Philadelphia's new municipal wifi network kind of sucks, but I'm trying\nto give it a shot. I'm about 450 feet down the street from a lightpole\nantenna for the network. There are leafy trees all down the street. When\nI hang my wireless router out my 2nd floor apartment window (WRT54G with\ndd-wrt) it can just pick up the signal, but weakly and intermittently.\nDD-wrt reports signal strength no better than about -72, and it changes\nconstantly. So I'm trying to figure out...\n\n1. What kind of antenna should I use outside the window, or better yet,\nthrough the window? My WRT54G stock omni antennas with handmade\nreflectors barely pick up the signal. I tried using a prefab "Deluxe\nCantenna" and it didn't help. I'm thinking that, because I'm trying to\nget signal around the trees, a directional antenna isn't the solution.\nFrom eBay I got really tall, supposed 9dbi replacement antennas for the\nWRT54G, and put on the reflectors, but that didn't have much effect\neither. I'm looking for a cost-effective solution - perhaps one of those\nHawking corner antennas, to grab a focused swath of signal?\n\n2. An alternative is to go on the 3rd-floor roof rather than through\nthe window. I'm not sure yet if I have roof access, but if I do I'm\nthinking a directional antenna might help because it'd be above the\ntrees. So then there's the cabling issue. To keep the antenna cabling\nshort, I guess I'd have to put my router on the roof as well (in a\nsealed plastic box?) and then run an ethernet cable down the outside\nwall and through a window. That would mean leaving a router on the roof,\nand a window slightly ajar, through an east coast winter. And providing\npower to the router! (Argh.) I don't think a USB-wifi-stick antenna will\nwork - I want to run my home network (a couple desktop computers and\nVonage) off the line, using an ethernet-fed second router. What's the\nright way to set it all up?\n\nThanks for your thoughts!
