FlashAir Problem?
#11
What about the radio? I have a setting on mine to disable the wifi radio during certain hours. Long shot but worth a try.


Using FlashAir W-03 SD card in machine. Access through wifi with FlashPAP or Sleep Master utilities.

I wanted to learn Binary so I enrolled in Binary 101. I seemed to have missed the first four courses. Big Grinnie

My AP has that capability, but the radio is enabled 24/7.

Your DHCP IP address may be expiring. Try reserving an IP address on your router using the IP address of the FlashAir when it is working and the FlashAir's MAC address located on the back of the card.

Excellent guess, and would certainly cause what I'm seeing, however I have a DHCP reservation for the card....

!
ip dhcp pool Static
host 192.168.1.9 255.255.255.0
client-identifier 01b8.6b23.b8b0.9c

Apparently, it was a signal strength issue. I rotated my upstairs AP by 90 degrees, and no more disconnects - only been one day, but this is longer than it has run in a while. So much for BeamForming technology Wink

Thanks,

Tongue Suck Technique for prevention of mouth breathing:
  • Place your tongue behind your front teeth on the roof of your mouth
  • let your tongue fill the space between the upper molars
  • gently suck to form a light vacuum
Practising during the day can help you to keep it at night

Thinking-about That's pretty bad for 20 feet. My AP is at least 45 and often behind the TV stand, thanks to my cat. He just does not like it on the TV stand. What kind of AP is it?

Thanks, Daria Smile

Alan,

I have 2 ASUS RT-AC87R APs. The latest and greatest AC2400s from ASUS - all the reviews say "best range" yadda, yadda.

Anything like an older iPad or iPhone running in the 2.4 Ghz band gets 5 bars sitting next to my CPAP machine. So I'm thinking that the FlashAir inside my CPAP has less than optimal RF capabilities. And it clearly does not have BeamForming capability, even though the AP does.

Since SD cards are only about 1" wide and maybe 1.25" high there is not much room in them for an antenna. A quarter wave at 2.6 Ghz is about 3 centimeters or just over an inch long. There's no way you are going to fit a directional antenna in that space along with a storage chip and a radio chip. It will radiate, but not very efficiently and will be pretty omnidirectional.

Agreed. Still amazing it works at all given the size of the SD card versus that of a "normal" AP.
