MR600 v2 very slow data download over 4G+
Hello,
Asking for some help to diagnose very slow download over 4G+. I recently replaced a D-link DWR-921 with the MR600 and I'm getting much slower download speeds. I have reasonable signal strength on -88dBm, and would appear to have carrier aggregation on Bands 1 & 3. I have Bands 1, 3 & 5 available from my tower. (850, 1800, 2100MHz).
I haven't been able to get more than 12Mbps download reported using the routers own speed test, and Ookla Speedtest on a tablet. The DWR-921 had much faster download speeds located physically in exactly the same spot, and used to report the same signal strength at around 72-85%. I do not have external antennas on either router. I have Band selection set to 'Auto'.
Hoping someone can suggest other settings to check?
Thank you.
