Hi all, I have started exploring wifi applications of legato. The WiFi client and client test seems to be working fine; but access point is acting up. In both legato command line and test application I can create a discoverable WiFi access point; but when I try to connect with the access point with a device it is remaining at “connecting…” and is not proceeding further. I have set up the etc/dnsmasq.d/wifiAP.conf as specified by the wifiApTest.c. Also while using command line to set up the wifi I execute the commands as specified in [wifi - Legato Docs](http://legato.io/legato-docs/latest/wifi_toolsTarget_wifi.html). I am using a MangOH Green board with wp8548. ---

Hi @codegit001, So you’re trying to connect to the (mangOH) AP from a device (Another mangOH? PC? Smartphone?) and the device shows “Connecting …” ? I wonder if the DHCP server is working properly. What’s the content of {{/etc/dnsmasq.d/wifiAP.conf}}? Is dnsmasq running? With which args? ---

I am trying to connect using my mobile phone. I used logread -f | grep wifi and it says peer didnot ack 100 packets and is disconnecting. I have the logs, but it seems I cannot attach files to my comments yet. From the logs dnsmasq is up and running with the values from wifiAp.conf; which contains: dhcp-range=wlan0,192.168.10.10,192.168.10.199,24h ---

Have you tried with another device? Eventually one where you can set a static IP just to get that out of the way, even though that doesn’t seem to be the problem here. Your `wlan0` ip is something like 129.168.10.1 right? ---

Also BLR-DTDL3P1MXJ2 is the workstation from which the ssh is connecting to the board. Why is that popping up with reference to dnsmasq-dhcp[2369]: DHCPACK(usb0) and dnsmasq-dhcp[2369]: DHCPINFORM(usb0) ---

> [@codegit001](#): > > Success: iptables -A INPUT -s 192.168.0.0/24 --jump ACCEPT I’m really surprised to see some `192.168.0.0/24` in there. Seems like the subnet is wrong, as it should be `192.168.10.0/24`. It’s the case in the doc but not in `wifiApTest.c`. Could you see if that fixes the connectivity issue? Thanks ---

Now the laptop promptly display “Connected”; but even though I am able to ping data quite easily using my board, the connected device seems unable to do so. Also this is using static IP. Is there any way I can still use actual DHCP ? ---

The issue is now the fact that the board is not transferring data to its client. How can I use something like TFTP with the existing connection ? I enabled tftp client in my Windows 7 client, but the connections are timing out. tftp -l file.txt -p 192.168.10.1 tftp: timeout ---

Is there a tftp server on your target? There is none by default. Easiest way would be to use SSH (& SCP), but you would also need to open access to the target ssh port from wlan0. This would be something like: ```auto # Allow SSH, PING and DHCP over WiFi interface LAN_IF=wlan0 iptables -A INPUT -i @LAN_IF@ -p tcp -m tcp --dport 22 -j ACCEPT iptables -A INPUT -i @LAN_IF@ -p icmp -m icmp --icmp-type 8 -j ACCEPT iptables -A INPUT -i @LAN_IF@ -p udp --dport 67:68 --sport 67:68 -j ACCEPT ``` (adapted from `meta-swi/meta-swi-mdm9xxx/recipes-core/init-ifupdown/files/rules.v4`) ---

Any solutions on why the data cannot reach the client ? I am able to ping sites using the board; but the connected clients declare the Access Point as “No Internet Connection”. ---

@CoRfr after some snooping around, dropping the IP Tables just before resetting the modprob masquerade seems to do the trick; I was busy with another project, so I couldn’t pay attention to this. Cheers.
