then i should have uhd 3.9LTS both in the host and the e312? because i've been using GNU-Radio 3.8 with UHD 4.3.

The E312 isn't like other network-connected or even USB-connected USRPs.

The intended use is as an embedded platform--it's a dual-core ARM system with a USRP radio as an internal peripheral.

The "network mode" was only ever intended for initial "sanity checks", and even then, only at very-low sample rates
  (100-200kSPS to the host).

The usage model is that you develop code that runs natively on the ARM, and perhaps offloads some work to the
  FPGA via the RFNoC architecture.

But if you really do want network mode, my understanding is that you have to stick with a UHD 3.9 environment.

i apologize if i make basics questions, im new using GNU-Radio and the e312

You should probably read this:

https://files.ettus.com/manual/page_usrp_e3xx.html#e31x_migration

In particular, network mode is no longer supported on E3xx after the MPM
migration and UHD 3.15
