Hi,

I'm trying to figure out what CLI commands are used to change the transmission fixed rate.

If I go to Wireless->Advanced Settings and change the Transmission fixed rate, I see that nvram's wl_rate and nvram's wl0_rate are changed to the rate I selected in the page. If I then go to the Status->System Info page, I can also see the new rate.

However, if I issue at the CLI

> nvram set wl_rate=<new rate> and
> nvram set wl0_rate=<new_rate>
> nvram commit

I can see the new rate reflected in the Wireless->Advanced Settings page, but not in the Status->System Info page.

What am I missing?

Thanks,
Gary

What are you actually trying to do? You realize that if you set it to a fixed rate, if the router signal quality won't support that fixed rate, you will get no signal at all? Which is why it is best to leave it on auto. At least that's how I understand it.

Yes I understand... but I need to be able to do it (a job thing).

So again, is there something else I need to set?

I don't go beyond the webgui, which I presume you have tried.

I believe that the wireless status shows the rate of transmission based on the signal quality, but am not sure how it does that given that there can be multiple clients with different connections and therefore different signal strengths. Also, it has been reported that if there is no traffic, you won't have a high speed.

I always use the throughput graphs to determine speed. And although my status will sometimes show 54mbs, I never get that speed on wireless.....never.

I believe its part of the specifications in wireless to auto-negotiate the best speed based on signal strength.

Even if you manually set a speed, the programming will re-detect wireless signal strength and then the auto-negotiate best transfer rate it can based on signal strength.

And like posted above, if you set the max transfer rate, but signal doesn't warrant that speed, you just won't get a connection at all.

Yea.. That was the part missing..

I always reboot either by command or a power cycle. It was just taken for granted..
