Nighthawk M6 Pro Slow Upload Speed

[jackings]

Hi there,

I have a M6 Pro (EU version), connected to a high gain external antena. I can get pretty good Download speeds (200Mbps plus) but upload doesn't seem to get any better than 8 Mbps.

I've plugged an older TPLink (MR550) to the same antenna with the same SIM, and have been able to get 120Mbps Down and 100Up (it doesn't have all the bands the M6 has), so the issue seems to be hardware or software related in the M6 Pro. In the first few hours of usage it did get up to about 100Mbps upload speed, but then it dropped and never really picked up (even after multiple reboots, connection checks).

MR6450-100EUS_NTGX65_12.01.54.00_Generic_02.05

Any help would be appreciated! Thanks

Country? Carrier? APN settings? MR6450 bought new or refurbished/used?

Country: Portugal

Yes, same SIM, same APN configuration in both tests (TP link mr550 vs M6 pro). M6 was bought new.

check with your portugal carrier if your m6 pro is a certified device to be used in their network, and explain your situation. bring the sim to your local carrier store and do a speed test so they see what you are talking about. from what you stated, everything you said is really all there is to do on the m6 pro. if you are not getting optimal performance, it could be a carrier issue.
