The Asus WL-330NUL is even tinier than TP-Link’s diminutive TL-MR3040. In fact, it’s smaller than some USB thumb drives I’ve used. Its size and weight will tempt anyone who insists on traveling light. My advice: Resist that temptation.
The WL-330NUL is a very simple device. There’s a USB 2.0 connector on a stubby cable at one end, and an RJ-45 ethernet port on the other. Inside is an 802.11b/g/n chipset that supports one 150Mbps spatial stream on the 2.4GHz frequency band. It has no other USB port, so it can’t share files on an attached USB storage device, nor can it support a cellular USB modem.
The router left the factory with the preassigned password “Test1234.” Seriously?
You can operate the WL-330NUL in one of four modes: If you provide a USB power adapter, it can perform as a wireless router when connected to a DSL or cable modem or another hardwired Internet connection (such as you might use in a hotel or convention center), or as a wireless router when connected to a WISP (Wireless Internet Service Provider). While drawing power from a laptop, it can perform as a wired or wireless USB ethernet adapter for an MacBook Air or any other model that doesn’t have an ethernet adapter of its own.
