Tried both suggestions.
Davo, switched to regular network and NAS was found with a valid IP address on the network, but updater could not find a linkstation to update.
Looun, after TFTP program sent blocks and updater showed IP for NAS at 169.254.28.124. Tried running LSupdater and it cannot find locate NAS. Updater still shows ip address at 169.254.28.124. Tried changing PC address to same IP range to do firmware, but that resulted in not finding the NAS. Tried plugging in regular network cable and NAS pulled correct IP range address. Tried updating, but updater could not find device to update.
Have modified lsupdate.ini file to add version check and no formatting=0 and [SpecialFlags] debug=1
Tried changing NAS IP address using Nas Nav from TFTP folder and get message that IP changed and then denied because I have the incorrect password. Tried "password" and old unit password and it still failed.
Right now, blue light is steady and Buffalo NAS Navigator (1.20) shows 169.254.28.124, can't change it. NIC on PC is set to 192.168.11.1.
My wireless is disabled, AV and firewall turned off. Any ideas?
Should mention that I never get an options page for the firmware updater. Using file cloudstor-firmware-build-1.13-2.35.zip
Thanks.
UPDATE:
Went ahead and changed PC IP address to 169.254.28.123 and started the updater. Got message that couldn't confirm partitions. Said ok to format. Seems to format and then begin transferring firmware. Several files seem to move. Transfer of firmware completes, writing pauses and then it finishes. Message Linkstation has been rebooted. At this point get red error 6 flashes. Updater ver 1.13 shows "Waiting for finish of linkstation booting. Still flashing 6 red. Updater showing message, waited for 1200 seconds but had no response from linkstation. want to wait again? I'll say yes, but suspect I need to change PC IP? Still flashing 6 red. Will stop here for a while in case someone can help.

Re-read 2of5 and realized I had to right click on the upper border , select debug and I got the menu options for the updater. Set them as described, but it seems that the device switches IP addresses at random. I can get the updater to see the NAS when it has an ip in the 169.254.. range, but when I try to do the update itself, the device cannot be found. Light usually stays blue at this point, but NAS Navi shows device in EM mode. Should I just plug in the regular network cable and let it get an IP address from the router and then try the updater with a dhcp ip address?
Update 9/25/13
Changed NAS ip to my regular network and plugged it in. Started PC on regular network and disabled AV,firewall and windows firewall. Ran TFTP and blocks loaded. Ran lsupdater 1.13 with modified .ini file. Went through formatting and firmware updates and rebooted NAS. While waiting for it to come up, with red light flashing 6 times, it eventually timed out. Cannot find NAS. Blue light flashing on NAS. Re-booted NAS - had to remove power cord. Came back up with 169.x.x.x ip. Called buffalo tech support and they walked me back through procedures 2X. Got Tier 3 on phone and he confirmed actions and said that they had nothing else to offer.
Wasting too much of my time, and your, at this point to go any further. Expensive lesson to learn in terms of time and $$ outlay.
Thanks for your help.
