Why is my router assigning 10.0.1.2 IP Address?

I have a linksys cisco wrt 160nl

I have noticed that all the devices connected lately, about 30-50% of the time the internet will not work. I go to see the /ipconfig, or on the iPhone or iPad settings, and see that the IP address getting assigned is a strange one: 10.0.1.2. I "renew lease" on iphone or /release/renew on pc, and it seems to work (sometimes it takes one or two tries).

Here is what it looks like before:
And after i "renew lease":

Since this happens on each of my connected devices, I'm suspicious it's the router.

The router is set up as a DHCP server that is supposed to assign IP's 192.168.1.5 to 54

I usually have 5-10 devices in the house attached at once.

Any ideas on how to fix?

IMessage not working with only one contact?

I have an iPhone 4, as does my friend. We had been imessaging when all of a sudden it wouldn't send. I double tapped send and set it to send as a text, but now it will not go back to imessage. I can still imessage everyone else, just not him and its driving me crazy! Any help would be appreciated. I've turned airplane mode and imessage on and off, restarted phone, deleted contact and message thread. Nothing works.

IPhone 5 using lots of data?

I have noticed that I'm using almost 4 times the amount of data on my iPhone 5 than I was using on my old 3GS.

The app using most seems to be Safari, it seems to use about 1MB per web page.

Is this normal?
