I have an M500 broadband package and the download speeds are completely fine but the upload speeds hover at between 1.3 and 1.6Mbps when connected directly to the router with a cable. The problem has got worse recently and is creating serious issues when conducting work calls over Teams. Does anyone have any suggestions on how to increase upload speeds as all the diagnostic tools return no issue and a reboot of the router makes no difference?
Many thanks

Thanks John
Ok, so yesterday morning (mainly out of frustration!) I removed a 10dB attenuator from the co-axial connection to the back of the router as I thought it may be causing a restricted signal. I have just re-introduced the attenuator and the Downstream status now looks as below. The performance issue is the same, with or without the attenuator in place. I notice that the Power is now all <~3.5dB though, is this too low?
