Sony Ericcson Arc S CayanogenMod dhcp problem


I flashed my phone with the latest CM 9.1.
After some time my phone did not get any IP-Address via dhcp.
Static IP’s were working. So it should be the dhcp-client I thought.
Googled for the problem:

* switch off WiFi
android:/ $ su
android:/ $ rm data/misc/dhcp/*
* switch on WiFi

WiFi is working again :-)

Have fun!
