Welcome to the Community!
Since you have been a long time customer I have organised a new TP link VR1600V to be sent to you.
This is the current modem that is shipped for your service.
If you need help setting up your modem click here
Please tell us how the performance of the modem is once you set it up.
The modem connects at about 50Mbps, but very slowly drops down in speed and after a week is at 38Mbps. Never seems to sync up in speed only down. if I disconnect and immediately reconnect it's back to 50Mbps again. So i thought I'd try enabling the auto-reboot function in the modem under system tools. It's set to 3 days to restart at 3am but this function does not work. Is there a firmware upgrade that fixes this?
I'm sorry to hear that, though I do recommend that the modem is switched off & on every once in a while, especially if the weather is hot.
We currently do not have new firmware upgrade to fix this but I can advise that you check this function directly for TP Link so they can investigate this as well.
We will also take this into account should there be any firmware update.
