19.5v 4.74a Laptop power supply solved my problem with wa7210n always restarting when using 30m cable!!

I got myself an unbranded 19.5v 4.74a laptop charger for php980 from our local electronics shop. It worked now using 30m cable. Thanks to @Victor Ramos and @danymarc for the tip.

I found something. An old modem power adapter. It's 18v 500ma. Just might work. It turns out that this old power supply that I found is 18v AC. It was fir the zte zxdsl 831 modem. I wonder why it's...

Thank you Victor. I'll try to find 16v power supply first to test.

I learned from other thread, voltage should be increased if you want to use longer cable. So what voltage and current rating should be used? The power supply that comes with my wa7210n is 12.04V/1A

I have the same problem, using 30m cat6 cable, my ap keeps restarting. I tested my cable with a good cable tester and it shows my cable is good. There is no way to recrimp the rj45. Has anyone found...
