seems 100%, it apparently connects successfully, yet fails to talk every time I try on the newer kernels. Steps to Reproduce: 1. see above Actual results: No traffic via wlan0 Expected results: Talking to the internet normally. Additional info: I'm not using NetworkManager, I starting things up "by hand". Here's the script that starts the access point running once I plug in the USB dongle: #!/bin/sh # # Run as root - brings up the access point # ifconfig wlan0 netmask 255.255.255.0 192.168.9.1 sleep 1 service iptables start sleep 1 service hostapd start sleep 1 systemctl start dhcpd.service Here's the /etc/sysconfig/iptables used to do the NATting: # Generated by iptables-save v1.4.9 on Fri May 20 09:58:26 2011 *nat :PREROUTING ACCEPT [34:2176] :OUTPUT ACCEPT [55:4168] :POSTROUTING ACCEPT [55:4168] -A POSTROUTING -o em1 -j MASQUERADE COMMIT # Completed on Fri May 20 09:58:26 2011 # Generated by iptables-save v1.4.9 on Fri May 20 09:58:26 2011 *filter :INPUT ACCEPT [392008:153506294] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [364620:51248845] COMMIT # Completed on Fri May 20 09:58:26 2011 And here's the hostapd.conf file with password and ssid hidden: ctrl_interface=/var/run/hostapd ctrl_interface_group=root macaddr_acl=0 auth_algs=1 ignore_broadcast_ssid=1 wpa=2 wpa_key_mgmt=WPA-PSK wpa_pairwise=TKIP rsn_pairwise=CCMP wpa_passphrase=********** driver=nl80211 interface=wlan0 hw_mode=g channel=11 ssid=*******
Created attachment 583246 [details] dmesg from working 3.3.2-1 kernel
Created attachment 583253 [details] dmesg from failing kernel 3.3.4-3 I said above that I always connected, but couldn't ever actually talk, but now that I've rebooted back into the latest kernel 3.3.4-3, I can't get connected at all. This is the dmesg following that connect attempt.
I just got kernel-3.3.5-2.fc16.x86_64 this morning and tried my USB dongle again, and it appears to be working once more. I connected on my first attempt, and it can ping outside sites, and access outside web sites. So maybe whatever broke has now been fixed.
Thanks for letting us know. If you have issues again, please reopen.
