For simple, low-throughput tasks like sending emails, browsing the web, or scanning barcodes, dBm is a good signal strength. Minimum signal strength for basic connectivity. Packet delivery may be unreliable. Pauline Charrier Beginner. Should I enable WMM? While WMM is, indeed, designed to give priority to multimedia traffic, it is also required in order to use the high throughput link rates.

When WMM is disabled , only 54 Mbps is possible. Therefore, you must leave WMM on. Gerard Uhtomsky Beginner. How can I boost my 2. Method 1 Using General Tips. Know your router's maximum range. Remove obstructions from your router's path.

The lower this value, theoretically, the greater number of clients that can connect, especially those at greater distances from the base station. At the opposite end, the higher this number, only those wireless clients that can achieve the higher throughput value will be able to connect. Sign up to join this community.

In fact, having a high multicast rate set for a household with just one computer can actually negatively impact performance.

Since the multicast will be using bandwidth, this will be taking bandwidth away from the device, leading to lags and slower speeds. If you have just one device, you can simply use the auto settings found on your router without having to troubleshoot.

However, if you do notice issues with your connectivity or speeds, you might want to evaluate changing your multicast rate. Whether you need a higher or lower multicast rate, the best option is to choose the lowest rates for your needs to prevent interference. As mentioned, a rate that is too low will result in multiple collisions, while higher rates will use up bandwidth and can hinder performance.

The first thing you need to evaluate before determining your ideal multicast rate is how many devices you use on your network. If you have a dense network with so many connected devices this will increase capacity of the network by freeing up overhead. However if you game or use VOIP its best to leave this off. Also turn it off if you have strong signal or fewer then about devices. Some guides say 3 but with the spectrum efficiency of Ever wonder why your skype or games lag on a public network.

BINGO this setting affects it and its actually a good thing because it is to a certain degree allowing to use the wifi network with minimal issues involving congestion. Isolates all devices from crosstalking with one another. Simple as that. Do not turn it on in a home environment. Its best used in a public network as a security mechanism. Enough said. An IP Flood is a type of Denial of Service attack wherein the system is flooded with information thereby using up all available bandwidth further preventing legitimate users from access.

Basically, one device could say fuck you all the bandwidth is mine and usually, this is done to isolate the network and a few computers the attacker may maliciously acquire as its target. When IP Flood Detection is enabled, your router has the ability to block malicious devices that are attempting to flood devices. For example, if you have 1 device that is outside the range of your router, having lower multicast rate WILL NOT extend the wireless range of your router.

It can however affect the useful range in subtle ways. Second off, the multicast rate WILL NOT affect the noise floor or how the router deals with interference, your wireless signal strength, quality, maximum speed, minimum speed, or pretty much everything else you see out there on home made Wikis and Forums.

Changing multicast setting will not affect any of those wireless network characteristics. I think I have beat the dead horse long enough. This is what multicast rate does, IT CAN improve the overall performance of your network when used in the right manor. The same is true in reverse. These are however the edge of the network cases. This setting at the core is part of the IP Multicast datagram. It groups together really big amounts of transmissions and codes in what part of the data goes to which device.

Its almost like multiplexing. Its a point to multipoint transmission type allowing one-to-many or many-to-many realtime communication over a wifi network. Its used to improve overall efficiency. This tranmission type falls between unicast and broadcast. Uni going to one device from one place. Broadcast is one to all and Multi is one to some or many. Hence, rather than sending thousands of copies of a stream, the server instead streams a single flow that is then directed by routers on the network to the hosts that have specified that they need to get the stream.

This removes the requirement to send redundant traffic over the network and also be likely to reduce CPU load on systems, which are not using the multicast system, yielding important enhancement to efficiency for both server and network.

Where is the relation? Well the rate to do this is significantly lower then the rest of the networks unicast rate. This can be in upwards of gigabits. The multicast however requires processing and modultion and certain headers and simultaneous communication so the network has to slow down to a synchronized rate on the wifi network This differs from internet and wired multicast. To optimize this setting you should disable IGMP Snooping and set the multicast rate to be fixed at the lowest value possible setting.

Some routers have the lowest value as 1mb, 2mb, or 5mb with the appropriate modulation setting automatically being used. Here are two setups: say your router is located in your living room and a You have a single laptop in your bedroom. In this case, the scenario b will benefit from higher multicast setting which will require higher modulation LOWERING the overall effective range of your network.

However, too high of a multicast rate can hinder the performance of your laptop inside the bedroom, as the multicast will take away the available bandwidth measured in mbps. The only time you should optimize and test different multicast rate settings is when you run multiple streaming devices simultaneously in your home. Long or Short no texans bigger is not better and no anime fans the loli short part of the setting isnt better either. It highly depends on your network setup.

So what is preamble? Once again its another error checking setting however the preamble has to do with channel aging and pilot tones. Long has 8 and Short has 4. It gives us the characteristics of the channel we are transmitting on. There are alot of these and to understand why so many are needed a wireless setting will require expansion on the theory side of this stuff.

It adds some additional data headers to check for wifi data transmission errors. Short Preambles uses shorter data strings that are in use for error checking which means that it can and usually is much faster than a long type preamble and has less overhead.
