ERR_CONNECTION_TIMED_OUT in LTE5398-M904

VanKiller

Hello,

I have a problem with my LTE5398-M904 for 5 days with SIM Orange and good external antenna. I had no problems with it for several months previously. 50% of page opened/refreshed take a long time and finally end with: ERR_CONNECTION_TIMED_OUT or broken site. I have to refresh the page many times to open it in all devices (more than 10 - windows pc, android phones, android tv, linux pc) in network. Devices are connected to router directly via UTP, via switch or wirelessly. I haven't changed anything in the router configuration for a long time.

I tried:

• Manual band select
• Factory default
• Unplugging the router from the power supply for a long time
• Connect only one device to router
• Upgrade to V1.00(ABQV.5)C0 - currently i have V1.00(ABQV.4)C0, because on V.5 the router had the same problem and additionally from time to time it completely lost the internet
• Changing DNS in router
• Long ping-tests (1000 packets, 32 bytes, avg_time=22ms, 0% loss)
• Contact with internet provider

Nothing helps.

Cellular parameters:

SpeedTest: 90Mbps Down / 25Mbps Up / 25ms ping

My mobile phone is also in Orange and LTE connects to the same BTS and works perfectly. Laptop via phone hotspot works great.

Any idea how to find a solution?
