Nighthawk M1 - Data offloading won't work
Nighthawk M1 LTE Mobile Router, latest firmware (of March 2018), latest Netgeat Mobile App installed. I'm trying to get the data offloading feature to work, with little success. Tested it with two s...
Thanks for the vote of confidence UK-based . It looks like you spotted the issue and answered it great :). HannuKop let us know if it works once you get the M1 gateway IP address moved away from the routers address ( I'd also make sure its outside the routers DHCP range too so no other device gets a conflicting IP with the M1).
The only other issue I can see that might crop up is if both the M1 and the router are running DHCP services, that could cause some confusion on the network. Do as UK-based says and correct the IP conflict and see if that works, if you get issues with other devices on your network I'd disable the DHCP service on the router . If the router has a dhcp relay setting I'd enable that to pass through any DHCP queries from the M1 to devices directly connected to the router. But if all your devices connect via the M1 the issue may never crop up, the issue may only appear if you have some devices connecting via th router and some via the M1
MicW: thanks for responding and filling in important details that I'd omitted - I knew I could rely on you :smileywink:.
This raises some questions in my own mind. If this is how the data offloading process is implemented in other devices, surely there will frequently be IP address clashes since the default gateway IP address of virtually all routers is either 192.168.1.1 or 192.168.1.254. It seems to me that there should be a more intelligent approach to data offloading. For example, when data offloading is set up in the mobile router, it should check the gateway address of the "wired" router and if there is a clash, offer the user an alternative address that it will "adopt", instead of its current address, warning the user that once changed, the new address will be needed to access it via a browser. At least this would be a lot more helpful to users who aren't that familiar with networking. There are probably even better approaches that haven't yet occurred to me - does anyone have other ideas on improving this process?
If you find that the DHCP address ranges on your M1 and the other router overlap but you want to keep DHCP active on both devices, you could change the ranges so that there's no overlap. I've got a landline-connected router and also the M1, which I bought because I only get 3Mbps on the landline - yes, you read that correctly! Both routers have DHCP enabled so that if the M1 goes down, I still have WiFi access. I've changed the ranges on both devices so that they don't overlap. You may find that it's only necessary to change the range on one device if the other has an unused block of addresses - you may only need a handful for your mobile devices.
- You make a valid point. As DHCP won't cross foreign routers and the M1 is just off loading to the primary router/modem the 2 DHCP services with non overlapping ranges will work for internet access . Trying access from devices attached to the M1 to a device attached to the primary router may be worth testing though. And I suspect if some devices are within range of both DHCP services may cause both to respond. Again probably not a issue on a small home network.
Actually ignore what I just said, I wasn't thinking. Since the router and M1 will have their own seperate wifi ssid you won't get both DHCP services responding. The data offloading should work fine simply set, each group having net access seperate from each other I suspect, I haven't tested any of this just a thought process
