Slow Download Speed on M350

Hi. I wonder if someone can shed any light on some slow speeds I am having. Been getting a solid 350MB for ages. Then yesterday I noticed some slow down, speed tests have been putting my connection at about 10MB down (still the full 35MB up though).

I have isolated all the devices from my nextwork, rebooted the router, reset the router, even went into modem mode with one laptop connected, still the same slow speeds. The call center say everything is fine their end and its my home network?? Can anyone help? I need to be able to work from home!

Re: Slow Download Speed on M350

All the stats look in order. Can you try the reset again as it can be tricky and the VM website instructions are "wrong" - do it this way.

With the Hub switched "on", disconnect any ethernet connections 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 (it is a six digit numeric one).

See if that sorts it first.
