[SOLVED] No DHCP on wireless / clearfog pro

Installing and Using OpenWrt Network and Wireless Configuration
1

Hi, i just upgraded from v17 to v18. Unfortunately, the config was pretty incompatible. As soon as i tried to backup the config from v17, the system was not responsible anymore (dont know what exactly happened...), so i started again from scratch with some help of the old backup.

Everything seems to work, expect my wifi. And i really do not understand why.

if someone has a clue what could go wrong or has improvements, this would be very appreciated!

It seems like my phone would connect but then it says "Retrieving ip address" and then it aborts after a couple of minutes.

Did you change the configuration manually or through Luci?

I don't really know what the problem is, but I suggest trying to hard code the wifi channel. If you configured it manually you could try resetting it to default settings and use Luci to change only what's needed for wifi to start. If you can connect to the wifi after that then change one thing at a time.

I changed it manually and through luci

What do you mean with hard code the channel?

very strange, i just updated the wifi config, now its working again... wtf

Under your config wifi-device 'xxxx' add:

option channel 'x'
