Dear All, I'm facing a strange situation in my admin page as my GL-XE300 can't send SMS from the Web portal. Anyway, it receives SMS very fine except the delay of something like 1 / 2 minute(s). Any advice ? Thanks ![image](https://forum-static.gl-inet.com/original/3X/0/4/04838d203cfb60097ed75c308898fa423aaadbc7.png) ---

This could be an issue with the modem firmware. Some older ones do have issues. Can you pls post the screenshot of the modem status page? ---

What do you mean by "Modem status page" ? I can't seem to find the modem firmware version anywhere in the Web portal or even in Luci โ˜น I sent the following AT command : AT+CGMR ... and got this result : **EP06ELAR03A08M4G** ---

Which version of your firmware is it? I remember the latest firmware fixed this problem, can you try it? [https://dl.gl-inet.com/router/xe300/](https://dl.gl-inet.com/router/xe300/) ---

Hello, I'm already on this firmware 4.3.17 (2024-06-20) and previously I was on the previous one 4.3.16 (2024-02-27). The EP06-E firmware I have, as said previously EP06ELAR03A08M4G and someone from support team on [Quectel forums](https://forums.quectel.com/t/ep06-e-and-em06-e-latest-firmwares-request/22129/70) sent me the latest version as per today which is : EP06ELAR03A20M4G Yet don't know how I am supposed to flash this firmware as it is a small Linux system with a non-x86 architecture.+ very small storage space. If I have to go on the firmware update path, I will have to open my GL-XE300C6 and take the mini-pcie modem to put it on a USB-to-MiniPCIe converter. Yet I prefer to wait for the feedback from someone here in order to be 100% sure I will not break anything as it seems that the firmware version downgrades are not that easy. ---

Just upgraded modem from : - PREVIOUS VERSION : EP06ELAR03A08M4G - LATEST VERSION : EP06ELAR04A22M4G Didn't restarted the GE-XE300C6 yet after the upgrade but for now, although the 3G/4G LED is on and blinking from time to time, modem is not answering to command "gl\_modem AT AT+QGMR". Should I POWER OFF the whole module and POWER it back ON again in order to see or am I running into a problem as my version was EP06ELAR0 **3**... and the one I upgraded it to is EP06ELAR0 **4**??? Thanks ---

There's a bug ```auto opkg list-installed|grep modem ``` Because I don't know your firmware version Can you check the commit of the current modem? I will compile an ipk and send it to you later ---
