Can't Ping gateway or out of network

I'm sure I'm breaking a fundamental rule. Just can't understand what the problem is.
I made a router on a stick scenario with a switch and a router.
The router has f0/0.1 subinterface with dot1Q 1 native
with ip add 192.168.1.1 255.255.255.0

dhcp pool VLAN1
network 192.168.1.0 255.255.255.0
default-router 192.168.1.1

The switch f0/2 to the router is in trunk mode
sw trunk allowed vlan 1-99,150 (for a voip phone)
sw trunk native vlan 80

And the the switches f0/5 is in access mode
The computer has an ip addr of 192.168.1.101
but I can't get the computer to pull a dhcp address.... WHY?

On the switch I go into f0/5 and enter sw access vlan 1
but it won't take that into the config
It has to do with me trying to use the VLAN 1 right?
it's not allowed or what?

Besides the missing IP Helper on the SVI, you should make sure there is no native vlan mismatching going on here.

Make sure your access ports are VLAN'd and up.
Make sure your trunk ports are good, do show int x/x switchport, check
Make sure your allowed and native vlan's are consistent from switch to router
Make sure your host will work if you statically assign it the correct IP, subnet and DG.
Make sure your DG is configured.

Paste your configs and show logging if any of that is still making you scratch your head.

If you have already assigned the PC a static IP it won't attempt to get one using DHCP.

You're trunk has a native vlan of 80 and your router has a native vlan of 1 - you have a native vlan mismatch.

The switch's native vlan is still 1 so doing switchport access vlan 1 is not going to help.

.. and i second that you've already assigned an IP anyway

Thanks guys, I get it that the end devices won't pull addresses while with a static ip, it was just temporary.
The ip helpers did the trick. I forgot a few things. Lol Here is the URL of what I was following so you can see the big picture. Its simple. Just to refresh on VLANS: youtube.com/watch?v=2VboOLyRxyg
It's a Danscourses lecture. And below are the configs. Feel free to critique me on anything. I like that he left the top two computers on VLAN 1 to see how devices not on a VLAN can get accross to other networks as well... I left out passwords for ease. I cringe thinking of doing an past lab of mine. My teacher was such a drill sargent. Lol
