SR101 to two Linksys X3000 Router help, one network setup

[lukedobson]

Hi,

I want to connect two additional Linksys X3000 routers to the Sky SR101 as the default gateway, all under the same network, same subnet.

Have moved to sky from Virgin just a month ago as we have just moved house. Being on cable broadband before, I never knew how complicated it has got now on ADSL. So my old routers, only a couple of years old, are now of no use due to the PPPoA. So I went out and purchased two new Linksys X3000 routers.

Upon setup with the CD provided with the X3000, it automatically connected to the SR101 via WAN to LAN, and on RFC2684 Bridged. However when I tried to change the IP from 192.168.1.1 to 192.168.0.2, it connects for the first time wirelessly via my laptop, but if I try to disconnect and reconnect, then I come into all sorts of problems. All of a sudden it will throw back a 169 address to my iPad but the correct settings to my laptop, but the DNS server won't respond, so I am connected to the network but not internet access.

I have tried everything, searched every forum for the answers but I just can't work this out. I have tried spoofing the MAC, i've extracted the password and username from the SR101 via Wireshark, changed the setting to RFC2364 PPPoA, changed the VCI to 38, then to Auto, tried DHCP relay, or turned it of completely, tried setting up Static IP addresses for MAC reservation. But nothing seems to work. What am I doing wrong?

Regarding the DHCP settings, is it best to separate the IP pools between the three, ie. 0.2-0.99, 0.100-0.149, 0.150-0.199? Or relay the DHCP to the SR101 as DHCP Server?

Any help is greatly appreciated. Its been up for a month now and still can't use it to the full. I get 12mbps from wired connection, but only 2mbps from the wireless connection the Sky Hub. when the X3000 works before the connection dies, I receive 12mbps too wirelessly.

Oh and all wired connections from the X3000 works no problem too, at 12mbps.

So this is what I am trying to achieve:

SR101 {192.168.0.1} <WAN> to <LAN> X3000 {192.168.0.2} <LAN> to <LAN> X3000 {192.168.0.3}



Thanks!!

Luke


EDIT: Forgot to say, another possibility, it seems as if the X3000's are struggling to obtain the DNS and Default Gateway data and whatever else, from the SR101. Could it possibly be the SR101 holding back passing the info on to the other routers?

Have you taken a look at this post?

You should probably use the SR101 as the DHCP server, turning this off on the other routers.

Yes I've read through that forum and others relating to that but after trying what's been said, still can't get it to work. I still think the difficulty is with the sky hub.

Thank you for your advice though

If you want to run it as one network, you will have to connect ethernet to ethernet, not using the WAN ports on the Linksys'. Ensure that the DHCP servers are turned off in the Linksys' and they both have addresses in the range of the Sky hub, 192.168.0.250 and 251 for instance. That is about all you have to do.

That's the thing, I am only using LAN to LAN to connect the two routers to the SR101. I can connect to the network no problem. The problem is internet access. That is the issue I'm having. I'm not a technician when it comes to networking, but I have learnt a lot over the years, but never known something to be so complicated like this, when it should be a simple process

I'm sorry, but your mention of this -

Upon setup with the CD provided with the X3000, it automatically connected to the SR101 via WAN to LAN, and on RFC2684 Bridged

suggests you are not connecting ethernet to ethernet. If you connecting ethernet to ethernet and disabling their DHCP servers you are cutting out the router functions of the Linksys routers completely. You are infact using them purely as switches. There is no reason why it should not work.

SR101 {192.168.0.1} <LAN> to <LAN> X3000 {192.168.0.2} <LAN> to <LAN> X3000 {192.168.0.3} You would have to reserve these addresses in the SR101 or they are likely to be given out to other devices by the DHCP. That is why |I recommend you use high numbers such as 250 and 251. There is a good chance .2 and .3 is already allocated to other devices, giving you more problems.

Oh I understand, so what should the router setting be set as if it isn't RFC2684 Bridged?

With regards the IP addresses, the routers are assigned on the SR101 as well as the other devices which I don't move around like printers and TV etc, they all have static IP addresses.

Thanks it really helps!! A step closer to fixing this

I could be wrong, but doesn't that bridged mode still use the WAN port? I'm not sure on the interface for the linksys, but can you set it to turn ADSL off or put it in to an 'ethernet' mode

[Isitme]

Oh I understand, so what should the router setting be set as if it isn't RFC2684 Bridged?

As you are not using it as a router, rather a switch, there is no need to set any mode for the router. Just ignore these settings as they don't come into play unless you are using the WAN port.

Right,

So I have changed both routers to Ethernet only, so it's more like a daisy chain. Both X3000 routers are now outside of the DHCP settings on the SR101 to stop any IP conflicts.

So far, anything connected via Ethernet cable from the X3000's is absolutely fine. Wireless is a different story. One laptop work, and so does a printer with wireless.

However....

3 other laptops are connecting fine, but not receiving any internet connection. They all have the correct DNS settings, IP addresses and subnets, but no internet access.
Our iPad's and smartphones all throw back a 169... IP. So somewhere down the line, they aren't talking to the SR101 somehow, and now it's been a couple of weeks and it's still not working.

Biggest pain is the 2mbps limitation on the SR101

Any other suggestions?
