NeddySeagoon,

It worked! :D :D :D :D

I turned off net.eth0 so that it wouldn't boot on startup.
Rebooted the Pi.
Typed "dhcped wlan0" on the command line, without the quotes.
Now, the wlan0 interface is up and I can ping to a public ip address.

Next question:
How do I get wlan0 to start up on boot?

Thanks,

Don James

That looks OKish.
Having two interfaces in the same subnet is a bad thing.

The output of route will be interesting.
Save it before you follow the rest of this post.

For testing, edit /etc/rc.conf and set
Code:
rc_depend_strict="NO"

Read the comment and understand what it does.
You will need to uncomment it.

Stop eth0 and I would expect WiFi to work.
Any one at a time should work.

donjames,

You missed a lot of your Gentoo introductory education as you skipped the handbook install on the Pi.

There is a example net file at
Code:
/usr/share/doc/netifrc-<ver>/net.example.bz2

That's a good read.

However, you want to set up your Pi2 as a router, so knowing that all the bits work now, you may want to consult the Home Router guide.

The Pi2 has all the I/O you will be using for a router on a single USB2 port. That gives you 440Mbit/sec for all of your network traffic. Will that be adequate for your traffic?

If you must use a Pi, the Pi3 has SDIO Wifi built in and a single USB2 port for everything else.
The Pi4 is better yet. It has SDIO Wifi built in, a real 1Gbit ethernet port and separate USB3 on a single lane PCIe bus, so its limited to 4Gbit/sec.

Depending on what you want to route and how fast. the Pi2 may be good enough.

NeddySeagoon,

I finally got the wireless to work reliably.

File: /etc/wpa_supplicant/wpa_supplicant.conf:
Code:
network={
  ssid="livingroom"
  psk="abcdeabcde"
  # The higher the priority the sooner we are matched
  priority=5
}
network={
  ssid="etscom"
  psk="abcdeabcde"
  priority=4
}

network={
  ssid="RB411AR"
  psk="abcdeabcde"
  priority=3
}

######## end of file ###########

In the file: /etc/conf.d/wpa_supplicant:
conf.d file for wpa_supplicant

Code:
# uncomment this if wpa_supplicant starts up before your network interface
# is ready and it causes problems
rc_want="dev-settle"

# Please check man 8 wpa_supplicant for more information about the options
# wpa_supplicant accepts.
#
wpa_supplicant_args="-B -M -c /etc/wpa_supplicant/wpa_supplicant.conf"

######### end ##########

In the file: /etc/conf.d/net:
Code:
config_eth0="192.168.1.94/24"
routes_eth0="default via 192.168.1.1"
dns_servers_eth0="192.168.1.1 8.8.8.8"

##### end ###

Thank you very much for all of the help.

Next thing to do is get the router to working. I have made a home router with a pc running Linux, so I am somewhat familiar with the procedure.

I think the Pi2 will be fast enough for me. My internet connection is 100mbits, and I am not running any kind of public server.

Regards,

donjames
