I have an RUTX11 which has performed well for the last few years. Using a UK EE SIM, I routinely see 100Mbps+ download and 30 - 40 Mbps upload (according to Ookla SpeedTest).
However, since January 1st, whilst the download speed has remained at 100Mbps+, upload struggles to beat 5Mbps. Nothing has changed with respect to location, aerials etc. EE say nothing has changed from their perspective. The degradation is real as I've been unable to stream to Facebook.
The firmware in the RUTX11 was dated to 2020 so I updated it to the latest but this made no difference. My next step is a factory reset.
Are there any features of the router that will assist me in finding what the issue is?
