![]() By default, this uses your device's onboard wireless adapter and the wlan0 interface. ![]() Pay special attention to those that are excellent choices for 5 GHz AP mode, if thisĪfter installing RaspAP your device will broadcast an 802.11g 2.4 GHz access point with the SSID raspap-webgui. You may also wish to skip directly to this short list of "superstar" USB WiFi adapters for Linux. These will work out of the box on Debian-based devices without ![]() We strongly recommend this resource which lists USB WiFi adapters with in-kernel Linux drivers. For example, if you wish to use a Raspberry Pi 4's 802.11ac 5 GHz wireless mode, make sure your adpater also supports this mode. You should also pair an adapter with the wireless mode you intend to operate from your device's onboard wireless chipset. If "AP" does not appear in the list above, save yourself some time and find another adapter. To determine if your USB WiFi adapter is capable of hosting an AP, execute the following: $ iw list Many do not have support for AP mode, require a powered USB hub, manual driver and/or firmware installation or are otherwise not well suited for this application. Your choice of adapter is important external WiFi adapters (ie, "dongles") vary greatly in terms of hardware capabilities and driver support. Connect a USB WiFi dongleīegin by connecting an external wireless adapter to a USB port on your device. Refer to the diagram above as we walk through the steps of creating this configuration. We will create this setup with a WiFi-capable Raspberry Pi (or similar device) and an external USB wireless adapter, or dongle. In practice, you can expect half the bandwidth as a non-boosted signal, as each packet must go over the air twice. The repeater must accept incoming and outgoing packets from clients and forward those packets on to the next WiFi router and accept replies. This is because WiFi is a half-duplex system, meaning only one device may transmit data at any given time. NoteĪ wireless repeater will restrict your maximum throughput. It then transfers the signal to the other wireless router, which retransmits the boosted signal. One of these wireless routers picks up the existing WiFi network. A repeater effectively contains two wireless routers and a minimum of two antennas. ![]() With this arrangment you can effectively double the coverage area of your WiFi network reaching far corners of your home or office, different floors, or even extend coverage outside to a yard or garage. How a WiFi repeater worksĪ WiFi repeater receives an existing WiFi signal, amplifies it and then transmits the boosted signal. This step-by-step walkthrough will assist you in creating this configuration. Often known as a wireless repeater, this setup is particularly useful if you areĮxperiencing problems with "dead spots" in your WiFi network. A popular use case for RaspAP is to connect to your wireless network and rebroadcast an existing wireless signal. ![]()
