How to make my router work with new settings ASUS AM604g

I recently bought a new ADSL+2 Router, a lovely ASUS AM604g
It worked really well for a couple of months, but then i changed ADSL suppliers to a new much faster provider.

They use a totaly different system to my old ISP, so ive had to change all the settings.

The settings I selected are

UBR without PCR

Encapsulation: Bridged Connection with LLC

Not sure what any of that really means.. but it works the router starts to recieve an ADSL singal and you can surf the web.

The only problem is it seems to disable my internal LAN, none of the other computers on my network can use the router to access the web, and even stranger the main computer can not access the router settings.

It seems the new settings activate some kind of firewalling protocals that block all incomming requests.

Not sure if this question is a bit too techinical for meta.. but any help much appreicated.

my ISP give you their own router to use (and i am right now, and it works fine) but i want to use my own, they won't help me with that.

and ASUS just told me to press the reset button.. (thanks ASUS)

This may differ on your hardware, but on every DSL "router" I've seen, enabling bridging mode means it is no longer a router; it becomes a transparent pass-through of your connection that strips off the DSL encapsulation and fowards on the TCP/IP. In other words, your DSL hardware can no longer be assigned an IP address on either side or perform any routing, and you'll need to put another router behind it if you wish to maintain your LAN/NAT setup.

Response by poster: well if what your saying is true.. it would explain all my problems.

However clearly the router the ISP provides manages to do it.. so it possible.

and the ASUS router is very good, with lots of changeable settings.. so it should be possible to make it do the same.

Sounds to me like your new ISP, having given you a router, is not interested in supporting anything but that router, and as a consequence they've told you how to use your shiny ASUS as a simple ADSL modem.

If you'd rather use your ASUS router than the one your ISP has supplied, all you should need to do is write down all the WAN settings (username, password, PPPoE/PPPoA mode stuff) that your ISP's router is currently using, then reset your ASUS router, connect your PC to it directly, get back into its management page, set up everything as your ISP told you to except bridging mode, then make the ASUS WAN settings match those from your ISP's router.

Response by poster: ah the settings are hard to get out of the isps router.. i think its a closed box.

The problem is this ISP is the greatest ISP in the whole of the UK, its like 10x faster 10x cheaper, and truely unlimited. So theres no option of going anywhere else.

Best answer: OK. Let's work through this one step at a time.

Could you please describe for me, in the most excruciating detail you possibly can, how the working setup involving the ISP's router is put together? I want to know what ports on what boxes are wired to what with which kind of cable, what's in Network Connections on each working computer, any identifying make, model and preferably serial number info you can find on both your routers, and the results of opening a cmd window on each computer and entering the commands

ipconfig /all
route print

There is no question too technical for AskMe :-)

OK. You still haven't told me who's wired to which with what, or given me any model numbers to work with, so I'm going to make some assumptions. Please check these and tell me if any are wrong.

1. The setup you used to generate those reports is successfully connecting a single computer to the Internet.

2. There is one device connected to an Ethernet port on your computer.

3. That device is the router your ISP gave you.

4. Your DSL-enabled telephone line is also plugged into that router.

5. Under Network Connections, you have both a Local Area Connection and a DSL connection listed.

6. When you first switch on your computer and fire up your browser, you get a prompt that either asks you which connection you want to use, or mentions the DSL connection and has username and password boxes and a Dial button, and you have to click the Dial button to establish an Internet connection.

As well as checking these assumptions, could you try pointing your web browser to http://192.168.1.254/ and see if you get some kind of status page? If so, what's on it?

Response by poster: yes its an isp supplied router

SpeedTouch 780
firmware: 6.1.4.3

OK, so we now have a make and model, and assumption 3 is correct. What about assumptions 1, 2, 4, 5 and 6, and the result of browsing to 192.168.1.254? A screenshot would be good.

There is indeed no question too technical for AskMe, but expecting it to work by telepathy is unreasonable.

Response by poster: telepathy isnt needed..

Id already said the isp supplied router works just fine... dsl/lan/ethernet everything as you would expect from a normal router... So its a yes to all the other questions too.

Best answer: OK. So now you can access the router settings.

I would personally not expect assumption 6 to be true for a "normal" router, which is why I got you to check the assumption. I *would* expect it to be true for a router in "bridged" mode, i.e. one that's acting as a straight DSL modem and has its router brains switched off.

Here is the product information page for your ISP's router, which has links to the setup guide and the user manual.

I suggest you back up your current configuration (see page 60 of the user manual), then fartarse around with the Internet settings until the router can establish an ADSL connection and log on to your ISP account without needing your computer's involvement to do so.

Get rid of the Windows Internet Gateway nonsense; use only the router's admin web server. The only interface you should need in Windows' Network Connections control panel is your LAN connection.

Once that works, you should be able to connect multiple computers and they should all function.

Then you can simply transplant the same settings into your ASUS router, and use that instead, if you want. I must say, though, that based on a glance through the manual, the SpeedTouch unit looks like quite a decent bit of kit, and I'm not sure what the ASUS will give you that the SpeedTouch won't. The SpeedTouch also has phone ports on it, and if you want to get into VoIP you're generally better off dealing with one box than several.

Post back here if you get stuck.

Response by poster: I contacted my isp and they got back to me with the settings they should work.. they still don't really make much sense to me.

They say the settings should be:

VPI:0
VCI:101
Encapsulation: LLC based
Modulation: G.dmt 992.5 An.A
DSL con.mode:RFC1483 bridged
DHCP with no username and password
DNS Primary:87.194.0.51
DNS Secondary:87.194.0.52
