Updated to latest FW for my RT-AC88u.. I should not done this. Because after update my AP (RT-n66u) stopped working. Repeatermode on RT-AC88u is not compatible with the 380 FW on my RT-n66u. What is best to do??? Wait for new FW for my 66u, or roll back to 380 FW for my 88u??? Or is it any other fix??
