AT&T DSL...slow speeds...router issue?

Hi everyone. I am enlisting the help of the wizards on these forums because I know just enough to screw things up. I recently have gotten DSL service. I had an older NetGear modem that I attempted to use to no avail. I bought the "supported" Motorola 3360 modem from Walmart and initially had success with it. I have been using a Linksys WRT54GS router forever. I had set up the internet with my login and network password on the modem AND on the router (odd?). But recently the internet slowed down to a trickle and it appeared the lights were having a party on my modem and router, with no input from me.

I called tech support and they ran me through a few circles. We determined that either the router or the modem should have my login info, but not both. So we tried it in either arrangement, both to no avail. Her best suggestion was that there seems to be a problem with the router. I tried to change router firmware today from DD-WRT to Tomato, etc. No luck. Off to Best Buy. I picked up an ASUS N750 since nobody in my house has the AC standard and I really didn't feel like spending $200 on a router. I followed the directions and it seems the same crap is happening. But now I can at least get 1.8-ish Mbps download speeds, though it still seems sluggish. FYI, when I plug the network cable directly to the laptop I can get 2.5-ish speeds immediately.

I still blame this on AT&T's odd proprietary B.S. or on DSL in general. I never had these issues with a cable or fiber-optic set-up. Anyway...here's my specifics:

1) Which AT&T DSL Package do you have – I pay for very basic service...3.0 Mbps down.

2) Which modem brand and model do you have? Motorola 3360

3) Are you using a router? YES If so, provide the brand and model. ASUS RT-N65 dual band

4) Is your PPPoE login info (username & password) entered in the modem, in your router or do you use PPPoE software? It's on the modem, but I tried running it in bridge mode and the damned modem seemed totally unresponsive with no IP address.

5) Describe the lights on the modem when the trouble occurs. The Lights appear to be functioning correctly...4-5 lights on or blinking.

6) Confirm that you’ve checked to ensure that ALL devices plugged into the wall jacks serviced by your DSL phone number (except the DSL modem) have filters fitted. I use no filters because I don't have a phone line.

7) Confirm that you’ve powered off the modem and started it again and whether or not that made any changes with your problem. I have tried this several times. It does not seem to change anything.

8) Do you hear any type of noise on the DSL phone line or any other unusual telephone symptoms? I have no phone lines and can hear nothing.

There is nothing proprietary to AT&T's legacy ADSL (PPPoE is only used with that).

1) Which AT&T DSL Package do you have – I pay for very basic service...3.0 Mbps down.

Before U-verse HSI was deployed, that was called, "at&t Yahoo! HSI Pro"; 3008/512 for down/up sync.

4) Is your PPPoE login info (username & password) entered in the modem, in your router or do you use PPPoE software? It's on the modem, but I tried running it in bridge mode and the damned modem seemed totally unresponsive with no IP address.

A bridged modem does not have the public IP address, that will go to the WAN side of the router. The bridged modem is not accessible from the LAN because of the PPPoE encapsulation done by the router. The easiest way to access the GUI of the bridged modem is to connect a stand alone computer directly to the modem.

9) Provide line stats as follows…

e) Motorola 3360:

DSL Information

To Modem To Internet
Data Rate (kbps) 3008 512

Line Attenuation (dB) 47.0 27.0

LAN Information
Modem IP Address 192.168.1.254
Modem Netmask 255.255.255.0
DHCP Address 192.168.1.64

SNR and attenuation are good; shouldn't be a cause for problems.

I see a potential problem with the private IP addresses; and Netgear would actually force a change in your situation. The modem is reporting that your Linksys has been given IP address 192.168.1.64. The default IP address on the LAN side of the Linksys is 192.168.1.1. This means both sides of the router (WAN and LAN) are in the same IP address block: 192.168.1.0/24. As I said, Netgear would force a change on the LAN side to resolve potential conflicts; Linksys does not. I suggest changing the third octet to any valid value, other than '1', on the LAN side of the Linksys. 192.168.2.1/255.255.255.0 (IP Address/Subnet Mask) would work.

Before I make changes based on your recommendations, allow me to clarify. I do not have the Netgear modem hooked up any longer...I switched to a Motorola 3360. Also...I bought a new Router. So no longer am I using the Linksys WRT54GS. I am now using the ASUS Router. It was getting old and did not even support the N standard.

My router noticed a similar IP address and switched itself to 192.168.2.1 My modem is still on the 192.168.1.254 IP. To be honest, most of this does not make a ton of sense to me. Otherwise I suppose I wouldn't be on these forums.

Thanks in advance for you help.
