Hi everyone,

I'm on a very steep learning curve regarding home networks. Not completely ignorant, but far from an expert.

In a very short space of time, I've progressed from an Apple Extreme basestation + Slingshot free modem (no QoS and modem overheated regularly) to a hideous WAG54G2 (reset itself to bridge every day), to a WRT54G with Tomato firmware + Nokia M1122.

All this was done in a search for decent QoS, because my boarder hogs the bandwidth whenever she is running Skype, which is pretty much all the time.

After reading Ben Gracewood's guide to setting up a WRT54G and RTA1320, I finally managed to get my old Nokia M1122 talking to my WRT54G. I've finally got wireless internet, after several days of trawling through websites and getting out several books on networking from the local library (not much help). I'm not a networking genius, really just seem to get things working through trial and error. The technical books are way above my head, and the "Networking for dummies" type books rely on someone running XP or Vista and running set-up CDs, neither of which is applicable to me.

I know the M1122 is an older modem, but extremely good. They don't get hot and are very stable. I bought it for $1 off trademe because I've been waiting on a Linksys AM300 to arrive for about 2 weeks now and got tired of waiting. Considering the fact that Dad bought an M1122 new for $690 + GST years ago, I got a good deal!

I've read a thread on a linux forum that states that the M1122 set to PPTP is better than half-bridge, but I have no idea how to set it up so it talks to the WRT54G. I've tried several times without success.

My internet provider is Slingshot, and speed tests via speedtest.net and slingshot never seem to get much above a download load speed of 6 Mb/s and upload speed of 0.3 Mb/s.

Is there any advantage in using the M1122 set to PPTP over using the AM300 on half-bridge (when it arrives)?

If so, could anyone tell me how to basically set up the M1122 with PPTP so it talks to the WRT54G?

Pardon my ignorance,

Harry

Ok I think you mean PPPo-A not PPTP. PPTP is a type of VPN and PPPo-A is Standard ADSL.
Now you don't need to setup the Nokia in Half Bridge mode but if the nokia does have a DMZ mode then I would set that to point to the WRT54g.

Basically you need to have the WRT setup with the Wan port on 1 IP address range and the Lan on another. I.E. Wan IP 192.168.1.1 Lan IP 192.168.100.1.

Now the Nokia needs to have its Lan IP set to the same subnet range as the WRT Wan range. I.E.192.168.1.254 and in the WRT you will set this address under the WAN Gateway IP.

On you computer you should then be plugged into the WRT or using Wifi either way you should be getting an IP of the 192.168.100.2-254 range and your gateway should be that of the WRT I.E. 192.168.100.1

Then you should be good to go.

If you have any problems let me know.

The nokia does a mode where you PPTP into it and get the real IP address.

It works fine, but IMO using an old ADSL1 modem will really screw with your speeds, so is at best a stopgap till something better arrives.

I dont have the M1122 here with me anymore, its in a box in the shed and I dont have a power cable to fit since I gave it away with an old laptop, but from memory there was just an option where you set the VCI and VPI to choose for PPTP, and then you VPN'ed into the router with your ISPs authenication details. I used it with the VPN client in windows without issue, and then changed it back to NAT mode when I no longer needed the real IP address on the computer. A friend tried it with an old linksys router and it also worked fine, but not all have PPTP as a wan option on them.

Thanks for that. Actually, I haven't noticed any slower internet speeds now that I'm using the M1122. The WAG54G2 I had before was actually slower, and that was ADSL2+.

Dad had a M1122 some years back that often downloaded at 24 Mb/s, so the machine itself isn't slow, just the physical connections between the modem and the local server. He had a tame Telecom technician redo every connection between the modem and the local exchange.

Anyway, I'll see if the AM300 is any faster and go from there. Thanks for the info!

Cheers for the info. No, I meant PPTP. As far as I know the M1122
doesn't do half-bridge, but PPTP was, according to one site, a better
option. I have no idea, but seeing as I have an M1122, I thought I'd try it. Unless the Nokia calls DMZ something else, I don't think it
supports that.

I'd already set the router and modem up as you suggested, although for some reason I have to turn bridging and NAPT on under the M1122's "Service Provider Settings" tab. If I turn NAPT off, the net slows down dramatically. If I turn off bridging, I lose internet via the wireless router. The M1122 doesn't have an NAT box to turn off, which Ben's routing solution recommends.so I tried turning off NAPT, with negative results.

So it's up and running, but whether it's running at it's best I don't know.

I'll see how I go once the AM300 gets here. I can't see it being any faster than the M1122, as my download speed max's out at about 7Mb/s and the upload is about 0.25 Mb/s on a good day. That's been the case with each of the 3 set ups I've had over the last 6 months. I presume the bottleneck is in the cables to the local exchange.

Cheers for all the info,

Harry

If you are getting 7 megs on adsl 1 gear, then there is a very very good chance that you are very close to the exchange/cabinet so that adsl2+ stuff would give you much more. Unless you are on xnet who like to limit peoples speeds arbitrarily for no good reason.

No, I use Slingshot at the moment, but my pig of a WAG54G2 was ADSL2+ and it wasn't any faster than the M1122.

When Dad had an M1122 up near Auckland it would download at 24 Mb/s but he had a tame Telecom technician who optimised his connection to the local exchange.

I don't know if Telecom's going to ADSL2+ a few years ago will have had a detrimental effect upon the M1122's connection speed, but it's no slower than the WAG54G2, so I don't have any great hopes that the AM300 will be any faster.

But then, I'm guessing you know more than me about all this, and to be honest the WAG54G2 was a dog.

Regards,

Harry
