WRT54GS V4.0 - is this the hardware version to avoid?

    i read from other linksys related websites and they all stated flash vs system mem is 4MB/16MB and it current firmware v1.0.50 doesn't allow third party flash (the infamous "Upgrade are failed" message).

    i'm currently debating whether to keep V2.1 or V4.0 (i got both and will return one of them soon) and it looks like i'm going toward keeping V2.1 unless there are good revision fixes and hardware advantages on V4.0. does anyone know good reasons to keep the V4.0?

    it seems like V4.0 is created to discourage third party firmware flashing (with lower memory size and the same chip as WRT54G V3.0)

    thx :sadbye:

    tbh if you dont use the RAM withing the GS using JFFS2 support etc i wouldn't bother going for a GS now as some firmwares already allow Speedbooster within G models.

    darn, i didn't know the speedbooster can be software-enabled! but i think i'm kinda stuck with only keeping the V4.0 or V2.1 of the WRT54GSes. and with the rebate and everything else, it's about $10 difference (compared to the G) which is not bad.

    so Speedbooster is available via firmware? Which one? I would imagine the wireless adapter need to be enabled too?

    I also have a v2.1 and a v4. I like the v4 so much better than the v2 GS I had.

    I had to "fool" the v4 by installing dd-wrt v23 (basic generic) to unlock it. After it was unlocked, it would run either dd-wrt (of course) or (because I can't figure out dd-wrt's too-many options) it will now run Thibor's 170905 "GS" firmware. After this trouble, I did a hardware reset. And, all is well with it.

    There was no trouble running anything I wanted with the nice v2.1! It is fine, fast and strong. So, keep the v2.1, by all means.

    I'm not knocking the v4's current performance, but it certainly is a "cheapened" product compared to the full-quality v2.1

    Speedbooster enabled by firmware


    If you can hold up your WRT and see a square of light through the vent, then this indicates the smaller motherboard that is exactly the same motherboard used by the V4 GS. That's right, the V4 GS has half as much memory as a real GS (exactly the same as the G). Having said all of that, I've got to mention that the new model is very well behaved and works great with the new firmwares.

    My firmwares of choice for this are DD-WRT (basic generic 23) and Thibor's 170905 HyperWRT.

    Both of those can enable speedbooster.

    But, there's a reason you might not want speedbooster. It won't connect speedbooster clients at long range. It is designed to provide wireline speeds at short ranges.

    My approach to speedbooster is to use it with regular "G" clients and to disable speedbooster in the client's drivers if the client isn't getting at least 3 bars (or if it won't get an IP address).

    The advantage of it is not exactly as advertised, yet it is beneficial.

    It lets frame burst work to cause a speed increase, so that is a good new thing.

    And, it is helpful in a radio-dense environment. I tried a WRT with speedbooster and one without. Each one was sitting at point-blank range to each other, on the same channel, and with different SSID's. Speedbooster was not in use on the client (computer). Two other high power AP units were running nearby. Speedbooster got through at 24 megabits, which is exactly the speed expected with WPA-AES, standard wireless "G", and zero interference. There wasn't zero interference.
    Bravo Linksys! But, why isn't it a standard feature?

    wait WTF ? I got a CGN6 and thought it was some hot new one and now I find out they jipped me on half the RAM and ROM?? I don't use wireless at all and got it for running all the hot firmwares (got the GS for the larger RAM and ROM) on it so I'm wasting my money on the CGN6 GS. :cry:

    Is the WRT54GS one I am shooting for the CGN5 (V3) ? I'll just buy at Wal-Mart and switch them and return it since I haven't opened the CGN6 yet.

    Well, the "pick of the litter" is the V2.1 and it is CGN4. Operating at a high speed, very low lag, and able to boost the radio way high without problems, the V2.1 GS is my favorite of all of the Linksys WRT. Good luck finding one.

    pending your country of origin....they are easy enough to find right now. Walmart's have them in enormous abundance. 2 Walmarts around here and all of them on the shelves are v2.1

    The Wal-amrt out here only has v3s. I just bought a second wrt, an I got a v3, since that's all they had. I have a v3 in production service right now with the stock firmware and it strolls on along.
