Ubuntu Dapper Drake y problemas de impresión

filed in Ubuntu on Apr.28, 2006

Desde hace algunas semanas que no puedo imprimir a través de la red. Es una PC con Linux, Ubuntu Dapper Drake 6.06 (que todavía está en Beta), y cuando la máquina tenía instalado la versión anterior (Breezy Badger) la impresión funcionaba sin problemas. La impresora está conectada a una PC con WindowsXP.
El problema, que está documentado en Launchpad, se puede solucionar descargando la versión 3.0.22 de los paquetes de samba de http://www.linux2go.dk//ubuntu/pool/main/s/samba/

Para instalarlo los paquetes,

$ sudo dpkg -i \ samba-common_3.0.22-1ubuntu1linux2go1_i386.deb \ samba_3.0.22-1ubuntu1linux2go1_i386.deb \ smbfs_3.0.22-1ubuntu1linux2go1_i386.deb \ smbclient_3.0.22-1ubuntu1linux2go1_i386.deb

La impresión funciona ahora perfectamente. Cuando salgan paquetes nuevos en los repositorios de Ubuntu, reemplazaran automáticamente a éstos.

The mistery of the DWL-G700AP dropping connection (solved)

Update: en castellano: ver al final del post

Last december I bought a Wireless Access Point for my home network. This Access Point is a D-Link DWL-G700AP, and offers an 802.11g connection and WPA2 encryption. The problem was that I could not get a reliable connection for more than 10 minutes (sometimes I could work as long as an hour without a glitch, but then the connection dropped misteriously…).
The problem was not the location of the AP nor the distance to my laptop (they are in the same room). I tried several things: updated to the latest firmware, disabled encryption on the AP, changed transmission channels, “short preamble”, played with the signal strength, limited the AP bandwith… no results. Googling around it seems that connection-dropping is standard behaviour for this AP.
Last week I had to copy large amounts of data between two machines on the network (no wifi between this two machines). The transfer speed between the machines was unbearable, so I decided to upgrade the 10Mbps network hub to a 10/100Mbps switch. Wonderfull side-effect: after that, the D-Link AP has never dropped signal again. Should have thought about this before…
Conclusion: if you have an DWL-G700AP, connect it to a 100Mbps hub or switch. Expect connection dropping and lots of frustration otherwise.

En castellano y resumido: si tienes un Access Point WiFi D-Link DWL-G700AP, y has estado a punto de tirarlo por la ventana porque la conexión wifi se cae continuamente, sin importar lo que hagas, antes de destruirlo prueba una vez más, conectándolo a un hub/switch de 100Mbps.
