Re: [beagleboard] Re: Wifi unreliable
Small update, I got the TL-WN722N to work. Since yesterday evening it is online, hope it will stay that way. The biggest problem was that wlan0 was already taken from the old dongle, so it now runs on wlan3. first I followed this instructions: (not sure if I had to :)) https://wiki.debian.org/ath9k_htc Then I had some problems that I would see wlan3 in iwconfig, but wicd-curses would not be able to access it (added wlan3 in prefs) I think adding wlan3 to /etc/network/interfaces did the trick for me. thanks for all the suggestions, I think I am now happy (until the next problem...)

[beagleboard] Re: Wifi unreliable
@Tommi - I have a similar setup and use a variety of 80211 usb plugs via a usb hub and external power source. One is a Realtek RTL8188CUS using the RTL8192cu driver (the plug you use is a true RTL8192cu.) Ideas: * Receive Signal Strength (RSS) plays a big part and can vary dramatically by location and plug. If it's below -60dB you will drop packets, below -70dB and it gets bad. Yes, TCP is a reliable protocol but I've found that some plugs just stop when the noise level is too high. I run WPA2 and I suspect the plug will loose connection and then cannot re-negotiate a good eapol exchange when reconnecting - dead in the water at that point. * To get signal strength 1) install iw and use iw dev wlanX link or 2) use sudo wpa-cli -y -n0 -p strength. Option 2 is less reliable than 1. * The Ralink RT537 and RTL8187 plugs seem to perform better. Try another device/driver combination, maybe will work better for you. * The Atheros chipsets are suppose to be great; the post mentioned about Ubuntu supports them but Debian not so much. I'm thinking of switching to Ubuntu just because I run that on my other systems. I don't know why I haven't tried the Atheros plugs - maybe cost?

thanks for your replies. I just ordered a different USB plug, let's see if that improves things. After tinkering so much with it, it seems the better options.

@Tommi, We had similar problems with RTL8192/Realtek dongles. We moved to TP-LINK 722 and so far its been super! We've tested streaming video for over 2 weeks with it now.

Hi Tommi, The only way I could do it was follow this post: http://beagleboard.org/Community/Forums?place=msg%2Fbeagleboard%2F9KCIs7yqsa8%2FThUHYh8KQzgJ On Sunday, November 30, 2014 10:46:17 AM UTC+11, Tommi wrote: Hey everyone, I have been using the BBB now for quite a while and I really like it. There is only one persistent problem I do not seem to get rid of. So I hope you can guide me into the right direction. I am using the Ourlink wifi dongle https://www.adafruit.com/products/1012 to connect to the internet and wicd-curses to set up the wifi. Initially it seems to work fine. However, quite often the dongle disconnects and I am no longer connected to the internet. I am unsure how to proceed or what I could try. A couple of observations/comments: - I am using an external usb hub http://www.amazon.com/dp/B005A0B3FG/ref=pe_385040_121528360_TE_dp_1 and the beaglebone is also powered from a 5V wall plug https://www.adafruit.com/products/276. So sketchy power supply should not be the issue as some people indicate. - Interestingly wicd-curses still indicates that it is connected, however the router does not confirm that and I cannot connect to the BBB. - It seems to happen more often when I try to run BTSync to push a lot of data through the BBB to an external HDD. If it sits just there and idles it can be online for days without problem. Do you guys have any advice what to try? I am quite lost and the internet does not give me any more help... Thanks!
