Hello
I accidentally bought two TP-Link TL-WN821N v2 (accidentally because I
was going for v3). I've tried using them with compat-wireless (just now
tested with 2011-06-15) & the carl9170-driver.
When using these to connect to my Ubiquiti Power AP-N I get terrible
performance. Using another computer with some Broadcom 802.11g chip (b43
driver) it works OK.
For example, doing a 100 packet ping towards my LAN gateway and at the
same time trying to load a webpage.
--- 10.0.0.254 ping statistics ---
100 packets transmitted, 60 received, 40% packet loss, time 99229ms
rtt min/avg/max/mdev = 0.832/93.193/1264.009/292.193 ms, pipe 2
wlan0 IEEE 802.11bgn ESSID:"POWERAPN"
Mode:Managed Frequency:2.427 GHz Access Point:
00:15:6D:9E:D2:A0
Bit Rate=58.5 Mb/s Tx-Power=20 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
Link Quality=64/70 Signal level=-46 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:4 Invalid misc:0 Missed beacon:0
Being closer to the AP with better link quality doesn't help at all.
Should I just get some other USB adapter or is there hope for the ones
that I have? If other, which ones are best supported? I really don't
care about GPL firmware, I just want stable & fast 802.11n performance.
