Model: Archer MR550  
Hardware Version: V1
Firmware Version: 1.5.0 0.9.1 v0001.0 Build 230625 Rel.65051n

Hello,


I work for a company were we make our own mobile network. I tried to use one of our SIM with the Archer MR550 and had trouble to access the internet.
After investigation on our network, we found it seems to be because the router does not take into account the ICMP fragmentation request we send back to it to change its MTU.
If I manually set the MTU on my computer I can successfully access the internet through the router with our SIM.

 

Here is a Wireshark screenshot showing the fragmentation request our network send back to the router:

Is there anything that can be done for this issue?

Thanks
