I know this is an old thread, but maybe my trick can help others. I purchased a small portable router. It's a TP-Link MR3040 ($40-$50 on eBay), with a USB port, CAT5 port, and internal battery. It is about the size of a cigarette pack and has multiple configuration options. My primary use is to plug my Verizon Wireless 4G dongle into the USB port and have a portable wireless network in places where I don't want to connect to the public network, or at the hangar for a last-minute wx update for the iFly. But the neat thing about this router is that it can also get its internet connection through the CAT5 port. So while most hotel wireless networks are weak and Christmas slow, the rooms usually have a CAT5 cable connection that is much faster. I connect the router to the hotel CAT5 and my wireless signal is strong, secure, private, and several Mb faster than the hotel's wireless. So now my devices that don't have a CAT5 port (iFly, iPhone, tablet, etc.) can share the CAT5 speed. Each device still has to authenticate with the hotel's splash screen, but once connected the speed is terrific. I too struggle at times getting the 720 authenticated, but at least it connects to the same network each time instead of adding to the "PRE" list of wifi networks. With the router's small size, it can fit in a shirt pocket or flight bag. The battery lasts for hours and is charged through a seperate mini-USB cable, even while in use. I hope this helps someone.
