I flashed my Linksys wrt54g to use dd-wrt firmware. The advanced routing functions of DD WRT are amazing. However, I'm not so sure about the transmission rate. The default tx rate is 70. I've read in the past that excessive tx rates will cook the router. But I need to turn up this rate to overcome some of the natural impediments such as double row brick walls, plaster, and several floors. Has anybody used this and if you have , whats your experience with moving off of the default tx rate?
thx in advance
perfect...thanks for your help. Warranty was never an issue, the house I own is. I'm even now thinking about getting another to use as an access point. But I do appreciate the info...
what do you suggest?...I've seen where some Linksys models use 35 mW. So the default on DD wrt is already raising that signal 3dB. And is there anyway to monitor the signal, a sort of crude way of knowing which direction works best for me? I'm thinking either download testing or maybe online video stream monitoring. What would you suggest?
There are lots of network benchmark tools (Link Removed due to 404 Error). And there are a bunch of wireless testing tools (Best Wireless Testing Tools - Spiceworks Community). When I am doing AP testing, I set up a laptop as the data collector/control. I use something simple like NetStumbler. I collect at least fifteen minutes worth of data at each power setting.There is no single, right answer. Here's the path I'd suggest. Use DD-WRT. Start with 28mW. See whether you can get a stable signal. At that power, the signal will be clean and clear, but a little weak. Then try 70 mW. Finally compare this to 89mW. I WOULD NOT suggest going higher than that. Too much noise and too much heat. ...
I did try inSSIDer which is at inSSIDer | MetaGeek . Free utility that monitors signal as you walk around on laptop. The question I have is this. The tx power was set at 35 mW and my signal strength was floating around -75 dBm. When I set the tx power back to 70mW, my signal went to -55dBm. Don't I want to keep the 70 mW to bring me closer to the theoretical 0 dBm which is true signal?
I appreciate the input gentlemen... In my setting ( Double row brick house with plaster walls, 3 floors with router on 3rd floor(only place possible)) the laptops in question seem to receive the signal regardless of what Tx power I'm using. The strength seems better at 70mW however it seems to hang every now in again on both settings (35 mW and 70 mW). This is more of a nuisance than a deal breaker. You have to know however, that this house is built like a tank so the houses natural impediments are more than likely the cause, or so I'm starting to think!I am wholly unfamiliar with inSSIDer. So I can't speak to the numbers you've quoted. As a general rule of thumb, the received signal power range for 802.11 devices varies from -60 to -80 dBm with a theoretical maximum signal of -10 dBm (dBm - Wikipedia, the free encyclopedia). [Note: my ability to convert to dBm is not as good as it used to be.] If you don't see a lot of lost packets at 70mW, then use it. My point was that some systems actually transmit less real data if the power is substantially boosted because there is so much noise and data retransmission. Again, most second-hand anecdotes indicate that you SHOULD NOT boost the signal beyond 89mW.
Have you found that by boosting to 70mW, you are getting better data transmission throughput (as measured by tools like BroadBand Reports (Lost in a forest.. - dslreports.com If so, continue to use 70 mW. Just ensure that you have adequate ventilation where you place the AP.
BTW, were you able to use an external antenna for the computer that is having trouble?
