ADSL sync fail, internet still works

Ok, I need some help since I am kinda new to DSL. My internet works fine except that the DSL goes out randomly (about once per day at random times), but with a reboot of the DSL modem, it works again. In addition downloads of large files seems to stall quite regularly. Was working fine a few weeks/months ago.

AT&T tech support says the modem looks fine when they diagnose it remotely.

Info is below (sorry, I can't find the standard info template at the moment):
Macbook Pro computer
No router
Pro speed (up to 6Mbps)
Westell DSL modem that AT&T provided
No phone line, DSL only, nothing else connected to the phone lines
speedtest.net shows 5Mbps download consistently (which is normal for me)

Thanks in advance for any assistance,
Brian

Found it!
1) Which AT&T DSL Package do you have –
Elite (6.0Mbps down)

2) Which modem brand and model do you have? Westell

3) Are you using a router? If so, provide the brand and model. No

4) Is your PPPoE login info (username & password) entered in the modem, in your router or do you use PPPoE software? modem

5) Describe the lights on the modem when the trouble occurs. looks normal. Sometimes I get red lights as the modem is turning on

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. No other devices

7) Confirm that you’ve powered off the modem and started it again and whether or not that made any changes with your problem.
Rebooting the DSL modem resolves the outage but does not resolve the downloading problem.

8) Do you hear any type of noise on the DSL phone line or any other unusual telephone symptoms? N/A, no phone line

9) Provide line stats as follows…

d) From a Westell 6100 -- Go to this address with your browser - »192.168.1.254/html/statistics.as···ance=106 and copy/paste the contents of the first two tables into your post

See above for entire set of tables

10) If you have a speed problem, use the AT&T Speed Test here -- »helpme.att.net/dsl/speedtest/ and post your results.
3/31/10 -- While the AT&T Speed Test site is undergoing renovations, try this site -- »www.speedtest.net

Speedtest is normal ~ 5Mbps when DSL is working

Ok, I called tech support when the DSL went out again, they have no idea what the problem is it seems so they are sending me a new DSL modem to try. I checked the log in the modem and found this repeated over and over again:

2011/07/13 00:57:31 EDT ERR | net_mgr | PPPStartStop: Fail to connect PPP PID(250) errno(3)
2011/07/13 00:57:32 EDT ERR | net_mgr | SIOCGIFFLAGS ioctl failed for ppp0
2011/07/13 00:57:32 EDT ERR | net_mgr | PPPStartStop: Fail to connect PPP PID(250) errno(3)

I also discovered that instead of rebooting, I could just click on the reconnect button on the modem settings page. Then it works again.

I hope this is not a line quality problem.... it was working fine for a month or so.
