Question : Access Point or Bridge?

I have my wireless router in the basement of my home and I have a few PCs wired into it. I however have my laptop roaming all over the house. The signal isnt the greatest on the 2nd floor. Id like to get a better signal.

I also purchased a BLU-RAY player that has network access but I dont have any wired connections around the house so Im trying to extend my wireless connection to have a RJ45 connection for the BLU-RAY player.

What would be the best option to do?

For an AP, it depends what your needs are... if you have only 802.11g equipment now, the least expensive option would be an 2.4GHz only AP like the (discontinued) DWL-G700AP (~$50 at amazon or newegg). If you want to upgrade to 802.11n it will cost a little more (I do not recommend this level, though your existing router might fit this category); 802.11n dual band will be more (note that if the description does not say "simultaneous dual band" it will likely work on only 1 band at a time because of power supply limitations); 802.11n simultaneous dual band (2.4GHz and 5GHz) will be the most expensive.
