The Fonera 2.0g is the successor of the Fonera+ offered by Fon. Its an Atheros AP51 reference design, features a two-port fast ethernet switch and a USB 2.0 host port. Fonera+ and Fonera 2.0g are based on same hardware design, former lacking USB and having less memory.
This model is not sold anymore and has been superseded by the RaLink SoC based Fonera 2.0n.

Access to RedBoot is required for initial installation and recovery. The bootloader can be reached via serial cable or by Telnet on port 9000. Not all shipped units have RedBoot Telnet enabled by default, a serial cable might be required. While writing to flash, router will stop answering ping and you might lose Telnet connection. Leave ping running and reconnect Telnet when you receive an answer. Be patient as writing to flash takes several minutes.
You have to download two files, the .lzma
kernel image and the .squashfs
root filesystem image. You want the port from the atheros/
subdirectory, which was later renamed to ath25/
.
The latest images for Fonera+ (FON2201) are:

fileSome Fonera+ units don't have Redboot telnet access enabled by default, however it can be enabled by preforming the following steps:
ssh root@192.168.10.1 cd /tmp wget ftp://downloads.linwin-solutions.com/hxcwyxwr/fonera_openwrt/FON2202_2.2.5.0_Flipper_RedBootC_VoteGOP.image uci set registered.fonreg.dev=1 uci commit tar cvzf sysupgrade.tgz /etc/passwd /etc/group /etc/dropbear /etc/samba/smbpasswd /etc/samba/secrets.tdb /etc/config/firewall /etc/config/upnpd /etc/config/umtsd /etc/config/registered /etc/config/gdata /etc/config/facebook /etc/config/flickr /etc/config/mountd /etc/config/fon /etc/config/ddns /etc/config/wizard /etc/pureftpd.pdb /etc/pureftpd.passwd /etc/config/luci_dlmanager /etc/config/twitter /etc/config/firewall mtd -j sysupgrade.tgz -r write FON2202_2.2.5.0_Flipper_RedBootC_VoteGOP.image image reboot

If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you can upgrade using the sysupgrade utility. It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.

Serial ports settings are 9600@8n1.
The default network configuration is:

eth0.1 | LAN port (black) | Static |
eth0.2 | WAN port (white) | DHCP |

Because the FON2201/FON2202 has a build-in VLAN switch, unlike the FON2100. Connecting a VLAN trunk is a little different than usual. If you for example connect a trunk to the LAN port (eth0.1), then to access VLAN 5 on the trunk, you need the specify the device eth0.1.5 - Not eth0.5.
This practice is called double VLAN tagging. It usual requires that the MTU is lowered with 4 bytes. This is however not necessary on the FON2201/FON2202.
There is only one button, reset, at the bottom of the device.

The USB host controller suffers from a hardware bug, it will crash if a USB 1.1 device is attached. A workaround is putting a powered hub between the USB host and the device.
The picture above shows an annotated photo of Fonera+ (FON2201) PCB. Regarding antennas' connections it is quite similar to FON2200. The major difference being that the connections are inverted. On FON2201 antenna 1 is connected to the PCB etched antenna and antenna 2 to the stock external antenna. Therefore, in order to replace the etched antenna by an external one, you can follow the instructions for FON2200 but applying them on antenna 1 output.
