Specs: Windows 7
Hi all! I am pretty desperate because i just cant get it to work the following problem and fourm is my last hope :

#1 - In my office i have router wich is sharing WAN and i access it form my home with long range antena, so i dont need to pay ISP twice.

#2 on my home computer with wich i access shared connection i want to share this WAN (with my home router) for my home laptop.

How can i solve this. I have some basic networking knowdledge and i have tried WDS. Is there another way to route this traffic trough?

Thank you for your time!

If you had two routers that support "bridge mode" then you could create a bridged connection between the two (office and home) and the router in your house would in turn be able to provide both wired and wireless.

hey! tnx for quick reply.

@Curt R : i have 2 routers same model (linksys wrt45gl), and they support bridge connection. but is it possible to create connection with wireless link or do i have to configure it first in my office?

I know its stupid question but, if configure it now with my wireless link (form home) i dont want to lose connection with this router like here says :

"You should also have the ability to access the web interface for each router. This access should not be via a wireless link but by an ethernet link"

@wanderer : my antenna is connect just to this network, becuse they see each other. it doesnt have 360 deg range.

media-freak I will try to be clearer with my question

"and i access it form my home with long range antena"

is this connected to a router or your pc?

All router configurations must happen wired first. Once setup you can then access/make changes wirelessly.

my computer is connected to that network trough wireless lan card on wich i have my long range antenna.

now the problem is, if go and make config for bridge connection at home trough wirless link, is there a possibility to lose my link so i will have to go to my office and configure it there by ethernet?

as you see by now i am curious if i can achieve this from home with wireless link where i have access to office router config on wich i am connected to.

is it possible or will i lose the link? i have never done bridge so sorry for my lame questions :)

You will lose the link during setup so yes you will need to go to the office and home to set this up. Sorry no shortcuts.

Might be easier to take the home router to the office to setup wireless bridging between both. then take it home to setup for pc access.

You do understand that if you need a long range directional antenna at home wireless bridging may not work due to distance between the devices?

You probably misunderstood me. My home computer which is connected to my office network and i am getting WAN from, i wana share this WAN with with another router hooked up in my home computer.

i have made this diagram to make it 100% clear on what i am up to : diagram

Home computer will still be connected cause this is my only source for the internet. what i wana do is just share this for my home wireless devices.

I can achive this by bridge, right? or i there another way.
do you know some url with this same topic?

the closest i have found is bridge, but i am little confused now because this is actually extending not forwarding wan traffic right?

I didn't understand clearly how you are setup right now when I first read your original post and replied.

How does the antenna on your home connect to your PC? Is it a wired, or wireless connection?

If wired, you could indeed use ICS (Internet Connection Sharing) to provide internet to your home. You would require two network interfaces and you would enable ICS on the one connected to your antenna. The second would be plugged into your home router.

You'd have to do some adjusting of IP addresses to get it all to work, but I think it could be done.

If your antenna connects to your PC wirelessly then your best bet may be to buy two SOHO antennas (for example take a look at EnGenius equipment) and use that to do a point-to-point wireless shot from work to home. In this case, you would have your antenna's connected to your router at each end.

I've never played with one of those extender type antenna's so I'm not exactly sure how they work.

The second router is useless to you. A simple switch is all you need along with a wired nic card in your home pc [in addition to the wireless antenna pc connection]. Then you engage ICS [internet connection sharing - web search it for the how to] between the two.

You will find anything connected to the switch will have very slow internet access since you are routing it thru the pc and then thru the wireless with its large overhead.

What was being proposed was wireless bridging between the two routers.

i already have that router so will have to do :) tnx for advice.

problem is that everywhere i search for how to configure this, is always a simple method where you just put your internet cable into router and you share wan.

any site suggested for this solution?

You can use the router as a switch by disabling its dhcp server and only making lan connections to it.

I already gave you the only solution you can have given the criteria you have stated. Router to router bridging is off the plate.

You don't have an internet cable in your home so the "simple" simply isn't going to happen.
