WiPi - failing to make it work

Former Member

I'm new to R Pi.  I have a Wi Pi which I can't persuade to talk to my wireless router.  I don't have an Ethernet cable to connect.

 

I have followed the  Wi Pi installation procedure and modified my /etc/network/interfaces file to correspond to my router's ssid and password.

 

The wipi itself flashes and lights up as if working, whether plugged directly in to the usb port, or plugged in to my powered usb hub.  But during boot there's a series of failed dhcp connections at different 'intervals', 'Unable to lease on first try.  Exiting' and 'Failed to bring up wlan0'.

 

When I try pinging I get 'Network is unreachable'.  There is no inet addr showing on ifconfig

 

Following some stray advice from elsewhere I tried creating my own wpa_supplicant.conf file but that doesn't seem to have helped.

 

I would welcome any suggestions about how to solve this.

 

I notice the encryption on my laptop to this router is 'aes' not 'tkip'.  Does that mean I should modify some entries?

 

Thanks, alan

    Thanks to you Mark and Derek for the tips.  I have followed the route of forcing a fixed IP number, though I've done that from the pi as a static rather than dynamic connection, not from the router.  And the logs helped me to see what I'd been doing, though I never grasped quite how it all looks from the router point of view.

     

    It *is* working, though I'm not absolutely clear what it was that made it work image  I confess I thought the dongle would work out of the box and the hard part would come later, I never thought it'd take me a week just to get a network going in the house!  Still here I am, now able to direct affairs from puTTy inside my laptop, so who knows what heights I might soar to next!

     

    Thanks again.  I'm having a go at blogging my progress, you guys get (anonymous) thanks : http://ohwhypi.blogspot.co.uk/

    Good to hear its going.

    I tend to have fixed IP's so I know what is suddenly going to a site, and why does it need to go there ...usually its updates, but here has been the odd strange one.

     

    I'm now curious.

    Is it a WiPi (available through E14) or some other USB WiFi that you have.?

     

    WiPi has the drivers inbuilt to wheezy/raspbian while the others may need you to download them.

     

     

    You should be able to tag our answers as helpful or answered, which also tags it as answered and helps others who have similar problems.

     

     

    Cheers

    My Wi-Pi dongle works perfect when i use it with dhcp,

    iface wlan0 inet dhcp

     

    but when i try to use with static ip it is not working n even wlan is not up. what could be the issue.

    i used as :

    iface wlan0 inet manual

    address

    netmask

    gateway

    wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf ( I READ SOMEWHERE IN ANY FORUM)

     

    i have created my own wpa_supplicant.conf

     

    where is error? i am new to raspberry pi and seting Wi-Pi dongle, i have used some others but not Wi-Pi

     

     

    Regards
