Nighthawk M2 IP PassThrough stops working when idle

So I have a Nighthawk M2 in IP PassThrough with a VPN tunnel uplink over time it disconnects from 4G network for some reason and as soon as I login to the Nighthawk it springs to life.

firmware NTG24_10.19.03.00

 

So anyone else having this problem? the ISP is o2

  • I would assume by spring to life, you mean it regains connectivity to the cell tower? Do you use it with a battery? Do you take it mobile or purely stationary connected to a wall charger?

    There could be a few things going on here.

    -o2 could be disconnecting you after being connected to their network for a while. ATT in the US seems to be doing this.

    -if you are using a battery with your M2 and not taking it mobile, i would suggest using it on pure AC power using the charging brick and no battery. your device seems to be going into some sort of sleep mode, which is really not described in the manual. how is your VPN set up?

      Thanks for the replies so far

       

      Yes its always plugged in I don't see how removing the battery would help I have a VPN from Zyxel VPN300 that the Nighthawk is connected to which connects back to my virgin media Zyxel FLEX200 with pings going down the tunnel and I can see the tunnel drop I have tied a Connection Keeper app but does not come back to life until I login with password to Nighthawk then it starts working.

       

      So its like this o2 gives out a 10. IP all works fine then 4G goes down Zyxel VPN300 picks up a IP of the LAN by Nighthawk I have set 192.168.7.0/24 I go to 192.168.7.1 login then it springs to life get 10. IP.

       

      You might be right it might be o2 I was just hoping it might be a firmware bug.

       

      So I have put the Nighthawk out of IP PassThrough mode and see what happens can take about 3 days uptime.

       

      What I need is a app that can auto login to Nighthawk so that it stays up any ideas?

      Well its been a week and no disconnects when out of  IP PassThrough so its not o2 and must be a netgear when in IP PassThrough mode.

       

      sad😞

        I have an M6 in IP Passthrough mode. I don't even remember the last time I rebooted it. obviously they are different devices. could be a firmware implementation difference.

      Yup tried without the battery in IP PassThrough still disconnects from 4G after a number of days so Netgear has broken uptime for IP PassThrough.😔

        so just to recap, the IP passthrough was working fine before the latest FW update happened? If that's the case, please submit a bug report for netgear may be able to address it in a future update

  • So its odd I had it in router mode for some weeks then just out of interest put it back in  IP PassThrough and for many weeks its been fine?
