Read much slower than Write on ReadyNAS 516.
Running NAS Performance Tester Vers 1.7 on default setting (400MB with 5 loops) from my WIN 7 64bit PC over wireless gives these very slow results. Ave Write in MBps 5.65, 4.22, 5.33 and 4.46. Ave R...
Your old router will not have more signal strength than the new one. The maximum transmit power is regulated by country (and in your case is 100 mw). The old router might have less power, but it will not have more.
Powerline is an option - it can be hit or miss (depending on your power circuits), and (like wifi) your throughput is always much less than the link speed. However, in many situations it works well. Get at least AV500. A WiFi extender is another possibility - especially if it enables 5 ghz, which is much less crowded.
On the read/write question - anything you write can be queued up at every step in the network path. That means in Windows, your USB adapter, the router,and the NAS. The NAS itself can do read-ahead when you are doing the read test, but it cannot send any data until the read request reaches it. So the queuing is asymmetric, and favors the write path in cases where the wifi network is misbehaving.
FWIW, as far as the NAS is concerned the writes take longer (since the raid parity blocks need to be rewritten).
