WiFi config: TP LINK TL-WN822N and ASUS RT-N16

[Kyanzes]

I have these: TP LINK TL-WN822N and ASUS RT-N16

Basically, they work rather nicely together, no drops and solid signal.

My only predicament is that the TP LINK TL-WN822N is supposed to be a 300Mbps adapter and, AFAIK, the RT-N16 does support this speed (hence 20/40MHz mode).

In the ASUS' wireless config 20/40MHz mode is enabled.

When I check it with a utility, it's clear that the communication between the two devices never involves the extension channel. Hence, throughput is always half of the expected 300Mbps.

I've tried to re-flash my Asus to the newest 3.x firmware to no effect.

It is stated on the TP-LINK site that the WN822N is capable of 300Mbps.

The TP-LINK utility offers no settings, and also couldn't find any relevant settings in the device manager entry of the adapter.

It seems that communication is always at 1x20MHz, no matter what.

What could be the problem here?

Using this might help you narrow down whether the problem is with the router or adapter:

Thanks, that's what I used to check if the extension channel is being used or not. Unfortunately, it can't say much more than that. It's an info in itself, but I can't go on from here.

So is Inssider reading the full 300mbs link speed? What do your transfer speeds look like? If you're only getting about half of that 300mbs that is normal. I use this to test my transfer speeds:

You might get more help if you get a mod to move this thread to the networking forum.

Inssider shows 130Mbps no matter what I do.

I could not make it work with two different ASUS firmwares. Fiddled with settings to no end but nothing would make the client and the router connect at 300Mbps.

In the end, I switched to DD-WRT firmware and my client adapter insta-connected at 300Mbps, using two channels. Could finally also alter TX power.

That's it.
