My new fonera just arrived, but I noticed is a different model than the usual one.
It have a 7.5v 1A power supply, no heat dissipator and a slighty different pcb layout.
The kolofonium hack worked. I installed camicia kernel for get redboot access and all fine.
But in RedBoot the problems started. I first tried to install openwrt, but the first load failled:
Code:
RedBoot> load -r -v -b 0x80040450 openwrt-atheros-2.6-root.jffs2-64k
Using default protocol (TFTP)
Specified address (0x80040450) is not believed to be in RAM - continue (y/n)? y
Can't load 'openwrt-atheros-2.6-root.jffs2-64k': invalid parameter
RedBoot>
The "ver" command showed me that the ram address is not the same.
The old fonera:
Code:
Board: ap51
RAM: 0x80000000-0x81000000, [0x80040450-0x80fe1000] available
FLASH: 0xa8000000 - 0xa87f0000, 128 blocks of 0x00010000 bytes each.
And the new FON2200:
Code:
Board: FON1
RAM: 0x80000000-0x81000000, [0x80040aa0-0x80fe1000] available
FLASH: 0xa8000000 - 0xa87f0000, 128 blocks of 0x00010000 bytes each.
The ram starts at 0x80040aa0 instead of 0x80040450.
I tried to install the dd-wrt that uses the address 0x80041000 for the first load:

After reboot it, the commands to flash with dd-wrt worked fine.
The openwrt needs to change their commands because they start at 0x80040450 that is not inside ram address in new fonera and will give problems to newbie like me
But dd-wrt is ok because uses 0x80041000
The only problem (at least with my fonera) is that something seems to be buggy and the commands didnt work fine for me first time, maybe because the openwrt commands that tried to wite outside ram? But after a boot it worked fine
Now It seems to be the same as the old fonera except mine dont have any heat dissipator, and I have no serial interface, because the 4 pins seems not to be connected to the pcb
Is the new model fonera hot to the touch, or have they fixed that? Not having a heat sync and all...
They fixed it.
Under normal use I can touch the chip and its ok. Until heavy load maybe it will be a bit hot, but with a normal dissipator like the old fonera it will be fine. Or maybe it will survive withouth dissipator.
It seems that there are only one antenna, but in the lower left part it reads
ANT2 but I dont know where to solder it. Maybe in that small circle near the
serial number.
strange pcb geometry...maybe it's a internal disabled antenna?
I have a new fonera 2200, and i'm trying to dd-wrt it. I know how to flash a normal fonera, i did it 3 times, but i'm having problems with the new model.

I have the new Fon2200 and it may be an internal secondary antenna after all. Doesn't it make sense? You don't want to share internet with your neighbors, but you want FON to think you're online and keep privilages (let's pretend we didn't know about heartbeat workarounds). So you take off the antenna and the range drops. If there was an internal pcb based antenna this wouldn't work (assuming the thing was set to automatic switching). Also it is perpendicular to the other antenna's standard position so it alleviates problems with the a single omni antenna's dimensional dead spots (those being "over" and "under", above and below). The new fonera is better for portable applications since it needs less power and is more efficient. Its like an extra wireless card or a portable aircrack device. Let's see if I can compile MDK3 for it (DONE, http://www.dd-wrt.com/phpBB2/viewtopic.php?p=87015#87015 ).
