Question

LinkSys with Aztech problem

Asked by: PstWood

I have a problem similar to the one at: http://www.experts-exchange.com/Networking/Broadband/DSL_Cable/Q_21214820.html?query=aztech+305eu&clearTAFilter=true

The ISP here in Argentina provides an Aztech DSL305EU modem router with their broadband service, however they won't help configure it for use with more than one computer unless you pay extra money (lots). If you want to hook it up to more than one, you're pretty much on your own. Consequently, the Aztech is set up as a dhcp server and to dial using the username and password.

This same ISP used to give a Cisco DSL modem with their service and expected you to use software to dial out which was always dropping the connection. A Linksys 4 prt router and switch set up to use PPoE and dial the number works fine. I have a network that's been working with that system for over 4 years without a hitch. I thought I could do the same with the Aztech, but I can't get it configured to allow the LinkSys to dial out, although it is supposed to be able to.

I've also tried setting up the LinkSys as a dhcp client to the Aztech, letting the Aztech do the dialing work, and that seemed to work, but the connection drops after a few minutes and won't reconnect unless I power off the router and modem and power them back on again.

I have 3 networks to set up with this system, so this one merits all the points, even if the solution is easy.

Thanks.

If you want to use the linksys for pppoe, you need to put the aztech into bridge mode. Both cannot have pppoe enabled at the same time.

 

by: PstWoodPosted on 2005-10-26 at 14:16:04ID: 15166763

I have tried this a number of ways: with the Aztech in bridge mode connected to the Linksys via the Linksys WAN port and with the LinksSys doing the "dialing" of PPPoE. The connection gets made, but then degenerates to the point where client machines either get page not found errors or load pages slower than they would over dial-up.

I've left the Aztech in router mode, configuring it's dhcp server to hand out IP's to all clients via a hub (not router) that is connected to the Aztech via the hub's uplink port. Same scenario: initial ability to navegate, but then the connection gets dropped.

I've tried having the Aztech in router mode with the LinkSys switch/router getting a dynamic IP from the Aztech's dhcp server, and I get the same scenario.

I've tried the Aztech/Linksys router setups above with more than one LinkSys to try to rule out that one was bad, but it's the same. The only stable connection that I've been able to get is with the Aztech connected to just one machine.

If anyone has any solution, I'm willing to post a "dummy" question for another 500 points.

Thanks.

Does the Aztech have a line status page?

It may also be a network problem where the isp uses a proxy server to throttle traffic.

 

by: JonShPosted on 2005-11-01 at 10:18:47ID: 15202152

Since the line comes up and then degrades, my first inclination is to see if it's a timeout/inactivity issue.  The cheap/dirty way to do that is connect the aztech to the isp, linksys to the aztec, pc to the linksys.  See if you can run a ping all the way to the outside world, maybe to cisco.com or something.  If you get that connectivity, try a ping -t cisco.com and see how/if it dies.

 

by: IanThPosted on 2005-11-01 at 11:02:51ID: 15202616

your isp could be testing for thier own device and when not found degrade the service to make more money maybe

 

by: PstWoodPosted on 2005-11-01 at 11:27:13ID: 15202838

OK. After much putzing around with this, I got it to work, and surprise, surprise, it worked as I thought it should have originally. I'm not sure why it didn't at first.

The Aztech could be configured as a router and dhcp server, hands out IP's to clients, everyone gets on the net, and it works fine. The LinkSys is not needed, only a simple hub between clients and Aztech.

I'll divide the points between those who responded.
