[Asus RT-N56U] 20Mhz 72Mpbs or 40Mhz 150Mbps?

[AshCation]

Hello guys , I was using firmware 3.0.0.4_342 then I changed to firmware 3.0.0.4_374_239 , I used the same settings for wireless 2.4Ghz:

Wireless mode : N only (B/g protection unstick)
Band Signal : 20/40Mhz
Channel: Automatic
WP2 Personal
AES

This new firmware looks the same on the download , upload , ping , jitter tests , my notebook have a Realtek RTL 8188CE NIC(150Mpbs), with old 342 I get 150Mbps near the router and 60-120Mbps 2 rooms away , but with this new firmware I got 72Mbps near and 45Mbps max 2 rooms away.

Of course when I try move files over wireless my speed previously was 7-9 MB/s and now 5 MB/s max , near the router.

Then I tried change the 2.4Ghz settings :

Wireless mode : N only (B/g protection unstick)
Band Signal : 40Mhz
Channel: Automatic
WP2 Personal
AES

Now I have the exact speeds and range of the old firmware BUT my ping and jitter looks like more unstable , and I play online games

What you guys think ? I dont know why with this new firmware my notebook NIC suddenly started working only in 20Mhz , now I dont really know what to choose , I think some devices dont support 40Mhz..

Also I think this router range is terrible , my house is small , 1950ft² or 180m²,only 1 floor , and in some places with the old firmware my notebook NIC only get 15Mbps and 4 signal bars , but I can use my 10Mbps internet at full speed with good ping and jitter.

Thanks!

You know, 40MHz. channel width needs to have two clear channels to work well, which is not likely to be available in most locations. Otherwise, it will tend to be unstable. I'd suggest using something like inSSIDer to find your clearest channel, and try using that single channel with 20MHz. channel width. That should stabilize your signal. Try to focus on channels 1, 6, or 11, too, they're the only non-overlapping channels here in the US.

If you're finding throughput on the 374_239 to be less and/or shorter range, that was my experience as well. I found a difference of about 2 bars between the signal strength in my living room, so went back to .342 firmware. You don't have to go forwards, you know, only if it helps you in some way *smile*. So far, new versions after .342 have not been better for me, the wireless functionality has been much worse, so I've stayed with .342.

Thanks mate , I will try use this settings a little longer and then switch back to 342 and find a good channel , I was using 3 , but looks like 2 more networks use this channel too , 1 , 6 and 11 have some networks too , the router automatic selected channel 8 + 4 extended channel , lets see this channel in 20Mhz.

I dont know very well understand inSSIDer , what is important to know?

If you want max speed out of your adapters it must be on 40 MHz ONLY!

You mostly want to see how strong the signals from your neighbours are, and to find the location in the channel range where you can get 3 channels with the weakest interferences (or in the case of 40 MHz, 5 channels with the lowest amount of interference - now you see why stable 40 MHz is nearly impossible on the 2.4 GHz band with only 11 channels available).

InSSIDer is a program that you can run on a wireless client (laptop or Android phone, etc.) that does a wireless site survey. It can list all the wireless networks that are within range and their relative signal strengths so that you can find the clearest channel. It's also useful in orienting routers and antennas to get the strongest signal where you want it. A very useful tool for tuning up your wireless network.

There are other programs like it, but inSSIDer is one of the best known ones.

Hello guys I switched back to firmware .342 and Im using 20/40Mhz mode , I read about using 20Mhz only for better wireless coverage but I need 40Mhz speeds sometimes.

I used inSSIDer Office to test a few things , looks like my area have 25 networks in Channel 1 , 20 in Channel 6 and 10 in Channel 11 , and of course lots of networks in others Channels , Asus automatic choosed Channel 1 but I changed to 11 , lets see if it works fine.

Thanks all for the replys.
