This summer I wish to take my laptop outside and do some trading from the backyard. I was thinking of getting an 802.11b (Wi-Fi) wireless setup to attach to my cable modem. Has anyone tried something like this? Is the connection a solid one without interference? Will the data stream be clean? Is this feasible for some trading. I know this setup allows internet surfing, but I don't know how good, or error free, the connection is. Thanks.
