Kicked off wireless network every time I click

[mustang303]

I am temporarly living at a hotel they offer high speed wireless internet, I have a desktop pc with a linksys instant wireless b pci adapter installed, I am able to access their network although every time I click to do anything I loose my connection and have to wait for my pc to pick up the network again, this is really frustrating, I have tried moving my pc all around to see if it improves, unfortunatly no luck, I also have a linksys wireless g broadband router model WRT54G is there a way to take advantage of my router here to improve performance? I have tried hooking up the router it shows up as an avaliable wireless network, although after I click to connect it shows the strength is excellent, but it is not picking up the hotels network. I have tried everything I can think of to no avail. any suggestions? Thanks everyone.
