    How can I get WRT54GS to run at 251mw??

    I downloaded Thobir's HyperWRT WRT54GS_4.70.6-151005

    But all I can get it to run at is 84mw max.

    Also is it possible to have the router pass multiple ip adress from the ip provider?? Sasktel offer's me 8 with the extream package but I like the wireless??

    I haven't used Thobir's firmware so I don't know why you're stuck @ 84mW since the change log claims it supports 251mW... But if you're really intent on running with your TX power set that high both DD-WRT & Sveasoft support setting the TX power to 251mW.

    Yes but this requires a little more work and must be done from the command line. See if this post gets you headed in the right direction. (If not post back here or start a new thread with a relevant title.)

    if you use the drop down box percentages, it will go up to 100%(84mW), but if you select manual, you can type in any value up to 251mW. this is to ensure that if you want power that high, it can not be done accidentally.

    just out of curiosity, why do you want to pump it up that high? You're gonna need some extra cooling in your router to keep the radio from frying. Also, if you have the stock antennas still connected, you won't see that much of a boost in range. I tried boosting mine up pretty high before, and my link went farther, but the antennas didn't have enough gain to pick up the signal from my laptop's wifi card. Jst some food for thought...

    the Wireless signal becomes very dirty at 251mW inless you need to braodcast long distances ie miles i wouldn't recommended this.

    boosting router power

    I just wanted to see if can be done that's all. Thanks to everbody who replied. Sorry about 2 threads I am not very use to these fourms. << I will read the rules more carefully.>>

    What is a safe signal strength to use?

    I have a WRT54GS running Sveasoft firmware, don't remember which version, but it is over a year old.

    My problem is I need to reach a PC on the upper floor of a two story house. Router is on the lower level where my office is, and my son whose bedroom is on the upper floor needs to connect from his room using his desktop PC.

    My question is, what is a good "Maximum" signal strength to run my router at without burning up the transciever?

    You shouldn't go above 84mW for normal use (= no long distance links). It will make the signal noisy (resulting in low throughput) and could damage the radio.

    Thom_D, depending on how you've setup your antennas for TX and RX, you can put one antenna up and the other pointing to the side, (create a right angle or aim the broad side of the antenna towards the client on the other floor if it's not directly above/below the router) To get an idea of how the antennas broadcast signals, picture a doughnut around the antenna. The antennas do not broadcast straight out from the tips. If you have both antennas pointing up you won't get great reception on upper or lower floors. An example for my setup is, TX = left and RX = auto, I put the left antenna up and the right antenna pointing towards the right. I guess if you have them set both to auto, then you can chose either one to point up or towards the right or left. I hope this helps a bit 'cuz that's about the best I can explain it.

    edit: PS: the best spot for the router is on the top floor.

    Just because I just read across this topic, I cannot enter a value higher than 84 in the "Transmit Power"-Field! I am using HyperWRT, latest version.

    Strange...

    Please advise some more...

    Your message is going to be helpful for me. I am trying to setup access for groundfloor and one above. Our building is a cement concrete building and closed doors.

    Per your advice, I should be placing the Router on the top floor, right?
    Also, when you say Right and Left Antenna, I presume sides are when facing the LEDs.
    What would you suggest as an ideal transmit power, direction of antenna, configuration of Right/Left antenna. I have WRT54G with DD-WRT v22 with Linksys 7db Antenna.

    Thanks for any help you can provide.

    Wow, cool site. Interesting Projects for sure, will try sometime. Thanks Toxic!! Any particualr suggestions/tips based on personal experience with making such antennas...

    Regards.

    I made those reflectors from the diagram on that site, a long time ago and am still using them, went from an intermittently working signal with no reflectors to my computers 2 floors up to a strong signal around 36-54Mbps with the reflectors, I have alot of interference in my house.

    As the site says as long as you follow the curvature you can make them out of almost anything, mine were made in less the 10 minutes for the pair, where he uses the wire framing on the reflectors i used cardboard from a box that a 12 pack of soda cans came in, we drink alot of soda so it was available, you can easily use any thin cardboard or even thick if its all you have, I think thick will be a little harder to get a nice curve out of though, for the reflective surface I used aluminum foil, and to mount it on the antennas I just used some cardboard.

    To make the curve i just did it by hand and compared to the diagram, it doesn't have to be perfect just pretty good, at least for me, I just wanted quick and easy, not long and perfect.

    Re: Please advise some more...

    lynix,
    I'm using tofu's Hyperwrt for the G, and the highest value I can add manually is 99, but I then get a message that the value is out of range [0-84]. However, I only tried this to see what happens. I actually only use 100%/84mW. Thibor has his own version of Hyperwrt for the GS and he was the one who stated that you could go to 251mW manually. So, maybe it's only his firmware version that allows this.
