No, most WiFi equipment these days does not have a briding mode [at least not in the shipped versions.] Some of the more stable and reliable bridges that have been on the market for years are quite restricted as to which systems they will connect to -- sometimes only to the exact same model, sometimes only to devices by the same manufacturer.
Wireless bridges that follow a standard and so should interoperate [in theory] use 'WDS', "Wireless Distribution Standard". If a device you are examining does not advertise WDS, then it isn't the right one for you [short of replacing the firmware]; if the devices you want to connect to are not WDS, then you might not be able to connect to them from anything other than a device made by the same manufacturer.
:to act as an ethernet :converter, connecting to different brand APs (one at a time, of course). :Would like to buy only 1 bridge and have it work with other brands of APs. An :external antenna connector would be a plus.

I have no particular models to suggest at the moment, just general comments:
1) Read the reviews in places like pcmag and tomsnetworking and amazon . When I was last looking around a few weeks ago, it was quite discouraging: the top-rated consumer-level 802.11g devices were at 6 out of 10 or less in customer satisfaction. Mass sales is no guarantee of quality.
2) Read the reviews again, and read the informal reports in places like alt.internet.wireless and dslreports.com, this time with a view to what customers are saying about their support experiences with the companies. -My- quick summary, looking at those reports, would be
"If one of the devices works for you in -your- circumstances, then Great! -- but that doesn't mean it will work for everyone. If you are having a problem with it, and it is from any of the well-known commodity WiFi manufacturers, chances are that you will be disenchanted by the support organization, with a significant chance that you will end up swearingly up and down that you will never EVER buy from that manufacturer again."
Or to put things another way: If it works for you, then it works for you; if it doesn't work for you, then be prepared to throw it out (or sell it on eBay). You seldom get serious support attention from a WiFi manufacturer unless you have paid several times the going commodity-device price.
