Does anyone know how (or where) to adjust the signal strength on a Linksys BEFW11S4 Wireless router?
I have done everything I know to do, added the high gain antennaes, etc to try to get wireless signal in the other end of my house (<100ft away) but the signal is very low and will drop frequently.
I know on the newer routers (802.11 b/g) there is a firmware 'hack' that allows you to manipulate it... I don't want to 'hack' it... just put out the most power that it can.

I work for a wireless internet service provider and specialise in these things.  For your situation I do not know if your building is concrete or wood or steel.  However, guessing from your signal streagth problems even though you put on a high gain antenna I would have to think that your building is not steel.

I would suggest first off that you get a good high gain antenna.  There is no place on the linksys to adjust the signal strength and even if there were it would already be on 100%.  Here is a great antenna that I find works great in 100-200 feet internal shots.  It make look a little tacky but it does the job.

You will need a pigtail for your linksys as this antenna comes with a non tnc fitting.  You can find these the tnc fitting that you need at hyperlink technologies.  If you are having problems recieving the signal on the other end on the recieving device try getting a 9-10 db patch antenna to put on your recieving end.  

Also in emergency situations where you have walls all over the place you can place mirrors around certain areas to increase reflection.  Believe it or not this does help.

The best thing I have found is using an external usb wireless nic at the laptop end.  It's an extra piece at startup than the integrated nics but signal strengh can be 30 to 40% better 6 inches one way or the other.  It's hard to put the laptop in just that place or set you remote tower up on top your work area to get the best reception but you can velcro your USB wireless nic wherever the signal is the best.  Also try configuring your Linksys router to use a different channel than the channel #6 that comes from factory.  Chances are you have 2 or 3 neighbors on the same frequency possibly causing unnecessary interferience.  " Please also configure at least WEP on your router and remote units for your own protection if you haven't already" see this if you are interested : http://www.experts-exchange.com/Networking/Q_21045221.html?query=is+my+wireless+secure&clearTAFilter=true

Thanks for the advice, since craigmyster answered my question (how to or can you adjust), that is who I am going to award the points.
mtpcbypc - my closest neighbor is over a mile away, so interference isn't a problem :)

My walls are made of OLD thick sheetrock/plasterboard, and who knows what else behind them, the house is 60+ years old I don't know if that has anything to do with it, also my wife would shoot me if I just started hanging mirrors...

Both of you gave good advice... keep up the good work!
