Wireless router: works wired, fails wireless


Hello All,

I have a wireless router which connects to the ISP via a cable modem. The wireless router logs in fine (the cable modem is connected via the WAN ethner port). It has 4 ethernet ports through which everything works as expected. Connecting wireless is also no problem, ip is assigned but no communication with the outside is possible:

192.168.1.1 is the router
DNS for the wireless connection is set to an opendns server

Code:
ping google.com
ping: unknown host google.com

ping 192.168.1.1
PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.
ping: sendmsg: Operation not permitted


wlan0     Link encap:Ethernet  HWaddr 00:1d:e0:b5:c9:49  
          inet addr:192.168.1.101  Bcast:192.168.1.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:576  Metric:1
          RX packets:41 errors:0 dropped:0 overruns:0 frame:0
          TX packets:29 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:7136 (7.1 KB)  TX bytes:6080 (6.0 KB)
thanks all

stopping firestarter does it. Why would it block wifi traffic? Works with other wireless networks.
Not sure about the gateway (DHCP is on, both wired and wireless).

Didn't expect it to be a f/w problem either as the wifi doesn't work on a ubuntu and win install. Will look at the win laptop in a moment.

Thanks for your help.

Did a route while connected wirelessly and wired. The results are identical.
Code:
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.1.0     *               255.255.255.0   U     0      0        0 eth0
default         192.168.1.1     0.0.0.0         UG    0      0        0 eth0
Code:
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.1.0     *               255.255.255.0   U     2      0        0 wlan0
default         192.168.1.1     0.0.0.0         UG    0      0        0 wlan0
switching off the windows firewall on the windows laptop resolves the issue too but obviously this is no long term solution.. Any ideas what could be causing it?

Thanks, that solved it. Peculiarly I do not have to alter the interface when connecting to other wireless networks? What would explain this?

Now to find the same setting in windows...

because the interface stays the same
wireless => wlan0
wired => eth0

I think you might have misunderstood the question due to me phrasing it inadequately..

I have connected to wireless networks before without needing to change the interface to the wireless connection interface. This occured for the first time when connecting to the wireless network in question and the same applies to windows installations. So I'm guessing there is something peculiar about this network which makes it behave differently from others..

Thank you for your help, it is working now

wireless, ethernet, and verizon router 'mi424wr'

i have the same isp and router.
i also have the same problems.

i am supplying a link to the brouchure ecerpt below,
because it tells me that i can ONLY use Westell, and D-Link wlan cards
to "talk to" and be "talked to from" the router.

this just kicks me because i have an option to get a laptop to run linux on and the internal wlan won't work with verizon's MI424WR wireless router.

i wasted the time of some of these knowlegdable people with this problem
using a dell optiplex gx810(very old) with a linksys wmp11 wlan pci card.
i did check this verizon router with a d-link pci wlan card and it worked.

link to verizon brouchure excerpt.
