>From an ISP point of view I much prefer an external router to an internal
modem, or USB modem.

In my experience:

Zyxel routers, virtually never have problems. I have had to restart maybe
two Zyxels ever.

Ditto with the Cisco 82x's that I have used. I have never had to reboot a
Cisco to fix a DSL issue.

D-Link, really depends on the router. Some work and work, others need the
occasional restart. I think the problems are getting better with the future
firmware releases. I have not had to restart anyone yet with the latest
DLink firmware, but thats only been around for a bit

Dynalink... RTA020 was dodgy as *&^%
RTA210, the ones with the fixed capacitor (?) after the recall seemed pretty
good. Again, they need occasional rebooting.
RTA220, Dynalinks latest offering. I have never had to reboot one of these
to my knowledge.

Plexuscomm and DSE routers (these are really just the same router with
different firmware I think)... I hate these a lot so won't even comment on
them.

Alcatels and Micronets I have never had much to do with.

Does anyone know where the problem actually exists? Is it a problem at
Telecoms end which a hard reset fixes (I actually doubt this), or is it just
dodgy modems and firmwares at the customers end?

Anyone disagree or want to comment on this? Flame away :)

If its not of use to anyone else, reply to me offlist.

Subject: Buggy ADSL modems - the norm ?

Hi All,

I'm curious to get a bit of feedback from anyone involved with external
ADSL modems and their reliability.

 From an ISP point of view it seems to me that external ADSL modems are one
of the most unreliable things going :)

I'd say the vast majority of tech support related issues we notice with
Jetstream is simply that a customers ADSL modem has either stopped
responding or just plain gone "funny", which is invariably "fixed" by
restarting it.

Symptoms range from the modem dropping the connection and not reaquiring
it, but seeming ok in other regards, to the built in web interface failing
to respond although you can still ping it, right through to total
unresponsiveness across the network.

Typically a modem will last anything from a week to a month before one of
these symptoms occurs. I've seen a couple of "no-name" brand modems (quite
literally) that can't last more than about 2 weeks without a power cycle.

The disapointing thing is that I'm seeing this on nearly all brands and
models of modem/routers that I've encountered... including Dynalink, Nokia,
D-Link etc..... so my question is

does *ANYBODY* make an external ADSL router/modem that can stay up for more
than a month without crashing and burning ? :)

Or, does anybody have any information on which brands and models of
external ADSL routers/modems are known to have this poor-uptime
performance, and any models and brands that are known to be particularly
reliable. (In terms of high uptimes without "funnies", or needing a reboot)

Regards,
