Buying Larger Antennas for WRT54G

    Hey. I'm trying to increase the distance and speed for my WRT54G. I some computers that are far away, I only get a 48MBPS "low" connection. If I were to buy two fo the high-gain antennas from linksys, would this help increase the performance?

    Thanks
    John

    depend on how far you are. and do you get those results with the staock antennas

    antennas

    well. The router is about 15 feet from the computer.. but it goes through walls and stuff. I'm getting a 48mbps and lower "low" connection with the stock antennas

    then you might see a increase.i have have these antennas and they work great. i have the router sitting between two floors and i get a good conection all around the house even on the 4rth floor in the basement and the basement is mostly made of rock and concreat

    ok cool. Maybe ill look into some. Just curious, what room do you keep your router in? Do you keep it out of the open or like in a living room of some sort?

    The antennas will help, but you can also use a 3rd party firmware (like DD-WRT, HyperWRT, or Alchemy) to boost the power to the antennas. In my house, I was having a very hard time reaching up a floor and any distance away horizontally, but with high-gain antennas on the router and the PC on the upper level combined with an increase in the power level, I get a nice stable connection (using Sveasoft Satori firmware). Of course, there are still areas of my house that are unreachable unless I use WDS. WDS may be what you need in the end though it'll cut your wireless speed in half.

    here is my (parents) house setup

    1st floor basement (gets good signal)

    2nd floor (main floor) livingroom/dinningroom/kitchen (gets good signal)

    3rd floor master bedroom (where the router is) 2 guest bedrooms (gets xlent signal)

    4rth floor 2 more bedrooms/ atic (gets good signal)

    ok. gotcha. I also have an apple airport express and I have that setup through WDS with my router (im using satori). Since that is configured with WDS, is it cutting my network speed in half then? I really haven't noticed any performance issues though.

    Hi folks,

    Pardon me for burging in. I just got myself a WRT54G v2.2 today after strong recommendation from many people I spoke to. By the way, I discarded my DLink 624+ (my AP) and DLink 2000AP+ (a repeater) after bad experiences (their Singapore's service support is good though).

    I've downloaded Alchemy (think the version is 1.0) and would like to tweak the signal strength. I was wondering how much should I tweak it to. Would I "burnt" the ROM or something?

    Appreciate any help.

    Wongster :)

    up to 64 is generally recommended.. Anymore then you can run into noise and heat issues. If need more, try the antennas mentioned in this thread

    Thanks bluedog. I was at my local IT Shopping Mall. Quite a few retail outlets have this 2 antennas thingie with TMC connectors. Is this the one you spoke about?

    Probably the same...

    Here is a picture of Linksys brand antennas, I am sure there are aftermarket ones. Also, I don't have these, I use Alchemy 1.0 ...soon to be dd-wrt (as soon as I am confident, I won't rebrick my router in the upgrade)

    Anyway here is the link

    http://www.linksys.com/products/product.asp?grid=33&scid=38&prid=643

    The connection is TNC.
    Jagboy could probably tell you a little more as I think he mentioned he has i mean, uses, some bigger antennas. :wink:

    yes these antennas are great that bluedog was talking about. i really like these antennas. before with the stock antennas i could not get good signal all around the house. but adding a fan for some reason gets a way better singal i guess that it keeps it cool. if you are not a modder you could do with out the fan.

    Hrmm.. Interesting

    I've got a WRT54G running wifi-box.net's firmware, and, honestly, I love the firmware, just hate the performance.

    I had an old POC (piece of crap) D-Link 802.11b router that had awesome connectivity all throughout the house, but I upgraded to the Linksys WRT54G for the faster performance. Now, for the past 6 months, I've dealt with the fact that, although I placed the unit in the exact same location as was the old D-Link, my connectivity on any other floor is spotty to non-existant.

    The unit is located in a cooled computer closet in the basement (finished), providing 54Mbps coverage to the basement and about 2/3rds of the 1st floor, and about 1/4 of the 2nd floor. I can forget about stepping out on my deck as signal seems to drop the instant I step over the threshold. The old POC D-Link allowed me to sit on the deck and browse the net.

    So, I was thinking that it was about time I did something about this, and I saw this thread. So, I thought I would ask:
    Would I be better off buying a high gain antenna or buying another WRT54G and placing it on the 2nd floor somewhere on the network (aka: make it work like a vanilla access point)?

    Ok.. I dumped wifi-box.net and installed Alchemy (Sveasoft). Seamless upgrade, really. Sveasoft is lacking on the number of port forwarding options, but I'm only one shy of filling up the page. No biggie, but doesn't leave room to expand much.

    Anyhow, wifi-box's firmware allows for power boosing up to 81mv, but Sveasoft's allows for going up to 241mv. Once I tried that, I had much better coverage.

    Fortunately, the unit is in a nice cooled room. Otherwise, I would guess, it would be complete toast after a few days. :) I am still considering attaching a small bun-type fan to the exterior of the case, though.

    dd-wrt pre 5 has 30 portforwards. which is really cool . and dd-wrt is much more stable. or go with dd-wrt pre4 which is also as good instead of alchemy
