The R52s are worth the $113/pound of freight FedEx will charge you for the first pound of a shipment from Latvia to the US. 10 pounds worth of R52s are an even better buy!

The SR2 is in AP Bridge mode and everytime you reboot, loose power or apply a new setting the clients rarely reassociate without diabling and renabling the wireless interface several times.

Shouldn't they be more or less the same?
