My tablet couldn't connect on ANY wifi network unless I entered the IP manually (I have checked on my router an my phone using it as a wifi hotspot). DHCP just didn't work and the tablet was stuck at "obtaining IP adress". The odd thing is that even the bars that show the network strength went from 5 full bars to 1 bar.
It was odd since wifi was on and it worked fine until I charged my tablet. I didn't do anything in between and reset didn't help. What worked in the end was deleting the dhcpd-wlan0.lease under /data/misc/dhcp.
Could anyone point me to the problem or an error that caused this because I'm a little afraid that it wasn't just a one time thing and that it could happen again.
Edit: Oh yeah I almost forgot. My router was acting up (my PC that is connected via cable was losing internet connection). Could it be that it was the router that messed up dhcpd-wlan0.lease and broke my Iconia?
