Get error invalid serial number.
If you bought a set of routers, please kindly register the product with the SN on the box, instead of the individual router.
I use the SN written on a piece of paper that came inside the box which is slightly differrent to the ones on the idividual boxes but this still does not work.
please ignore my previous message, tried again the SN in the paper that came in the box and it worked.
Great, thank you for the udpate.
