I cannot get my wifi on my RPI running Arch Linux to connect to my router.

I have had it connected previously, after a lot of messing around (I still don't know what I did to get it to connect though!!)

So now, when I start the RPI and use

netctl start wlan0

I get an error. Looking at journalctl -xn I can see

Looks like something to do with dhcp lease????????

Does anyone know what I need to do to correct this?


  • alarmpi dhcpcd[1419]: timed out indicates the problem may be external to the Pi. I was unaware Arch used dhcpcd (but I don't normally use Arch). dhcpcd is a new network client which is very robust, and is default in Raspbian for the last year.

  • I now have it connected. Horray!! I used TimeoutDHCP=30 and it works. Now the problem I have is that I cannot ping or SSH. Sounds as if this is a problem with the BT Home Hub 5 perhaps but need to work out what I need to do now.....
