You can find the first useful devices with sufficient system specifications around 5-10 USD, if you'r patient - with new (low-end-) devices starting around 20 USD, either of these will do a much better job, better performance, better reliability, no fuzz. With unmatched wireless performance, reception, and security protection, the TL-WN721N/TL-WN722N/TL-WN821N is the best choice for easily adding or upgrading wireless connectivity to your desktop. Any ~decade old OpenWrt supported lowest-end router/ AP can do a massively better job than any USB wireless card, these simply haven't been designed for these tasks (and accordingly their firmware isn't battle-tested for these purposes, which shows).ĭo yourself a favour, skip USB wireless and get a second hand/ cheap ath9k (PCI/ AHB) based (or better) wireless router/ AP capable of running OpenWrt, even if you use them as repeater on the same radio the results will be considerably better than ar9271 or any USB wireless card. through the installation process and the TP-LINK Wireless Configuration Utility instructing you to quickly set up a wireless connection.

I've tried to use ar9271 (in form of a rev 1.0 or 1.1 tl-wn721n) as a second 2.4 GHz radio in AP mode on a tl-wdr4300 for a few years in the past - yes, it kind of 'works', but performance and especially reliability were 'not good™' (to keep it PG13)… Expect stalled connections, client not being able to reconnect, huge delays, it's not pretty. Additionally the on-device RAM of ar9271 is very limited, allowing only a limited number of clients to connect to it in AP mode (4-8) this is a physical limit that can't be extended in software.

An included CD with utility helps you complete the software installation and wireless network setup.To be clear, ar9271 is one of the best supported (in the sense of ath9k_htc) USB wireless cards existing, but it still doesn't work acceptably well as AP or in 24/7 operations no USB wireless card does. Driver Name, TP-Link TL-WN721N Driver Info, Hardware ID: USB VID0CF3 & PID9271 Protocol Standards IEEE 802.11g, IEEE 802.11b. This is not only faster than normal security setups, but also more convenient in that you don't need to remember a password. Just press the "QSS" button and you will automatically establish a WPA2 secure connection. As for security, the adapter provides WPA/WPA2 encryptions that are created by the WI-FI Alliance industry group, promoting interpretability and security for WLAN, more effectively and efficiently protecting the wireless network than a WEP encryption.Ĭompatible with WI-FI Protected Setup (WPS), this adapter features Quick Security Setup that allows you to almost instantly setup your security. This adapter demonstrates an excellent ability to curb data loss over long distances and through obstacles in a small office or a large apartment-even in a steel-and-concrete building! You can easily pick up the wireless network during long-distance connection, where legacy 11g wireless products may not be able to do so.Ĭlear Channel Assessment (CCA) technology automatically avoids channel conflicts using its clear channel selection feature, and fully realizes the advantages of channel binding, greatly enhancing wireless performance. Compliant with IEEE 802.11n, it provides wireless speeds up to 150 Mbps, which is great for online gaming or video streaming. The TP Link 150 Mbps Wireless N USB Adapter allows you to connect a desktop or notebook computer to a wireless network and access a high-speed Internet connection.
