Hi all,
I am trying to get my wireless operating on my laptop at home. I know that the wireless works fine, as our sysadmin got it functioning at work.
So I plug in our new wireless broadband router into the (ntl) cable modem, and set up the firmware: DHCP on, security off (for the time being).
As root I run:
sbin/modprobe rt2400
/sbin/ifconfig ra0 up
/sbin/iwconfig ra0 essid lemonpie
/sbin/dhclient ra0

Here's the output of ifconfig:

To my (limited) understanding, it appears that the wireless interface is operational, and an IP number issued ok.
When I run kwifimanager, I see the correct network name, IP number as above, noted that encryption is off, registers a strong signal. When I look at the connection statistics, I see it change regularly with time, suggesting a real connection between laptop and router.
Here's the output of netstat:
[root@localhost nick]# netstat -rn

And I can connect fine to the internet via the ethernet cable (connected to the modem via the wireless router).
BUT.
When I disconnect the ethernet cable, I no longer have access to the internet. Can't ping anything, no browser connection, no ssh.
I've tried to search the existing answers on LQ (and google etc etc) but I can't find anything more to do at this stage. Please forgive the ignorance which clearly is preventing me from seeing the obvious!
Would appreciate any and all help.
