In this guide we'll show you some tips to troubleshoot your network to make the best work possible for Wireless N.1. Confirm that you are using the new adapterIf you just thaty good for most of 54Mbps or lower, first check to see if you are using a wireless N adapter instead of an older wireless G card or not.
The old adapter can connect with the new N devices, but the speed and efficiency can be achieved only on the connections between a wireless N router or access point (AP) with a wireless adapter N. In short, you must upgrade all wireless devices.
2. Verify that hardware from the same manufacturer
One reason why Wi-Fi Alliance certification for wireless products is to ensure that the development of manufacturing equipment can work together.
However there are some features of the ownership and use must be compatible with its equipment. In addition, there are many issues operational capability between devices over wireless devices N.
While the official standard, but not completed, the company is still issuing Draft products. At this point: You should use the same manufacturer for all network devices to avoid potential problems.
If you have not chosen a brand, think of any specific wireless device that you can or want. For example, if you want to convey the same set of images, video and music files from your computer to your TV with a wireless media extender, you can compare facilities among other brands each other. So you can choose the brand best for you.
As with a certain company, you should look for product reviews online. Just type the model number into Google, you can see a long list of product reviews.
Compare two or three reviews to find out the characteristics of the router that people like or dislike.
3. Just use WPA2 encryption options
N wireless standard does not support WEP, so the connection is encrypted using this model will be limited to devices such as wireless G (54Mbps), even when using the device N.
In addition, the WPA version also does not provide good performance for multi-network N. Therefore, you should use WPA2 encryption (with AES), personal or enterprise.
If you're still using an old adapter only supports WEP, check the manufacturer's website to see if any driver does not upgrade, besides that you should make sure that Windows has been updated in a timely manner.
If that does not help you, advice for you is to buy a new wireless card.
To change the encryption settings, log into the router's configuration utility by typing its IP address into your browser.
The default IP and password will be listed in the accompanying documentation. Then you should find the wireless settings and change the encoding.
4. Change default bandwidth to achieve high speed
If you discover that his speed never exceeds 130Mbps, then you must change the default channel bandwidth. To limit interference with other Wi-Fi equipment that old, N wireless router and the AP was released to establish channels with 20MHz bandwidth.
One way to increase the performance of wireless N is moving up 40MHz bandwidth, this is called multiplexing. Thus the speed of the channel to double, you must change this default setting.
To change the encryption settings, you log into the router's configuration utility by entering its IP address into your browser.
IP and the default password will be listed in the accompanying documentation. Then you look to the wireless settings and change the encoding.
To enable channel bonding, open a browser and type the IP address of the router to login to add its configuration. Then find the wireless settings and select the 40MHz channel width.
Do not forget to save changes before you exit the configuration utility.
5. Disconnected clients Wireless G for best performance
Wireless N is backward compatible with Wireless G devices, even the B standard in the past. However, network traffic will be different when the old adapter is connected to the network N.
This has a negative effect on the speed and performance. So if you do not want any restrictions on data rates and throughput, please ensure that your network has connections with wireless clients N.
You can restrict a client through the router to only allow wireless connections N.
If you want to make this limitation, you log into the router's configuration utility and change the settings in the wireless.
If you still want to support the client wireless B / G, please consider using the old wireless G router or AP.
You can plug the wireless G router to router or AP. Ensure that each router must be set in overlapping channels: 1, 6, or 11, or 11 if only one and use channel bonding on the router N.
Then make sure you only allow N connections on the new router or wireless type indicator in the network name (SSID), so users will know the type of device they are connected to.
6. Use only 40MHz wide channels with strong signals
As mentioned above, to get connection speeds above 130Mbps Wireless N devices, you must double the bandwidth of the channel from 20 to 40MHz.
However, you should review to the multiplex, if not all users have a good signal because this could negatively impact the client has a weak signal.
7. Interference check
As well as wireless G network, you need to consider interference issues, such as neighboring APs are being set up at a certain channel interference or if interference can come from devices radio and other electronics.
But even a wireless N other issues for you. Remember, if you change the default channel bandwidth from 20 to 40MHz (to get higher speeds), it will double the frequency range of your transmission.
If you use the multiplex, you're limited to using two of the three channels do not typically overlap. So you should ensure that you are using channel 1 or 11 on all AP.
Add to that the radio check to see if the network somewhere in the region and select the channel that is not appropriate.
