Hi,
Recently I purchased a RT5350F Olimex board. It seems to work fine.
By means of the openwrt web interface, I tried to configure the radio interface in order to enable it to connect to my domestic wifi access-point.
To this goal, I followed some suggestions found on the Internet.
The radio correctly associates to my AP and the dhcp client (on the Olimex board) gets IPv4 address, IP gateway and properly configures the Wlan0 interface and updates the routing table. I have checked firewall configuration and it seems OK.
Unfortunately, I cannot ping the other computers present in my network.
I monitored what happened by tcpdumping the LAN. ICMP packet requests arrive to the targetted PC, the latter sends back ICMP replies but these packets are not received by the Olimex board.
Please, may you help me.
Thanks in advance for any hints/suggestions.
Sandro
Hey,
It seems like the board's firewall rejects incoming traffic. Probably it has to do with OpenWRT's firewall configuration. Read more here: https://wiki.openwrt.org/doc/uci/firewall
It might be faster for people to spot problems if you post the network configurations of the board (/etc/config/wireless, /etc/config/network, /etc/config/switch, /etc/config/firewall, etc). Remember to remove passwords and MAC addresses when posting.

Hi Lub,
Thanks for your quick reply.
In the following my configurations files, specifically "network", "wireless", and "firewall". I have no switch configuration file since I removed the bridge interface.
I am looking forward to hearing from you.
Thanks a lot.
Best wishes.
Sandro
