topic 5G EE w/Huawei CPE pro + Tenda mesh MW3, fails to connect to internet in Mobile Broadband https://community.ee.co.uk/t5/Mobile-Broadband/5G-EE-w-Huawei-CPE-pro-Tenda-mesh-MW3-fails-to-connect-to/m-p/1053685#M17377 I'm having an extremely strange issue only with my EE business sim  Sadly I don't possess the networking knowledge to understand how to troubleshoot it, and there are no similar scenarios I've researched to aid (besides these ones <A href="https://community.ee.co.uk/t5/Broadband-home-phone/Connection-to-Orbi-Mesh/td-p/893981" target="_self">https://community.ee.co.uk/t5/Broadband-home-phone/Connection-to-Orbi-Mesh/td-p/893981</A> & <A href="https://singletrackworld.com/forum/topic/it-networking-cluelessness-what-am-i-doing-wrong/" target="_blank" rel="noopener nofollow ugc">https://singletrackworld.com/forum/topic/it-networking-cluelessness-what-am-i-doing-wrong/</A>) Home mobile broadband setup summary:5G Network provider (EE [Main] - [Three & Vodafone to test issue]) --> Modem (Huawei 5G CPE Pro - H112-370) --> Mesh routers (Tenda MW3 3-pack) The problem:While using the EE network sim in the modem, the mesh router will not connect to the internet during setup or after with DHCP or bridge. (Three and Vodafone both work fine)While mesh routers are connected with EE, the Internet is still available by directly connecting to the Huawei modem via wifi or ethernet. The complication:Using the exact same settings on the Huawei modem and router while using a Vodafone or Three network sim. The mesh router instantly sets up correctly and connects to the internet. I don't understand this. It leads me to believe it's a problem directly with EE. Additional details:Huawei Modem: Unlocked, Not in bridge mode for the above tests, toggling bridge mode did not solve the problem.Mesh router: Setup using DHCP (other options are Static IP or PPPoE, but I have no idea how to set these up). Ethernet from Modem (Lan only port) connects to WAN/LAN port of mesh routerResets: I've additionally tested everything with clean resets for mesh routers and huawei modem with sim changes aswell. This has not affected the outcomeMore details can be provided The solution?: I have no idea. It must be EE? if all others work (Vodafone and Three). Can someone help me solve this?
