tl-mr3420 not switching back automatically from USB to WAN, setting is WAN preferred with usb fail over
Model : TL-MR3420
Hardware Version : Not Clear
Firmware Version :
ISP : bsnl wimax[/COLOR]
My BSNL WiMax on WAN is preferred connection while 3g dongle on usb is the backup connection.
Once preferred connection gets lost, it switches over automatically to usb dongle. But when BSNL wimax gets back, it does not switch back to WAN until i soft reboot it from web management tool of the router.
H/W version is 3.0 and has been upgraded with latest available firmware.
Any Solution is highly appreciated
