Internet connection via ethernet in Windows

General Topics
1

I just got rid of my USB modem and bought a cheap wireless ADSL router, mostly because trying to connect through a USB ADSL modem is a pain in Ubuntu.

Ubuntu connects to the internet via wired ethernet and the wireless network without a hitch.

However in Windows, the ethernet connection appears in the notification area but nothing will connect. The Intel wireless utility recognises the network but won’t connect.

Does anybody have a link to a good tutorial on how to connect to the internet via an ethernet connection?

I have ZA in Windows. Should it recognise a new connection and allow it or will have I to uninstall/reinstall it? (Tried closing ZA but still no connection wired or wireless.)

Any good links for sorting out wireless connections?

Many thanks in advance.

Ethernet configuration on ‘auto’ (for IP, DNS, etc.) should be enough on Windows if the wireless is detected and allowed to run.
On Linux, no problem, everything will be configurated as ‘auto’.
I think the firewall should detect the new network, if not, you can uninstall/install the firewall again.
I have both, wired and wireless, both Windows and Kubuntu. No problems.

Hi FwF,

from command line type:

$sudo pppoeconf eth0

There is some online information to be found here: https://help.ubuntu.com/community/WifiDocs/WirelessTroubleShootingGuide
Just add this iptables code to make it all a little more secure after you set it up…

ROUTE - iptables ROUTE target 
  route add -net 127.0.0.0
  route add -net 224.0.0.0 netmask 240.0.0.0 dev eth0 deny
  # To force all outgoing icmp packet to go through the eth1 interface 
  # (final target) : route add -net 192.56.76.0 netmask 255.255.255.0 dev eth0
  iptables -A POSTROUTING -t mangle -p icmp -j ROUTE --oif eth1
 
  # To tunnel outgoing http packets and continue traversing the rules :
  iptables -A POSTROUTING -t mangle -p tcp --dport 80 -j ROUTE --oif tunl1 --continue
 
  # To forward all ssh packets to gateway w.x.y.z, and continue traversing
  # the rules :
  iptables -A POSTROUTING -t mangle -p tcp --dport 22 -j ROUTE --gw w.x.y.z --continue
 
  # To change the incoming network interface from eth0 to eth1 for all icmp
  # packets (final target) :
  iptables -A PREROUTING -t mangle -p icmp -i eth0 -j ROUTE --iif eth1

  # To copy (duplicate) all traffic from and to a local ECHO server
  # to a second box (nonfinal target)
  iptables -A PREROUTING -t mangle -p tcp --dport 7 -j ROUTE --gw 1.2.3.4 --tee
  iptables -A POSTROUTING -t mangle -p tcp --sport 7 -j ROUTE --gw 1.2.3.4 --tee
  iptables -A INPUT -p tcp -m tcp --dport 80 -j TARPIT

The wireless connection went through- just had the key entered wrong.

No problem from ZA.

Wired connection still not working even though it’s supposed to be automatic:

Start your computer and log on to Windows. Windows automatically detects that you are connected to the Internet.

Tell that to my computer! >:(

Hi FwF,

As I told in the PM:2. “You can simply unplug the ethernet cable from the back of your computer. This method might be easier than disabling and re-enabling your wired card.”

Does it work if you disable ZA?
Does ZA recognize the network after booting?

7

I tried disabling ZA.

ZA has both the wired and wireless connections in Zones: wireless is working fine now.

I unplugged the cable: Windows told me it was unplugged. I plugged it back in again: Windows told me it was connected. Still no internet connection via the wired connection. ???

OK, I figured it out. I’d used that network connection to connect to my old computer. I had to go to Local Area Connection Properties>Internet Protocol (TCP/IP) Properties>General and select ‘Obtain an IP address automatically’.

::slight_smile:

My new wireless router doesn’t have an on/off switch. Are these things designed to be left on all the time?

Hi FwF,

Good you figured it out, and got it into the air, and yes it has to stay up as long as possible.

Yes, Frank, this is what we’re talking about ‘automatic’ mode since from the beginning.
Glad you’ve succeed 8)

About wireless, don’t you have an icon from the manufacturer that allows to enable/disable it?

My wireless router doesn’t have an on/off switch either. Since it doesn’t have shut off, I take it was meant to be left on.

I had a DSL modem with on/off switch that I did turn off when not online, it went bad & Verizon sent me a new one in exchange for the bad one, no charge. I left the new modem on all the time & it never failed.

I’m on cable internet now. I leave both modem & router on, no on/off switch on either.

Frank,
My wireless router also doesn’t have an on/off switch but, I use NetworkMagic
to secure my connection which is on constantly. :slight_smile:

Can’t you turn wireless off in the routers configuration settings?

Cheers Polonus!

Ah, OK, I see what you meant now, thanks.

I didn’t install the manufacturer’s sofware: the connection works fine with just the Intel wireless utility.

Thanks. I think you’re right that they’re meant to be left on: pulling out the DC plug and putting it back in every day would wear it out quickly, and pulling the AC adapter from the socket and putting it back in will cause voltage spikes.

I’ve set up WPA security. I hope that’ll keep the freeloaders out. (A friend of ours just bought a wireless receiver:

http://www.maplin.co.uk/module.aspx?ModuleNo=49125&doy=6m11

He reckons he can point it in any direction and find an unsecured wireless network- that’s in the inner city, where housing is pretty dense- and saves £15 a month on internet bills. ::))

I couldn’t see any way of doing that. If the router can stay on 24/7, I’ll just move it downstairs and get rid of the cable dangling from the ceiling and connect wirelessly. Now I just have to wait 6 months till it’s warm enough to sit in the garden again and I’ll be ready for some al fresco surfing! 8)

Thanks all for comments!

Frank, there are command line options to disable the network and to re-enable it again.
