Region : India

Model : TL-MR3420

Hardware Version : V1

Firmware Version : 3.12.21 Build 120523 Rel.37880n

ISP : Reliance


Hi,

I've just set up a MR3420. It works fine in "WAN only" mode and provides access via our ADSL modem. It also works fine in "3G only" mode and provides access via a Reliance Netconnect+ USB modem (a Huawei E150 I think). I updated the firmware to the latest version in order to get it to work with the USB modem.

The problem I have is that when I set it to "3G preferred" it doesn't seem to connect over 3G. I can see it tries to connect but then fails and then WAN takes over. The connect and disconnect options are greyed out on the 3G page so I am unable to manually get it to retry. I've tried leaving it for a long time but it doesn't seem to connect over 3G ever. I've tried setting 3G to connect on demand and connect automatically but both behave the same.

Am I doing something wrong, or is this a software fault in the router?

Thanks

Is it possible that the 3G takes a long time to connect so that the router mistakenly judge that the connection failed, then it failovers to WAN?

I suspect that is what is happening - it does take a very long time to connect to 3G. I presume there is no way to set a longer timeout?

Sorry I'm not so sure whether there is any chance to change to a longer timeout or not, it seems there is no information about that on the router's web interface...Maybe we just cannot do that...
