Interesting Support suggestion

[CDB-3]

 I've just changed over from cable to ADSL2+ connection.

I've got massive problems with dropouts and the modem freezing. I have
a spare modem which doesn't drop out, but can't be used as the
provider refuses to register my routers MAC number.

I've sent logs, made notes of when it drops out and crashes
(suspiciously it does it between 4am and 11 am, fine during the
afternoon until about 11pm) anyhow just got off the phone from one of
their techs - their remedy is to have the Linksys modem standing
upright rather than flat. They are positive that will solve the
problem.

Whilst temperature may well play a part, they haven't quite sussed
that at 4am and up to about midday the temperature in my house is
about 16c in the afternoon it is 22c and then drops after about 5pm
when the sun disappears. So if it is overheating it ought to play up
during the hot time of day not the cold.

The damn thing keeps giving itself a warm reboot which wipes all the
logs.

Why they can't just take the Linksys router back and accept my Draytek
all singing all dancing device I don't know.

I felt like asking if they thought the electrons need to be the right
way up!

Just set the mac address of the working router to be what the mac of the
linksys is.
most modems out there support "spoofing" of mac addresses.

We had similar problems when we first got ADSL. Eventually after
multiple complaints Telecom manged to find a crossed pair in out
cable. All fixed. But prior to the fix they claimed to have tested the
cables several times and all was reported well. As for time of day, I
guess in our case it corresponded with interfering traffic.

And yes, many routers have the capability to have thier MAC addresses
changed. Or you may be able to put the ¨good" router in bridge mode
and run the¨bad¨ one off it. Think that might work but not sure.

Tried that doesn't work. If I leave out my static IP address I get to
their website but no where else.  I think they download a
config/security certificate which obviously my Draytek won't have.

I've had dealings with actual Cisco routers and I know the
organisation always downloaded config certificates.

I've seen "interesting" things happen like this in the UK when the street
lights come on.

One member of our ADSL provider always got cut off at the same time and it
corresponded exactly to the turn on of their street lights.

Maybe it helps to better distinguish between modem and router (even
though they are often in the same case).

I used to have an ADSL connection that came with a D-Link modem/router.
But I didn't use the router portion of the D-Link; I configured the
D-Link in bridge mode (so only the modem portion is active) and hooked
it up to my Draytek router.

The disadvantage of this setup is that in order to get to the D-Link's
configuration pages, I have to connect it to the LAN side of the
Draytek. (In normal use, it's of course connected to the WAN side of
it.) The advantage is that I got to use my normal router.

This may help if it's the router portion that freezes.

Agreed. In fact I'd recommend most people do that. While the "router"
portion of most ADSL modem/routers is decent, you can get FAR better
performance and stability using your own router.

I highly recommend any router that can be flashed with dd-wrt. It is an
AMAZING distro, with features pretty much no "consumer" router has.

Hmm since 6am this morning 22 dropouts and it is now 7:13am.

What is interesting looking at the log is that the Linksys free RAM
decreases.

My setup is Linksys WAG54G set up as ADSL modem is connected to the
phone line (this is a NAKED DSL line) the gateway address for the
router is fixed by the ISP as is my static IP.

My Draytek Vigor 2820Vn has two WAN ports WAN 1 for ADSL connections
and WAN 2 and USB for anyother WAN type - both can co-exist. The
Draytek ADSL internal modem is disabled so the Linksys is connected to
the WAN 2 port. The Draytek is DHCP server

If I plug the phone line into WAN 1, I get no disconnects and the SNR
is about 13dB with a down line attenuation of 42dB.

The Linksys  SNR (they call it Downstream Margin) varies between -5
and +5dB with an occasional excursion upto 12dB - attenuation is 44dB

The Tech Support will not consider my argument that the large
variation in SNR between the two devices when connected direct to the
phone line is so large that the Linksys is either faulty or has a poor
front end modem design.
