Hi,

I've bought a 4G router but I'm having an issue where it seems to go to sleep / in to standby almost immediatley and will not wake up.

It is a TP-Link TL-MR6400 300Mbps Wireless N 4G LTE Router.
The Sim I'm using is a TPO "The Peoples Operator" 10GB Pay Monthly which is a customer network on Three.

The router and sim are brand new. I've registered the sim and run through the set up on the router. Upon booting it shows the internet status as "Connected" and I can confirm that
it is. The clients are getting about 27mbps up and 5mbps down so perfectly happy with that.

The issue is that within 2 - 5 mins of booting the router the internet connectivity drops. The router status page displays as "Connected" still but non of the clients have connectivity, pings don't work etc tracert stops at the gateway 192.168.1.1 This happens regardless of whether the connection is inactive or under use constantly since the router was booted.

If I reboot the router then I regain connectivity, but again only for 2 - 5 mins before it drops again.

I've done factory resets and re run through the set up more than once.

I've updated the firmware from v1.0.15 which it came with to v1.0.17.

I'm not sure if this behaviour is caused by the router or the sim but at the moment I don't have spares of either to try.

Does anyone have any ideas?
Thanks
 
I’m think I’m recalling this from memory but is there a “Connect on Demand” setting on the router? Perhaps disable that.
 
From a quick google it appears that other TP Link routers do have that option, but I don't seem to have it. Certainly not on the same screens as the screenshots I've found, but I can't see it anywhere else either.

This is the log from start up to loss of connectivity:

Its the Sim, checked on another and the router is fine. TPO confirmed on chat that they don't allow tethering on their network.
