Recommend a WLAN USB adapter

nawitus · 2012-06-25 20:42:51

Hi, can someone recommend a wlan USB adapter which supports 802.11n and has at least 2 antennas for 2x2:2 MIMO? It should also have open source / free software drivers (no ndiswrapper stuff). I already have an integrated wlan card, but it only has 1 antenna, so the speed is only 40-50 Mbps which is too slow. For reference, here's (a Finnish) website listing some suitable wlan adapters, but I don't know whether or not they work well and quickly on Linux. It's difficult to find information whether or not those cards support fast speeds and multiple antennas online. I don't want to buy an wlan adapter and find out it's just as fast as my integrated one.

Have you searched the forums? There are a couple of threads on this. TP-Link 821N is one that works and uses ath5k module from the kernel. No other drivers needed. For the rest you can search the forums.

Thank you, I'll guess I'll get that one then.

If you haven't bought an adapter yet you can check out my post above.

I bought TP-Link 821N, and the network connection hangs/stops working after 1-2 minutes of torrent download. I can fix the connection only by rebooting. By "connection hangs" I mean that connection completely stops working.

The speed tests showed 60 Mbps though, which is pretty good. I'm using linux 3.2.13-1. The wlan adapter uses ath9k_htc, not ath5k as suggested earlier. Should I try ath5k? ath9k_htc is for 802.11n according to the wiki.

Not updated, because of unrelated problem with ALSA. I might try updating later though.

I updated to linux 3.4.4-2 now, and the problem persists.
