I have Tomato 1.19 from victek.
How do i enable the booster??
125 High Speed Mode (aka Linksys SpeedBooster) is controlled by "Afterburner" on the Advanced : Wireless Settings page.
Speedbooster is just a gimick. It's probably nowhere as fast as it's hyped up to be.
Remember that smb. must have the router AND the wireless client (usb stick, pci card, another WRT as client) set with afterburner on or auto.
I have not tested between a WRT with a wireless client.
But from my tests between 2 WRT in either Wireless Ethernet Bridge mode or Wireless Distribution mode, disabling Speedbooster has better throughput than enabling Speedbooster.
Some numbers? I believe you just that I'm curious what's the difference...
No problem... I get around 25Mbps with Afterburner disabled and around 20Mbps with Afterburner enabled.
If I recall, the Broadcom wireless drivers that Linksys ships do not support 125 High Speed Mode (aka SpeedBooster, Afterburner, Turbo G, etc.) in anything other than AP (access point) mode. I definitely remember that it was not supported in WET (Wireless ETernet bridge) mode.
I found I got 30-40% faster performance with only one client, but it was a bit less from there with me for 2-3 clients, and then at least for me it made no difference at all with 4-5 clients. It's worth noting that some of that performance increase came from Frame Bursting, which in the original Linksys firmware was part of "SpeedBooster" while the "Afterburner" setting refers only to the hardware-based frame compression... so to recreate Linksys' "SpeedBooster" implementation you have to enable both. Lastly worth noting is that Frame Bursting was supported just fine in WET mode... but again is of limited use once you start adding more than a handful of wireless clients.
Here's an article at SmallNetBuilder with some 125 High Speed Mode performance testing. They showed 46.5% throughput increase, but I'd not seen quite that much performance when I was playing with 125 High Speed Mode a couple of years ago.
Hmm, not a small difference...so, better with afterburner off. Good to know, thanks!
We all talk about WRT with Tomato on them ) we are on ''Firmware Projects for Linksys Devices > Tomato Firmware > Speedbooster'') so no need to mention the few options we have on stock firmware...
They are equally applicable to Tomato, as Tomato's wireless heart beats with the same Linksys-delivered Broadcom wireless drivers. It has the same functionality/restrictions, except clearly the UI allows much more flexibility in configuring SpeedBooster (aka Afterburner + Frame Burst).
I understand now, sorry. But why in Tomato, at bridge or client selected option, you have a clear ''speedbooster on''-option?
Just the way it is I guess... you can actually configure lots of things that the wireless driver doesn't support, for example WET mode using WPA2/AES. The Broadcom driver doesn't support this combination, and you'll find your WET won't connect to a WPA2/AES AP, but you can configure it in the UI. (It does, however support a WET in WPA/AES connecting to an AP in WPA2/WPA AES, I used one in this mode for almost two years.)
Another thought: The "ND" version uses a newer Broadcom wireless driver, so it may support things the old one does not, and vice-versa. I don't know what's different though, as I stopped playing with Tomato wireless once the WRT600N was released and bought one to become my AP. Tomato is still my main Internet router, however.
Perfect explained, thank you! :clap2:
