I've been purchasing the cheaper version of the SV92P modem. I can't use the one sold here because it doesn't like MultiLink. The cheaper versions, wich are more likely to fail, work great with the newest drivers and with multilink. The problem is that they get screwed up by lighting all the time. I've lost about 4 in past 6 months. i even have 2 lighting protectors connected to each phone line, a total of 4. Yet, lighting still messes them up.
I never get a hardware error though. I just get the no dial-tone message from windows. When I manually inspect the modems I see now blown capacitors an no burn marks. Does anyone know what exact part of the modem goes out due to high static charges or lighting strikes?
I have to keep purchasing new modems over and over again.
And I can't leave them unplugged. I can leave 1 unplugged but the other must stay plugged in for the other phoneline to work in the house. I have it wired up a certian way and can't change it.
Or maybe someone could recommend a surge protector for modems that actually work?

It would certainly cost more to obtain the bad (parts) and replace them on the modem card than it would to purchase a new modem.
As for protection - if you search groups.google.com for comp.dcom.modem posts related to lightning/modems, you will find numerous posts by 'tomw' who claims the only way to provide protection is whole house/earth ground - however, I don't believe even that would work with these kind of modems because phone lines are balanced (neither wire is at ground potential), and telco protectors which shunt to earth ground are not sensitive enough to protect the 'delicate' line-powered DAA in these modems....

I had to chuckle reading this thread because I have a neighbor I gave 3 SV92P modems all gone up in lightning storms one after another. After going through all 3 I bought her eight more! When asked why mine never dies I reminded her of my earlier advice to unplug the phone line when you hear thunder.
Richard is right, these things are so cheap you're better off just throwing them away. I think the last batch cost under five dollars each including delivery.
