The catch with these add-on antannas is that they get you more effective power by limiting the direction in which they're broadcast. If you can find one corner of the house, you should be able to get away with an antenna that has just a 180 cone, instead of a full omnidirectional one, that will give you twice the effective signal strength. Also, if you access point has dual antennas, then you can leave one as the omnidirectional, and get a directional for the other antenna and point it at the problem spots. -- Frank Sweetser fs at wpi.edu, fs at suave.net | $ x 18 Full-time WPI Network Engineer, Part time Linux/Perl guy | Right now I'm having amnesia and deja-vu at the same time.

Well, I know of some people that have put two WAPs in their houses, at around the middle height in each half of the house. That would require shelling out another $150, of course, but they do get full reception anywhere in the house. Brian J.

Wireless antennas

by Andy Stewart

HI gang, I have discovered that there are a couple of locations in my house where the wireless network does not work well at all. Naturally, they are the locations where I most want to use my laptop. My access point is on the 2nd floor in approx. the middle of that floor. I'm trying to use the laptop on the 1st floor at one end of the house to (almost) no avail. Moving the access point to other locations in the room seems to make little difference. My house is not a mansion - I'm well within the 300 ft alleged range. My 2.4 GHz wireless phones have no problem over this particular path through the house (and yes, I turned them off in case they were causing interference). I have been looking at these add-on antennas that are available on the Internet. It appears that some are passive while others are active. Would this help, or is there some more basic solution which I've overlooked? Thanks, Andy -- Andy Stewart, Founder Worcester Linux Users' Group Worcester, MA USA http://www.wlug.org

Issues with aic7770?

by Keller, Tim

Has anybody done a Red Hat 7.3 install on a box with an Adaptec 7770 card in it? The machine was running *cough* the server version 4.0 of an OS that rhymes with "Empty" and working fine. However, when boot off the CD due to our buddy "El Torito" and INT13. The bios is able to get the diskette image but then unable to find the CD. I've got a ftp site with RH 7.3 so I point to it and everything works fine until I have to specify which driver I'd like to use for the scsi card. When I specify the Adaptec 7xxx series driver, the kernel issues an "Opps" and continues on. This machine is a 100mhz pentium HP Netserver. (yeah, I know its slow... I plan on using it as a standalone JBOD) Thanks, Tim.

I booted single user, removed the files, and then did init 5. Worked like a champ. at http:www.tldp.org, I also found a good NFS HOWTO. Things are working just fine now. We now have 66 Mhz Power Macs running linux-2.4.19-rc2, using a root filesystem stashed on an Intel server, and running X applications (KDE 3.0.1, Mozilla 1.0) also on the server, but displaying results back on the Macs. With this setup, the Macs appear to be turbocharged -- much faster than running the same stuff natively. --Skip

WLUG BBQ!!!

by Andy Stewart

Hi Everybody, Although I have not yet updated the WLUG website, the WLUG BBQ is going to happen! The BBQ will be held in Shrewsbury at Doug Waud's house like it was 2 years ago. Directions are forthcoming. Thanks, Doug! Our next meeting of WLUG will be at the BBQ on Thursday, August 22, 2002. The BBQ will start around 6 PM and go until Doug kicks us out (watch it, he has Steve as his bouncer). If you can't make it at 6 PM, show up whenever you can. WLUG will supply the food and munchies and will have sodas on hand. You may BYOB (beer, wine, whatever) if you wish. If you would like to bring a salad or dessert, feel free! Label your container with your name to insure its return. Doug has a swimming pool which we can use, so if you are interested, bring a bathing suit and towel. Its not clear to me if one must actually *wear* the bathing suit. We'll rig up some kind of projection system for a LInux talk of some flavor. It may end up getting used by some of you ASCII Art fanatics, but that's OK too. ;-) What good would a Linux party be without an Internet connection, a projector, and a laptop or three? Please RSVP to me and let me know that you'll be coming. In this way, we can be sure to have enough food on hand. Other party ideas? Send them out to the list!
