I recently purchased a RUT951 Router, and I’m facing two issues with it.
When using the router with a fixed internet connection via WAN, the internet speed is very slow. I tried pinging 8.8.8.8, and after every 7-8 packets, the connection drops. After 4 retries, it reconnects. This issue is persistent, and I cannot use the router at all via WAN.
The second issue is that I cannot send SMS messages via AT commands. After sending the AT+CMGS command, I receive the “ERROR” message. However, SMS messages can be sent from the interface and through the send command using gsmctl.
I’ve tried both available firmware versions, RUT9M_R_00.07.12_WEBUI.bin and RUT9M_R_00.07.11.3_WEBUI.bin, and I experience the same problems with both.
Can I ask…
Do you look at cpu usage? Is high?
The 951 use Mediatek, MT7628, 580 MHz and is much better then the old 950 (Atheros Wasp, MIPS 74Kc, 550 MHz)
CPU load is a maximum of 70-80% when it is used intensively on GSM, and on LAN I have a maximum of 12%.
RAM usage is at 47%, and Flash is at 13%.
The internet interruption issue is only on WAN, I have no problems at all on the GSM side.
I tried using it as an access point both with a router using PPPoE and with a router using a fixed IP, and I encounter the same issue. I cannot connect it directly to the internet from the ISP because the connection is through fiber optic.
I don’t use any type of firewall or other settings. I am using it exactly as it came, with the default factory settings.
AND… RUT are in default settings.
WAN as DHCP (not PPPoE)
LAN at 192.168.1.1
Just double checking… look at the wan status… look the ip address of the wan?
Are you getting? please… cannot be something like 192.168.1.xx, same network at lan.
This was the issue: I had the same IP class on both routers, and I’m not sure why I didn’t think to check that.
Currently, I have the following configuration, and it’s working: IPS <192.168.1.0/24> RUT <192.168.2.0/24>Laptop
Could you assist me in resolving the SMS sending part via AT commands?
Thank you for your support !
The command to send an SMS via AT is as follows: AT+CMGS=
I give the following commands:
gsmctl -A AT → response OK
gsmctl -A AT+CMGF=1 → response OK
gsmctl -A AT+CMGS=“+1234XXXXXX” returns ERROR and doesn’t show “>”
If I execute the command in this format (gsmctl -A “AT+CMGS=”+1234XXXXXX""), the “>” sign appears, but after I write the message and press CTRL-Z, the process goes into the background and stays there without anything happening.
I’ve tried without the prefix and it still doesn’t work.
I’ve also tried what is presented here: serial port - AT+CMGS returns ERROR - Stack Overflow
I am connected via SSH to the RUT951 and sending the commands from there, I don’t see the router on the COM port.
I want to replace the old solution that works with a USB GSM modem with the RUT951.
I believe there is an issue with the gsmctl command, which doesn’t work correctly with AT+CMGS. gsmctl -S -s, NUMBER TEXT
This command works, but I would prefer to stick with the AT commands so I don’t have to modify the alarm solution too much. I want to use it for multiple projects.
I also tried the method presented on the website https://wiki.teltonika-networks.com/view/Gsmctl_commands.
After sending the command gsmctl -A ‘AT+CMGS=“+1234XXXXXX”’, the GSM modem gets stuck, and I have to restart the router to use it again. root@RUT951:~# gsmctl -A AT [handle_requests:429] error: Failed to handle AT exec. ERR: Request timed out
