Thanks for your answer.
My pings (perhaps all DNS lookups) are slow even if connect my PC to
both the wireless router and the cable, i.e. when there are both
a "fast" (metric 0) and a "slow" (metric 2000) interface.

Fast (i.e. normal ;-) state happens only when net.wlan0 is stopped.
When I start net.wlan0:

Remote internet hosts (f.i., google) and local.
BTW, I can't ping 192.168.2.1, i.e. the wireless router. But I can
under Windows!
