Gig slow speeds since last 2 days

I have started to get slow up and down speeds since last 2 days.  I cannot get over 600 down 20 down. I used to get 950+ down and 40+ up.

I use my router in modem mode with computer directly connected via cat5e ethernet cable and did not have any issues before.

There is a garbled  message about some issue I cannot make out when I call customer service - literally sounds like some one left the message from a low reception mobile line.

As usually customer service cannot find any issues.

 

Here are my stats. Can anyone see anything wrong?

2 of your upload streams are on the wrong modulation and the power levels are too high. I cannot comment on the download streams or network logs as you failed to add them 🙂

Re: Gig slow speeds since last 2 days

Thank you. Does this mean I need an engineer visit? It seems to be a bit better today. Could you advice on the below data?

Re: Gig slow speeds since last 2 days

You have quite a few Post RS Errors and still 2 upload streams on the wrong modulation.

Have you tried a full factory reset? Hold in the pinhole at the rear of the router for at least 50 seconds and then release (the lights will flash while holding in the pinhole reset button after about 10-15 seconds) then allow 5 minutes for the router to reboot and re-sync the connection.
Please ensure that your WiFi network password is still readable on the Hub sticker before you do this or that you at least have a copy of your original network password.

While in router mode run a test and see if you're getting the same results. Once finished you can put it back into modem mode and run another speed test 🙂

Re: Gig slow speeds since last 2 days

Yea, these logs were after full factory reset. i have booked an engineer visit. hopefully they will be able to fix it.

Thank you very much.
