FashAir Connections not reliable.

[FrankNichols]

Is anyone else having problems with the FlashAir card "going to sleep" and having to be reset to connect to the network again? By this I mean it seems like if I wait a few hours after I get up in the morning to transfer the data from my FlashAir card into the computer using FlashPaP the FlashAir card is not reachable. I power cycle the card and it is instantly reachable and transfers. I can then access the card for several hours, sometimes 10 or 12 hours, and then once again it seems to drop the wifi connection - even though if I check my router, it says the FlashAir is still attached. I run the FlashAir in Station mode (5) and it attaches to my router/AP via DHCP with a reserved IP.

Thanks.

During these down times, what happens when you view the card with a web browser?

The attempt times out. If I try to ping it, it also times out.

I'm just speculating (WAG) but I wonder if the cell modem has anything to do with this. I thinking that it might divert the power to it.

Sorry!

[FrankNichols]

Interesting thought. I have a "end of compliance" meeting with my doctor tomorrow and after that I will turn on Airplane mode to disable the Cell modem and see if that affects it.

Thanks.

check these parms in /SD_WLAN/CONFIG:

APPAUTOTIME=0

STA_RETRY_CT=0

Thank you, those sound promising. APPAUTOTIME was at 300000, so maybe or maybe not setting to unlimited will help, but sure can't hurt!

But, STA_RETRY_CT I assume is retry count and setting to 0 I assume is unlimited, which certainly sounds promising

I appreciate your help, I don't know why I didn't go to their site and check all the settings, I was there the other day working on a program to read the card...

Well two hours later it's still up - we will see in the morning, I may owe you a bottle of our home made mead!

You can also set NOISE_CANCEL=0 if it isn't already. I don't know how much of a boost to the signal it gives. I had to move my wifi closer to the cpap machine and it finally stays connected. I haven't had to cycle the card in over a week now.

I can say without hesitation at this point I no longer have any problem maintaining the connection. Thank you very much for the suggestions.

I had that problem to start with and I put an access point 1/2 between my DSL modem/router and my bedroom where the CPAP machine and SD card are located. I had a few extra routers laying around and put one to good use, now the card is nice and peppy in transferring and with sdb7802's suggestions the connection has not been dropped once.

Thanks!
