I think that I tried to use US firmware on my european wifi router, now the power led keeps flashing. I changed the IP address settings according to the instructions from the manual (see below), got a tftp progie and the right firmware. The issue is that it doesn't seem to upload anything. Any clue? Thanks in advance. The firmware upgrade failed, and/or the Power LED is flashing. The upgrade could have failed for a number of reasons. Follow these steps to upgrade the firmware and/or make the Power LED stop flashing: â€¢ If the firmware upgrade failed, use the TFTP program (it was downloaded along with the firmware). Open the pdf that was downloaded along with the firmware and TFTP program, and follow the pdfâ€™s instructions. â€¢ Set a static IP address on the PC; refer to â€œProblem #2, I need to set a static IP address.â€ Use the following IP address settings for the computer you are using: IP Address: 192.168.1.50 Subnet Mask: 255.255.255.0 Gateway: 192.168.1.1 â€¢ Perform the upgrade using the TFTP program or the Administration tab of the Routerâ€™s web-based utility.
