Philadelphia's new municipal wifi network kind of sucks, but I'm trying to give it a shot. I'm about 450 feet down the street from a lightpole antenna for the network. There are leafy trees all down the street. When I hang my wireless router out my 2nd floor apartment window (WRT54G with dd-wrt) it can just pick up the signal, but weakly and intermittently. DD-wrt reports signal strength no better than about -72, and it changes constantly. So I'm trying to figure out...
- What kind of antenna should I use outside the window, or better yet, through the window? My WRT54G stock omni antennas with handmade reflectors barely pick up the signal. I tried using a prefab "Deluxe Cantenna" and it didn't help. I'm thinking that, because I'm trying to get signal around the trees, a directional antenna isn't the solution. From eBay I got really tall, supposed 9dbi replacement antennas for the WRT54G, and put on the reflectors, but that didn't have much effect either. I'm looking for a cost-effective solution - perhaps one of those Hawking corner antennas, to grab a focused swath of signal?
- An alternative is to go on the 3rd-floor roof rather than through the window. I'm not sure yet if I have roof access, but if I do I'm thinking a directional antenna might help because it'd be above the trees. So then there's the cabling issue. To keep the antenna cabling short, I guess I'd have to put my router on the roof as well (in a sealed plastic box?) and then run an ethernet cable down the outside wall and through a window. That would mean leaving a router on the roof, and a window slightly ajar, through an east coast winter. And providing power to the router! (Argh.) I don't think a USB-wifi-stick antenna will work - I want to run my home network (a couple desktop computers and Vonage) off the line, using an ethernet-fed second router. What's the right way to set it all up?
Thanks for your thoughts!
