MR6400 4G Network dropping frequently have to reboot again and again
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
I am using Indian Airtel 4G SIM card in my MR6400 model V4, with firmware version 1.10.0 0.9.1 v0001.0. I am facing frequent network drops. As long as I am using the internet, it works fine. However, when I keep it idle, the internet disconnets within 10-15 minutes. The only way to recover is to reboot. I have to keep rebooting the router again and again to restore the lost internet connection. I contacted the local customer support over telephone, they told me try different SIM cards and changed primary and secondary DNS to 8.8.8.8 and 8.8.4.4 respectively. Also changed channel width to 40Hz and channel to 11. None of these solutions have worked so far. I have also tried different permutations and combinations with Airtel APN profile settings. Nothing has worked. Rebooting seems to be the only solution.
Please help ASAP, as I need to do work from home and I am dependent on this connection.
@Sunshine thanks for the response.
I use my laptop and iphone on wifi to connect with the router. On the router - the power, wifi, internet and LTE signal strenght indicator lights are always on. I use internet for Zoom call or for browsing internet on my laptop and iphone.
Once I stop browsing, after say 15-30 mins, when I start using my laptop and iphone again, the wifi is connected but it shows no internet connection.
I am able to open the TP Link management page by accessing 192.168.1.1. Under the network it shows exclamation mark or a cross on the internet logo.
I am helpless at this point of time. All the lights on the router are still on, the signal strength is even 50%. Yet, it shows internet as either exclamation mark or cross (disconnected). When it shows cross, it displays message - "Please check your configuration".
At this point of time I reboot the laptop and the internet is back again! The cycle repeats when I again stop browsing for 15-30 mins. Following is flow chart:
Router booted -> Internet Connected -> Stays on till I am browsing / using internet in any form -> Stop using for 15-30 mins -> Internet drops (exclamation or cross), but LTE signal strength is 50%+ and all lights on! -> Reboot ->Internet connected again...repeat
I am using the another SIM card from the same company in my phone and it works seamlessly! Hotspot also works seamlessly.
