Tenda Wifi Usb Driver 802.11 N Wlan Free Download

[Rosette Allaband]

obviouslyi have not been sending the promised log. but i come across another point that maybe solves the problem. i have heard that when i know the chipset version i can download and install a driver that support exactly this chipset version, so that the wlan stick is recognized.

Configuring wireless is a two-part process; the first part is to identify and ensure the correct driver for your wireless device is installed (they are available on the installation media, but often have to be installed explicitly), and to configure the interface. The second is choosing a method of managing wireless connections. This article covers both parts, and provides additional links to wireless management tools.

The #iw section describes how to manually manage your wireless network interface / your wireless LANs using iw. The Network configuration#Network managers section describes several programs that can be used to automatically manage your wireless interface, some of which include a GUI and all of which include support for network profiles (useful when frequently switching wireless networks, like with laptops).

The default Arch Linux kernel is modular, meaning many of the drivers for machine hardware reside on the hard drive and are available as modules. At boot, udev takes an inventory of your hardware and loads appropriate modules (drivers) for your corresponding hardware, which will in turn allow creation of a network interface.

Some wireless chipsets also require firmware, in addition to a corresponding driver. Many firmware images are provided by the linux-firmware package; however, proprietary firmware images are not included and have to be installed separately. This is described in #Installing driver/firmware.

To check if the driver for your card has been loaded, check the output of the lspci -k or lsusb --verbose command, depending on if the card is connected by PCI(e) or USB. You should see that some kernel driver is in use, for example:

Also check the output of the ip link command to see if a wireless interface was created; usually the naming of the wireless network interfaces starts with the letters "wl", e.g. wlan0 or wlp2s0. Then bring the interface up with:

If your wireless card is listed above, follow the #Troubleshooting drivers and firmware subsection of this page, which contains information about installing drivers and firmware of some specific wireless cards. Then check the driver status again.

Managing a wireless connection can be accomplished using network manager which will use wpa_supplicant or iwd for wireless authentication, or using wpa_supplicant or iwd directly. For lower level configuring, or if you are using a legacy driver or a legacy authentication method, there are iw and the deprecated wireless_tools.

You can authenticate to WPA2 Personal networks using wpa_supplicant or iwd, or connect using a network manager. If you only authenticated to the network, then to have a fully functional connection, you will still need to assign the IP address(es) and routes either manually or using a DHCP client.

WPA2 Enterprise is a mode of Wi-Fi Protected Access. It provides better security and key management than WPA2 Personal, and supports other enterprise-type functionality, such as VLANs and NAP. However, it requires an external authentication server, called RADIUS server, to handle the authentication of users. This is in contrast to Personal mode which does not require anything beyond the wireless router or access points (APs), and uses a single passphrase or password for all users.

The Enterprise mode enables users to log onto the Wi-Fi network with a username and password and/or a digital certificate. Since each user has a dynamic and unique encryption key, it also helps to prevent user-to-user snooping on the wireless network, and improves encryption strength.

This section describes the configuration of network clients to connect to a wireless access point with WPA2 Enterprise mode. See Software access point#RADIUS for information on setting up an access point itself.

WPA2-Enterprise wireless networks demanding MSCHAPv2 type-2 authentication with PEAP sometimes require pptpclient in addition to the stock ppp package. netctl seems to work out of the box without ppp-mppe, however. In either case, usage of MSCHAPv2 is discouraged as it is highly vulnerable, although using another method is usually not an option.

The regulatory domain, or "regdomain", is used to reconfigure wireless drivers to make sure that wireless hardware usage complies with local laws set by the FCC, ETSI and other organizations. Regdomains use ISO 3166-1 alpha-2 country codes. For example, the regdomain of the United States would be "US", China would be "CN", etc.

Regdomains affect the availability of wireless channels. In the 2.4GHz band, the allowed channels are 1-11 for the US, 1-14 for Japan, and 1-13 for most of the rest of the world. In the 5GHz band, the rules for allowed channels are much more complex. In either case, consult this list of WLAN channels for more detailed information.

Regdomains also affect the limit on the effective isotropic radiated power (EIRP) from wireless devices. This is derived from transmit power/"tx power", and is measured in dBm/mBm (1dBm=100mBm) or mW (log scale). In the 2.4GHz band, the maximum is 30dBm in the US and Canada, 20dBm in most of Europe, and 20dBm-30dBm for the rest of the world. In the 5GHz band, maximums are usually lower. Consult the wireless-regdb for more detailed information (EIRP dBm values are in the second set of brackets for each line).

Misconfiguring the regdomain can be useful - for example, by allowing use of an unused channel when other channels are crowded, or by allowing an increase in tx power to widen transmitter range. However, this is not recommended as it could break local laws and cause interference with other radio devices.

However, setting the regdomain may not alter your settings. Some devices have a regdomain set in firmware/EEPROM, which dictates the limits of the device, meaning that setting regdomain in software can only increase restrictions, not decrease them. For example, a CN device could be set in software to the US regdomain, but because CN has an EIRP maximum of 20dBm, the device will not be able to transmit at the US maximum of 30dBm.

It is also possible to configure the cfg80211 kernel module to use a specific regdomain by adding, for example, options cfg80211 ieee80211_regdom=JP as module options. The module option is inherited from the old regulatory implementation and in modern kernels act as a userspace regulatory hint as if it came through nl80211 through utilities like iw and wpa_supplicant.

Hardware buttons to toggle wireless cards are handled by a vendor specific kernel module. Frequently, these are WMI modules. Particularly for very new hardware models, it happens that the model is not fully supported in the latest stable kernel yet. In this case, it often helps to search the kernel bug tracker for information and report the model to the maintainer of the respective vendor kernel module, if it has not happened already.

If you have problematic hardware and need internet access to, for example, download some software or get help in forums, you can make use of Android's built-in feature for internet sharing via USB cable. See Android tethering#USB tethering for more information.

A good first measure to troubleshoot is to analyze the system's logfiles first. In order not to manually parse through them all, it can help to open a second terminal/console window and watch the kernels messages with

If you are on a public wireless network that may have a captive portal, make sure to query an HTTP page (not an HTTPS page) from your web browser, as some captive portals only redirect HTTP.If this is not the issue, check if you can resolve domain names, it may be necessary to use the DNS server advertised via DHCP.

Wireless hardware disables RTS and fragmentation by default. These are two different methods of increasing throughput at the expense of bandwidth (i.e. reliability at the expense of speed). These are useful in environments with wireless noise or many adjacent access points, which may create interference leading to timeouts or failing connections.

Packet fragmentation improves throughput by splitting up packets with size exceeding the fragmentation threshold. The maximum value (2346) effectively disables fragmentation since no packet can exceed it. The minimum value (256) maximizes throughput, but may carry a significant bandwidth cost.

RTS improves throughput by performing a handshake with the access point before transmitting packets with size exceeding the RTS threshold. The maximum threshold (2347) effectively disables RTS since no packet can exceed it. The minimum threshold (0) enables RTS for all packets, which is probably excessive for most situations.

If your journal says wlan0: deauthenticating from MAC by local choice (reason=3) and you lose your Wi-Fi connection, it is likely that you have a bit too aggressive power-saving on your Wi-Fi card. Try disabling the wireless card's power saving features (specify off instead of on).

On some laptop models with hardware rfkill switches (e.g., Thinkpad X200 series), due to wear or bad design, the switch (or its connection to the mainboard) might become loose over time resulting in seemingly random hardblocks/disconnects when you accidentally touch the switch or move the laptop.There is no software solution to this, unless your switch is electrical and the BIOS offers the option to disable the switch.If your switch is mechanical (and most are), there are lots of possible solutions, most of which aim to disable the switch: Soldering the contact point on the mainboard/wifi-card, gluing or blocking the switch, using a screw nut to tighten the switch or removing it altogether.

Another cause for frequent disconnects or a complete failure to connect may also be a sub-standard router, incomplete settings of the router, interference by other wireless devices or low quality signal.
