Okay, here is the scenario:
Travelling in an RV with desktop (no wireless card), a laptop (wireless card), and have available a Linksys WRT54G Router. I am staying at an RV park that is offering WiFi, but the signal is quite weak (1-2 bars, if any). The access point is about 150ft or so from the RV. The line of sight when inside the RV is none (go through about 2-3 other RVs), but from the roof of the RV I can get a fair signal (4 bars) and I do have a line of sight. I don't have much information on the Park's equipment, as they have not been willing to share it or assist in getting this set up properly.
What are my options to be able to get both the desktop and laptop connected to the access point, as well as possibly use the router for an added layer of security? I have looked into the various antenna and even bridging, but am a little perplexed as to what would be the 'best' solution for this scenario. I thought possible a roof antenna or a different antenna on the router and use it as a bridge with the desktop PC. Would this be possible?
