Help setting up Dlink 300T Modem & Linksys BSFR41 router

Hello, before activation can someone please advise me on how best to setup my Dlink DSL-300T Modem & Linksys BSFR41 V2 router.

I want to be able to have 2 PC's & 2 Xbox's able to use the network, to be able to access both units config menu's, to have DHCP on all 4 ports & to have a good MTU etc.

From factory default, what should I set on the Modem?
I can see I need to add my username/pw, do I need to change anything else for connection etc?

The Router does DHCP, so do I set the Modem DHCP to Off?

The user manuals don't exactly tell you much about what things actually mean.

Cheers.

Firstly you need to setup your modem to connect with Plus Net, entering your username and password and any other settings which are needed such as VCI etc.

See the following links

ASDL Connection Guide

http://www.plus.net/support/adsl/adsl_connection_guide.shtml

ADSL Settings and Install Guide
http://www.plus.net/support/adsl/adsl_install_guide.shtml


Secondly you need to setup the router, this should simple plug into the modem and your PC's and Xboxes connecting to each of the 4 ports.

Your router will handle DCHP and thus provide each PC and XBox with it's own IP.

Since this router has a NAT based firewall, when your all up and running, you may need to add some port forward rules for your Xbox games.

As for MTU, once your up and running, if you take a look at the following link
it will provide some info

Thanks Aaron, yes it helped.

Its the "other settings which are needed" thats the harder bit.
IN that I don't really know/understand what all the settings in both are for, so I do not know if tweaking any are required.

Still, I'll leave them as they are until I can get online.
My main problem then will be in geting it so that I can access both setup screens while connected through the router.

I would get the setup working before worrying about tweaking your connection.
When you say you need to get both setup screens working, what setup screens are you talking about? router and modem?

As your PC's should now be going though the router, both PC's will have access to the setup screens on the router and also the modem.

Unfortunately both modem & router config screens are at the same IP 192.168.1.1 I think.
Changing the modem to be another does not seem to give me access to it through the router.

Although I will firstly be connecting via the modem only until I have it working OK, I will soon put the router on.

Thanks.

Make sure the modem IP address is below the router's own address or otherwise you could get a conflict. I.e your modem should be 192.168.1.1 and the router should be 192.168.1.2.

If you setup the modem correctly, you should have no need to change it's settings anyway, as they will remain static.

I'm online, had a few problems but soon realised I was trying to use PPOE instead of PPOA.

Then it would not work with the rest of the phone network on so I disconnected that until I can get ADSL working (will sort that later).

Now I do not see the modem or the net when I plu the router into the modem.

Have you got filters in your phone line? these split the ADSL signal and your phone line. If you don't have them, every time you use the phone, your ADSL will disconnect

Yes I have filters.

The phone side of it I can sort easily, I am intending to rewire the house shortly anyway.

My big problem in getting all this to work, appears to be getting the router to see the modem (or getting the PC to see past the router & access the net).

Help setting up Dlink 300T Modem & Linksys BSFR41 router

OK, lets get back to basics, we need to setup each peice of equipment so it works independantly then plug them together and hopefully get you connected.
As I have no knowledge of configuring either device you may need o read the manuals a bit more to achieve what I will try to describe.

1st job is to get the 300T configured and working on it's own connected to a single PC.

- unplug all equipment and plug the 300T into a single PC which is configured to obtain it's IP address automatically.
- reboot the 300T then reboot your PC

At this point, bring up a command/cmd DOS window (start->run->cmd or command) and enter ipconfig /all and note down what IP address and DNS servers have been assigned to the PC. The IP address will probably be 192.168.1.2. If not, post what the ipconfig produced. It may be set to your PlusNet IP address, which will be fine but may change the following steps so we need to know what the ipconfig command gives.

At this point you should be able to put 192.168.1.1 in your browser and connect to the 300T's setup pages (you said that was how you get to the modems config pages).

- Setup the 300T with the plusnet login/password following the modems instructions. I don't know the modem so can't comment on other settings. Maybe find how to reset to factory defaults, then enter plusnet login details again.
- Reboot the ADSL modem and see if you can connect to the internet. If you can, that is the first stage configured. If not then that is a showstopper and you need to find what needs to be configured for it to work.

Only when the 300T is working, can we do the next step, to get the linksys configured.

- unplug the 300T and plug in ther linksys to your PC.
- reboot both linksys and your PC.

If the router is setup to supply DHCP IP adresses, your PC should be allocated an IP address.

- bring up a cmd/DOS window and posy what it now says. If it uses the same IP range as the 300T you should be allocated a similar IP address.
- Enter the IP address to access the linksys's setup pages.
- Find where the routers IP address is configured (Often refered to as the LAN address as apposed to the WAN address which is what PlusNet have assigned to you - your static IP) and change it to 192.168.0.1 with netmask of 255.255.255.0 - i.e. a different network to the 300T - this bit is important!
- Find where the DHCP address ranges are configured (probably under a section called DSCP server) and change it to start with 192.168.0.100, end 192.168.0.200.
- Configure the router to obtain it's WAN IP address automatically.

Now reboot the router and PC. You should now have been allocated an IP address of say 192.168.0.100 or .200 and you should be able to access the routers setup page by entering 192.168.0.1 in your browser.

If this works we are almost there...

Now connect the 300T to the routers WAN/DSL port.

- reboot both the 300T (1st), then the router (2nd) and finally your PC.

Now if all has gone well, entering 192.168.0.1 in your browser should get you to the routers setup pages. Entering 192.168.1.1 should get you to 300T's setup pages. If this works, you should be able to access the internet. If not, there must be some other settings in the router you need to change which I have no idea.

If tis does work, you should be able to connect your other PCs to the linksys and have IP addresses assigned between 192.168.0.100 and .200 like your first PC.

The modem on its own works fine.
Plugging the router in (requiring a reeboot) then gives me:

The Netmask of both Modem & router are the same, should they be?

After rebooting I can re-access the modem & get back here.

Doing what you have said above, I have been able to use the modem on its own, to connect to the router & acces its config pages.

However, with both connected I have not been able to;
connect to the modem config page.
connect to the internet.

Something seems to be stopping both talking to each other?
The modem is still runnig as a DHCP server when the router is connected to it, I take it that this is OK?

I'm a bit lost now, I don't really want to have to purchase a new router (matching the modem) to get it to work.
The router worked well on NTL.. (spit, spit!).

The above all looks fine and we know the 300T is configured correctly as it works. It is effectively working like your cable modem did and supplies it's WAN IP (the static IP allocated by PlusNet) to your PC's network card as I expected it to.

Again this all looks good. The change to using 192.168.0.x appears to be working as is the DHCP range change. The netmask and default gateway are also correct, pointing to the routers IP address.

I assume the next bit is when both 300T and Linksys are connected.

This is the WAN side, and again all looks fine - the 255.255.255.255 netmask is correct as it is refering to PusNets static IP assigned to you.

Again this is the IP assigned to your PC and looks good. I think the WAN of all 0's is OK but this may be an issue if my understanding is not correct.

For the 192.168.0.x 255.255.255.0 is correct, for the 80.x.x.x, 255.255.255.255 is correct.

So what you have reported looks as it should so why you can't access the net I have no idea.

One thing to look at is the MTU values set on your PC and on the Linksys. Using DrTCP, change the PC's MTU to 1478 and RWIN to 17256 (which is what I use) and within the linksys, change it's MTU to 1478 (RWIN is a windows config only). Then reboot both PC and router and see if it makes a difference.

Also try a few other tests in a DOS box:

ping 212.159.13.49
ping 212.159.6.9
ping 192.168.0.1
ping 192.168.1.1

tracert 212.159.13.49

You could try disabling it an see if it makes a difference.but it probably won't.

This is what I find strange. the 300T should just be a drop in replacement for your original cable modem which also supplied NTL's assigned IP address to the WAN port of your Linksys just like the 300T does.

My only other suggestion is to start again, but first, reset both units to their factory defaults in case there is a setting you changed that did not need to be changed. What you have should work. Maybe others can offer advice with the above info now avalable.

Thankyou so much for your advise so far.

I will try Drtcp, but I see no "RWIN" setting, how do I change this?
Is that perhaps the "TCPreceive window" setting?

Thanks.
