How to setup laptop as ethernet repeater?

HenryJia · 2014-02-19 20:22:28

Hi guys,

Well I've got a desktop but I have no ethernet in my room. Is there anyway to setup my spare laptop as a ethernet repeater so that it the data recieved on wifi is bridged t o the ether net and to my desktop. If you didn't quite get that because of my working I made a diagram below.

WiFi ethernet
Router-------------->Laptop----------------->Desktop

A Arch Wiki page link about how to do this would be helpful

Take a look at wiki page and forum post (I'll add this to wiki soon).

Stealing wifi, are we ??

You are probably trying to set up an acces point, not a repeater.

Inxisible, I am not stealing wifi, I have wifi, just not in my room, router is too far a way from my desktop

I looked on the arch wiki page Saran posted and the command

sysctl net.ipv4.ip_forward=1

doesn't work

IT gives me the error cannot stat /proc/sys/ip_forward no such file or directory

You will need this package https://aur.archlinux.org/packages/create_ap more info here https://bbs.archlinux.org/viewtopic.php?id=162895 and here https://wiki.archlinux.org/index.php/So … cess_point

Actually the example shows you how to do the opposite i.e. ethernet --> wifi, but nothing prevents to do the reverse.

No, I don't think so.

You missed his humor tags -- especially the one where he was sticking out his tounge

This seems odd. It shouldn't be trying to modify /proc/sys/ip_forward (as that doesn't exist). Rather it should be trying to change the value in /proc/sys/net/ipv4/ip_forward...

sysctl has some really nice tab completion. Have you tried using that? It's completion (at least on zsh) uses the format with /'s instead of .'s, so don't be alarmed by that as either is correct.

Edit: As a test, you could always just do:

# echo 1 > /proc/sys/net/ipv4/ip_forward

This achieves the same thing without the use of sysctl.
