Wifi seems ok and merline might flash. Never thought of an AP as my second N55U seems to have a wifi problem with my amazon echos not being able to keep connected. Dont if that is the router wifi, it came with non standard antenna, or the amazon echos themselves. Just as I was typing this the 3rd N55U has lost wifi connection.
Seems TTB were having problems earlier so when it has all settled down, they decided to upgrade edge routers tonight at 1AM and I lost connection I will re-test the old router.
