Advanced Wi-Fi router settings. Question for wireless experts

Hi all. My NETGEAR WNR3500L router works in Wireless Network Mode - N Only

4 devices are connected to it, also with n adapters (no more than two work at the same time). The speed does not suit me very much, so I decided to trick something in the wireless network settings.

Tomato firmware installed. It has some parameters on the Advanced - Wireless tab. What are the best ones to ask? Who knows, please help. For convenience, I made screenshots with possible parameter values.


Afterburner is one of the technologies for increasing speed when using the 802.11g protocol. "Acceleration" is achieved by removing "extra" service information from the transmitted data, while leaving only those data that cannot be dispensed with. In addition, data compression and forced packet acceleration are used. Such equipment can be distinguished, for example, by the SpeedBooster or "125 High Speed ​​Mode" logos.

Should it be enabled or not?


I didn't google anything about it. But the speed of 1-2 megabits is embarrassing =)



Didn't google anything.



CTS Protection Mode (Selective Transfer Mode). This feature enhances the access point's ability to receive all 802.11g transmissions, but greatly reduces network performance. Select Enable if you want to temporarily enable this option, or leave the default setting, Disable, if you want to disable it. In most cases, CTS Protection Mode should be left disabled and only enabled when there is a severe problem signaling an access point in an area with excessive 802.11b traffic.



Frame Bursting allows you to increase the bandwidth of the connection when communicating between 802.11a, b or g devices by reducing the costs associated with working in wireless networks.

Enable or not??



What kind of fruit is this? And where are my crazy 150 megabits of n standard? =)



What kind of preamble is this?



n preamble

Again, where are my crazy 150 megabits? =)

Thank you in advance for your help

Tomato has a Basic->Network channel scanner, run it and see if there is another access point on your channel or on neighboring ones.

Fill in the standard firmware and don’t steam people’s brains, dvdrip stuttering is a tin, and here n the standard is not clear when dvdrips fly on g, measure the speed when copying, otherwise it stutters to measure the speed when playing a DVD, maybe everything stutters because of the codecs .

Here about the settings in detail http://tomatousb.org/settings

The people, thanks to everyone who advised me to scan the channels. There were 4 more points hanging on my channel, one of them in the next apartment gave a good signal (4 out of five sticks). I switched to another channel, today I watched 720p without lags!

It looks like Pomodoro doesn't support 802.11n for your device (or doesn't fully support it).
Leave the settings as they are, try another firmware. Return the stock to start, then try the rest of the alternative.
What are the Rate values ​​on clients?

I think it still supports. Here is a screenshot from the connected laptop.
But the real speed is certainly far from the one in the picture

The point will stand out like n, everything is nishtyak

I myself am interested in the same questions, but I am going to apply the answers to the RT-N16 + enthusiast firmware. In addition to crooked hands, my speed and stability (!) are influenced by good neighbors, evenly spread over the air, and not leaving a single free channel. I found this out with the help of the inssider software. You have not tried to scan the air, maybe you should first select another channel? Or is this problem already solved?

The preamble is used to communicate to the receiver that data is on its way. Technically speaking, it is the first portion of the Physical Layer Convergence Protocol/Procedure (PLCP) Protocol Data Unit (PDU). The preamble allows the receiver to acquire the wireless signal and synchronize itself with the transmitter. A header is the remaining portion and contains additional information identifying the modulation scheme, transmission rate and length of time to transmit an entire data frame.
Long Preamble:
* Compatible with legacy IEEE* 802.11 systems operating at 1 and 2 Mbps (Megabits per second)
* PLCP with long preamble is transmitted at 1 Mbps regardless of transmit rate of data frames
* Total Long Preamble transfer time is a constant at 192 usec (microseconds)
Short Preamble:
* Not compatible with legacy IEEE 802.11 systems operating at 1 and 2 Mbps
* PLCP with short preamble: Preamble is transmitted at 1 Mbps and header at 2 Mbps
* Total Short Preamble transfer time is a constant at 96 usec (microseconds
Most access points (AP) and broadband Wi-Fi routers are configured for a Long Preamble or have a setting that automatically detects the preamble and adjusts accordingly. A majority of client Wi-Fi adapters should also be pre-configured in the same manner. This is done as a precautionary measure for networks that may still employ legacy devices. It is not recommended you make changes to default settings. If this becomes necessary, consult with your equipment manufacturer before taking such action.
