Access loosing connction with Acurite when Access clock is off

For the last week my Access keeps dropping it's connection with Acurite but weather underground keeps logging data from my station. The Access splash screen shows signal as a 4, and the battery as normal on all my devices. Noticed on the Access splash screen that the time listed with the connected devices was wrong. Started keeping track of the time offset. When the splash screen time is off by 6 minutes I loose connection with Acurite. Then I click the "Save and Restart" button the time gets corrected and the connection with Acurite is restored. Looks like it's time for another update.

InterestingI have one 5 in 1 showing a signal level of 0 and a last report within 1 minute of the other sensors(the 5 in 1 is my neighbor 3 doors down the street. what is odd is it used to be a 3 and neither the Access nor his roof mounted unit have moved)

I think what he is referring to is a time mismatch between the Access and the myAcurite servers.

The "connection" itself is probably fine.  However, the myAcurite server may be rejecting the data because the time-stamps are too far off "real time".

That could explain why wunderground seems unaffected... they aren't time-stamping data to wunderground (they just say the time is "now") so wunderground just takes it according to their own clock time.

Theoretically this might be fixed by correcting the clock drift in the Access and/or having the myAcurite servers be more tolerant of clock drift.

George, Correctly interpreted.
I found a work-around that works for my issue (Access clock running fast). I setup my router to assign the Access unit a static IP address with a lease time of 60 minutes. Now the Access is getting it's clock corrected when it renews the IP lease. It's been over 8 hours without a connection dropout to Acurite. Keeping my fingers crossed.

Here's a screen shot showing the problem with the Access internal clock.
If the Access clock drifts too much the MyAcuRite servers reject the data being sent, and flag your status as OFFLINE. You'll need to get the IP address of the Access hub to see the splash screen. I have my router assign the Access hub a static IP address. With the default DHCP lease renewal time of 1 day the time drifts and I go offline in 3 hours. By changing the lease time to 60 minutes the sensors stay online (2 days now). You'll have to click the "Save and Restart" button after you make the change in your router.




I did one more test and found that letting my router automatically assign an IP address (not static assigned) the sensors stayed ONLINE. 
YMMV depending on the make/model of your router.

FYI... My Access sits on TOP of a network switch with a homemade 6" LAN cable connection (Interference problems?? I think NOT)
