I haven't stayed there yet, but I've heard that every room has it's own router. If you're having issues, finding the router and resetting it might help. Edit: I've also heard some try their bringing own routers, making sure that the router's antenna was screwed in properly, or buying an extended range antenna and swapping out the antenna. I don't know if these things actually work or not, though.
Please don't. If you have access to an access point (it's not really a router), and you reset it, you are interrupting other people's Internet access. If the Antenna is not properly tightened then yes you can tighten that clockwise to the connector. A personal access point does nothing with house wireless, but if your wired network is still working you can try to configure it to that. I used to do that before WDW had wireless. But a good network is going to block those for a good reason - you do not want a DHCP server added to your network, it can screw up service for everyone. Please don't change the antenna either. That only has to do with range and power level over the air. If you are lucky enough to have an access point in your room you already have the strongest signal. It's the person 2 doors away that is suffering. Your access point was engineered with the antenna that came with it and changing it can alter the reception for everyone.
You are using a different network. The rooms are served by one vendor and the common areas of the resort and parks are served by AT&T.

Yup I know. That's why I go to the pool; the AT&T service is usually better during morning and evening loaded hours but not always. I know a lot about wireless network engineering and I once mapped service at The Beach Club. I found that they had poor engineering, with improper spacing of the channels assigned to the access points and overlapping channels between the common area SSID and the hotel room SSID. That causes interference and where there is interference nobody gets good performance.
If you get a lot of disconnect/reconnect events for the Wireless network, and the signal strength is medium or stronger, put in a report about that. It can be fixed.
If you simply get slow performance or problems with applications, but stay connected, that's probably overloading and nothing to be done but try switching to common area or wait until later and less loaded conditions.
If your signal strength is weak, in your room, put in a report. it won't likely get fixed during your stay but you might help out others in the future.
Installing a Wifi finder with signal strength monitoring can help because you can see how small movements, like going near a window or a different side of your room, might help you.
