About a week back upgraded from M100 to M350 package. With old package used to get speed of 90-110 on most of devices (fast.com). I did not move any thing hub, devices all in same place and speed gone down to 28-80 (speed gone down and variability has increased). Have reset (pen/ pin reset) rebooted device nothing works.
Are you using the same Hub or did they give you another one?
If you connect a computer/laptop to the Hub by an ethernet cable (just to test) - what speeds do you get.
You could try the pinhole reset again as it can be tricky - do it this way...
With the Hub switched "on", disconnect any ethernet connections (leave the co-ax connected) and then push in the “reset pin” with the end of a paperclip/thin nail/SIM tray “tool” or similar (bigger items like ball point pen ends may not press it in far enough) until you feel it at the “stop point” and hold it there firmly for a "timed" minimum of 60 seconds do NOT manually restart the Hub at any time.
Leave it 10' or so to stabilise and then your passwords/passphrase for both the Hub settings and the Wifi networks will revert to the two printed on the Hub sticker on its base/side/card. Make sure you use the wifi one for devices connecting to the wifi and the settings/admin one to access the Hub
See if that sorts it.
