Android phone has Wi-Fi troubles after subnet change I just moved our network access point to a different subnet (which has a different default gateway).  After the change, all the laptop computers adjusted without much issue (some XP computers needed the "repair" option run on the connection).  However, none of the Android phones have Internet access anymore.  They can connect to the wireless access point without a problem, but they can't access the Internet.  This only seems to happen on the Android phones.  I am wondering if maybe it remembers the old settings and isn't picking up the new default gateway?  What can I do to fix this?
Turns out it was a problem with the DNS servers my DHCP was serving up.  The first two were local DNS servers.  I don't know why they weren't working for android (they worked fine for the laptop computers), but as soon as I replaced the second local DNS server with a remote DNS server, things started working.  It also appears that android only pays attention to the first two servers given by DHCP since I had other servers listed after my local server.

It seems kind of fishy that only the android phones had problems with the local DNS server.  I wouldn't mind finding out what the underlying problem is, but changing the DNS servers is an acceptable workaround.
