Solved how to access a public wifi from a router

December 27, 2012 at 21:25:21
Specs: Windows XP
I have a a Asus RT-N12 B1 wireless router
and 4 laptops.
All laptops (Win XP pro) are wireless capable and can receive the Public WiFi induvidually.
How do I create a completely wireless network, using the ASUS?

The problem I am having with the router(set to "repeater" is that when It finds the network, and I click"connect" it makes me wait for 120 seconds.
Than it tells me that "successfully updated IP settings to 172.31.134.28".
This shows up as”
http://172.31.134.28/ure_success.ht...

ANd then I get no connection ->Nothing
I tried IE8 and Chrome rebooted the Asus a few times--> The same result.. No connection

The IP you listed in your posts above that show up on the router once it connects are public. I would expect if it's a free wifi setup for the IP's it's dishing out to be a private class (in this case, 172.16.0.0/24 instead of 172.31.134.28).

Connect with a laptop and then open a command prompt window (ie: Start >> Run >> type cmd and hit Enter) and perform the following command:

ipconfig /all

I suspect you'll see the laptops IP is either in the subnet I listed above, or within the 192.168.0.0/24 network. If it is, then you know whatever info your router is getting is incorrect and that's why it wasn't working.

Using the extender idea will allow the extender to connect like just another client (like your laptop). With it in turn connected to your router you can then use your router to serve up wireless on your boat.

You should check and see if you don't have a wireless ISP in your area. If you do, it would make more sense, and provide a better service to you, if you went with them for your internet.

I have to wonder, if all 4 laptops do connect to the public wifi without you adding a router into the mix, why do you feel it necessary to have a router in there too? You're just adding complexity and as you can see, making it harder to make things work properly.

There are two rules in computing that smart people adhere to and they are:
1) If it ain't broke, don't fix it
and
2) KISS (you can google that acronym)
You're violating both rules in one fell swoop.

To be honest, what you're doing makes no sense at all and I'm very curious what your reasoning is for attempting to do this. So please explain it to me, I'm very curious.

Curt R, thanks for your answer.

1)The router 'decreases", so to speak, the range or distance. when set to repeater.
highr transmission power than a laptop
2)The laptops can 'hear' the wireless network (2 bars), BUT the network can not always 'hear' the laptops, because of trees and yacht masts swaying in the wind etc.
3)I want to do this on a steel yacht.
In order to receive the signal on a laptop, I have to put it outside on deck, while the router can 'view' the wifi network AP through a polycarbonate window.
The router reception (behind a window)signal is 6 bars
As you can see, there is a reason for this madness.
What's your solution? Thanks

I would suggest you look into a wireless extender. Usually they are just an antenna that you could in turn plug into your router. With a bit of research, you should be able to find one that will have a more powerful radio than you'll get in a SOHO router.

You would deploy this somewhere on top of your yacht where it would have an unimpeded view of the surroundings and run a cable down to your router from it.

You're going to want something with a strong radio to give you better range.

You might want to check with EnGenius They have a lot of wireless equipment and may have something to suit your needs. They're not the only manufacturer out there, but I've used their equipment, liked it, and it was the first that came to mind. I recommend shopping around and comparing and going with whichever suits your needs and gives you the most bang for your buck.

I sent a email to engenius.com LA.
I expect a reply from them not until the new year.

What you suggest, a wireless extender would that solve the connection access? eg: 7dBi versus 5??

Would it time-out (120 sec.)due to Not getting a reply from the WiFi station? iow it's signal is too weak for the distance?
Yet an IBM laptop on it's own has successfully connected from time to time.
The router antennas are rated at 5dBi each and the IBM's 2dBi.

What about IF I use 2 routers: one set as repeater and connected via RJ-45 to WAN of the one set as AP.? The laptops would than wirelesly connect to the latter?

Yes, it is a free WiFi network, they also have a variety of secure wireless networks for home and business clients.
On their website, they suggest to use their free network first, to see if one can communicate with websites online, before one commits for a 12 month contract, as they will not do refunds due to bad reception.
Their minimum charge is around $500 for the setup and a technician to check the site for signal strenght etc.
Hence I am trying to do it for less.
------------------------------
You write then you know whatever info your router is getting is incorrect and that's why it wasn't working.

I am still not sure how eg to correct the router IP address
It comes up with 192.168.1.1.

I'm going to need to see the TCP/IP settings from a client computer connected directly to the free wifi. Connect one of your laptops and once it's connected open a command prompt window (ie: Start >> Run >> type cmd and hit Enter) and perform the following command:

ipconfig /all

Once you've finished, copy/paste the output into a response on here so we can have a look.

The above is fairly normal settings and what I would expect to see as compared to what you posted initially:

The problem I am having with the router(set to "repeater" is that when It finds the network, and I click"connect" it makes me wait for 120 seconds.
Than it tells me that "successfully updated IP settings to 172.31.134.28".
This shows up as”
http://172.31.134.28/ure_success.ht...

So you could try connecting with your router again. This time ensure the WAN/Internet/External port (whatever it's marked as on your make/model router) is set to DHCP (ie: get it's TCP/IP settings automatically).

Once the router is connected, then you should be able to physically connect to a LAN port on the router and access its management interface via it's default IP in your web browser. Once connected, you can then check the external interface and see it's TCP/IP settings. They should look the same as what you posted me in your last response (what I copied above) with one exception. The actual IP Address should be different (each connected device should have a unique IP address).

Now, if your router's default IP address (check in the manual) is 192.168.1.1 which is very possible as that's a commonly used IP. That could lead to problems when connecting to the free wifi as it's using the 192.168.1.0/24 network as well.

If your router is using the same subnet, then you can change that. I would recommend using 192.168.2.1 for your LAN IP and chance your routers DHCP server to reflect that change as well. Which is to say, the DHCP servers TCP/IP settings should look as follows:

Subnet Mask: 255.255.255.0
Default Gateway: 192.168.2.1

DCHP Scope: 192.168.2.100 to 192.168.2.199

Once you've done this correctly, the router should connect to the free wifi and in turn allow your client computers to connect to the internet through it.

The router's default IP address is 192.168.1.1
I followed your instructions,
When switched to ROUTER,
I set:
IP to 192.168.2.1
DCHP range 192.168.2.100 to 192.168.2.199
Rebooted the router and confirmed that the IP address is still the same eg 192.168.2.1

Than I switched to REPEATER setting .
Waited until connection was confirmed between router and laptop over the LAN cable. I get confimation, than some 20 seconds later I get a message " Limited or no communication" And the web browser does not show the free ISP
Than I try this:
I reset in LAN properties : TCP/IP from "auto obtain IP" to 192.168.2.1 and 255.255.255.0
Again the web browser shows not the free ISP, BUT the Microsoft page
"Internet explorer can not display the page" etc..
When I disconnect the lan cable, and do a search for wireless networks, the laptop does NOT find the router, all it does find a couple of networks directly from it's own built-in antennae.

If had had a telephone line on the boat, it would be quite easy -> Just plug it into the Wan port and 'hey presto we have internet
Problem is that I 've got nothing to plug into the WAN port.
So maybe I need two of these routers: One set as router it's LAN port connected to the 2nd one's WAN port and than wireless to 4 laptops.

This however seems rather overkill, seeing a laptop on it's own can receive wireless comms.
I am just thinking out loud ...I don't know..........
All the books I found in our local library are geared toward having a physical telephone line connection to a WAN port and then wireless from there.

Many thanks.

One router should be enough to get this working. I suspect the issue may be router you're using.

This would be so much simpler if I was there in person.................LOL

The only other thing I can think of is if instead of putting the router in repeater mode, see if it has a Bridge mode and if it does, try that. An extender is a different type of device from a bridge and if your router can bridge on the external side of it, you could then use the LAN side for your own equipment.

If that doesn't work and you can, I would suggest you call the support line for the providers of the free wifi and see if they can't help you get this setup and working. Chances are they've done it before with someone else.

Alternatively, you might want to check locall for wireless providers. I live in a small town in the middle of nowhere northern Alberta, Canada and we have two wireless ISP's in our area that provide highspeed internet to all the rural customers. If you have something like that available in your area, your problem is solved. It won't be free, but it'll work and they'll come get you setup too.
