 ===== Upgrade the uqmi package =====
-Download the custom **uqmi** packages for OpenWRT 22.03.2 here: **[[https://github.com/mrhaav/openwrt/raw/master/22.03.2/uqmi_2022-11-29-0.10_mipsel_24kc.ipk|uqmi_2022-11-29-0.10_mipsel_24kc.ipk]]**.
+Using the stock **uqmi** package provided by OpenWRT 22.03.2 I was not able to bring up the LTE interface. The error message shown by **logread** was:
+<code>
+daemon.notice netifd: lte4g (2329): Command failed:
+    ubus call network.interface notify_proto
+    { "action": 0, "link-up": false, "keep": false, "interface": "lte4g" }

 The **uqmi** depends upon **libubox** and **libblobmsg-json**, these are the exact versions that satisfied the dependency in my installation:

+Now the ''logread'' output is OK, except that IPv6 is not negotiated (may be a fault by the Iliad provider):

 ===== Configure the LTE connection =====

 I was not able to instal the **wakeonlan** package because it depends upon Perl (not enough space on flash memory). Fortunately I was able to install **etherwake**, which requires only **4 kb**.
+===== Upgrade to OpenWRT 22.05.0 =====
+To upgrade from OpenWRT **22.03.3** to **22.05.0** we used the **sysupgrade** option, which preserves the existing configuration, at least partially.
+Download the new firmware **[[https://downloads.openwrt.org/releases/23.05.0/targets/ramips/mt76x8/openwrt-23.05.0-ramips-mt76x8-tplink_tl-mr6400-v5-squashfs-sysupgrade.bin|openwrt-23.05.0-ramips-mt76x8-tplink_tl-mr6400-v5-squashfs-sysupgrade.bin]]** to your PC. Connect the PC to one of the Ethernet ports of the router and point your browser to the LuCI web interface. Click the **System** => **Backup / Flash Firmware** page and then upload the firmware file to the router by clicking **Flash new firmware image**.
+Once the router reboots, you can access it via SSH or LuCI web, the network configuration should have been preserved.
+Beware that all the extra packages must be installed again, notably the **uqmi** package, required to drive the LTE modem for internet access, must be upgraded to version **[[https://raw.githubusercontent.com/mrhaav/openwrt/master/23.05.0/uqmi_2022-11-29-0.11_mipsel_24kc.ipk|uqmi_2022-11-29-0.11_mipsel_24kc.ipk]]**. That version is not included into the official repository and thus must be downloaded from the GitHub repository.
+The repository roots are:
+  * https://downloads.openwrt.org/releases/23.05.0/targets/ramips/mt76x8/
