WRT54G with Tomato... lightning causes router to lose PPPoE

    I use DSL. If lightning strikes nearby, it causes my router to lose its connection to my ISP.

    It's very frustrating to use the internet during a storm.

    I thought it was normal for DSL to lose sync during a lightning storm, but a friend told me otherwise... So, which is it?

    Some ADSL Modems, eg Westell are so sensitive that such occurrences can happen requiring a reboot of modem. Newer 2Wire-2701HG or SpeedStream (5 Light models) & the replacemt Motorola 2210 / Netopia Business Models 3347 are more reliable in such situations. My favorites are the AR7-based DSL modems. Actiontec, DLink also makes AR7 modems purchasable in many electronic stores.

    PPPoE, being data, does not grok lightning. But DSL, being RF, does. And when DSL loses sync, that's the end of the PPP connection on top of it.

    The vulnerability will depend on the wire length and how much of it is above ground, etc.

    Having had my house struck by lightning, taking out the answering machine and satellite receiver, I would strongly advise you disconnect from the internet physically. The arrestor for the answering machine failed to protect it, no it as not one I could claim on.

    I was lucky, the arrestors for the modem saved the computer equipment, however someone I know lost his router, and the computer as the strike propagated along the ethernet cable. I did warn him, he didn't listen.

    Both cases, phone lines were overhead.
