 I am flashing a modified version of the wifi scan sample onto my nrf7002dk. Most of the time, the firmware will run and return the expected results. Sometimes, I will get this error:

I have the same error message as Michael, but my Actual says 0x8888888. &lt;br /&gt;We have 3 7002DKs that I tried flashing shell example to, all of them getting the same error.&lt;br /&gt;When I first worked on the 7002DK, my desk had a router near it, and when it started getting the error, I showed it to my colleague in another room (that didn&amp;#39;t have a router), and it worked after resetting, so we decided it may be interference from the router.&lt;br /&gt;I can&amp;#39;t recall how often the error appeared, but from yesterday, it was everytime I flashed wifi code to the DKs.&lt;br /&gt;Rebooting the device did not help, I tried both --reset and --recover.&lt;br /&gt;I did receive a reply from simonr that I should manually set the MAC address to the OTP memory.. I will give it a shot today. iirc my code used to have a section where it manually sets the MAC address, which I am not doing now.&amp;nbsp;&lt;a href="https://devzone.nordicsemi.com/f/nordic-q-a/102054/wifi_nrf-library-boot_sig-check-failed"&gt;wifi_nrf library boot_sig check failed&lt;/a&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;I will give you an update sometime today or tomorrow!&lt;br /&gt;-Eric&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Wi-Fi Scan Sample causing error (Boot_sig check failed for RPU(0))</title><link>https://devzone.nordicsemi.com/thread/437471?ContentTypeID=1</link><pubDate>Thu, 20 Jul 2023 12:34:00 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:741c3e79-7899-4204-9eff-bca93fc529f4</guid><dc:creator>dejans</dc:creator><description>&lt;p&gt;Hi,&lt;br /&gt;&lt;br /&gt;Which nrf7002-dk board revision do you use?&lt;br /&gt;&lt;br /&gt;Best regards,&lt;br /&gt;Dejan&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Wi-Fi Scan Sample causing error (Boot_sig check failed for RPU(0))</title><link>https://devzone.nordicsemi.com/thread/437460?ContentTypeID=1</link><pubDate>Thu, 20 Jul 2023 11:58:35 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:b3c97e35-9eb1-46f7-818b-306fadafbb6f</guid><dc:creator>dejans</dc:creator><description>&lt;p&gt;Hi&amp;nbsp;&lt;a href="https://devzone.nordicsemi.com/members/libochengll"&gt;erichotterbeefcurry&lt;/a&gt;&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Could you please confirm that you see exactly the same error as Michael?&lt;br /&gt;&lt;br /&gt;Could you please provide more information about your environment?&amp;nbsp;&lt;br /&gt;&lt;br /&gt;You mentioned that you needed to move devices to another room for them to be able to work as expected.
