So if you google for this chip, you can find, that it is a 16Mx16 chip, resulting in 32MB. As single. Theoretically it means, that this router (because of the one-chip design) could not be upgraded to 128, but 64MB.Originally Posted by Garluk
As it should be the actual case, as on the reference pictures linked by Serge (thanks) the chip on board is a Samsung K4H511638D what is used by many of us, giving 64MB/chip capacity.
So if you are interested in upgrading your router to 64MB the steps are the folowing:
- Check router board for missing resistors (if any), as on the previous boards A12 address line has not been implemented -it might be the case in the new version also.
- Cross check memory addressing parameters with Oleg, how to enable 64Mb on a single chip for v2 routers.
- Acquire a single Samsung K4H511638D or equivalent chip with 32Mx16 capacity (look above Inertial's post about compatible chips)
- Do the phisical upgrade (or better to ask someone with good soldering skills and a rework station to do is for you)
- Check it with Oleg's memtest
- Enable 64 MB
- Recheck
- Enjoy
Hope it helps.

status report: A friend of mine just finished upgrading the router sucessfully to 128MB, and also added connectors for the two additional USB ports with neat routing and proper coupling. I have finished installation of an external diversity antenna (instead of the PCB one) and installed 2x 5dB antennaes. :-) No dropped connection since, 54 Mbit/s maintained everywhere, fastest Wlan as ever with this router. :-)
