LaCrosse Wireless Internet Gateway Model GW1000U ERF-100
keckec:
My GW-1000U stopped working a few weeks ago. I tried the factory reset several times, but didn't help. On http://support.lacrossealertsmobile.com/articles/gateway-troubleshoot-replacement-parts Lacrosse says the gateway may stop working after several years. Yikes, that's planned obsolescence for you!
On a hunch I opened the gateway up and found a MX25L2005 flash chip inside. These have a 100,000 write-cycle endurance, and I have my gateway configured to save history every 5 minutes. This would use up the write cycles in a little over a year, and mine is about four years old. I replaced the flash chip with a Macronix MX25L2006E, did a factory reset and re-registration, and it's all working again. The part was less than $5.00 including shipping from Digikey Electronics. At that price, I'll order a couple of spares.
BY the way, the PHP code referened way earlier in this thread worked just fine for re-registration, and I have packet captures of it all if anyone is interested.

keckec, thank you! I just got some replacements. Do you know which of the three SOIC8 ICs it is, along with which pin is #1? The factory burned off the numbers on mine, and I can only tell pin #1 on the bottom one:
