Anthony, thank you so much for all your work - it's extremely helpful. Unfortunately, I see the same:
Failed to create interface mon.wlan1: -95 (Operation not supported)
wlan1: Could not connect to kernel driver
error message that nulldev reported. After that message appears, I can connect to the RPi3 as an access point, but it no longer connects to the local WiFi network. I've run your steps on a fresh install of Raspbian Jessie 2016-3-18, and the result is the same.
Any thoughts you might have as to what might be causing the problem, and why your (and stopgaplabs') RPi3 are behaving differently from mine and nulldev's would be greatly appreciated.

Re: Pi 3 as wiireless client and wireless AP?
Well what is wlan1? None of the instructions mentioned wlan1? Are you making the virtual interface called wlan1 instead of uap0? wlan* are dedicated interfaces for non virtual devices I believe this might be the issue.
Re: Pi 3 as wiireless client and wireless AP?
Oops - sorry - I copied and pasted part of nulldev's reply, and did not notice that it read wlan1 instead of uap0. My error message actually reads:
Failed to create interface mon.uap0: -95 (Operation not supported)
uap0: could not connect to kernel driver
Again, many thanks for any thoughts you might have.

Re: Pi 3 as wiireless client and wireless AP?
Mine says this also, but it works.. It should say AP ENABLED. Perhaps set your channel the same in the hostapd.conf?
So your AP on uap0 and wifi on wlan0 use the same channel.

Re: Pi 3 as wiireless client and wireless AP?
Hi, im new here and im not really sure what i am doing.
I got my first Pi a week ago with the idea that i would make it into a Tor AP that i can use it at home and when im in unsecured WiFi connections like internet cafe's etc. The Pi 3 with its much better hardware and built in Wireless chip made me ecstatic and i payed for it as soon as it was released.
However i have been stuck on this enigma for more than a week than, i have not been able to create an actual AP no matter what guide i followed.
First ones for older Pi 2 were faulty and my Pi couldnt find the nl80211 driver so i tried other one to no avail.
Then i found this guide https://frillip.com/using-your-raspberr ... h-hostapd/
it all went well and i managed to set up the AP but i could not connect to the internet. But after messing around with the IP addresses in the guide i managed to get a VERY slow internet connection that would drop.
Then i found this guide and it went well but again i cant connect to the internet!
Please can someone help on this, im starting to lose my mind here.
Does it matter what IP address i use because many use IP Addresses that are not like my router at home which is 192.168.0.1
Any help would be appreciated.

Re: Pi 3 as wiireless client and wireless AP?
Hey all, been trying to figure this same problem out on my own for a while now and have luckily stumbled into this thread. I've tried a few different suggestions of the thread but none seem to be working for me; most recent one is anthony19114's suggestion, but at the end of it, I get errors saying:
Thanks!
Does anybody seem to have a definitive walkthrough for getting a Pi 3 to connect to the internet with its built-in wifi then broadcast that with a wifi dongle? Or might anybody be able to point me in the right direction or offer some advice?Could not read interface uap0 flags: No such device
nl80211: Driver does not support authentication/association or connect

Hi Anthony! Thanks for the quick response. I don't think that'll do me much good, being that I don't even have a line in my hostapd.conf file for the driver:

Re: Pi 3 as wiireless client and wireless AP?
If your using two wifi cards change uap0 to the interface you want the AP to broadcast on.. This uap0 in the instructions here is for using only the built in wifi with no second wifi card. So perhaps in this tutorial you can replace uap0 with wlan1 in all the configuration and don't use the iw command to make a virtual interface since you have a second physical device.
Re: Pi 3 as wiireless client and wireless AP?
That worked for me up to a point. I am able to connect to wifi via wlan0, and wlan1 is broadcasting my network. I get feedback from the Pi as I connect via my phone. However, it seems like it's unable to connect fully; it only has that spinning circle and my phone displays that it's connected to 4G rather than the wifi.
Also, when I enter:

Re: Pi 3 as wiireless client and wireless AP?
Thanks for the tuto Anthony (AP and station on single chip), it works great!
Next up is the singel channel challenge
As of now I have to define into hostapd.conf the channel to use for the AP. And this channel must be the same as whatever channel of ap the station connects to. This work exactly one out of four times at my home where I run multiple accesspoints with same ssid but different channels to cover the area.
And it will be a problem when I connect to public hotspots as well.
Any idéas on how to work around this.

Re: Pi 3 as wiireless client and wireless AP?
To me it seem a bad idéa to use same ssid on ap and client. This would be to ask for it to connect to self. But what if you try "priority" in the network tags in wpa_supplicant.conf. Higher number gives higher priority.FreshMint wrote:Have you been able to get wpa_supplicant to join OTHER networks AFTER hostapd is up and running with the virtual network?anthony19114 wrote:If anyone experiences network performance issues it can be remedied if you use the same wpa password on AP and virtual interface and/or same channel.

I have the pi3 with Jessie and this isnT working perfectly I have a second Wlandevice with a 5dbi antenna from adafruit.
wlan0 is loosing IP address and once hostapd went sleeping
the powermanagement remains on, on dev uap0.
AND the best it happened, that my correct credentials for wireless were not accepted, because of wrong key.
I thought already maybe I have to use the same key. maybe then it's working better.
I will have a try.

Re: Pi 3 as wiireless client and wireless AP?
Hi, anyone has found a solution to this problem? I have the same issue too. If in hostapd I use a different channel from the one of the access point, nothing works (and the client pc with windows freeze). The raspberry will be used in a roaming configuration, with channel and ssid changing every day. At the moment the only solution I found is to add a usb wifi card.petter.oj.norman wrote:Thanks for the tuto Anthony (AP and station on single chip), it works great!

Re: Pi 3 as wiireless client and wireless AP?
After struggling with this B3 problem for weeks and just about giving up, I found two hints here that were indispensable. One was needing to have both the physical interface WLAN0 and the virtual interface uap0 on the same channel, which seemed counterintuitive until it sunk in that a physical interface could not simultaneously operate on two different channels. The second, a bit more perplexing, is finding WLAN0 would disconnect when uap0 came up, but only when run from rc.local on boot. When hostapdstart was invoked from the command line WLAN0 retained its IP and kept its association with my wireless router. I eventually added a 2 second sleep before invoking hostapd, the last line in that script. I still see a short-lived ad-hoc network with my router's SSID come up before my AP comes up, according to my WLAN monitor app on my phone. I have no idea why that is happening. Anyway, it reliably comes up on boot now and both the eth0 and WLAN0 interfaces are active, and I can access apps running on the AP with or without an internet connection, which is exactly the behavior I wanted. The one thing I would like to add (if it's not there already but I don't know how to use it) is a DHCP client (I think) to make the AP's and other devices' hostnames routable on its subnet instead of having to use IPs. Can anyone point me in the right direction?
Here's my /etc/network/interfaces file. Note I am using the original reference to wpa_supplicant and also note the power save option I added. It seems the on-board interface does go into power save mode by default.

Re: Pi 3 as wiireless client and wireless AP?
I really like the way this is presented and think I am very close, but alas things do not work.
I get a dhcp address from wlan0 on a 192.168.1.0\24 network, set up uap0 and the dnsmasq and hostapd config files.
I set up uap0, get dnsmasq running and ifup uap0 and everything is fine at that point.
When I start hostapd I do get an access point that I can connect to the 192.168.2.0/24 network, but the act of starting hostapd (before even connecting) causes wlan0 to drop its connection to my router effectively isolating my system and whatever is connected to the access point. ifconfig wlan0 shows no inet addr.
I have seen some references to wpa_supplicant bug and some linux bridging bug but I am not sure what to do/where to look.
I am running versions 2.3 of hostapd and wpa_supplicant. and uname -r returns: 4.4.11-v7+
Help would be most appreciated.
thanks

Re: Pi 3 as wiireless client and wireless AP?
Thanks to anthony19114 and everybody else for providing a solution.
I tried anthony's setup verbatim at first, and, as others reported, got access point working, but no connection over wlan0.
As barry914 summed it up, "One was needing to have both the physical interface WLAN0 and the virtual interface uap0 on the same channel". And the wlan0 channel is not something you can control on your Raspberry Pi — this is the channel that your home Wi-Fi router broadcasts on. So in my case, it was channel 8, so after editing channel setting in /etc/hostapd/hostapd.conf to read `channel=8` and rebooting RPi I was able to get both AP and wlan0 working.
So if one wants to somehow automate the process of booting AP and wlan0, they need to boot with AP turned off, wait for wlan0 to connect, get the channel number from `iwlist channel`, update /etc/hostapd/hostapd.conf (or create a temporary config file) and finally run `hostapdstart` script to start AP. If at boot time wlan0 fails to connect to any network, then AP can use any channel.
The logic above can probably be integrated into the hostapdstart script itself. Hope this helps.

Re: Pi 3 as wiireless client and wireless AP?
Hi,
I have been running into some issues with this setup. I have my rp3 setup as earlier outlined. The built in wifi is running as a client on my home network and running as an 'ap'.
I can connect to the ap with my laptop.
I also have apache running on the rp3. I can access webpages I have hosted the rp3 by connecting to the ap with my laptop and then entering the ipaddress of the ap in the browser followed by the page name.
For example 192.168.2.1/index.html. While connected I can also pass through the rp3 and get to the internet ... www.google.com for example.
While connected I can ssh from the laptop to the rp3. The issue comes up here because my ssh connection keeps seeming to freeze pretty often. I can get maybe one or two commands to complete before it happens. Sometimes it will disconnect completely, . I lose the ssh connection and the connection to the ap over wifi, but sometimes ssh just freezes and then it will resume.. I will be typing, then the putty session stops responding, then it will 'wake up' and the letters I have typed all appear at once.
When it is 'frozen' I can ping it and usually get either 50% or greater dropped packets or 50% of the pings will be in the several hundred ms range.
I have made sure the ap is broadcasting on the same channel as my home wifi I have made the passwords the same, and I have upgraded the kernel.
Any tips on helping troubleshoot this issue would be greatly appreciated. One thing that came to mind was maybe checking that my home wifi and the ap were both using the same flavor of wifi -- 'g' or 'n' ..But I'm not sure that is worth looking at or how to tell which the pie is connecting to my home router through.
Anyone got any ideas on how to troubleshoot this? which logs should I be checking?
Thanks!
I have been running into some issues with this setup. I have my rp3 setup as earlier outlined. The built in wifi is running as a client on my home network and running as an 'ap'.
I can connect to the ap with my laptop.
I also have apache running on the rp3. I can access webpages I have hosted the rp3 by connecting to the ap with my laptop and then entering the ipaddress of the ap in the browser followed by the page name.
For example 192.168.2.1/index.html. While connected I can also pass through the rp3 and get to the internet ... www.google.com for example.
While connected I can ssh from the laptop to the rp3. The issue comes up here because my ssh connection keeps seeming to freeze pretty often. I can get maybe one or two commands to complete before it happens. Sometimes it will disconnect completely, . I lose the ssh connection and the connection to the ap over wifi, but sometimes ssh just freezes and then it will resume.. I will be typing, then the putty session stops responding, then it will 'wake up' and the letters I have typed all appear at once.
When it is 'frozen' I can ping it and usually get either 50% or greater dropped packets or 50% of the pings will be in the several hundred ms range.
I have made sure the ap is broadcasting on the same channel as my home wifi I have made the passwords the same, and I have upgraded the kernel.
Any tips on helping troubleshoot this issue would be greatly appreciated. One thing that came to mind was maybe checking that my home wifi and the ap were both using the same flavor of wifi -- 'g' or 'n' ..But I'm not sure that is worth looking at or how to tell which the pie is connecting to my home router through.

Re: Pi 3 as wiireless client and wireless AP?
I'm not sure this is related, but I have no problem connecting to the AP from my laptop, but my Android phone won't stay connected. It gets an IP, stays connected for a bit and then disconnects. I get an error message that says it received an unknown SSID. I think when the phone gets the router's SSID it freaks out (that's a technical term), but my Windows machine is more robust and can deal with this.
