Setting up modem connecting to a LAN

[Nike789]

Hi All[]
Want to know if anyone can help me, I am setting up MyWireless using an Ethernet cable. It is a SOHO, how would I do this, can I use a Broadband router and switch. If I use the BR and SW, do I need a cross over cable to get these two to talk to each other. what I really want to know is where does PPPoE come into this and how will the clients know how to get out to Internet?

TIA[V]

Hi

Not sure how the broadband router works, but if it's possible to flash the modem with the username and password (as I was made to believe is possible) then your router will work as a gateway, I think, and you only need to poit your other machines to the gateway.

Mine runs PPPoE from a linux pc/firewall and all the pc's on the network run through the firewall to the internet.

Hope that helps

Yes, you can use a router to share your MyWireless connection. Many routers also come with a built-in switch (4-port is very common), and some even come with built-in 802.11 wireless as well. In the case of a switch, you would use a straight-through cable to connect to your PC. If the router only has one Ethernet port then that would normally be configured so that it connects with a straight-through cable to a switch/hub. Having said all this, many new routers and switch have auto-cable sense so you don't need to worry if the cable is straight-through or cross-over.

PPPoE is PPP (Point to Point Protocol) Over Ethernet, and is use by MyWireless and ASDL modems. The "WAN" port of your router knows how to talk PPPoE so you don't need to know any more specifics. You would generally setup your router (often via a web interface) with your username and password, and it takes care of talking PPPoE to the modem, and the handling of connections and re-connections etc.

The client PC knows how to get out to the Internet because of the "default gateway" IP address, which should be set to IP address of your router. If you are using a router, the most convenient way to get all the TCP/IP settings correct is to configure the router to be a DHCP server, and to set all the client PCs to "Obtain an IP Address automatically". Many routers also contain a hardware firewall.

The User guide lists several modems that have been tested with the modem, but it is by no means exhaustive.

Important things are (at the risk of stating the obvious):

The modem must be set up with the USB cable initially.
Router has an ethernet WAN interface. Many, in the UK at least, use USB.
Router supports PPPOE.
Most important, router must have the option to set the MTU size. 1458 is I believe the number of the moment. YMMV.
Some sort of firewalling on the router or client machines is a very good idea.

Strangely enough, I thought the MTU was going to be a problem, but by the time I found the MTU setting on my router, I realised it was all working well:
708ort[1]pp up successfully
<b>707:IPCP up, set MTU:1460</b>
706:start PPP
705hysical line is connected
704ADS received, id:1

so, I just left MAX MTU on the router at 1500
I got the ARM904 54MB/s AP/router/switch, best value for money I've seen in a while.
In terms of PPPOE, u simply plug in user name and password, and it does it all for you.
one prob I found was that I couldn't change the default route, on the thing, and couldn't set it up to forward DHCP requests from wireless users, so I had to also configure it as the DHCP server.

Has anyone tried the Senao SL-2511SR Plus A ?[?]

This one has me stumped, dang doorstop won't connect ....[}]

Done all the basic stuff - MTU - username password etc , the green light on the modem keeps winking at me !

Signal : 11 S-N-L : 4
BER : 28% Patch - Batenna

MyDraadloos, just make sure that you have registered the modem already using USB. Also if you ever change the password for logging in you will have to connect using USB before the modem will allow you to connect using PPPoE. Then on some routers you have the option to specify the service name and logically we tend to put in Sentech. However, this seems to screw things up so rather leave this blank or put in *99#. Also just make sure that the green light on the ethernet cable is on. You can also set up the modem via PPPoE on a XP or 2000 machine no problem which would allow you to test if the modem is fine.

Good luck

Has anyone drawn up a checklist to make the MyWireless modem act as a gateway for a small LAN?

MyDraadloos, you say the Senao (etc) *A*? Can you unscrew either or both of the antennas off the side of that thing? I ask as I've been told by Gerrie at Miro (JHB) that the *new* 2511 routers, which you can tell by the ability to unscrew antenna(s), present difficulties with MyWi- he said they're waiting on new firmware to cure the problem.

That said, I *have* connected a 2511+ (not the A) and it works fine. But I think you should call Miro (0861 231 232) to really get to the bottom of this.

herbs, could you expand on what you're trying to say with "drawn up a checklist"? As it stands your question is WIDE open and can be answered with at least 3 different solutions, none of which may be what YOU have in mind!
