Using network-manager-gnome to bridge eth0 and wlan0 - wnl - 11-05-2015
I installed Linux Lite on my ASUS Eee PC1201-HAB Netbook specifically because it seemed to have a version of network-manager-gnome which allows one to add a WiFi entry to the Bridge slave list. When running Windows XP on this same computer, I am able to "bridge" the Ethernet and WiFi connections so as to allow the machine to bridge two segments in my LAN, namely between this machine and the router downstream of it (or daisy chained to it).
I have been able to set up the Bridge, and have played around with every configuration gadget I could find. Basically, the Bridge never activates. (Actually, at one time I had all three devices showing in the "Connection Information" tabs. But eth0 shows up as the default and seems to be where packets get sent unless it is disabled.)
So my question is very simple: When one has a Bridge configured, how is it made to activate, i.e. what triggers it to go configure the eth0 and wlan0 interfaces, try to connect, and login to the WiFi and begin working?
Thanks for any and all help you can offer.

Hi,
LL is based on Ubuntu 14.04, a quick google show lots of eth/wlan bridging
It involves configuration, and installing bridge-utils
Code:
sudo apt-get install bridge-utilsGoogle: Ubuntu 14.04 bridge-utils
Things like this example
Re: Using network-manager-gnome to bridge eth0 and wlan0 - wnl - 11-05-2015
Yes Wirezfree, I have poured over many things appearing to address the issue on the web. In fact I just finished trying to get it to work by using the parprouted command. But all of that other manual configuration is EXACTLY what I'm trying to avoid by using network-manager and network-manager-gnome. If you think that the bridging in network-manager-gnone isn't able to do what it seems made to do, just let me know and I'll stick with Windows XP in that position.
Also, I'm curious, have YOU ever done this using the bridge-utils?

Hi,
I remember a long time ago on WinXP doing some "bridge" type connection, I think that was for ICS..??
I have never found a need for it for years since connecting device straight to router.
I don't have WinXP anymore, apart from a VM running an image of my last XP PC.

In Windows XP, a bridge is a separate concept from Internet Connection Sharing.
I'm trying to run eth0 (via a Cat5 cable) into a wireless router "modem" port. The wireless router then establishes a network of it's own. The netbook is simply connecting the upstairs DSL-modem/wifi-router to the downstair's router's WAN port. The upstairs unit is configured to know about the router at that node, i.e., so called router behind router.
The whole point of doing this is to get some wired ports (on the downstairs wireless router) for plugging older machines into the network without buying a USB wireless adapter for every machine. But it also offers some degree of isolation of upstairs from downstairs as I rent the space.

Of course all this will depend on Models of Routers... And how much I recall
Couldn't you just connect the 2 routers via the Ethernet cable, segregate the two networks at the routers, Router 2 only having access to internet..??
I had something semi-similar, but I had a Linksys router and a version of dd-wrt along with ISP stuff.. Now that router resides in my camper
... I had a separate network for working on other peoples virus ridden stuff
Some info/ideas

Re: Using network-manager-gnome to bridge eth0 and wlan0 - wnl - 11-05-2015
No, I couldn't do that.
I have some additional data though. I stuck a second NIC in one of the (already) wired machines. Then I tried to setup a bridge (using the network-manager-gnome interface) between the two NICs. I was unsuccessful in getting anything different. The question is, once a bridge entry is setup, how is it activated?
Re: Using network-manager-gnome to bridge eth0 and wlan0 - Wirezfree - 11-05-2015
O.K,
If I understand correctly..??, you want wired ports available downstairs with out running cables..??
I had a similar situation.
I wanted to connect my TV, STB and media player to my network without cables back to my WiFi router ports.
I got a WiFi bridge with 4 ports that connects to my WiFi Router of ebay for about £15, works perfectly.
It is powered from a spare USB socket on the back of my TV, so no need for another power plug/adapter.
At the moment the only one I can find is this one , a new one.
There are one's that do the same, but run over the electrical house wiring,
but they generate interference on short-wave radio.
Re: Using network-manager-gnome to bridge eth0 and wlan0 - wnl - 11-05-2015
Yes this. This is indeed what I want to do ... only without buying anything. I have a perfectly good netbook (broken screen, iffy power switch) which can do this using Windows XP. I want to run Linux Lite in place of Windows XP so that I can rdesktop into it and for other reasons. (By the way, Windows XP Home Edition doesn't support rdesktop'ing in but the Pro edition does. There is a way to fake it, but I'm not going there either.)
My current state of affairs is trying to grok the man page for nmcli which apparently lies beneath network-manager-gnome. I feel I'm making progress and appreciate your kind help.

Can you when hardwired to router have the pc broadcast an SSID? And pick it up say a phone and access internet? Then maybe its something on the router, like a repeater for the wireless?? Wish my other router was here lol...
