I just signed up a new account months ago and got two units of WA8021V5 (One included in the package, and top up for another node).

It perform much worst than my previous EC230. Weak antenna (2dbi only), slow throughput between nodes, frequent disconnection, and inconsistent router node switching.

If you are considering to get this model, my advice is don't. Even their "wifi expert" also admitted that this model is memang limited in term of performance.
