Stephen/Owen -
You reported some pretty amazing results using a directional antennae with 802.11g 6 months or more ago. I'm trying to solve a problem for my mother-in-law (pressure is ON) where she formerly picked up her network via 802.11g from her son's house about 100ft from hers. A few weeks ago something changed abruptly and the apparent signal at her house (in the window facing the window his router is in) dropped from marginal to abysmal... basically she can no longer get network from the wireless from inside her house. I'm looking at the possibility of repeaters and of external antenna(e), etc. I haven't seen the router, it was provided by Qwest and doesn't sound like a Linksys from her description. They've done some channel hopping on the off chance it was just interference, with no results. Both houses may be "well shielded"... he is an architect/builder and I'm pretty sure used reflective-foil fiberglass insulation in his walls and he clad her entire house in corrugated steel. This is why I wasn't surprised before when she had to go to a window in her house to get his signal. Actually I was surprised she got anything at all. These two psuedo-faraday-cage houses are why I imagined a repeater (in her window) and possibly a directional antennae (in his window) would likely do the trick. Any thoughts/ideas/observations? As much as I like to experiment, I don't like doing it in front of my in-laws (I'm probably about to find out they are subscribers to this list!) - Steve |
i have set up a wireless bridge in the past between offices that worked very
well. a couple of inexpensive linksys bridge boxes and a couple of directional antennae which i mounted outside. the whole setup cost maybe $200-300 which was a lot less than burying a cable. don't know if an exterior installation is an option for you, but if you have line of sight through a window, it would probably work. all the best, lanny goodman albuquerque On 1/27/08 10:38 AM, "Steve Smith" <sasmyth at swcp.com> wrote: > Stephen/Owen - > > You reported some pretty amazing results using a directional antennae > with 802.11g 6 months or more ago. > > I'm trying to solve a problem for my mother-in-law (pressure is ON) > where she formerly picked up her network via 802.11g from her son's > house about 100ft from hers. > > A few weeks ago something changed abruptly and the apparent signal at > her house (in the window facing the window his router is in) dropped > from marginal to abysmal... basically she can no longer get network > from the wireless from inside her house. > > I'm looking at the possibility of repeaters and of external antenna(e), > etc. I haven't seen the router, it was provided by Qwest and doesn't > sound like a Linksys from her description.

Steve,
You might look at http://www.binarywolf.com/249/pringles_cantenna.htm for inspiration. They have a lot of different point-to-point d.i.y. solutions. Alternatively, you could just go get two Linksys Wireless- G Access Points, WAP54G, and the High Gain Antennae kit (worked at my house and was under $200 for everything.) Then simply bridge the two access points. The access points are worth using regardless of the antenna solution since they have decent gain, support WPA encryption, and have the correct antenna connector for any of the d.i.y. solutions.

The little plug-in-the-wall Airports do repeater duty, I think, and
aren't that pricey. The big Airport Extremes are pricey but have a spot for external antenna, have a signal-strength knob (don't watch the food cook) and can also be used as a repeater. Much easier (IMHO) to set up than the Linksys, though I haven't needed try to do the repeater thing. Does she have a new portable phone or other RF source and is she really using g? You might also have a freeloader in the neighborhood that is competing. I've had situations where performance was bad, so I put in MAC address security and things got dramatically better. Sometimes just moving the antenna over a few inches or mounting it higher up on a wall can make a big difference. C. Marcus G.

Hi Steve. Stephen and I and a few others were looking into building a
"community wireless network" .. basically a way to lash together several users sharing a T1 or similar broadband wired access. This is pretty sophisticated stuff, with Power Over Ethernet (POE), antennas, outside utility boxes with wireless routers and so on. This is different than simply extending the range of a wireless base station, which is likely what you'd find workable. I've not used a repeater, but as I understand it, most wireless base stations can be configured to be an intermediate bridge between a client and a base station. The airport express is a small "wall wart" that does this rather nicely. Google "Wireless repeater" for lots of hints. As mentioned by others, better antennas can help too. The sudden change is often due to foliage and similar environmental things. Our earlier rigs had roof-top antennas aimed carefully at the land- line house which had an omni antenna. The wireless community network was a WAN network, with an ethernet snaked into the house, and which also powered the roof-top basestation via POE. Oddly enough, you'd need another wireless basestation if wireless LAN was desired inside the house!

The only items that must be common among all wireless nodes in a Talisman/Mesh network are the wireless SSID and channel. If encryption is enabled, you must also use the same encryption method and keys throughout the mesh. The mesh firmware supports the Apple Rendezvous/Bonjour protocol for remote administration. Mesh nodes are automatically discovered and listed on any Macintosh computers connected to a mesh cloud. For Windows machines please download and install Apple's free Bonjour package for Windows from http://www.apple.com/macosx/features/bonjour . When Bonjour for Windows is installed you can browse and administer all mesh nodes within a cloud by clicking on the Bonjour button from within Internet Explorer. For Linux and BSD Unix please install the avahi Rendezvous/Bonjour suite." Marcus |

Mesh was certainly the conclusion we reached after working out the
logistics of a modest community network, especially with non-technical members. Our goal, after trying one, was to use an outdoor rubberized utility box which included its own plainer antenna with modest gain. The idea is to make it so simple to mount on the side of the house that by simply supplying it with the POE connection, it would configure itself and be a node on the network. Mesh networking was not widely working yet, and the key problem not solved was "bonding" multiple land lines in different homes. The hope was that as individuals within the mesh gained land-line broadband, they'd still want to stay on the wireless WAN because it would both offer increased bandwidth and a fallback when their broadband failed. Mesh is clearly the best way to go if you can get the software into whatever AP used. BTW: La Canada Wireless is a very effective community network: http://www.lcwireless.com/MainPage.html .. they don't yet use mesh, they've been in place for years and thus would face a huge conversion process. They helped us understand the difficulties/joys of a community network, and had all the war stories you could want! :) -- Owen On Jan 28, 2008, at 6:38 PM, Marcus G.

I'm on La Canada Wireless with close to 24/7 service but there are parts of the system that have to fall back on their modems with regularity. Even with large numbers of volunteer tech hours, they're not sure what causes those areas to fail. d- |
