Revision to WiFi disconnections and AJAX timeout errors
== Troubleshooting == | |
- | * Make sure you are running the latest stable versions of the main firmware (e.g. DuetWiFiFirmware), the WiFi module firmware (DuetWiFiServer), and DuetWebControl. You can find the latest files at https://github.com/dc42/RepRapFirmware/releases. In particular, Duet WiFiServer 1.19.2 (which requires DuetWiFiFirmware 1.19.2 too) and later versions try harder than earlier versions to reconnect to your access point if the WiFi connection is lost. You can check which versions you are running on the Settings/General tab of Duet Web Control. |

* If an AJAX Error is reported, check the Error Reason given at the bottom of the error message box. If it is anything other than Timeout, this indicates mismatched versions of Duet Web Control, or possibly a bug. If you are running the current stable firmware versions, or later beta versions, report the problem on the forum. | |
* Run M122 from either the web interface (if you can reconnect) or from USB. In the Network diagnostics, check the '''WiFi signal strength''', also called '''RSSI'''. Values in the range -30 to -50 are good, -50 to -60 is OK, -60 to -70 is marginal. Anything below -70 is weak and likely be unreliable. See below for how to improve RSSI. |
