FlashAir Bandwidth Limitation
#1
FlashAir Bandwidth Limitation
I came across this tidbit of knowledge while playing with my FlashAir. The Toshiba FlashAir is limited to a 20Mhz maximum bandwidth. Some WiFi access points have the ability to adjust this size. The newer WiFi access points have a default of 40Mhz, with an option to enable 20/40 MHz coexistence. This option is located somewhere in the 2.4Ghz parameter section. Netgear has this parameter located in the Advanced->Advanced Setup->Wireless Settings. The FlashAir will either not connect or have connection problems if the bandwidth is set above 20Mhz.

What the bandwidth setting does:
The greater the bandwidth, sometimes listed as: "Channel Spectrum Width", can be used to control the channel width consumed by your link/device. Using a higher channel width will increase throughput. Using a lower channel width will allow an increased number of channels to be used (including more non-overlapping channels). Lowering channel width may also provide more robust links over long distances.

I hope this may help someone.

Nice find. I have an 'old busted' wifi router. You must have the new hotness. Smile
Using FlashAir W-03 SD card in machine. You can download your data through wifi with FlashPAP or Sleep Master utilities.

Stick it to the man, Download OSCAR and take back control of your data!

Thanks Ian. Like I didn't have enough Honey-Do projects to tackle. Mornincoffee

RE: FlashAir Bandwidth Limitation
Another thing I have noticed about connectivity with the wifi card in a Resmed A10 machine is related to the power saving function with the machine. If the machine is full power ON (green light on top) the wifi card has stronger connectivity then when the machine is in power saving mode but technically ON (no light ON on top).
