    After some tests on WRT54GX v2 with linksys GPL sources finally happend that after firmware upgrade the router does not work... When it starts the power led is blinking for some time, next ethernet link goes light and finally power led is going off and stays like that. The router does not respond to any pings. Long reset also did not help. Does anyone know is there any chance to upload any firmware image again? Is it possible to connect to it using a serial port? Thanks for any advice.

    Can you ping the WRT54GX through a wired connection after you power it up? Hopefully you were doing a firmware upgrade through a wired connection only. You should have reset the WRT54GX v2.0 to factory defaults before the upgrade.

    Unfortunately, I can not ping it at all (after/during power up, or reset...). Why should I reset the router to factory defaults before the upgrade? As I noticed, it resets to defaults if the new image version is different. And even if the versions are the same and something goes wrong with old settings then it is needed to reset to defaults - at least it worked so far in my case. But now, I don't have any idea how to get the router working... it is because I can't (or I don't know how) to have network connection to the router and that is why I am thinking of any other possible ways of connect to it...

    If you cannot ping it, you or reach it you cannot recover it. On the standard WRT54G routers, you can open them up and short the pins on the flash memory, but that is not true for the SRX series in an attempt to recover the router. The reason to reset the router to factory defaults before upgrading the firmware is that the setting are stored in memory and where it is stored may not correspond between firmware versions. This can cause the router to react unpredictably after the a memory upgrade or not to work at all. You should reset to factory defaults again after the firmware upgrade to clear any remaining setting. You should always do a firmware upgrade from a wired connection, since losing the wireless connection in the midst of a firmware upgrade can render the router inoperable.

    You should never used a saved setting from a prior firmware upgrade to restore the setting, since then again the setting may be stored in defferent locations in memory between firmware interations.

    If the router is unreachable you cannot tftp a new firmwar image to it. The SRX series of router do not have an executable firmware update either, which would help in router recovery.

    Unless you are upgrading the firmware to fix something, you should not update the firmware. Contact Linksys and unless you opened the router, you may get them to provide you with a RMA to get a new router, unless it is out of warrantee.

    Thank you for your advices - I'll keep them in my mind but with this router probably I will not use them ;-)
