Henry,Mark,All Linux gurus.
I bought a new ASUS 15 inch 4 processor note book and the wireless
does not
work under 10.1.
I saved the original sys 7 350 Gig HD and put a 1T HD in for Ubuntu 10.1
The wireless worked under sys7
I don't like the GUI user interface on 11.04 or later.
Too simplistic,
What do I put in all these boxes?

Paul,
I switched to Linux Mint, Mate Edition now and it works for me
as a desktop interface. You can give it a try and see if
you like it.

I have problem with the Cinnamon edition.

Good morning Paul. Enjoy the rotary newsletter - particularly with
engine electronic control info. A little confused on which
microcontroller you are furthest along on, since you have shared info on
a few different microcontrollers these past few months. You and others
have shared so much to further rotary engine for aircraft use - that I
enjoy reading, that I feel I would like to return and share in this
small way.
Don't know the specifics of your laptop, however, this checklist may
help narrow the problem for this and future :
- Most of the time, it is configuration issue.
- Is there a button on the laptop to turn on/off wireless [ my Compaq
laptop has one, obviously check this first ]
- Have you tried logging in as the root user during boot up and then
going to the network screen to make sure you have administrator
privileges to make changes to the operating system ? Log out after
you make any system changes and log back in as your normal user account
that you have set up. Unless you are setup as a superuser with the same
administrator privileges as root, switching to the administrator account
is the sure way.
- Many laptops are setup from the factory to use DHCP to have your new
device's IP address assigned by the network DHCP server,
check to see if your new laptop is set up to use this method of
receiving an IP address.
- Go to the " Terminal " application, basically a window that gives you
command line access. You can type " su " and then enter the
root password to become the administrator for any changes. Type "
ifconfig " and see the display of all interfaces for your laptop, their
MAC addresses as well as their IP addresses. You will note that there
will be a longer, different IP address for IPv6 interfaces. Because the
internet IP addressing system is soon running out of space for numbering
IPv4 addresses, the internet is phasing into the longer IPv6 addressing
space - similar to phone companies issuing new prefix codes ahead of
phone numbers.
Write down the MAC addresses and associated IP addresses for each
interface. It should show you which interfaces are wireless. The
loopback address 127.0.0.1 can be ignored, but can be used to test the
device to see if the hardware works.
My guess is that your new Asus laptop has a different IP address than
what YOUR network is, so it does not know the " gateway " address to
reach your network. So, if you want your new laptop to be on the same
LAN [ local area network ] as your other computers/devices, then the
first 3 octets of a IPv4 address has to be the same and the last octet
has to be unique. Your new laptop can
either by given an IP address by the network DHCP server or you can
manually force your new laptop to an IP address by putting in the
numbers in the network configuration tool, aka Static addressing. You
can always change this right away without a problem. For your local
network, you want to use a NON ROUTABLE address range - one that cannot
be reached by an outside computer on the internet. Your router will
automatically prevent any internet address from reaching any device on
your LAN, unless you allow it to. Here are some of the non routable ranges :
10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
- Go to another computer that has a wireless connection to your network
that you want your new Asus laptop to connect to and while
in the command line [ DOS window if using a Windows operating system
computer, Terminal if using Linux type ] of the working computer, type
in " ipconfig " if a windows operating system computer and " ifconfig "
if a linux type computer. Use the first 3 octets of the IPv4 address
from the working computer to fill in the IP address of your new computer
and give it a unique address for the last octet. Make the MASK address
the same and the GATEWAY address the same to reach the internet or some
other LAN.
- Once the new IP info is saved on your laptop, logout and then log back
in or if easier, reboot. If you still cannot connect, check the
IP address of your new laptop. If it has the same first 3 octets of your
other working computers/devices on your network, then check your router
and see if there is a network filter that is preventing your new device
from accessing the wireless LAN. You can add your new laptop MAC address
in this section to allow the new computer to be connected to the LAN.
- If you still cannot get wireless, but the first three octets are the
same [ i.e. network address is the same ], you can check the connection
at a low level by going to the command line of any computer on your
network and using the " ping " command - kind of like sonar. " ping
xxx.xxx.xxx.xxx " Try pinging a working IP address of another computer
on your network from your new laptop. You should see the replies in real
time with time taken to do a round trip. If it works, it means that your
new laptop can reach other computers at the lowest level. If you try
pinging your new laptop from another working computer on your network,
it will either show you the round trip times or " unreachable ". If
unreachable and the network addresses are the same, I would suspect
either a hardware issue with the wireless section [ unlikely ] or a
software driver needed / update needed [ more probable ].
If your router is the DHCP [ Dynamic Host Configuration Protocol ]
Server, and you would like your new laptop IP address to be managed by
the router / DHCP Server, then you you can add your new laptop by using
it's MAC address and reserve an IP address in the range managed by the
DHCP server and then go back to your new laptop and change the network
address method from manual to DHCP. Static addressing is preferred if
your computer will be acting as a server and you never want the IP
address to change. DHCP addressing is more flexible if your computer /
device is mostly acting as a "client " on the network and especially if
you have a lot of devices hanging on the network - easier to manage in
one spot.
Hope the above checklist helps.
