I've been given a static ip to access the internet. I can set the static ip using NetworkManager. The details of my route and ip addr are as follows:

What I have is:

ip: 192.168.1.63/24
gateway: 192.168.1.1
DNS: 8.8.8.8

I set those for a wifi profile in NetworkManager and I am set.

> ip addr
wlp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
 link/ether 08:3e:8e:8e:12:8b brd ff:ff:ff:ff:ff:ff
 inet 192.168.1.63/24 brd 192.168.1.255 scope global noprefixroute wlp3s0
 valid_lft forever preferred_lft forever
 inet6 fe80::4cc3:48dd:8968:b0e4/64 scope link
 valid_lft forever preferred_lft forever
 inet6 fe80::cb08:73fd:d365:a201/64 scope link noprefixroute
 valid_lft forever preferred_lft forever

> ip route
default via 192.168.1.1 dev wlp3s0 proto static metric 600
192.168.1.0/24 dev wlp3s0 proto kernel scope link src 192.168.1.63 metric 600

I've been trying to set the same ip using netctl but it seems like I can't flush the device properly. This is what I do to connect to the internet using netctl.

systemctl stop NetworkManager
wifimenu

I then select the wifi access point which gives me a random ip. I then try to set my static ip like this

ip addr flush dev wlp3s0
ip route flush dev wlp3s0

ip addr add 192.168.1.63/24 broadcast 192.168.1.255 dev wlp3s0
ip route add default via 192.168.1.1 dev wlp3s0 proto static src 192.168.1.63

but now my ip addr and route details are like this:

> ip addr
wlp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
 link/ether 08:3e:8e:8e:12:8b brd ff:ff:ff:ff:ff:ff
 inet 192.168.1.63/24 brd 192.168.1.255 scope global wlp3s0
 valid_lft forever preferred_lft forever
 inet 192.168.1.208/24 brd 192.168.1.255 scope global secondary noprefixroute wlp3s0
 valid_lft forever preferred_lft forever

> ip route
default via 192.168.1.1 dev wlp3s0 proto dhcp src 192.168.1.208 metric 303
192.168.1.0/24 dev wlp3s0 proto dhcp scope link src 192.168.1.208 metric 303

It looks like I can't get rid of the 192.168.1.208 address. Does anyone know what the problem is?

It says proto dhcp in the ip route output. So I'd guess either wifi-menu, or your profile sets up dhcp mode, so .208 address is regenerated after flush.

Your profile should look something along these lines:

/etc/netctl/wireless-wpa
