fyi, i just bought another good quality cat6 cable with 10meter length..but ap still keep restarting..it possible my ap manufactured defect?

i dont know why my post state "Region : Argentina" and "Model : TL-WA901ND"..im not from argentina and im used tp-link TL-WA7210N

Hello fadyl87,

did you manage to solve your issue?

I'm facing same problem with mine. Using 30m cable cat5e Ftp, the antenna keep restarting, while using 3mt cable it work perfectly.

Thanks

Get another brand of cable with good quality to test.

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 an answer? By the way, my ap works using a 22m cable.

Is it possible to change another power adapter? It's a power issue and the adapter should be inside the list of suspect.

all problem should a loss power the original power supply...

I Have many problems with 5210, 7210, 7510 devices, fix change the power supply for other big in amperes and voltage, see and read this post http://forum.tp-link.com/showthread.php?85315-Problem-with-WA-7510N-and-signal-from-WISP

Have some 5210 with 38 meters the cat5E cable and PoE no problem a big power supply solved my problems...

but no discard manufactured troubles in the device...

regards...

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

dear @Alden...

remark: fix change the power supply for other big in amperes and voltage, see and read this post http://forum.tp-link.com/showthread.php?85315-Problem-with-WA-7510N-and-signal-from-WISP

for the 7210n the board is same to the 7510, you should connect a power supply no more to 20Vdc, is the maximun input voltage at the internal voltaje regulator.. amperes is 500mA to 1A...

regards

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

Don't be afraid, from 12 to 16 it's a small change, go 20v that way you only buy once
Make sure amperes are 500mA to 1A..
