    Hi

    I recently bought the Hig Gain Antenna's for my WRT54G, but I have no idea how to remove the existing antenna's. Can somebody out there help me? I tried calling Linksys, but they didn't help me.

    You can remove the antenna by holding the top of the antenna and twisting it counterclockwise, facing the back of the router.

    I'm twisting, but nothing seems to be happening. Do you just mean rotate it counterclockwise until it comes loose?

    you have to fold the antenna straight

    |
    |
    ->-- <- normally it's like this
    make it like this:
    ->----------
    then theres a little black cap near the router you have to yank on that a bit it should slide away from teh back of the router, then you'll see the screw on potion, if you unscrew that it should come off.

    Thanks for your help, I figured it out. One followup question. Now that I have the HGA7T's on should the base of the metal connectors be exposed?

    don't have those antennas but that may be the case, you can try to slip the cover on over the new antenna's if you'd like but it shouldn't matter either way.

    Well, since I can't edit my posts I'll make a new one. I can't seem to get the covers off the old antenna's, and I don't want to break them, so I'll leave it as they are. Anyway, I only seem to be getting a marginal signal increase, 50% to 53%. I'll give it a day or two and see what happens.

    As another questions, instead of starting a new topic, what would you all say is the minimum reccommended signal for a good connection. Before I installed these antenna's I was getting signal of 45-60%, avereging at 50-55% on my laptop. Would this have been OK?

    if the antennas are straight the cover should just slide right off...
    how far away are you from the router? the antennas aren't going to make a massive difference but they should increase it somewhat...
    50-60% should work you won't notice issues till you hit about 30-20% then you may see occasinal drops...

    Sorry for the long reply.

    The router and my laptop are on different floors of the house. The router is on the main floor in my parents office and my laptop is in my bedroom in the basement. The overall distance is probably 30-40 feet. Its something in my room that affects the signal. If I move the laptop 6 feet away from my desk my signal jumps 15-20%. Its crazy. Right outside my bedroom door (15 feet away) the signal jumps to the 80's and 90's.

    The antenna's don't seem to be making enough of a difference to justify the $69.99 so I may retuen them. As I type this mesage my signal is alternating between 47% and 67%. The signal almost never drops below the 47%. I'll try them out for the day and see what happens.

    based on your results it's probably not worth it for 2%... you may want to install netstumbler on your laptop and see if theres another wireless device in your area causing interference, also check for any 2.4gig cordless phones that may be interfering... you can also look for noise in netstumbler going up... could be metal or wiring causing noise around that area in your room... you may want to look into a directional antenna, or a range extender... the other thing you can try is changing to a different channel, try them all and see if any makes a difference in signal strength.
    let me know what happens.

    yes alone the hg7at's suck but coupled with dd-wrt you can up power to around 50mw which is 2x normal this should kill your neighbors cordless and whatever is interfering with you as well as make your router much more powerful to get into your room and make your connection much better

    I'll register when I get a chance. Too tired now.

    I tried downloaded NetStumbler and it wouldn't detect a wireless card. Weird.

    I do have a few 2.4 GHz phones in my house, and I've already moved them, and I can't move them anymore without my parents killing me. Anyway, like I said, I seem to be getting a 50% signal most of the time so I don't think I will put out the extra money for these antenna's or a range expander. Actually I did buy the range expander, but it wasn't working for some reason. I was getting a 100% signal, but I wan't able to connect to the internet. Plus it was just too much money.

    Try downloading HyperWRT to try boosting the power output, its a good place to start firmware wise and adds the ability to increase power output on top of the latest Linksys firmware. This might help you get the increased signal strength you need.

    In setting up the WRE, you need to make sure that the Range expanded was connecting to your router. My parents purchased one to expand their signal up to their bedroom, but couldn't figure out why they could get a signal but no internet. Similar situation - you have to set the Range Expander to connect to you AP/Router and this requires more than the push button if you have Security enabled - the directions included with the unit are a great explanation.

    Come on, register - it takes no more than 57 seconds ;-)

    hm netstumbler doesn't like some network cards, have you tried the other channels yet?
    re the phones: if you can late at night when your parennts are sleeping, unplug them all and take out all the batteries and see if that effects it.. alternatively you can build a faridade cage and put your parents in it :)

    I registered! It took more than 57s, I think it was 58 :p.

    OK, I don't think the phones are the issue because when I move my laptop CLOSER to the 2.4GHz in my room the signal jumps to 80-100%. It must be something at my desk. The 13 feet (I measured it) from the phone to my desk causes a 10-40% signal decrease. I have one of those handheld 2 way radio's on my desk that is always turned on, could that be causing the signal drop? The radios are used as an intercom between my room and the rest of the house. Besides that I ahve no idea whats going on.

    The WRE was weird. I set it up usung the directions and it didn't work, securuty was disabled. It took forever to install too. It took 4 restarts because different error messages kept on coming up. Then I saw that I could buy then antenna's so I returned the WRE and got those, which don't seem to be doing really anything. So those will be returned to. As I write this I've got a signal of 53% and a Quality of 47%. Thats pretty much what I got with the old antenna's.

    I have no idea what to do anymore.

    I'll try to download that firmware you said tomorrow. Its 4:30AM, and my insomnia is starting to wear off so I'm going to go to bed.

    hi gain antennas help out incredibly outdoors at base power. but indoors with the antennae you will need to boost the power to punch through tthe walls this is a must. dont up the power more than a few mw without the antennas or you will be buying a new router.

    as opposed to buying the antennae from a retail store for 60 bucks go on ebay or buy.com i have seen them on ebay new in box for 30-40 bucks and on buy.com im pretty sure they are 39.95
    compusa has a house brand that claims 9db gain but they are conciderably bigger and more annoying. but they are cheaper (35.00)

    if theres a small area being affected there has to be something there, is there a wall around there? whats on the other side of it? have you tried turning that radio off?

    in response to t4th: so I guess cranking my wrt to 250mw with the stock antennas is a bad idea :p doesn't seem any worse for the wear thought I only did it for a couple mins while I was outside :)
     
  20. Miromc

    Yes, there is a wall blocking it. My desk is in what was once a closet, so there are walls on three sides of it, 2 main walls and a little walls that sicks out about 2.5 feet. This wall seperated the wall into 2 closets. Also on the room adjacent to mine there is the storage room, which also houses the fuse panel, cable wires, telephone wires, etc..., but those are all on the far end of the room, so I can't see those causing any of this. I also turned off that radio and there was no difference in the signal. I would bet it is that little wall that is doing this.

    Now if I were to download that program how much would I want to increase the signal by using the original antenna's, since I plan to return the HGA7T.

    Now, I live in Canada, so all those prices I was given have to be increased for me, and I don't think I will buy anyhting else to try and improve this. Maybe, I don't know.

    where in canada? i'm in winnipeg...
    electrical wires can interfere with wireless specially if it's high voltage stuff where the power is comming in in that area directly around where the signal drops off?

    Miromc Network Guru Member

    Hey, I'be got family and a few friends in Winnipeg, its a nice place. I'm in Ottawa, well 30 min outside of the city.

    I would probably say that my laptop is 10-15 feet from the fuse panel, with the wall in between us of course.
     
  23. Guyfromhe

    Guyfromhe Network Guru Member

    it's an ok place when it;s not snowing :p

    hm is that the place where the signal usually dies out? or is it not near there?
     
  24. Miromc

    Miromc Network Guru Member

    It must be this wall. I unplugged my laptoop, took two steps back and my signal jumped to almost 70%. As I walk out of my room the signal goes to 100%. I walked into the storage room and I was getting a signal of 56%, so I think this wall must be doing it. Now, as I write this, back at my desk, I am getting a signal of 60% and a Quality of 73%, but that will dissipate to 50 in an hour or so. When I am reading the signal to I look at the Quality percentage, or the SIgnal percentage?
     
  25. Guyfromhe

    Guyfromhe Network Guru Member

    just thoughtg of something, pop into that electrical room with your laoptop see how the signal is when your standing near that wall...

    sorry i joined this thread so late......

    but one piece of advise i can give you is dont buy a range expander
    try the firmwares if that does not help...
    then try getting a usb wireless adapter d-link is the best in my opinon linksys does not make good wireless adpaters. if you dont belive me look at the wireless adapters forum....

    but anyway get a long usb cord and put the adapter somewere that is gets good signal. or get another wrt and do wds or client(sorry i dont know the difference). but dont get a range expander. fomr my know how they are hard to setup and just a bother. the 2 wrts in client or wds should do the job, i think
     
  27. Miromc

    Miromc Network Guru Member

    I did, the electrical room was the storage room and I got a signal of 56%. I think you all said that as long as the signal is above 50% you should be good, so I feel confident that if I download that thing and boost the signal a bit (how much should I go) then I should be safe.
     
  28. jagboy

    jagboy Network Guru Member

    you should go about 100mw i have been ruunning at around this for about almost 2 years. ofcoures i bring it down every now and again to 80mw or 70mw when no one is around

    and yes and no it is safe butthere have been posts that it can cause more wear on the router. but the price for the wrts are going down dont know about canada

    their like $90 cad after tax and rebate, etc for the non -s models
     
  30. Miromc

    Miromc Network Guru Member

    I paid $89.99 for mine and I've got a $15.00 rebate with it, so it only costs me $75.00. Not bad.

    After reading that that software can damage my router maybe I won't download it. Obviously there is nothing I can do to boost the signal besides get a range expander, which I'm not going to pay when it seems tp be working without it. Jagboy, I can't try your option, its just not an option for me.

    Miromc,

    The comments about possibly damaging your router apply to ALL firmware upgrades no matter whtether third party or OEM. There's always an inherent risk in flashing a new firmware whether it be to a DVD drive, your motherboard BIOS, or to the Linksys router. The disclaimer is much more of a CYA. Even in the case of a failed flash, there are many ways to 'fix' it. Its like saying, just be careful when using cell phones, you *could* get cancer. For that matter, you could also win the lottery, again CYA.

    If you make sure you follow the instructions, you'll be fine. Only upgrade from a wired computer. Do a full reset to defaults, wait to make sure the router is loaded up, upgrade the firmware, reset again to router defaults after sucessful upgrade, then you're good to go.

    Regarding the power outpu levels, I tend to use either 68 or 86mw. The've just always sounded like nice round numbers to me that tend to give the needed boost depending on the situation. I've been running for over a year power boosted on all my WRT54G and GS's without problems.

    But again, thats the point of the forums, to provide you with the best possible information for you to make decisions regarding solutions to a setup. So, make sure you take in all thats available, and I'd suggest don't be scared away by the CYA disclaimer. Heck we put it on every beta firmware news post - "don't blaim us if it doesn't work, we didn't write it, and its not official"

    Good luck with finding a solution that works for you. If you still having problems with one directional area, you may also want to look into constructing a reflector - this won't cost you more than $0.15 in materials for piece of card/paperboard and some alumninum foil. A quick search on reflectors should find you something. Maybe I'll try to pull together the link and post it.

    I built one of those, seemed to work but I needed the onmidirectional more than anything so I took it off...
     
  34. Guyfromhe

    Guyfromhe Network Guru Member

    Knock down the wall... problem solved :)
    quality and quantity are both important... the strength is how loud the signal is and the quality is how much noise is there, if you have 100% signal and 0% quality (100% nosie) your not going to be able to communicate...

    re: the router cost, you forgot the tax (unless you've got a way around in in wich case let me in on the secret)

    and re custom firmware: i've ran it on 4 routers so far wihtout any issues (well except for 1 but that was a stupid mistake on my part)., anything can be broken updating firmware bur if you follow the instructions your not likely to run into any problems ...
     
  35. jagboy

    jagboy Network Guru Member

    or there is another option Miromc you could just sit there and wish you had the siignal strength or you could just take like 5 min flash the firmware and if you dont like it switch back.
     
  36. Miromc

    Miromc Network Guru Member

    Yeah, I'll download the firmware. I'll tell you how it worked.
     
  37. Miromc

    Miromc Network Guru Member

    OK, I downloaded and installed the firmware, but I still don't see much of a difference. I have the Transmit Power at 100% (84mW). I guess that is the highest can/should go?
     
  38. Guyfromhe

    Guyfromhe Network Guru Member

    you can turn it up to 250mw via telnet but I wouldn't recomend doing that if you like your device...
    you've got a really weird issue, it's prolly something to do with that room...
