[srslte-users] Internet Connectivity Extremely Slow

Hey Bennett,

This is very weird. The eNB is sending the SN=5, but it is not receiving
the ACK from the UE.

Could you send the enb logs in DEBUG level again, but this time, could you
also include the respective enb.pcap (you can enable it via the enb.conf
file).

Kind Regards,
Francisco
