Ubuntu 7.10/Issues/ipw3945 Wireless Network Module Issues

From DellLinuxWiki

Description: When using the ipw3945 wireless module, the network connection can drop or lockup during heavy transfer rates.
Systems Affected: Inspiron 1420n, 1525n, XPS 1330n
Impact: Wireless connection drops. Data transfer stops.
Workaround: Use network module iwl3945 instead.

Create a file called /etc/modprobe.d/blacklist-ipw3945 and add:

blacklist ipw3945

Add to /etc/modules:

iwl3945

Reboot. After the system restarts, verify that the module iwl3945 (and not ipw3945) is loaded:

$ lsmod | egrep 'Module|iwl|ipw'

You should see an output that looks like:

Module                  Size  Used by
iwl3945                88168  0
iwlwifi_mac80211      175112  1 iwl3945
cfg80211                7304  1 iwlwifi_mac80211

As seen, only the iwl3945 module is loaded.
