• If you try to solve this problem, just don t buy the first OpenBCI WIFI shield you find on ebay like this one:

• We again want to honor these great demos of the WIFI shield developer A J Keller from Neurosity:

Testers wanted for the new denoised and power improved version of the OpenBCI WIFI shield

• on Aliexpress, WIFI shields can be found which are descibed as 8 channels WIFI denoised, it is a denoised and power improved version of the OpenBCI WIFI shield

• If you try to solve problems with packet loss and cyclic noise spiking, just don t buy the first OpenBCI WIFI shield you can find on ebay, like this one:

• it might be an old WIFI shield with packet loss and cyclic noise spiking.Buy a denoised and power improved version of the WIFI shield for your tests, which is sold on Aliexress:

• It seems that this problem is known to the developer of the power improved and denoised version of the OpenBCI WIFI shield

• Unfortunately, the labeling of the new power improved and denoised WIFI shield is not always clear, it is not clear which devices has this features.

• We suppose that there are still old WIFI shield sold with issues.

• It would be highly desirable, that the labeling of the WIFI shield on Aliexpess is better

• It should be absolutely clear, that testers buy the right WIFI shield to test and publish the results

• Everybody should know which new WIFI shield to buy and where, and which are the problems with packet loss and cyclic noise spiking, and how they can be solved

• It is a pitty that great testers eventually choose a WIFI shield that is brocken instead of a knew one which is described here
