GtownKY,

I would also like to know how the TP-LINK TL-WDN3200 worked,

Thanks!

Re: 5ghz wifi adapter?

I bought the TP-Link WDN3200 usb 2.4/5Ghz adapter.

Works right out of the box both with RPi2 with Raspbian and RPi B with OSMC (both at 2.4 GHz and 5 GHz), but apparently needs a powered USB hub on RPi B as sometimes the RPi B hangs (but worked on an USB port on RPi2 with 2A power supply without powered USB hub need)

BUT!!!!!, on 5GHz it only appears to connect at just 6Mb/s as this shows....

Code: Select all

wlan1     IEEE 802.11abgn  ESSID:"my_5GHz_net"
          Mode:Managed  Frequency:5.805 GHz  Access Point: A0:F3:C1:86:3E:3B
          Bit Rate=6 Mb/s   Tx-Power=20 dBm
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=70/70  Signal level=-40 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:83   Missed beacon:0
and iwlist shows...

                              36 Mb/s; 48 Mb/s; 54 Mb/s
                    Mode:Master
So... why only 6Mb/s on the first case and why only up to 54Mb/s on the second? Shouldn't I get around 300Mb/s values?
The RPi2 is placed just half meter away from the router!!!

Any ideas?

Thanks,
Pablo

I just stumbled upon this project I want to do with wireless multiroom audio so without knowing much about the raspberry pi, based on the speeds you reported, you are only connecting at 5ghz wireless-A and 2.4ghz wireless-G. That is my best guess as to why you cannot connect at faster speeds.
5ghz is A,N,AC while 2.4ghz is B,G,N with the respective top speeds at 6,300,1800* and 12*,54,300 (mbps) *I wasn't sure about top speeds of B or AC

Sounds possible. Is there any way (command line, or something) to check wich mode I'm connected to?

The TL-WDN3200 works great on my RPi2, $10 refurb NewEgg. Had it connected to my Belkin F7D8302 (Tomato) in minutes on 5Ghz, with 8MBps test both ways in iperf. I use a HiFiBerry Amp+ with a big 12V brick so I don't know if it might need extra power for others.

Tl-wdn3200 (rt5572) works in 5GHz managed mode, hostapd master mode and in monitor mode on RPi2 with the firmware-linux-nonfree package. You may also need to set the wireless regulatory domain with

/etc/hostapd/hostapd.conf

I can confirm this. I got this wireless dongle from ebay http://www.ebay.com/itm/201456402478 with same chipset and managed to get it running in OpenWrt on the Pi as an access point (5GHz, channel 40) :-)

Initialy I had same problem as person here https://forum.openwrt.org/viewtopic.php ... 00#p249000 and got the "Wireless is disabled or not associated" message in Luci when changing from 2.4GHz to 5GHz but manual fix of /etc/config/wireless and setting mode to '11na' from '11n' like described here https://forum.openwrt.org/viewtopic.php ... 28#p255028 fixed the issue.

It also seems to work just fine in raspbian as a client and joins 2.4GHz network. I ordered another one to be able to test it both as AP and a client together.

Re: 5ghz wifi adapter?

Pablo,

If you are still reading this forum, your adaptor is only connecting at the legacy 802.11a/g rates and not the 802.11n/ac rates (a.k.a. Modulation Coding Scheme or MCS rates) because the MCS rates require your nic to support both WMM for QoS and either AES encryption (when using a pre-shared key or 802.1X authentication) or an open authentication with no encryption. Without either of these, you will not get MCS rates. I'm assuming either the drivers on the RPI out of the box had some of these features disabled or you need to modify the config on your SSID/AP. Additionally, you will not get the full 300 Mbps (or faster with 11ac) unless you have enabled minimum 40 MHZ channel bonding and short guard intervals on your AP. Otherwise you'll cap out at around 144 Mbps. Hope this helps you get more speed out of your nic.

Hi Paul & Lyman....or anyone...could you please furnished with parameters required to modify to bring up wifi with 5GHz band?? Parameters like channel, hw_mode or anything. I am using TL WDN3200 and could able to bring up wifi for 2.5 GHz band using hostapd utility.

Hi, I have tried given parameters. It seems channel number not valid for AP mode (don't remember exact error statement). I tried `iw get reg` n that shows country code 00. I could not able to set using `id set reg US`.
do i need to provide country_code=US as one of the parameter? will that work or need to try anything else?

Hi,
I could able to find out the issue....it seems problem is "no IR" flag marked for the channels comes under Band 5GHz. To remove the flag (stop passive scanning) I have made couple of changes as suggested in link below (modified regd.c with a patch). but still i could see the "no IR" flag enabled. Any idea??

Finally, I could able to bring up wifi at 5GHz frequency band using TP-LNIK TL-WDN3200 dongle. I have install the crda and update the regulatory domain using `iw` utility. Further I verified the frequency band status using `iw list` and this time 5GHz mapped channels were present without "NO IR" flag.

Re: 5ghz wifi adapter?

I posted over a year ago in this thread asking about the TP-LINK TL-WDN3200. At the time I was trying to get a Rosewill RNX-600UB to work. I was never able to get a stable AP functioning in the 5 GHz band, so I abandoned the project.

Now I'm again searching for a 5 GHz USB adapter with Linux support, and it seems like the situation has only become worse. It seems odd since 802.11ac requires 5 GHz, yet people are still recommending the TP-LINK TL-WDN3200 which came out years ago. It is long gone, except for scalpers selling for over $100 each. I thought NewEgg's listing for the TL-WDN3200 was amusing - a price of $9999.00 (plus shipping of course!)

So has anyone found any other workable 5 GHz USB adapter supported on the Raspberry Pi?

The Asus specs page does not indicate that the USB-N10 NANO has any 5 GHz capability. It appears to be 2.4 GHz only. Did you mean a different device?

I'm really interested in finding a 5ghz and 802.11ac chipset that works OTB with the pi too (and preferably, can be used to be an access point on the pi..)

Hi

Were you able to use your RaspPi to connect to a 5GHz Wi-Fi network? If yes, can you please share the details? I'm working on a project which has the exact same requirement.


Thanks

I have found this device to work natively with 5ghz support.

Thanks for posting your finding. It appears to be entirely generic. No manufacturer, no model number. I'd prefer to buy from a North American supplier like Amazon or NewEgg, or even Ebay, but I have no idea what to search for. "Ralink RT5572" is the only clue.

It could be this, or there is a long list of adapters here.

Given the appearance and chipset, I suspect this adapter is similar to or identical to the TP-LINK TL-WDN3200 that I discussed earlier in this thread. The issue is while it might work as a client at 5 GHz, it is not possible to use the TL-WDN3200 (and likely any adapter based on the Ralink RT5572) as a stable 5 GHz AP with hostapd.

The Ralink RT5572 is the prior generation of chipset (802.11n, as compared to current generation 802.1ac chipsets). According to the Wiki, products with this chipset were developed from 2011 through 2016. That may be the only option for the Pi/Linux platform, though.
